Effect of fertility levels and weed management practices on yield and economics of wheat crop (Triticum aestivum L.)

Abstract

The field experiment was conducted during the rabi season of 2018–19 and 2019–20 at Agronomy Research Farm of Acharya Narendra Deva University of Agriculture & Technology, Narendra Nagar (Kumarganj), Ayodhya, U.P. with two factor, 3 fertility levels (100% DRF through inorganic fertilizer, 75% RDF through inorganic + 25% N through FYM and 50% RDF through inorganic + 50% N through FYM) and 5 weed control practices (Sulfosulfuron + Metsulfuron @ 30 g a.i. + 4 g a.i. ha-1, Clodinafop + Metsulfuron @ 60 g a.i. + 4 g a.i. ha-1, Mesosulfuron + Iodosulfuron @ 12.2 g a.i + 2.2 g a.i. ha-1, weed free upto 60 Days and Weedy check. The treatments were replicated three times in a factorial randomized block design with fifteen treatment combinations. Among the treatment combinations 100% RDF (NPK- 150:60:40) with weed free upto 60 days was recorded maximum value of grain yield, straw yield, biological yield, gross returns and net returns during both the years. Higher benefit cost ratio was recorded with the treatment combinations of 100% RDF and Sulfosulfuron + Metsulfuron @ 30 g a.i. + 4 g a.i. ha-1. Thus, it may be concluded that application of 100% recommended dose of NPK ha−1 with Sulfosulfuron + Metsulfuron @ 30 g a.i. + 4 g a.i. ha-1 as proved most superior to other treatment in respect to higher benefit cast ratio of wheat crop.
