Soybean Growth and Yield Response to Seeding Rate in Virginia
Soybean [Glycine max (L.) Merr.] seed cost has increased dramatically with the introduction and adoption of herbicide-resistant cultivars, generating interest from growers to reduce seeding rates to the lowest possible level that does not affect yield. Research indicates that greater seeding rates …

Ecology of Root Nodule Bacterial Diversity: Implications for Soybean Growth
Diazotrophs supply legumes such as soybean (Glycine max L. Merr) with nitrogen (N) needed for protein synthesis through biological nitrogen fixation (BNF). Through BNF, these bacteria such as Bradyrhizobium that reside in soybean root nodules, convert atmospheric nitrogen (N2) into ammonia (NH3/ …

Pseudomonas spp. Isolated from Soybean Nodules Promote Soybean Growth and Nitrogen Fixation
Nitrogen-fixing bacteria in soybean nodules convert atmospheric nitrogen to plant-available forms in exchange for carbon from the plant, but other non-nitrogen-fixing bacteria also reside in nodules, and their role in the nodule is not well understood. This study was conducted to determine the …

Beneficial Fungal Secretome and Synthetic Consortia to Improve Soybean Growth During Drought Stress
… synthetic community (FunSynCom) to improve growth and drought resilience in soybeans. In this study, we isolated, identified, and characterized a set of fungal endophytes from the rhizosphere of halophytic plants during a low-tide summer with reduced soil moisture levels. Fungal strains were …

Effect of Liquid Manure on Corn and Soybean Growth, Nitrogen Uptake, and Yields
… potassium (K) for corn, has resulted in uneven growth and reduced grain yields. Field studies were conducted at Pearl City, Illinois, in 1983 and 1984 to evaluate the effects of manure rate, nitrification inhibitors, methods of manure application, and supplemental inorganic N on corn and soybean …

Soybean growth and yield response to interplant competition relief in various plant density environments
Soybeans have the ability to regulate growth and yield component production in response to changes in plant population and competition. Previous research has addressed these issues from various aspects, however, there is a lack of information regarding how interplant competition affects plant size …

Pseudomonas spp. Isolated from the Soybean Nodule Interior Promote Soybean Growth upon Field Amendment
Diazotrophic microbes reside in soybean nodules; however, other non-nitrogen fixing bacteria are a part of the interior nodule microbiome. Results from a previous greenhouse study show that a novel species of Pseudomonas associates with soybean nodules as a plant-growth promoting rhizobacteria …

Physiological studies and modeling of photoperiodic effects on flowering and maturity in soybeans (Glycine max (L.) Merr.) differing in maturity
Soybean (Glycine max (L.) Merr.) is one of the most important economic crops in the United States, especially in the midwest area such as Illinois. This thesis research involved studies of photoperiod effects on soybean growth and development especially focused on flowering in relating to …

Analysis of the Effect of Two Tillage Systems on Soybean (Glycine Max (L.) Merrill) Growth
… well structured soils of the Corn Belt, soybean yield is not substantially affected by tillage. Available reports of differences are in the minority. There is relatively little information as to what extent and under what conditions the tillage methods affect the growth of soybean in the …

Nitrogen and Sulfur Management in Soybean and Edamame Production in the Mid-Atlantic Coastal Plain
The United States is a world leader of soybean [Glycine max (L.) Merr.] production, but to maintain quality production at this level, soybean management needs to be continually monitored and improved. Sulfur (S) deficiencies in soybean have become more frequent in the U.S. due to fertilizer purity, …

Effects of Simulated Acid Rain on Growth and Yield of Field-Grown Corn and Soybeans (Glycine Max, Zea Mays)
… determine the effects of acid rain on corn and soybean growth and production. Two corn (Zea mays L.) and two soybean (Glycine max L.) cultivars were exposed to six simulated rain acidity levels throughout the 1983 and 1984 growing seasons. The field experiments were conducted on a Flanagan silt …

The use of fertilizer nitrogen applications to increase productivity of soybean
For optimal productivity, soybean [Glycine max (L.) Merr.] may require fertilizer nitrogen (N) to supplement biological N fixation. The objective of this study was to identify the best fertilizer source and the best plant growth stage for N applications to increase soybean yield using N …

Soybean transpiration, vegetative morphology, and yield components following simulated and actual insect defoliation
<p>Soybean response to simulated green cloverworm (Plathypena scabra (F.)) (GCW) defoliation was investigated in several experiments from 1980 to 1983. The primary goals of this research were: (1) to assess the fidelity of simulation methods to actual insect defoliation for one basic physiological …
