Progress 04/01/24 to 03/31/25
Outputs
Target Audience:Due to the impact of changing weather patterns on food production, the project has attracted attention from a wide range of audiences. These include rice growers, researchers from the U.S. and abroad, undergraduate and graduate students, farm consultants, extension agents, high school students and teachers, policymakers, state commodity board members, and consumers. Several Co-PDs participated in field days, demonstrations, consultant meetings, and producer meetings across multiple states. They emphasized the background and significance of the ongoing research, which focuses on developing stress-tolerant rice varieties, promoting environmentally sustainable production practices, and applying digital technologies to enhance the sustainability and profitability of rice farming. A two-week Camp-CRISP workshop was organized for high school students and teachers. The PD,Co-PDs, graduate students, and postdoctoral researchersdelivered poster and oral presentations at various conferences and technical working group meetings, engaging audiences such as researchers, rice growers, rice industry professionals, USDA scientists, consultants, and extension personnel. Our regularly updated CRISP-RICE website and active social media participation have further supported public engagement and dissemination of project activities and updates. Changes/Problems:During the reporting period, Co-PDDr. Parvejdeparted from the LSU Agricultural Center. A graduate student will carry out his research responsibilities under the joint supervision of Dr. Tubana and Dr. Subudhi. However, student recruitment of this student is currently on hold due to a university-wide hiring freeze. Additionally, two graduate students departed from the laboratories of Drs. Reddy, Rangappa of the Mississippi State University, and Dr. Schafer of the LSU Agricultural Center. New graduate students have since been recruited to fill these positions. Following the external evaluator's untimely passing, project evaluation responsibilities were reassigned to Dr. Sam Robison of LSU from the Social Research and Evaluation Center. Although evaluation documents were submitted to the SAS Program Leader of NIFA last year, formal approval was not granted until February 2025, resulting in delays in the evaluation process. Furthermore, the proposed LSU japonica diversity panel was replaced due to significant variation in heading dates. A new japonica panel, sourced from the Dale Bumpers National Rice Research Center at USDA-ARS, is now being used. This panel is currently being multiplied in Puerto Rico by Co-PD Dr. Deguzman of the University of Arkansas for use in genome-wide association studies (GWAS) focused on identifying genes for tolerance to various abiotic stresses. What opportunities for training and professional development has the project provided? The project has provided training and professional development opportunities for 25 graduate students across a wide range of research areas - physiological and genetic mechanisms of abiotic stress tolerance, metabolomics and lipidomics, artificial intelligence, genetics and biological control of resistance to pests and diseases, application of precision agriculture tools, disease forecasting, cover crops, and the socio-economic impacts of climate-smart technologies. These students received mentorship and guidance from CRISP-RICE researchers at participating institutions.In addition, three postdoctoral fellows are supporting key research activities in the areas of bioinformatics, genome engineering, and disease resistance. Four research associates have been trained in evaluating mapping populations and a diversity panel under varying abiotic and biotic stress conditions. An extension associate is responsible for coordinating all extension and outreach activities. This includes organizing the Camp-CRISP workshop, designed for high school students and teachers, as well as the Rice Production School. Six students and four teachers participated in the two-week Camp-CRISP summer workshop during the reporting period, Participants visited research stations, including the Rice Research Station in Crowley, Louisiana, and toured several laboratories on campus. The program covered diverse topics such as artificial intelligence in agriculture, development of resilient rice cultivars using modern genomics and molecular breeding tools, rice disease and insect-related research, and the application of digital agriculture technologies. Students had the opportunity to engage directly with ongoing research and interact with key stakeholders involved in the CRISP-RICE project.Furthermore, the project facilitated participation of CRISP-RICE team members, including graduate students, in various workshops, conferences, seminars, and field days, thereby enhancing their technical knowledge and professional development. How have the results been disseminated to communities of interest?The findings from this project were disseminated through multiple channels to reach target audiences effectively. CRISP-RICE researchers produced 19 peer-reviewed publications, 69 poster and oral presentations, five abstracts, and five non-refereed articles. These dissemination efforts included contributions from faculty, graduate students, and postdoctoral researchers. Posters and oral presentations were delivered at the following meetings, workshops, and conferences, ensuring broad visibility and engagement with scientific and stakeholder communities. These events provided platforms for sharing research progress, methodologies, and key outcomes with fellow researchers, industry representatives, extension personnel, and producers.

The CRISP-RICE project website continues to be regularly updated to share new content with stakeholders and producers, highlighting key findings and accomplishments from ongoing research. This content includes videos and podcasts designed to improve stakeholders' understanding of stress-tolerant cultivars, emerging technologies, and available resources to enhance rice production systems' profitability and sustainability. The LSU AgCenter Rice Production School curriculum has been developed, with over a dozen participants enrolled. The program consists of six sessions over two consecutive days each month, from April through October 2025. Additional key methods of disseminating project results include participation in field days, working group meetings, consultant meetings, and live demonstrations, all of which serve to engage stakeholders and extend the impact of the research. In Louisiana, a series of winter regional extension and summer producers' meetings were held to help rice producers prepare for the upcoming growing season. These events attracted between 50 to 100 rice growers and other stakeholders. Participants were invited to visit active research sites, including LSU AgCenter out-field trials conducted at research stations and commercial farms across the state. Several rice field days were organized to serve different regions. CRISP-RICE extension personnel and researchers provided updates on new rice varieties, insect and disease management strategies, and environmentally sustainable production practices. In addition, a precision agriculture event was held at the Callegari Center of the LSU AgCenter Central Research Station, involving five Agricultural Residential College students and two mentors. In Mississippi, six on-farm verification programs were implemented across the Mississippi Delta to demonstrate water-saving irrigation practices. The Mississippi Master Irrigator program, attended by approximately 60 participants, provided training on irrigation water management, soil health, and irrigation system maintenance. Other extension efforts included rice variety trials to assess agronomic performance, participation in the Delta Area Rice Meeting (~70 attendees), the Mississippi Agricultural Consultants Association Meeting (~200 attendees), the Spring Rice Planning Meeting (~50 attendees), appearing as guest hosts on the Mississippi Crop Situation podcasts, and presentations on irrigation automation at the 28th Annual National Conservation Systems Cotton and Rice Conference. Contributions were also made to the 2024 edition of the Mississippi Irrigation Manual, a key extension publication. At the University of Arkansas Rice Field Day, attended by approximately 350 rice growers, CRISP-RICE researchers shared updates on rice variety development, rice water weevil research, and efforts to enhance drought and heat stress tolerance in rice cultivated across the southern U.S. rice belt. Two in-service trainings were organized to address rice water weevils and the effects of irrigation strategies and cultivars. Outreach also included five podcast episodes delivered via Row Crop Radio and the Syngenta Pest Patrol Hotline and a published research report in the BR Wells Rice Research Series. In Texas, project findings related to rice disease control were disseminated through field tours and oral presentations during two field day events held in Eagle Lake and Beaumont. These events engaged both farmers and students. Additionally, a working group meeting focused on Texas rice disease management brought together County Extension Agents from the Texas Western and Eastern Rice Belt regions to share research updates and gather feedback on regional rice management challenges. An extension publication, Rice Kernel Smut Factsheet, was prepared and distributed to Texas rice producers. Awareness of rice kernel smut disease was further enhanced through an interview featured in AgriLife Today, Texas A&M AgriLife's digital magazine and news outlet. What do you plan to do during the next reporting period to accomplish the goals?The following activities are planned under four objectives.

Impacts
What was accomplished under these goals?
Objective 1: Two irrigation practices such as furrow irrigated rice and alternate wetting and drying (AWD) were incorporated into the Louisiana rice costs and returns model. The estimated net return under a risk-neutral condition was the highest in the hybrid flooded system, followed by the hybrid furrow irrigation system, the conventional flood irrigation, the hybrid AWD, and the conventional AWD. It is concluded that any decrease in yield can negatively impact AWD adoption. Risk premiums to offset this negative perception could incentivize grower adoption of AWD. The majority of the groundwork for the survey of rice growers in the five rice-growing states to investigate the socioeconomic impacts of modern technologies was completed using input from USDA-NASS personnel and extension personnel, and the survey was approved by the Institutional Review Board (IRB). Objective 2: Evaluation of advanced breeding lines for drought tolerance at the flowering stage identified 63 resistant and 99 moderately resistant lines. A QTL-Seq analysis detected 7 genomic regions, and 14 candidate genes were selected for validation. Heat tolerance evaluation at the flowering stage indicated higher tolerance in N22 and Akitokomachi compared to Cocodrie. A genome-wide association study (GWAS) in an Aus diversity panel identified promising accessions with the early morning flowering trait and identified candidate genes with roles in flowering time modulation. Analysis of whole genome and transcriptomic sequencing data of a salt-tolerant introgression line revealed the collective contribution of genes involved in diverse pathways, such as transporters, ion channels, transcription factors, ABA response, and calcium-mediated signaling cascade toward salt tolerance. This line showed greater resilience to salt stress in a trial conducted at Clemson University. A comparative analysis of salt-tolerant and susceptible lines identified a subset of genes implicated in salinity stresses encompassing high-impact mutations. A GWAS study of the LSU japonica panel for cold tolerance detected 64 loci. The genotypes with the highest positive and lowest negative responses to eCO2 were identified. The evaluation of this panel under drought stress during the vegetative stage indicated a significant reduction in stomatal conductance, transpiration, and many morphological traits. Raman spectroscopic analysis revealed significant biochemical changes, primarily affecting lipid metabolism, membrane composition, and protein conformation under salt stress. Untargeted metabolomic profiling indicated an elevated shikimic acid, salicylic acid, ribitol, and L-aspartate-semialdehyde levels in the salt-tolerant line. Evaluation of mapping populations under AWD indicated many enhanced water-use-efficient lines. A new japonica panel was multiplied in Puerto Rico for drought and heat stress tolerance studies. A computational framework using artificial intelligence (AI) was developed to simulate the procedure to determine the desirable combination of genes usingdirected evolution. Analysis of the field data of a RIL population identified 5 QTLs associated with the NA2-seed-priming-induced resistance to bacterial panicle blight (BPB) and 3 QTLs without NA2 seed-priming resistance. Candidate disease resistance genes were identified. Genotyping and evaluation of a multiparental population identified four lines with acceptable lodging traits for introgression of RBG2. Field evaluation identified Arkrose, Saturn, Zenith, Vista, Jupiter, and Roy J as resistant to kernel smut. Thirty isolates of the kernel smut fungus were collected from Texas and Louisiana. Applying fungicide to control kernel smut was best at mid-boot stage. Objective 3: The sensor-based nitrogen (SBN) technology indicated no benefit in improving rice productivity in a field trial. Grain yields in field trials were similar irrespective of silica (Si)application. A pot experiment showed no benefit from silica solubilizing bacteria (SSB) inoculation even in the presence of slag and wollastonite, possibly due to inherently high soil Si. However, the addition of either slag or wollastonite raised the soil Si almost 2x the initial soil Si, regardless of SSB inoculation, and sustained a significantly highsoil Si at a later stage. A model was developed to predict yield as a function of remote sensing and agronomic data using AI. Initial evaluation indicated that the model using the XGboost option had the highest accuracy. At the time of cover crop termination, the cover crop mix treatment had slightly higher nutrient levels than the fallow treatment, and the difference became less after rice harvest. The cover crop promoted microbial abundance in the soil more than the fallow treatment. The rice crop showed lower yield with cover crop treatment, suggesting other factors may influence rice growth besides soil health parameters. Field trials indicated PVL03 as the most susceptible variety, and Mermentau and Cheniere were less susceptible to the stem borer. The use of Cruiser and Fortenza to control rice water weevils resulted in higher levels of whiteheads than in untreated plots later in the season. Dermacor failed to reduce whitehead densities significantly. Multi-year studies revealed minimal benefit of the insecticidal seed treatments for ratoon cropping. Reduced efficacy of insecticidal seed treatments in several on-station and on-farm trials raised concerns about the development of resistance. Alternative management strategies are needed to control the water weevil due to the poor efficacy of seed treatments. Rice mutant lines with reduced ability to take Sifrom soil revealed the critical role of Si in providing resistance against stem borers and brown spot but not rice water weevil and rice stink bug. A cover crop study failed to show any beneficial effect in reducing rice water weevil or stem borer infestation. A field trial in Arkansas revealed no difference in rice water weevil larvae between AWD and continuous flooding. Hybrid cultivars tended to have more water weevil larvae. Seed treatments performed equally well in both irrigation strategies. A meta-analysis study using historical data indicated relatively good efficacy of the fungicides in maintaining yield and reducing sheath blight infection. But no significant effect was observed for milling yield. The engineered NA2 showed similar efficacy as avirulent NA2 in suppressing ShB disease through seed treatment. A transcriptome analysis identified differentially expressed genes in defense-related pathways. Objective 4: Louisiana extension and outreach activities included organization of a summer workshop for high schoolstudents and teachers, updating of CRISP-RICE website, preparation of extension videos for rice growers, maintaining a presence on social media, news releases and articles about CRISP-RICE, preparation for the Rice Production School, and participation and providing updates in numerous producers meeting, field days, and conducting a precision agriculture event for college students. In Arkansas, activities included participating in field days and presenting updates on rice varieties, water weevil control, and drought and heat tolerance research. Two In-service trainings and five podcasts through row crop radio and the Syngenta pest patrol hotline were organized. Texas extension activities included presentation on disease management in field days, organizing a working group, survey of diseases and insect pest outbreaks, and preparation of a 'Rice Kernel Smut Factsheet'. In Mississippi, six on-farm verification programs about water-saving practices were implemented, rice varietal trials were conducted at six sites, and the Mississippi Master Irrigator Program was hosted. Other activities included participation in the Mississippi crop situation podcast, presentations in several extension county meetings, and contributions to the Mississippi Irrigation Manual.

Progress 04/01/23 to 03/31/24
Outputs
Target Audience:This project has a wide range of target audiences due to the increased awareness among the public regarding the impact of climate change on food security. These audiences are rice growers, researchers from the USA and other parts of the world, graduate and undergraduate students, farm consultants, extension agents, high school students and teachers, policymakers, state commodity board members, and consumers. Students were enrolled in seminars focusing on climate change and food security. Several Co-PDs participated in field days, demonstrations, consultants' meetings, and producers' meetings in multiple states and highlighted the background and importance of the ongoing research on the development of climate-resilient varieties, climate-smart production practices, and application of digital technology for improving sustainability and profitability of the farming enterprise. High school students participated in lab activities of a Co-PD with expertise on artificial intelligence during the summer of 2023. The PD and Co-PDs presented posters and oral presentations in meetings and technical working group meetings where the audiences were researchers, rice growers, members of the rice industry and USA Rice Foundation, USDA scientists, consultants, extension agents, personnel, and graduate students. Development of the CRISP-RICE Website and participation in social media (Facebook, Instagram, podcasts) helped us to engage with the public about the project activities and updates. Changes/Problems:Since the processing of sub-awards took some time, there was a delay in the start of the project activities. Two of our Co-Project Directors from LSU Agricultural Center and one from Mississippi State University left the organization during the reporting period. MSU already assigned Dr. Drew Gholson in place of Dr. Hunter Bowman. Lisa Fultz's activities are assigned to Dr. Jim Wang of the School of Plant, Environmental, & Soil Science of the LSU Agricultural Center. The approval for these changes from the SASProgram Leader is pending. In the case of Dr. Luciano Shiratsuchi, his funds will be used for the Project Evaluation Work which will now be done by Dr. Samuel Robison of the LSU Social Research and Evaluation Center. The processing of this sub-award is under process for getting internal and SAS Program Leader's approval. Since we already have one Co-PD with precision Agriculture expertise, this change will not impede our effort to accomplish the overall goal of the project. The recruitment of a postdoc with bioinformatics experience was slowed down because the selected candidate could not get a visa. We had to redo the searchand finally recruited the postdoc in December 2023. There was a delay in getting the Material Transfer Agreement to procure the japonica diversity panel from the LSU AgCenter Rice Research Station. Since few seeds were provided, the Project Director distributed the seeds to CO-PDs at Mississippi State University and the University of Arkansasfor multiplication. After growing the panel, it was found that there is a great deal of variation in flowering which will be a major obstacle to evaluating different types of abiotic stress evaluation. The Co-PD at the University of Arkansas is in the process of getting a tropical japonica panel from the USDA-ARS Dale Bumpers National Rice Research Center. This will be multiplied again in 2024 before the screening for abiotic stresses can be conducted. What opportunities for training and professional development has the project provided?The project provided training and professional development opportunities for nineteen graduate students who are working on the different research components including physiological and genetic mechanisms of abiotic stress tolerance, metabolomics and lipidomics, artificial intelligence, genetics and biological control of resistance to pests and diseases, application precision agriculture tools, forecasting of diseases, cover crops, and socio-economic impacts of climate-smart technology under the direction of the researchers from participating states in this project toward the development of climate-resilient varieties and climate-smart production practices. Three postdoctoral fellows were recruited to conduct bioinformatics and disease resistance research activities. Two research associates in this project will be trained in the evaluation of mapping populations and a diversity panel under different abiotic stresses such as salinity, drought, and heat stresses. Two high school students worked during the Summer of 2023 to learn about artificial intelligence in the lab of a Co-PD. A single credit-hour "journal club" course was developed in the CRISP-RICE project in which twelve students enrolled in the course in Spring 2024 to learn about agricultural sustainability through presentations and discussions of their work and updated literature associated with it. The project also provided opportunities to members of the CRISP-RICE including graduate students to participate in workshops, conferences, seminars, and field days, to enhance their knowledge and for professional development. How have the results been disseminated to communities of interest?The findings from this project were disseminated in multiple ways to reach the target audiences. There were 14 peer-reviewed publications, and three abstracts published by the members of the CRISP-RICE group. The CRISP-RICE researchers including the graduate students and postdocs made eighteen posters and oral presentations in multiple meetings and conferences: ASA-CSSA-SSSA Annual Meeting.

We developed the CRISP-RICE Website (https://www.lsuagcenter.com/topics/crops/rice/crisp-rice), and participated in podcasts, and radio talk (NPR) to educate the public about the importance of thisproject and the research conducted by our group to improve sustainability of rice farming. We are also maintaining our presence on social media to update the activities and events. Multiple Extension videos on climate-smart technologies were circulated through YouTube and several articles were published with LSU AgCenter and popular news outlets for the benefit of the stakeholders. Other important modes of disseminating the results from the project to the stakeholders are through participation in field days, working group meetings, consultant meetings, rice production school, and demonstrations. During this reporting period, Extension personnel in Mississippi organized five county production meetings, two rice planning and Delta rice meetings, and participated in seven podcasts. In the University of ArkansasRice Field Day, stakeholders were invited to see the demonstration plots for the impact of irrigation strategy on insect infestations. Contacts were made through in-person contacts (~500) and podcasts (~2500). During the field day, the USDA-ARS Co-PD highlighted the background and importance of the USDA-NIFA project's ongoing research work for drought and heat stress tolerance. During two rice field events Eagle Lake and Beaumont, Texas, the project findings were disseminated through field tours and oral presentations to stakeholders. A working group was organizedin Texas for extension agents of Texas for rice disease management. In Louisiana, climate-smart information was presented at several meetings including Parish Rice Production meetings, the Louisiana Consultants meeting, the Supreme Climate Smart meeting, and several field days. Each meeting ranged between 50 to 500 stakeholders and farmers. The benefits of alternative wetting and drying techniques, cover cropping, and the use of precision agriculture in current and future rice growing were discussed. What do you plan to do during the next reporting period to accomplish the goals?The following activities are planned for the next reporting period under all four objectives.

Impacts
What was accomplished under these goals?
The project accomplishments are summarized below under different objectives. Objective 1: We developed enterprise budgets for a representative rice farm that models the cost structure of alternative irrigation water management strategies: conventional flood, furrow irrigation, and alternative wetting and drying (AWD). Both discussions and interviews were held with stakeholders to gain an understanding of the trends, variations, and core issues, identify barriers to the adoption of climate-smart technologies, and obtain a representative sample of rice growers for conducting the survey. Objective 2: Seed increase of several mapping populations was done for genome-wide association studies (GWAS). An aus panel was procured from USDA-ARS for early morning anthesis and other desirable heat and drought tolerance traits. We collected leaf samples of salt-tolerant and susceptible genotypes for metabolomics, lipidomics, and Raman spectroscopic analysis. The protocol for extracting lipids and metabolites from leaf samples was standardized. We performed NMR and LC-MS to identify the metabolites and lipids after salt stress. We performed literature searches to identify the Raman molecular signature for plant leaves. We used EnsembleVEP to predict the functional consequences of genetic variants on the RGAP database (Nipponbare) and STAR to determine mutable components. Analysis of the whole genome sequence and RNA-seq data of a salt tolerant introgression line (IL), donor Nona Bokra, and recurrent parent Jupiter revealed 14 and 25 differentially expressed genes (DEGs) in the introgressed regions of the IL under control and saline conditions, respectively. The DEGs included genes belonging to DREPP family, sialyltransferase-like protein, cyclin-like F-box family, CELL WALL INVERTASE 1, and OsbZIP71, which were upregulated only in the IL and Nona Bokra but downregulated in the Jupiter under saline conditions suggesting their role in enhanced salt tolerance. The japonica panel was screened for early-stage low-temperature stress in growth chambers and for response to variable Co2 concentration using the Soil-Plant-Atmosphere-Research (SPAR) facility. Compared to the control, there was a detectable reduction in stomatal conductivity, electron transport rate, chlorophyll content, and nitrogen balance index.Two introgression line mapping populations were planted at Stuttgart for seed increase to conduct the alternate wetting and drying (AWD) studies. The japonica panel was grown at the greenhouse of the University of Arkansas Rice research station and LSU AgCenter Macon Ridge Research Station.Due to the wide variation in flowering time, it would be challenging to conduct field trials to evaluate tolerance to drought and heat stress. We are exploring an alternative panel from the USDA-ARS. A breeding line with enhanced seedling stage salt tolerance along with Jupiter was evaluated under varying concentrations at the Clemson University Coastal Research and Education Center (CREC). The line showed better adaptability capacity to maintain productivity in high-saline conditions. A major QTL for bacterial panicle blight (BPB) resistance was identified using bulked segregant analysisin the population developed from the Lemont x LM-1 cross. The whole genome sequences of Lemont and LM-1 (mutant) were generated and SNPs and indels were identified, filtered, and annotated to identify putative genes for BPB resistance. In a multi-parental population,genotyping with markers associated with each of the two QTLs (RGB2 of Kele and qBPB3.1 of Jupiter) resulted in the identification of plants with different QTL combinations. We identified kernel smut-resistant rice varieties. Hybrid varieties showed better resistance to kernel smut. Fifteen more isolates of kernel smut fungus were collected from Texas and Louisiana. The mid-boot was the best time and fungicides, Amistar Top, Tilt, and Dithane M-45, were equally effective for control of kernel smut in a field trial. Objective 3: We evaluated the sensor-based nitrogen technology (SBN) at two production fields, one under the rice-soybean and another under the rice-crawfish rotation system. Crop performance was better in SBN-adopted fields. Experiments using silica-solubilizing bacterial (SSB) strain indicated higher grain yield with the application of silicon in both rice-soybean and rice-crawfish rotation. Although cover crops experiments were established at three locations, rice could not be planted due to climate issues. We analyzed data from 37 separate field experiments conducted in Louisiana and concluded that varietal resistance can be incorporated into integrated management programs to reduce reliance oninsecticides. We are characterizing volatile emissions from rice panicles at various stages of panicle maturation and exploring the effects of these volatiles on bug behavior. The evaluation of two mapping populations revealed significant variation in susceptibility to rice water weevil (RWW) and Mexican rice borer (MRB). Cover crops were plantedtwo locations to investigate the impact of cover cropping on insect pest management in rice. The insecticidal seed treatments reduced the RWW and MRB infestation by approximately 50% in May-planted rice relative to March-planted rice. A separate multi-year study revealed insecticidal seed treatments provided minimal benefit to ratoon crops and foliar application of insecticides did not influence yields of the ratoon crop. Trials conducted in Arkansas revealed that there were more rice water weevil larvae in the AWD plots compared to the flooded plots and hybrid cultivars had increased infestation with RWW larvae. Seed treatments performed equally well in both irrigation strategies. Using transcriptomic analysis, we identified major rice genes involved in regulations of stress response and broad-sense resistance that were specifically induced upon seed treatment of the bacterial agent NA2. Greenhouse tests were conducted with the same RIL population to confirm the phenotypes evaluated in the field.We consolidated the historical data on disease intensity, yield, and grain quality into a single dataset. A new protocol to classify varieties' disease reactions was developed. This protocol uses the accuracy component of the breeder's equation combined with multiple mixed models to eliminate studies with low accuracy and to use the stability of the assessment. In a trial to evaluate nitrogen-use efficiency (NUE), both remote and proximal sensing techniques were used to collect data on plant height four times during the growing season and yield data at maturity. The remote sensing data collections were done at one on-farm location to complement the data at the Rice station. This experiment demonstrated UAV remote sensing as a promising technology to generate plant height data including time series data during the growing season and to examine detailed spatial variability in the field. We initiated evaluating machine learning technique-based image processing for efficient evaluation of crop stand density in the field. Objective 4: We conducted UAV demonstration at two locations in Louisiana. A web page for the project was developed. We produced 20 news releases and articles. Demonstrations showing the impact of irrigation strategy on insect infestations were organized for stakeholders in Arkansas. Texas extension activities included presentations on field days. The rice growers in Mississippi learned about water-conserving irrigation strategies in different meetings. Climate Smart information was presented at several meetings and field days. The benefits of alternative wetting and drying techniques, cover cropping, and the use of precision agriculture were discussed. Best management practices were followed in five rice research verification fields across Louisiana. Extension videos were produced, and articles were published with LSU AgCenter and other popular news outlets.
