Producers in northeast North Dakota depend upon improvements in cultivars to remain competitive in regional and world markets. The release of new improved cultivar is often a very effective form of rural economic development. Producers typically quickly adopt new cultivars of traditionally grown crops. This is an easy management change that can quickly improve productivity. Producers are continually searching for new crops production management strategies that will increase their efficiency and economic return per acre. Accepted practices are often modified in response to new economic scenarios, alternative crop uses, and changes in new technologies related to production. New cultural practices or agronomic inputs need to be research to insure that changes in present farming practices will increase both crop production and profitability for the producers. As crop management practices are refined, crop production becomes more efficient, enabling farmers to become more competitive in the market place. An integrated approach to this research is required and involves disciplines and scientists from the Research Extension Centers and related departments at NDSU. Replicated cultivar trials of named and experimental lines of small grain, row, oil and alternative crops were tested at the NDSU Langdon Research Extension Center (LREC) and off-station locations across northeast North Dakota during this project from 2009-2014. The crops, average number of locations and average number cultivars tested (number tested indicated in parenthesis) for the off-station locations for the time period were; hard red spring wheat (hrsw), four locations(25), durum wheat, one location (10), barley, two locations (7), conventional soybeans, one location (16), roundup ready (RR) soybean, three locations (66), liberty link (LL) soybean, one location (7) dry bean, one location (30). Crops and number of cultivars tested at the LREC were; hrsw (54), durum (49), hrsw uniform regional nursery (32), barley (24), oat (35), hrww (21), roundup ready (RR) canola (42), liberty link (LL), Clearfield (CL) and conventional canola (14), flax (31), field pea (19), dry bean (18), mustard (7), buckwheat (3), camelina (10), forages (10), RR soybean (63), conventional soybean (14), liberty link soybean (6), corn (40), oil sunflower (42), confection sunflower (18), and energy beets (7). Not all crops were tested every year. Many private company cultivar evaluation trials were conducted during the project, mostly canola and small grains. The LREC continued cooperation with North Dakota State University plant breeders of durum, hrsw, canola, corn and potato nurseries in addition to regional nurseries of several other crops annually. These nurseries test early generation and advance lines of crops to select the best lines that will be grown by producers in future years. In addition to evaluating small grain, row and alternative crop cultivars, this project evaluated integrated pest management and crop management cultural strategies that improve efficiency and profitability of crop production in northeast North Dakota. Some of the major research emphasis has been; Canola company seed treatments trials evaluating biological seed treatments for enhanced yield and seed treatments for flea beetles and seedling diseases, hrsw cultivar x fungicide trials to determine cultivar response to a foliar fungicide, canola planting date studies, canola seeding rate studies, and soybean seeding rate trials. Identify superior crop cultivars for northeast ND gives producers the information they need to switch to top performing lines. This is an easy and relatively inexpensive production practice which can result in increased income for producers. New cultivars and hybrids are developed yearly which need to be evaluated for their adaptation to the environment and soils of our region. The averages trial yields for the life of this project for the various crop in kg/ha were; hrsw 5261, durum 5162, barley 6711, hrsw regional nursery 5094, oat 6121, hrww 5384, canola RR 3247, canola conventional, CL and LL 3244, flax 2515, field pea 4994, dry bean 3099, mustard 2257, buckwheat 3012, camelina 2565, soybean RR 3207, soybean conventional 2953, soybean LL 2598, corn 7072, sunflower confection 2792, sunflower oil 2436 and energy beet 66.3 MT/ha with 18.1 percent sugar. Seed treatment trials were conducted on an annual basis for various companies to examined new product efficiency against flea beetle damage and seedling disease. Several products, along with the standard treatment of Helix Xtra, had higher yields and lower seedling disease in trials inoculated with the Rhizoctonia fungus. No significant differences in yield were observed from the use of biological seed treatments to increase yield in any of the trials conducted. A fungicide x cultivar trial was conducted over two years and examined the effect of Prosaro fungicide on over twenty hrsw cultivars. Yields were increased an average of ten percent, test weight two percent and DON was reduced by 65 percent. In a trial evaluating four fungicides on hrsw, Caramba applied 5-7 days after Feekes 10.51 growth stage provided the greatest yield increase and reduction in DON. A canola seeding date trials was conducted for three years with seeding dates ranging from the first of May to the middle of June. The first two years of the study yields were similar at all seeding dates or slightly higher at the later seeding dates. In 2012, the first two seeding dates had significantly higher yields than the later seeding dates. Although optimum seeding dates vary from year to year, the best management practice is seeding when soil conditions and temperatures allow for rapid germination. Soybean seeding rate trials were embedded in soybean cultivar trials at several locations during this project. Seeding rates ranged from 308,000 to 617,000 seeds/ha. Seeding rates appeared to have little effect on maturity dates while plant height, protein and oil percent differences among seeding rates were small and mostly non-significant. Combined results from the studies indicate that a seeding rate between 432,000 and 490,000 seeds/ha would result in optimum yields. A canola study examined the effects of seeding rates on yield and agronomic traits on a Roundup Ready and Liberty Link hybrid. Yield generally increased with the higher seeding rates. The 3 seeds/meter squared was significantly less than the 6, 9, 12 or 15 seeds/meter squared seeding rate. The data suggests that seeding between 9 and 12 seeds/meter squared would results in optimum yields and economic returns.

Replicated cultivar trials of named and experimental lines of small grain, row, oil and alternative crops were tested at the NDSU Langdon Research Extension Center (LREC) and off-station locations across northeast North Dakota during the project period in 2013. The crops, number of locations, and the number of cultivars tested (number tested indicated in parenthesis) for the off-station locations were; hard red spring wheat (hrsw), four locations (25), durum, one location (8), barley, one location (7), conventional soybean, one location, (11), Liberty Link (LL) soybean, 1 location (8), Roundup Ready (RR) soybean, three locations (64), drybean, one location (26). Crop cultivars tested at the LREC were; hrsw (49), durum (45), hrsw regional nursery (34), barley (25), oat (36), hrww (22), canola RR (36), canola LL and Clearfield (CL) lines (11), flax (30), field pea (11), drybean (26), soybean RR (54), soybean LL (5) soybean conventional (11), grain corn (36), oil sunflower (30), non-oil sunflower (30) and energy sugarbeets (6). Several private company cultivar evaluation trials were conducted for canola. In addition, private canola company trials evaluating biological seed treatments for enhanced yield and seed treatments for flea beetles and seedling diseases were also conducted. A soybean seeding rate study was conducted at two locations to determine the optimum seeding rate while a canola trial was conducted examining hybrid types and seeding rates. The second year of a weed control timing study in soybeans and evaluation of a nitrogen fertilizer product on hrsw were also conducted. Research results were presented in our annual research report which is given to county extension offices for distribution to producers in their county. Data is also posted on the Langdon website (www.ag.ndsu.edu/langdonrec) and provided to state extension specialists to include in state wide publications. Information was also presented to producers at the LREC field day and off-station tours at the four outlying sites. Research presentations were made during the winter months at various producer meetings. Identifying superior crop cultivars for northeast ND gives producers the information they need to switch to top performing lines. This is an easy and relatively inexpensive production practice which can result in increased income for producers. New cultivars and hybrids are developed yearly which need to be evaluated for their adaptation to the environment and soils of our region. This reporting period the top yielding hrsw cultivar across the locations was Faller which had an average yield of 6456 kg/ha. The mean for the trials was 5689 kg/ha. The top durum cultivar was Joppa which had an average yield of 6321 kg/ha. The mean of the trials were 5786 kg/ha. The top yielding barley cultivar was Celebration with a yield of 8731 kg/ha. The mean of the trials was 7236 kg/ha. The average yield of drybeans at two locations was 3294 kg/ha. The average yield for RR soybean at four locations was 2664 kg/ha, LL soybean at two locations 3523 kg/ha and conventional soybean at two locations 3207 kg/ha. Average yields for other crops tested in cultivar trials at the LREC were (in kg/ha); oat 7514, grain corn 6385, hrww 6281, hrsw regional nursery 6254, field pea 4821, flax 2509, canola LL and CL 4172, canola RR 4060, non-oil sunflower 4400, oil sunflower 4206, energy beets 65 MT/ha with 18.4 percent sugar content. The soybean seeding rate trials indicated that seeding rates between 432,400 and 555,750 pure live seed (pls)/ha would result in optimum yields. Biological seed treatments were evaluated in two separate canola trails. No significant differences in yield were observed between the treatments compared to the control. Three seed treatments trials on canola indicated that several compounds had significantly lower leaf damage compared to the untreated check under moderate flea beetle pressure. Yields of two compounds were significantly higher than the untreated check in one of the studies. Another study examined the effects of Rhizoctonia fungus on canola. Overall disease levels were low with no significant differences in yield between treatments and the untreated check. Root disease ratings exhibited lower levels for some compounds. A canola seeding rate by hybrid study indicated that the LL and RR canola hybrids responded similar to seeding rates for all traits examined. Yields increased with higher seeding rates, with the 32 pls/meter squared seeding rate significantly lower than the 97, 129, or 162 pls/meter squared seeding rate. The 64, 97, and 129 pls/meter squared seeding rates were not significantly different from one another. A hrsw fertility study indicated no differences in yield between urea and urea coated with a product to decrease nitrogen volatility. The average yields of four glyphosate spray treatments on soybeans resulted in a 1358 kg/ha increase in yield compared to the untreated check. Highest yields were obtained when weeds were sprayed at a height of 20 cm or less

This is an easy and relatively inexpensive production practice which can result in increased income for producers. New cultivars and hybrids are developed yearly which need to be evaluated for their adaptation to the environment and soils of our region. This time period the top yielding hrsw cultivar across the locations was Faller which had an average yield of 5379 kg/ha. The mean for the trials was 4869 kg/ha. The top durum cultivar was Alkabo and Carpio which had an average yield of 4640 kg/ha. The mean of the trials were 4552 kg/ha. The top yielding barley cultivar was Lacey with a yield of 5326 kg/ha. The mean of the trials was 4815 kg/ha. Average yields for other crops tested in cultivar trials at Langdon were (in kg/ha); oat 5656, grain corn 8875, hrww 4707, hrsw tri-state cooperative nursery 5037, drybean 3242, field pea 4229, flax 2176, canola Liberty Link and Clearfield lines 2352, canola RR 2352, non-oil sunflower 1989, oil sunflower 1931, soybean conventional 3227, and soybean RR 2871. Four fungicide treatments were evaluated on Prosper hrsw. Although disease levels were low, fungicide applications resulted in yield increases that ranged from 175 to 255 kg/ha with Stratego YLD and Prosaro having significant yield increases compared to no fungicide treatment. The soybean seeding rate trials indicated that seeding rates between 432,400 and 555,750 pls/ha would result in optimum yields. Foliar delivered micronutrients were evaluated on canola. No significant differences were observed among treatments for yield or any other agronomic trait. Seed treatment trials on canola indicated that several compounds had significantly higher yields and lower leaf damage compared to the untreated check under moderate flea beetle pressure. Another study examining the effects of Rhizoctonia fungus on canola found several seed treatments had significantly greater yields when compared to the untreated check for this seedling disease. A canola seeding date trial indicated that the April 27 seeding date had significantly higher yields compared to the June 1 and June 12 seeding date. Percent oil tended to decrease with later planting dates. Canola performed very well at the later seeding dates under the environmental conditions in 2010 and 2011. Although optimum seeding dates vary from year to year, the best management practice is seeding when soil conditions and temperatures allow for rapid germination. Energy sugarbeets were found to have an average yield and sugar content over six varieties of 59 MT/ha and 20.7 percent sugar, respectively. A hrsw fertility study indicated no differences in yield between Urea and Urea coated with a product to decrease volatility. Rainfall shortly after the top dress application probably negated positive yield outcomes. The average yields of four glyphosate spray treatments on soybeans resulted in a 2177 kg/ha increase in yield compared to the untreated check. Highest yields were obtained when weeds were sprayed at a height of 20 cm or less.

New cultivars and hybrids are developed yearly which need to be evaluated for their adaptation to the environment and soils of our region. This time period the top yielding hrsw cultivar across the locations was Prosper which had an average yield of 4976 kg/ha. The mean for the trials was 4294 kg/ha. The top durum cultivar was Lebsock which had an average yield of 4237 kg/ha. The mean of the trials were 3349 kg/ha. The top yielding barley cultivar was Rasmusson with a yield of 5595 kg/ha. The mean of the trials was 5241 kg/ha. Average yields for other crops tested in cultivar trials at Langdon were (in kg/ha); oat 5592, grain corn 7086, hrww 4236, hrsw tri-state cooperative nursery 4492, drybean 3418, camelina 2413, field pea 4344, flax 2628, canola Liberty Link and Clearfield lines 1917, canola RR 2571, non-oil sunflower 2927, oil sunflower 1981, soybean conventional 3846, and soybean RR 4263. The hrsw fungicide x cultivar trial evaluated four cultivars and four fungicide treatments. All cultivars responded similarly to the difference fungicide treatments for yield. Caramba fungicide applied 5-7 days after Feekes 10.51 growth stage was the best treatment with an increased yield of 6.7 bu/a and 2 ppm lower DON than the untreated check. This information will be useful to producers in determining fungicide effects on various cultivars. The soybean planting rate trials indicated that seeding rates between 175,000 and 200,000 pls/a would results in optimum yields. Seeding rate appeared to have little effect on maturity, plant height, lodging, protein and oil. Several private company disease trials were conducted on canola to determine the effect of fungicide on yield. Sclerotinia disease levels were moderate but there were no significant differences in yield between the various fungicides treatments. Sclerotinia disease severity index was significantly lower for Quash + Topsin and Proline fungicide treatments compared to the untreated check. Private company seed treatment trials on canola indicated that several compounds had significantly higher yields and lower leaf damage compared to the untreated check under moderate flea beetle pressure. A canola planting date trial indicated that the May 19, June 9 and June 16 planting date had significantly higher yields than the May 9 planting date. Percent oil tended to decrease with later planting dates. Canola performed very well at the later seeding dates under the environmental conditions in 2010 and 2011. A trial evaluating protein enhancement in hrsw indicated that 20 gal/a of 28 percent nitrogen and 9.5 gal/a of N-Demand applied at one-half kernel watery ripe stage resulted in protein increases of 0.5 and 0.7 percent, respectively, over the untreated check. Investigations of energy beets indicated an average yield and sugar content over six varieties of 26.5 tons/a and 20.7 percent sugar, respectively.

New cultivars and hybrids are developed yearly which need to be evaluated for their adaptation to the environment and soils of our region. This time period the top yielding hrsw cultivar across the locations was Faller which had an average yield of 5783 kg/ha. The mean for the trials was 5096 kg/ha. The top durum cultivar was Grenora which had an average yield of 5783 kg/ha. The mean of the trials were 5218 kg/ha. The top yielding barley cultivar was Rasmusson with a yield of 6779 kg/ha. The mean of the trials was 6333 kg/ha. Average yields for other crops tested in cultivar trials at Langdon were (in kg/ha); oat 6208, grain corn 8983, hrww 5594, hrsw uniform regional nursery 5218, drybean 3214, buckwheat 2686, mustard 2463, camelina 2408, field pea 5534, flax 3080, canola Liberty Link and Clearfield lines 3538, canola RR 3553, non-oil sunflower 2147, oil sunflower 2167, soybean conventional 2455, and soybean RR 3229. The hrsw fungicide x cultivar trial indicated that cultivars responded similarly to a 50 percent combination of the fungicides tebuconazole and prothiconazole. All twenty-one cultivars showed a significant yield gain from the use of the fungicides with an average increase of 511 kg/ha The range in yield gain was from 121 to 833 kg/ha for the most disease susceptible cultivar. Diseases in the trial included leaf spot and fusarium head blight. The fungicide application reduced the DON by an average of 1.6 ppm across the various cultivars. This information will be useful to producers in determining whether a particular cultivar should be sprayed with fungicides. The hrsw planting rate trial indicated that the 1.25 and 1.50 million pure live seed per acre seeding rate was significantly higher than the 1.0 million pure live seed per acre seeding rate by an average of 468 kg/ha. Several private company disease trials were conducted on canola to determine the effect of fungicide on yield. Sclerotinia disease levels were moderate but there were no significant differences in yield between the various fungicides treatments. Sclerotinia disease severity index was significantly lower for prothioconazole, metconazole and boscalid treatments compared to the untreated check. Private company seed treatment trials on canola indicated that several compounds had significantly higher yields compared to the untreated check under moderate flea beetle pressure. In two separate canola seed treatment trials inoculated with Rhizoctonia, Helix Xtra had the highest yields and stands compared to other seed treatments. A canola planting date trial indicated no significant difference in yield between five seeding dates ranging from April 29 to June 9. Percent oil decreased as planting dates were delayed from April 29.

This is an easy and relatively inexpensive production practice which can result in increased income for producers. New cultivars and hybrids are developed yearly which need to be evaluated for their adaptation to the environment and soils of our region. This time period the top yielding hrsw cultivar across the locations was Faller which had an average yield of 6052 kg/ha. The mean for the trials was 5399 kg/ha. The top durum cultivar was Grenora which had an average yield of 5648 kg/ha. The mean of the trials were 5110 kg/ha. The top yielding cultivar of the barley was Pinnacle with a yield of 7155 kg/ha. The mean of the trials was 6895 kg/ha. Average yields for other crops tested in cultivar trials at Langdon were (in kg/ha); oat 5920, corn 4032, hrww 6740, hrsw uniform regional nursery 3939, drybean 2617, buckwheat 3339, mustard 2051, camelina 2875, field pea 6023, flax 2270, canola conventional 3476, canola RR 3393, non-oil sunflower 1807, oil sunflower 1339, soybean conventional 2455, soybean RR 3229, cool season forge 8.7 MT/ha and warm season forge 8.6 MT/ha. The fungicide x cultivar trial indicated that cultivars responded similarly to a 50 percent combination of the fungicides tebuconazole and prothiconazole. This year all twenty-two cultivars showed a significant yield gain from the use of fungicides with an average increase 639 kg/ha The range in yield gain was from 341 to 1139 kg/ha for the most disease susceptible cultivar. The major disease in the trial was leaf spot. This information will be useful to producers in determining whether a particular cultivar should be sprayed. The hrsw planting rate trial indicated that the 1.25 and 1.50 million pure live seed per acre seeding rate was significantly higher than the 1.0 million pure live seed per acre seeding rate by an average of 538 kg/ha. Several private company disease trials were conducted on canola to determine the effect of fungicide on yield. Sclerotinia disease levels were moderate but there was no significant difference in the disease severity index or yield among fungicide treatments. This may have resulted from a delay in disease progression and fungicide losing their efficacy by the time the disease was present. Private company seed treatment trials on canola indicated that all treatments had no significant difference on yield even though differences were seen in flea beetle damage and/or plant stands. The very cool growing season allowed damaged plants to recover fully and produce nearly identical yields as those with lesser amounts of flea beetle damage and/or stand reductions.
