Abstract:
Research work entitled “Effect of crop establishment and weed management practices on weeds, yield and economics of wheat (Triticum aestivum L.)” was carried out during two successive Rabi season of 2019-20 and 2020-21 at the Agricultural research farm of Institute of Agricultural sciences, Banaras Hindu University, Varanasi (UP). The experiment was conducted in split plot design replicated thrice with six crop establishment method as main plot treatment i.e. Zero till wheat + rice residue mulching (6 t ha^-1), Conventional till wheat + residue as mulch (6 t ha^-1), Zero till wheat - residue retention (30 cm height), Conventional till wheat - residue incorporation at 20 days before sowing (30 cm height rice residue), Zero till wheat – residue removed and Conventional till wheat-residue removed whereas weed management practices i.e. Weed free, Pendimethalin fb carfentrazone + iodosulfuron, Pendimethalin fb Sulfosulfuron + Metsulfuron and Weedy check. The data on various soil properties were recorded after harvest of wheat. Available NPK recorded significant differences; whereas no significant variation were observed in soil pH, EC and organic carbon but there were slightly increase due to various crop establishment methods and weed management practices.
