Cultural management practices that reduce the off-site transport of herbicides applied to row crops are needed to protect surface water quality. A soybean [Glycine max (L.) Merr.] field study was conducted near Stoneville, MS on Sharkey clay to evaluate row spacing (50 cm vs. 100 cm) effects on metolachlor [2-chloro-N-(2-ethyl-6-methylphenyl)-N-(methoxy-1-methylethyl) acetamide] transport. One ...

In this research effects of active toothed coulter on planter penetration in semi-dried soils covered with previous wheat (Triticum aestivum) residue was studied. Therefore, effects of three levels of speed ratio (coulter peripheral speed/tractor forward speed; 1.22, 2, 3) at two previous residue levels (baled and non-baled) and two modes of planter attachment (with and without row cleaner) on ...

To evaluate fall dormancy of twenty alfalfa local ecotypes and exotic cultivars, this study was conducted in two separate experiments (conventional or dense planting and spaced planting) using randomized complete block design with three replications in three growing seasons 2014, 2015 and 2016 in two locations (Karaj and Khoy), Iran. First growing season was considered as estabilishment season....

Knowledge of the effects of row spacings and seeding rates on dual-purpose forage and seed production of an annual legume crop is essential for its proper agronomical exploitation. In this study, the effects of various row spacings and seeding rates on dry matter and seed yield in berseem clover (Trifolium alexandrinum L.) were evaluated in two consecutive years. The experimental design was a s...
