Abstract:
A field experiment entitled “Effect of weed management practices on growth and yield of direct seeded rice (Oryza sativa L.)” was conducted at Agronomy Research Farm of Narendra Deva University of Agriculture and Technology, Kumarganj, Faizabad (U.P.) during kharif season of 2015-16 and 2016-17. The experiment was laidout in randomize block design with twelve treatments consist in three replications. Result revealed that application of Pendimethaline fb Bispyribac-Na @ 1000 fb 25 g a.i. ha-1 + HW 40 DAS was recorded significantly least density of difference weed flora and dry weight of weed as compare to weedy check. Maximum values (81.97 and 84.50%) of WCE was found with application of Pendimethaline fb Bispyribac-Na @ 1000 fb 25 g a.i. ha-1 + HW 40 DAS, however, weed index values (1.82 and 3.88%) calculated minimum during both the years. All the growth and yield plant height, dry matter, LAI, as well as grain and straw yield were significantly higher in Significantly higher and lower values of yield attributes and yield, as well as lower and higher values of density and dry matter of weeds were recorded with weed free and weedy treatment, respectively.
