Soybean Sowing Date: The Vegetative, Reproductive, and Agronomic Impacts
The sensitivity of soybean [Glycine max (L.) Merr.] main stem node accrual to ambient temperature has been documented in greenhousegrown plants but not with fi eld-grown plants in the north-central United States. Biweekly V-node and R-stage, stem node number, internode length, and other traits were quantifi ed in an irrigated split-plot, four-replicate, randomized complete block experiment cond...
متن کاملUsing simulation models to investigate the cumulative effects of sowing rate, sowing date and cultivar choice on weed competition
With the increasing pressure on crop production from the evolution of herbicide resistance, farmers are increasingly adopting Integrated Weed Management (IWM) strategies to augment their weed control. These include measures to increase the competitiveness of the crop canopy such as increased sowing rate and the use of more competitive cultivars. While there are data on the relative impact of th...
متن کاملPlanting Date and Soybean Cultivar Maturity Group Affect Population Dynamics of Heterodera glycines, and All Affect Yield of Soybean.
Five soybean cultivars, one each from Maturity Groups (MG) III, IV, V, VI, and VII, all susceptible to Heterodera glycines, were planted in H. glycines-infested soil in April, May, June, and July at multiple locations in Arkansas and Missouri. The purpose of the study was to determine whether planting early reduces yield losses due to H. glycines. The population levels of cysts, eggs, and secon...
متن کاملFoliar Fungicides for Control of Diseases on Pumpkins, 2001
Pumpkins for Halloween usage have become a widely grown crop in Tennessee. This season four fungicide treatments were evaluated for efficacy at The University of Tennessee Plateau Experiment Station at Crossville in 2001. Foliar diseases require a strict spray schedule for effective control. Therefore, a well balanced Integrated Pest Management program for control of mildew and blight diseases ...
متن کاملProjected Crop Production under Regional Climate Change Using Scenario Data and Modeling: Sensitivity to Chosen Sowing Date and Cultivar
A sensitivity analysis of the responses of crops to the chosen production adaptation options under regional climate change was conducted in this study. Projections of winter wheat production for different sowing dates and cultivars were estimated for a major economic and agricultural province of China from 2021 to 2080 using the World Food Study model (WOFOST) under representative concentration...
