Effect of herbicides on weed growth parameter and stover yield of linseed (<em>Linum usitatissimum</em> L.)

Abstract

A field experiment was conducted at Research cum Instructional Farm of Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh during Rabi season of 2016-17 an entitled effect of herbicides on weed growth parameter and stover yield of linseed (Linum usitatissimum L.). The experiment was laid out in randomized block design (RBD) with ten treatments. Results revealed that different herbicides significantly affected on maximum number of secondary branches plant-1 at 60, 90 DAS, at harvest, highest leaf area index at 30, 60, 90 DAS and stover yield were recorded under the hand weeding twice 21 and 45 DAS, which was statistically at par with metsulfuron-methyl (4 g ha-1) PoE, isoproturon (1 kg ha-1) PoE, isoproturon + metsulfuron-methyl (1 kg + 4 g ha-1) PoE and pendimethalin (1 kg ha-1) PE fb metsulfuron-methyl (4 g ha-1) PoE. The lowest number of secondary branches, leaf area index and stover yield were observed under treatment of weedy check.
