Non Technical Summary
Production practices greatly impact productivity in black and red raspberries and primocane fruiting blackberries. Differences in row spacing, pruning techniques, training/trellising systems, the use of high tunnels and variety selections can result in wide yield differences between growers. Optimizing the production practices to maximize income is important for growers to stay competitive and profitable. However, little information is available to raspberry growers on different systems that may be suitable for their operations. In this project we will test 3 different practices under high tunnels that growers may be able to utilize to increase productivity including; 1) high density plantings of floricane fruiting black raspberries; 2) double cropping primocane red raspberries; and 3) training and producing primocane blackberries. Results of the trials will be disseminated among growers through grower group newsletters and extension publications through out region. In addition, field days will be held to provide growers an opportunity to see firsthand the practices being tested and allow for direct consultation on best practices for improved raspberry production.

Goals / Objectives
The NYS Berry Growers and North American Raspberry and Blackberry Grower Assocs. have identified high tunnel production systems and variety evaluations as top priorities for current research proposals. This project meets these goals and several FFF Global Food Security and Hunger goals including boosting agricultural production, assuring long-term viability of horticultural industries and rural communities, and optimizing production management to improve profitability and sustainability.Helping growers maximize productivity in the high value space under high tunnels is the ultimate goal of this project. Through this project growers will be able to compare standard production practices with 2 alternative practices, double cropping primocane red raspberry and high density black raspberry production. Additionally, primocane blackberry selections from the cooperative project between the University of Arkansas and Cornell berry breeding programs will be grown to demonstrate management practices for producing fall blackberries in the northeastern U.S.The research objectives of this project are to:1) compare the standard high tunnel production system for primocane red raspberry (fall production only) with a double cropping system (fall and summer production).2) compare the standard floricane black raspberry production system with a high density system (2 to 3 times various standard spacings) utilizing narrow rows, close in-row plant spacing, and precise cane training.3) evaluate advanced primocane blackberry selections from the joint U. Arkansas/Cornell breeding program in a high tunnel production system for harvest season, yield and fruit quality traits. Canes will be managed based on previous research to maximize productivity.
Project Methods
The multi-bay (1/2 acre) high tunnels currently available in the Cornell berry breeding program will be utilized for this study. Three reps each of five primocane varieties with suitable cane structure will be harvested using 2 systems, standard and double cropping. Standard production will follow the High Tunnel Raspberries and Blackberries guide (Heidenreich et al., 2012). The double crop system will utilize hand pruning for optimal floricane density with canes tied to a V-trellis to allow new primocane growth in the interior during floricane production.For black raspberry, 4 plots of 20 plants each of the varieties Jewel and Bristol with a density of 7260 plants/acre (6ft. row centers x 1 ft. within row) will be planted one tunnel using a vertical plane trellis to tie canes in a single plane along the row to a height of 7 ft. Spent floricanes will be pruned as the fruit is harvested and new primocanes tied simultaneously during the production season. The standard system in an adjacent tunnel will use 8 ft. row centers and 2 ft. plant spacing with a V-trellis with spring pruning.Primocane blackberry selections will be established in a V-trellis at 8 ft. row centers and 3 ft. plant spacing with 2 treatments, cane tipping for lateral production and flowering uniformity and untipped canes for early production. Total yields will be recorded and samples taken during each harvest week for post-harvest evaluation of shelf life, fruit size and quality aspects. Pest and nutrient management for all trials will be designed with the aid of the Raspberry and Blackberry Production Guide (Bushway et al., 2008).A field day will be held in the 2016 season to allow grower and CCE personnel to observe production systems directly and to provide production results for direct comparison of the systems. Oral and written information will be distributed at that time to present yield data and pest management procedures directly to growers. Reports will be submitted to grower, industry and CCE newsletters to keep stakeholders informed on the progress and results of the work. Oral presentations will be given at the NYSBGA annual meeting and at CCE fruit workshops each season.

Outputs
Target Audience:The target audience included growers, students, extension educators and researchers. Specifically, the members of the New York State Berry Growers Association, the North American Raspberry and Blackberry Association, and the USDA National Coordinating Committe-212 for Small Fruits and Viticulture as well as non-member growers in NY, mid-western, northeastern and mid-Atlantic states. Researchers and extension staff from Cornell and other leading institutions with programs in berry production, breeding and/or processing were also targeted. Graduate and undergraduate students at Cornell and elementary students from the Geneva, NY school system have also been provided information regarding berry breeding, production and nutritional content of berries in workshops and open houses. Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided?Multiple opportunities to interact with stakeholders and present information on the various training systems for raspberry and blackberry in high tunnels. These included the Cornell Berry Production Workshop on March 24, 2016 and the Cornell Fruit Field Day on July 20, 2016. On Sept. 10, 2016, a tour and lecture on the system was given to the Cornell Alumni Assoc. of Rochester. Sept. 17, 2016 a tour and lecture was given to Cornell Plant Breeding students and visiting scientists in the Humphrey Fellows and Alliance for Science Fellows programs. Attended the Empire State Producers Expo on January 21, 2016 to obtain the latest information on berry production, pest management and production technologies. How have the results been disseminated to communities of interest?The high density black raspberry planting was exhibited and explained at the Cornell Fruit Field Day on July 20, 2016 in a 20 minute session with 48 growers attending. The training system and pruning approach was demonstrated and data on yield and fruit size was presented to the growers. Growers were able to walk through the planting to see the system personally and ask questions about its implementation. Information on raspberry varieties and their suitability to different training systems including the high density black raspberry system and double cropping primocane red raspberries was presented to 26 growers and extension educators at the Cornell Berry Production Workshop hosted by the Saratoga County Cornell Cooperative Extension in Ballston Spa, NY. On Sept. 10, 2016 a tour of the high tunnel production system was provided to the Cornell Alumni Assoc. of Rochester for 90 attendees. Examples of various training and production systems including double cropping red raspberries, high density black raspberry production and primocane blackberry production were highlighted. On Sept. 17, 2016 a tour of the high tunnel production system was given to 36 Cornell Plant Breeding students and visiting scientists in the Humphrey Fellows and Alliance for Science Fellows programs. Examples of various training and production systems What do you plan to do during the next reporting period to accomplish the goals? Nothing Reported

Impacts
What was accomplished under these goals? The replicated high density black raspberry trial established in 2014 under high tunnels to test variation of training systems and planting density was harvested for the second season in 2016. Yield and fruit size were recorded at each harvest dates for all plots and used for calculating yield per area and mean fruit size over the whole season. Over a 2 year period, the high density planting had 68% and 39% higher yield for the varieties Bristol and Jewel, respectively, compared to control plots in the standard density plots with similar fruit size. The increased yield could be accounted for by the yield on 1st year canes in the high density planting. Since the plants produced few canes in the first year of growth, the standard planting had few productive canes for the first harvest. The high density planting is based on only 2 producing canes per plant, with more plants making up the difference. This allowed this system to become fully productive in the first year after planting. At local wholesale prices for black raspberry fruit of $6.75/lb, this yield increase would equal 50% of the cost of setting up the production system and allow growers to pay recoup their set up costs 1 year sooner.

The varieties Heritage, Double Gold, Prelude, Polka, Crimson Giant, Nantahala, BP-1 and Himbo Top all had significant fruit bearing potential for the summer season following fall harvest and could be managed in a double cropping system. Joan J, Autumn Britten, Caroline and Polka had insufficient cane area for a viable summer crop. Tulamagic and Nova did not have significant fall crops and would only be viable as summer varieties in the NY climate conditions. In blackberry, tipping versus non-tipping was evaluated across 3 selections from the breeding program. Tipping increased the number of fruiting laterals present thus increasing yield potential. In some cases, tipping delayed flowering and fruit ripening which could lower yields when cold temperatures are experienced early in the season. In 2016 the fall temperatures were late in arriving, thus the tipped selection had higher yields and the canes were a more manageable for picking than the untipped canes.
