tailieunhanh - Response of different weed management practices on yield, quality and nutrient uptake of Kharif drilled rice (Oryza sativa L.)

Field experiment was conducted at Agronomy farm of Dr. . Konkan Krishi Vidyapeeth, Dapoli during kharif season of 2014 to study the effect of different weed management practices on yield, quality and nutrient uptake of kharif rice (Oryza sativa L.). The experiment was laid out in a randomized block design. There were ten treatments which were replicated thrice. The treatments mainly comprised of Bispyribac-Na PoE (T1), Pendimethalin PE fb Bispyribac-Na PoE (T2), Oxadiargyl PE fb Bispyribac-Na PoE (T3), Pyrazosulfuron PE fb Bispyribac-Na PoE (T4), Pendimethalin PE fb Bispyribac-Na PoE fb Manual weeding (T5), Pendimethalin PE fb Manual weeding (T6), Bispyribac-Na + (Chlorimuron + Metasulfuron) PoE (T7), Three mechanical weedings (cono/rotary weeder at 20, 40 and 60 DAS) (T8), Weed free check (Hand weeding at 20, 40 and 60 DAS) (T9) and Weedy check (T10). Results revealed that treatments Weed free check, Pendimethalin PE fb Manual weeding and Pendimethalin PE fb Bispyribac-Na PoE fb. Manual weeding produced higher growth and yield attributes as compared to rest of the treatments under study. Treatment weed free check recorded highest grain and straw yield of rice. | Response of different weed management practices on yield quality and nutrient uptake of Kharif drilled rice Oryza sativa L.
