Domesticated soybean [Glycine max (L.) Merr.] is a major crop with an established ancestral relationship to wild soybean (Glycine soja Sieb. & Zucc.) native to Asia. Soybean genetic diversity can be assessed at different levels by identification of polymorphic alleles at genetic loci, in either the plastid or nuclear genomes. The objective of this study was to evaluate genetic diversity based o...

Most dairy farms in Wisconsin continue to follow a fairly generalized formula of how to produce milk. Cows and replacement heifers are fed primarily homegrown feed from crop rotations comprising alfalfa (Medicago sativa L.), corn (Zea mays L.), oats (Avena spp.) and soybean (Glycine max L. Merr.). Protein and mineral supplements are purchased to compliment dairy diets. However, the dairy indust...

Soybean [Glycine max (L.) Merr.] yield has increased over time through the introduction of new varieties and improved agronomic practices. However, seed protein concentration decreased. We conducted field studies in 2018 2019 to investigate effects fungicide, insecticide, foliar fertilizer application on grain quality two soybean maturity groups (MG). In-season treatments targeted nutrient avai...

Prospects for utilizing whole-genome association analysis in autogamous plant populations appear promising due to the reported high levels of linkage disequilibrium (LD). To determine the optimal strategies for implementing association analysis in soybean (Glycine max L. Merr.), we analyzed the structure of LD in three regions of the genome varying in length from 336 to 574 kb. This analysis wa...

The experiments were conducted at Green Acres Agronomy farm near Gainesville, Florida, on an Arredondo loamy sand, a member of the loamy, silicious, hyperthermic family of grossarenic Paleudults. The field study started in 1976 included cropping systems of oat (Avena sativa)/soybean (Glycine max L. Merr.) versus oat/grain sorghum (Sorghum bicolor L.) that were split plots of four tillage treatm...

Poultry litter is a nutrient-dense fertilizer, but surface applications lead to nutrient losses air, soil, and water. Objectives were evaluate optimum subsurface-applied poultry bands from crop seeding distance in corn (Zea Mays L.)–soybean [Glycine max (L.) Merr.] rotation. Soil amendment treatments included planting 13, 25, 38 cm subsurface-banded litter, surface-applied inorganic nitrogen (N...

The aim of this study was to evaluate the response corn (Zea mays L.) grain yield nitrogen (N) fertilizer application and its residual effect on soybean (Glycine max (L.) Merr.) seed yield. During 2020 growing season, a corn-soybean rotation continued at Scandia, KS (USA), evaluating five N rates in under both dryland irrigated conditions. Average yields ranged from 110 206 bu/a for dryland, 19...

A procedure was developed for the partial purification of succinate dehydrogenase from mung bean (Vigna radiata L.) hypocotyls and soybean (Glycine max [L] Merr. v. Ransom) cotyledons. The procedure utilized a Triton X-100 extraction followed by ammonium sulfate precipitation. The final fraction was enriched in two polypeptides with approximate molecular weights of 67,000 and 30,000 daltons, ex...

objective: the aim of this study was to estimate genetic variability and phonetic relationships of 50 isolates of p. sojae from iran. methods: during 2005–2007, 142 isolates of phytophthora sojae were collected from soil samples and diseased soybean plants from lorestan, mazandaran, golestan and ardabil provinces. races of the isolates were determined. dna of p. sojae fifty isolates was amplifi...
