Planting winter-annual cover crops prevent soil erosion, reduces water runoff, and improves soil structure and soil quality. This research was conducted from 2017 to 2019 to evaluate the nutrient turnover of different species of cover crops in soils under different row crop production systems in Northeast and Central Louisiana. In Northeast Louisiana (Site 1, 2, and 3), treatments (cover crops and no cover crop) were arranged in a strip trial with three replications. At the Ben Hur Research Station, the treatments included three planting dates (September, October, and November) with [7 kg ha-1 of phosphorus (P) and potassium (K)] …

LSU Master's Theses
The importance of leaf area to corn for grain production beginning at silking is well documented. However, being able to predict yield loss due to defoliators such as foliar plant diseases and insects that progressively increase in defoliation over time has been difficult to quantify. To address this issue, a leaf removal study was conducted at the Dean Lee Research and Extension Center located near Alexandria, Louisiana in 2017 and 2018. Two hybrids, differing in relative maturity were evaluated in this study. An early maturing hybrid (108 days in 2017 and 107 days in 2018) and a later maturing hybrid …
