Management of Orobanche in Mustard

Abstract

An experiment was conducted during rabi season in 2017-18, 2019-20 and 2021-22 (three years) at Agronomy Instructional Farm, Chimanbhai Patel College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar, Gujarat, India having loamy sand soil to study the management of Orobanche in mustard. The experiment was laid out in a randomized block design and four replications with nine treatments. On three years pooled results rewarded that for securing higher yield and net return keeping mustard crop weed-free (removal of all weeds including Orobanche) but under laborer scarce situation, advised to carry out a directed spray of glyphosate 25 g active ingredient/ha at 25-30 DAS and 50 g a.i./ha at 50-55 DAS on Orobanche. Further, weed-free (Removal of all weeds including Orobanche) also significantly increased seed yield (1809 kg/ha) while maximum net realization and benifit: cost ratio (BCR) was registered with the application of glyphosate @ 25 g a.i./ha at 25-30 DAS and 50 g/ha @ 50-55 DAS followed by treatment weed free (Removal of all weeds including Orobanche) in pooled results.
