Book Synopsis Effect of Relative Maturity on Soybean Yield and Cover Crop Biomass Evaluation Methods by : Wayde Looker

This book was released on 2019 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ohio contains many acres of continuous soybean [Glycine max (L.) Merr.] production that may benefit from the incorporation of a fall-planted cover crop. Timely planting is extremely important when establishing a fall-planted cover crop. To ensure that cover crops are planted in a timely manner, soybean varieties with an earlier relative maturity may be planted so that soybeans are harvested earlier in the fall allowing for more timely cover crop planting. However, soybean relative maturity also impacts soybean grain yield, with earlier maturing varieties yielding less compared to later maturing varieties. The objectives of this study were to evaluate the relationship between relative maturity and grain yield, plant height, seed protein content, seed oil content and number of days to anthesis and physiological maturity. This study was completed during 2017 and 2018 at the Northwest Agricultural Research Station (NWARS) in Custar, Ohio, and the Western Agricultural Research Station (WARS) in South Charleston, Ohio. Grain yield, plant height, maturity date, and grain protein and oil concentration were measured. All measurements were taken just prior to or at harvest when grain was near 13% moisture content. Soybean yields plateaued at a 2.9 maturity at NWARS and 3.2 maturity at WARS. It was also determined that the earliest maturities reached the R8 growth stage approximately one month before the latest maturities (29.9 days at NWARS and 36.5 days at WARS) while the difference was about 10 days for R1 (8.7 days at NWARS and 12 days at WARS). Plant height held a linear relationship to relative maturity and increased as relative maturity increased. Seed protein content and seed oil content also held a linear relationship to relative maturity. Biomass accumulation is a useful way to measure the amount of vegetative growth produced by a cereal rye and oat cover crop. However, biomass measurements can be slow and labor intensive and a faster method may be available to estimate the accumulated biomass. The objective of this study was to evaluate the relationship between normalized difference vegetation index (NDVI), fractional green canopy cover (FGCC), and biomass of a cereal rye and oat cover crop. This study was conducted in 2017 and 2018 at WARS and NWARS using a split plot randomized complete block design with four replications of treatments. The main plot factor was four cover crop planting dates (late September to late October) and the sub-plot factor was two cover crop termination dates (late April and early May). Normalized difference vegetation index measurements, FGCC measurements, and biomass samples were collected in the fall and spring at each location. The results showed a quadratic relationship between both NDVI and FGCC to the biomass of the cereal rye and oat cover crop. However, the adjusted R2 value and the RMSE of the FGCC was greater, suggesting that the FGCC was a better indicator of biomass compared to NDVI.

Book Synopsis Identifying Optimal Management Decisions Based on Soybean Planting Date by : Thomas Bernard Siler
Download or read book Identifying Optimal Management Decisions Based on Soybean Planting Date written by Thomas Bernard Siler and published by . This book was released on 2020 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: The practice of early-season soybean [Glycine Max (L.) Merr.] planting has been increasing in the northern US. However, a wide range of planting dates (PDs) are still implemented due to poor soil conditions, inclement weather, equipment restrictions, crop rotation, and operation size. Information regarding how soybean management decisions should be adjusted based on PD is lacking in Michigan and other northern US regions. This research was conducted to identify how optimal soybean seeding rate (SR), seed treatment (ST) use, and variety maturity group (MG) selection is determined by PD. Field experiments were conducted at two locations in Michigan during the 2018 and 2019 growing season. In the first experiment, soybean was planted at five SRs, between 123,553 and 518,921 seeds ha−1, with or without a ST, on four PDs (late-April to late-June). In the second experiment, six soybean MGs, between 1.0 and 3.5, were planted on four PDs (late-April to late-June). The use of a ST did not improve yield or net returns in this study. When soybean was planted before mid-May, seed yield and net returns were maximized by planting a late MG (≥ 3.0) at a SR between 187,660 and 201,451 seeds ha−1. The optimal SR between the mid-May and early-June PDs was between 220,301 and 265,305 seeds ha−1 and MG selection had less influence on seed yield compared to earlier PDs. When planting was delayed to late-June, using an early MG (≤ 2.5) resulted in the optimal yield and the optimal SR was > 330,000. Results from this study show that soybean yield, quality, and net returns can be improved by adjusting management practices based on PD.

Book Synopsis Managing Cover Crops Profitably (3rd Ed. ) by : Andy Clark
Download or read book Managing Cover Crops Profitably (3rd Ed. ) written by Andy Clark and published by DIANE Publishing. This book was released on 2008-07 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cover crops slow erosion, improve soil, smother weeds, enhance nutrient and moisture availability, help control many pests and bring a host of other benefits to your farm. At the same time, they can reduce costs, increase profits and even create new sources of income. You¿ll reap dividends on your cover crop investments for years, since their benefits accumulate over the long term. This book will help you find which ones are right for you. Captures farmer and other research results from the past ten years. The authors verified the info. from the 2nd ed., added new results and updated farmer profiles and research data, and added 2 chap. Includes maps and charts, detailed narratives about individual cover crop species, and chap. about aspects of cover cropping.

Book Synopsis Advances in Biology and Ecology of Nitrogen Fixation by : Takuji Ohyama
Download or read book Advances in Biology and Ecology of Nitrogen Fixation written by Takuji Ohyama and published by BoD – Books on Demand. This book was released on 2014-01-29 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological nitrogen fixation has essential role in N cycle in global ecosystem. Several types of nitrogen fixing bacteria are recognized: the free-living bacteria in soil or water; symbiotic bacteria making root nodules in legumes or non-legumes; associative nitrogen fixing bacteria that resides outside the plant roots and provides fixed nitrogen to the plants; endophytic nitrogen fixing bacteria living in the roots, stems and leaves of plants. In this book there are 11 chapters related to biological nitrogen fixation, regulation of legume-rhizobium symbiosis, and agriculture and ecology of biological nitrogen fixation, including new models for autoregulation of nodulation in legumes, endophytic nitrogen fixation in sugarcane or forest trees, etc. Hopefully, this book will contribute to biological, ecological, and agricultural sciences.
