Effect of nutrient management and weed control practices on growth parameters of wheat (Triticum aestivum L.)

Abstract

An experiment was carried out at Agronomy Research Farm of Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya (Uttar Pradesh) in two consecutive years (2022-23 & 2023-24) in Rabi season to find out the effect of nutrient management and weed control practices on growth parameters of various treatments on wheat crop. The experiment was laid out in split plot design with three nutrient levels and six weed control practices and replicated thrice. Application of 75% RDF + 10 t ha-1 FYM + one spray of nano-urea @ 4 ml/lit noted greater effect on plant height, number of tiller, leaf area index and dry matter accumulation during both years of experimentation. In case of weed management, spray of Clodinofop + Metsulfuron (60 + 4 g a.i. ha-1) found more effective to increase the growth of wheat during both year of investigation. This treatment having better weed control and higher nutrient uptake resulted in higher growth. It can be concluded that application of 75% RDF +10 t ha-1 FYM + one spray of nano-urea @ 4 ml/lit with the spraying of Clodinofop + Metsulfuron (60 + 4 g a.i. ha-1) proved better to increase the growth of wheat crop.
