Download or read book Cover Crops Drought Yield and Risk written by Fengxia Dong and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Besides a variety of production and environmental benefits, cover cropping has been advocated as a mean to increase resilience to drought. We explored factors influencing farmer's adoption of cover crops and examined the effects of cover crops on soybean yield and its risk using USDA's 2018 ARMS Phase II Soybean Production Practices and Costs Report and Phase III Soybean Costs and Returns Report. Incorporating drought occurrence in current year and previous 5 years into our analysis, we find that previous occurrence of drought did not affect farmers' adoption of cover crops and the effects of cover crops on yield and its risk are mixed. Under a drought condition, cover crops reduced soybean yield and increased yield variation; but in the meantime, they reduced the risk of crop failure, or made yield less negatively skewed. The insignificant effect of previous drought on cover crop adoption and the mixture of positive and negative effects of cover crops on yield and its risk imply that farmers are divided in their acceptance of cover crops as a mean to build resilience to drought.

Download or read book Increasing Yield of Late planted Soybean Through Management Practices in the Southern Great Plains written by Alexandre Stefani Barreiro and published by . This book was released on 2014 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increased soybean commodity prices and high-yielding cultivars have instigated producers to expand soybean production outside traditional regions. Introduction of soybean to relatively new areas such as the Southern Great Plains, has created the need for management practices unique to the region to exploit full yield potential in these environments. Oklahoma soybean production, for instance, frequently results in low yields due its adverse environmental conditions, along with common late-plantings, as a double crop following wheat harvest. Due to soybean photoperiod sensitivity, delayed planting leads to a shortened vegetative growth period, which potentially reduces seed yield. The influence of management practices, such as seeding rate, row spacing, maturity group selection, starter and foliar fertilization, irrigation, and the use of long juvenile soybean lines, on late-planted soybean yields has not yet been evaluated in the Southern Great Plains. The objectives of this study are to evaluate the effect of these specific management strategies on late-planted soybean yields and their potential adoption in the Southern Great Plains to minimize yield losses in these late production systems. Four different field studies were established on late plantings in Oklahoma as followed by numbers 1, 2, 3, and 4: 1) Four seeding rates ranging from 198,000 to 383,000 seeds ha-1, three row spacings (19, 38, and 76 cm) and two maturity groups (4.8 and 5.6) under rainfed conditions. Seed yield, plant population, canopy cover, and partial economic return were analyzed. Seed yield was not affected by seeding density, but yield results for 38 and 76 cm row spacings showed slight advantage to 19 cm rows. Partial economic return of 38 and 76 cm rows ranged from 13 to 25% greater than 19 cm row spacing, with the greatest returns at the lowest seeding densities. 2) Three soybean lines from maturity group (MG) 6, 7, and 8 carrying the long juvenile trait (LJ) were compared to three high-yielding varieties from MG 3, 4, and 5, in four planting dates from late-May to late-June. Vegetative growth period, canopy cover, seed yield, and seed quality were evaluated. Long juvenile soybean lines had greater growth but similar yields compared to non LJ varieties, due to the extended growth period overlapping early reproductive stages diminishing seed production potential. 3) Fertilization strategies including two starter and four foliar treatments were compared to a control treatment with no fertilizer applied. Starter or foliar treatments resulted in no seed yield differences compared to control treatment. 4) Soybean from MGs 4.8 and 5.6 were sown in 19 and 76 cm row spacings at three seeding rates (247,000, 346,000, and 445,000 seeds ha-1 were tested under irrigated conditions and seed yield evaluated. Seed yield of late-planted soybean under irrigation was affected only by MG. Seeding rate and row spacing had no effect on yield. Average yield of MG 4.8, across row spacings and years was 2620 kg ha−1, which was 25 % greater than MG 5.6 yield (1980 kg ha−1).

Download or read book Impact of Cereal Rye and Oat Cover Crop Planting and Termination Date on Disease Insects and Yield in Continuous Soybean Systems written by Keeley Overmyer and published by . This book was released on 2020 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the treated resistant soybean seed treatments, three out of four site-years, soybean stand was impacted by termination date of the cover crop. In the untreated susceptible soybean seed treatments, two out of four site-years, soybean stand was impacted by the termination date of the cover crop. Effects were varied based on weather. In two of four site-years, yield was impacted by cover crop termination date in treated resistant seed treatments, and yield was impacted by cover crop termination date in one of four-site years in the untreated susceptible seed treatments. Early terminated cover crop treatments resulted in significantly less yield. Improving soybean stand by planting cover crops early and adapting termination date based on soil moisture retention history may result in a higher yield.

Download or read book Short term Effects of Winter Cover Crops on Soil Properties Yield and Partial Returns in a No tillage Soybean Rotation written by Drew Dillion Kirkpatrick and published by . This book was released on 2021 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cover crops have the potential to provide many benefits including weed suppression, erosion control, and improvements to soil quality. These benefits can be affected by species, biomass accumulation, and management practices. Although large amounts of biomass are good for maximizing benefits, it can result in problems for establishing the subsequent crop. Soybean [Glycine max (L.) Merr.] accounts for over 50% of Arkansas crop hectares annually; therefore, understanding the effect that a cover crop can have on the following soybean crop is crucial to the successful implementation of cover crops within the state. A study was established to evaluate winter cover crops as an alternative to traditional Arkansas practices, such as winter fallow, as well as winter wheat (Triticum aestivum L.) soybean double-crop system, and the effect each cropping system has on soybean yield and partial returns. Additionally, a goal of this study was to assess a variety of cover crop species and blends as well as their effect on aboveground biomass accumulation, nutrient uptake, and stand establishment of the following soybean crop. Soil organic matter (SOM) and pH were also used to evaluate overall soil health following three full rotations of each winter treatment. Results of the study show that winter cover crops do not affect the following soybean crop establishment, but had a positive influence on soybean yield and partial returns in a no-tillage system. Except for blue lupin (Lupinus angustifolius), each cover crop treatment proved to be an equally viable alternative to a traditional double-crop system and more profitable than a winter fallow system. Cover crops not only have an immediate impact of increasing soybean yield, but cover crops also have the potential to provide long-term benefits. Previous research has shown that increased biomass production typically increases SOM and results of this study indicate that cover crop treatments produced up to four times as much aboveground biomass compared to a winter fallow management strategy. Treatments that produced the most biomass also accumulated the most aboveground nutrient contents for the macronutrients nitrogen (N), phosphorus (P), and potassium (K). There were no differences in soil health calculations, but each treatment received a "good" soil health score. Our results indicate that winter cover crops provide a promising alternative to the winter wheat soybean double-crop system and winter fallow management program and with continuous management, soil quality can be improved.
