Impact of early season insect management decisions on yield of soybean

North, John Hartley 09 August 2019 (has links)
To determine the optimal seeding rate and utilization of seed treatment combinations for maximizing soybean yield within optimal and late planting dates. Also, experiments were conducted to quantify effects of soybean stand loss and to determine optimal seeding rates at various planting dates comparing three seed treatments. Experiments were conducted to test influence of planter type and seeding rate on soybean. Soybean seed treated with at planting insecticides showed no difference in yield compared to fungicide only treated seed. Also, yields were maximized at low seeding rates where no stand loss occurred. Soybean yields benefited from where seeding rates were increased at 20% and 40% stand loss. Higher seeding rates can provide significant risk of yield and economic losses if no stand loss occurs. Optimal plantings can significantly increase soybean yields compared to later plantings. There was a significant difference in yield where fungicide only treated seed was planted compared to seed treated with a neonicotinoid. Low seeding rates maximized yield at optimal planting dates but were penalized at late planting dates. Soybean yields benefited from increased seeding rates at the later planting dates but there was no difference in any of the seed treatments compared to untreated soybean. Also, there was less variation in inter-spacing of plants at the lower seeding rate compared to higher seeding rate when using the cone planter compared to the other planter types. There was no difference in yield for soybean planted with any of the evaluated planter types. Yield differences were observed from higher seeding rate compared to low seeding rate.

Evaluation of soybean performance following multiple exposures to sub-lethal rates of dicamba

Corban, Nelson 09 August 2019 (has links)
In 2017, dicamba formulations were labeled for PRE and POST applications and utilized in soybean to control herbicide-resistant weed species. Dicamba-tolerant soybean cultivars were grown in proximity to those representing other herbicide-resistant technologies, creating the potential for problems with off-target movement. Field studies conducted in 2017 and 2018 in Stoneville, MS, characterized the soybean response to exposure to sub-lethal rates of different dicamba formulations and evaluated the performance of soybean cultivars representing different soybean maturity groups following multiple exposures to a sub-lethal rate of dicamba. Other field experiments in 2018 evaluated the performance of soybean following a single exposure to sub-lethal rates of dicamba at different growth stages (Rate and Timing Study) and characterized soybean response to multiple exposures of a sub-lethal rate of dicamba at different growth stages (Multiple Exposures Study).
