Soybean Planting and Risk-Return Tradeoffs in the Mid-Southern United States
… the effects of soybean (Glycine max (L.) Merr.) planting date (PD) and maturity group (MG) selection on producer expected returns. Having to replant soybean after early-season planting because of poor stand establishment is costly for producers. Replanting costs have increased in the last ten …

Determination and Manipulation of Leaf Area Index to Facilitate Site-Specific Management of Double-Crop Soybean in the Mid-Atlantic, U.S.A.
… management strategies such as varying plant population may be used to manipulate LAI and increase yield in leaf area-limited systems. Furthermore, methods to remotely sense leaf area are in order to facilitate such management strategies in large fields. The objectives of this research …

Phenotypic plasticity in soybeans (glycine max (l.) merrill) associated with plant density and phenological stage at thinning
… when exposed to either supra or sub optimal plant density stress. However, it is not known whether determinate and indeterminate varieties respond the same and at what phenological stage a soybean plant is able to exhibit adaptive plasticity or elasticity response after thinning. The …

Industrial hemp agronomic management for grain, fiber, and forage
… and EcoFibre (bred specifically for fiber), were planted into seedbeds prepared with conventional tillage and no-till management. The cultivar Joey, lower plant populations under seed production systems resulted in taller plants (P = 0.0002) compared to the dual-purpose production systems in 2020. …

Canopy Architecture and Plant Density Effect in Short-Season Chickpea (Cicer arietinum L.)
… moisture. The current recommended chickpea population density of 44 plants m-2 is based on preliminary studies and a narrow range of 20 to 50 plants m-2. The aims of this study were to i) determine optimum population density of varying chickpea canopy types, i.e., leaf type and growth habit, …

Mathematical Models of <i>Zea mays</i>: Grain Yield and Aboveground Biomass Applied to Ear Flex and within Row Spacing Variability
… spacing within rows on Zea mays L. yield. Plant spacing other than uniform decreases grain yield and profitability. The population experiments conducted at the Warren County location were a randomized complete block design with three planting densities, three varieties (c.v. DeKalb DKC6547, …
