Assessment of Weed Management Practices in Linseed (Linum usitatissimum L.)

Abstract

A field experiment was carried out during rabi 2024 on loamy sand soil of Agronomy Instructional Farm, C. P. College of Agriculture, Sardarkrushinagar Dantiwada Agricultural University, Sardarkrushinagar to find out the most effective weed management practices in linseed. The experiment was laid out in RBD with four replications having eight different weed management practices. The result revealed that weed free treatment recorded significantly higher seed and stover yield (1588 and 2408 kg/ha, respectively) and found at par with pendimethalin @ 750 g/ha as PE fb one interculturing at 30 DAS and one HW at 45 DAS (1407 and 2272 kg/ha, respectively), two HW at 30 and 45 DAS (1382 and 2235 kg/ha, respectively), pendimethalin @ 750 g/ha as PE fb clodinafop + metsulfuron methyl @ 64 g/ha as PoE (1379 and 2160 kg/ha, respectively),  pendimethalin @ 750 g/ha as PE fb metsulfuron methyl @ 4 g/ha as PoE (1312 and 2042 kg/ha, respectively) as compared to weedy check (902 and 1566 kg/ha, respectively) due to suppression of weeds at 60 DAS and at harvest with higher weed control efficiency and lower weed index values. Moreover, pendimethalin @ 750 g/ha as PE fb clodinafop + metsulfuron methyl @ 64 g/ha as PoE recorded higher net returns (₹43797/ha) and B:C ratio (2.06) as compared to weedy check.
