Different sowing dates affected cotton yield and yield components
This study was conducted to determine whether selecting an optimum sowing date couldimprove yield. The experiment consisted of sowing a film-covered, drip-irrigated cotton field onfour sowing dates from April to May in 2011-2012 at the Agrometeorological ExperimentalStation of Wulanwusu, which was in an arid region of north-western China. Late sowing datesproduced less yield and water-use effic...

15 صفحه اولEffects of relay-intercropping sorghum with winter wheat, alfalfa, and cotton on lady beetle (Coleoptera: Coccinellidae) abundance and species composition.
Creating conditions that enhance the abundance of resident populations of natural enemies in agroecosystems is considered critical to the efficiency of biological control of insect pests. We conducted a study to determine the potential of relay-intercropping for enhancing the abundance of aphidophagous lady beetles in sorghum. A relay-intercropping system consisting of alfalfa, winter wheat, an...
متن کاملthe effect of seed priming on emergence and yield of cotton at different sowing dates
priming is one of the seed enhancement methods that might be resulted in increased seed performance (germination and emergence). the objective of this research was to evaluate effect of priming on seed emergence and yield under wide ranges sowing dates in cotton. treatments were combinations of 6 sowing dates and 2 seed treatments (control and primed seeds). hydropriming method was used; seeds ...
