Cover Crops, Drought, Yield and Risk

Languages : en
Pages : 0
Book Description
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.

Interseeding of Cover Crop Species Into Soybean
Increasing Yield of Late-planted Soybean Through Management Practices in the Southern Great Plains

Languages : en
Pages : 117
Book Description
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).

Soil Management
Author: Jerry L. Hatfield
Publisher: John Wiley & Sons
ISBN: 0891188533
Category : Technology & Engineering
Languages : en
Pages : 432
Book Description
Degradation of soils continues at a pace that will eventually create a local, regional, or even global crisis when diminished soil resources collide with increasing climate variation. It's not too late to restore our soils to a more productive state by rediscovering the value of soil management, building on our well-established and ever-expanding scientific understanding of soils. Soil management concepts have been in place since the cultivation of crops, but we need to rediscover the principles that are linked together in effective soil management. This book is unique because of its treatment of soil management based on principles—the physical, chemical, and biological processes and how together they form the foundation for soil management processes that range from tillage to nutrient management. Whether new to soil science or needing a concise reference, readers will benefit from this book's ability to integrate the science of soils with management issues and long-term conservation efforts.

Impact of Cereal Rye and Oat Cover Crop Planting and Termination Date on Disease, Insects, and Yield in Continuous Soybean Systems

Category : Cover crops

Book Description
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.
