Efficacy of pre and post emergence herbicides on yield and economics of linseed (Linum usitatissimum L.)

A field experiment was conducted at Agronomy Farm, College of Agriculture, Nagpur during rabi season 2022-23 to study the efficacy of pre and post emergence herbicides on yield and economics of linseed. The experiment was laid out in randomized block design (RBD) with eight treatments and three replications. Result revealed that among all the treatments weed free check treatment (T2) showed higher seed yield and highest B:C ratio. However, in the herbicidal treatments, application of PE Oxyflurofen @ 125 g a.i. ha-1 fb (Quizalofop 7.5% + Imazethapyr 15%) EC @ 32.81 g a.i. ha-1 + 65.625 g a.i. ha-1 at 25 DAS (T8) was found to be effective in higher number of capsules plant-1 (75.77), seed yield plant-1 (4.18 g), test weight (7.83 g), seed yield (1035 kg ha-1) and straw yield ( 2115 kg ha-1) of linseed which resulted in maximum net monetary returns (30340 Rs ha-1) and B:C ratio (2.24) which is at par with application of PE Metribuzin @ 250 g a.i. ha-1 fb (Quizalofop 7.5% + Imazethapyr 15%) EC @ 32.81 g a. i. ha-1 + 65.625 g a.i. ha-1 at 25 DAS (T5) with (28044 Rs ha-1) net monetary returns and 2.13 B: C ratio.
