Residual studies of herbicides and nutrient management in wheat following an application to soybean

Abstract

An experiment was conducted at Rajasthan College of Agriculture, Maharana Pratap University of Agriculture & Thechnology- Udaipur during the year of 2015-16 and 2016-17. Residual effect of herbicides and nutrient which were used in previous soybean crop with recommended dose of fertilizers to wheat did not influenced significantly in weed control as well as growth attributes, viz. plant height, plant dry matter and effective tillers/meter row length in wheat. Seed and straw yields, net monetary return and return/rupee invested were obtained higher under residual effect of propaquizafop + imazethapyr (75 +75 g ha-1) at 21 DAS with NPKS (20:40:30:40 kg ha-1). Similarly, nutrient uptake in terms of N, P and K were also found greatest under this treatment combination. However, overall residual impact was found non significant during both the year.
