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.

Available in PDF, EPUB and Kindle. Book excerpt: This publication consolidates information on the origin, descriptive characteristics, agronomic performance, seed composition, and disease reaction of over 2,000 soybean [Glycine max (L.) Merrill] germplasm accessions in maturity groups 000-IV from the USDA Soybean Germplasm Collection. These accessions were introduced into the United States by 1960. Publicly developed cultivars from the United States and Canada released by 1966 were also included. The data reported here were collected in three tests: maturity groups 000 to 0 at St. Paul, MN, in 1964; maturity groups I and II at Urbana, IL, in 1964, and maturity groups III and IV at Urbana, IL, in 1965 and 1966.
