Abstract:
A field experiment was conducted with the aim to know weed management effects on weed density, growth parameters, yield and yield attributes of transplanted rice in Typic ustochrept soil during Kharif 2016 at Crop Research Centre of Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut, U. P. (India). The experimental site was sandy loam in texture, low in organic carbon and available N, medium in available P and K and slighty alkaline in reaction. The experiment was set in randomized complete block design with three replications comprising twelve weed management treatments. Among the different herbicidal treatments lowest density of total weeds was found with the application of Pyrazosulfuron fb Bispyribac Sodium (150 g a.i ha-1 PE fb 25g a.i ha-1 POE) and found at par with Pyrazosulfuron fb Azimsulfuron (150 g a.i ha-1 PE fb 30 g a.i ha-1 POE). The results indicated that the highest plant height, number of tillers (m-2), dry matter accumulation, leaf area index, protein content, 1000-grain weight, and biological yield (116.5 q ha-1) were recorded with the application of Pyrazosulfuron fb Bispyribac Sodium (150 g a.i ha-1 PE fb 25g a.i ha-1 POE) followed by Pyrazosulfuron fb Azimsulfuron (150 g a.i ha-1 PE fb 30 g a.i ha-1 POE) treatments. Grain and biological yield of rice was registered 37.66 and 34.93 per cent higher under Pyrazosulfuron fb Bispyribac Sodium (150 g a.i ha-1PE fb 25g a.i ha-1 POE) treatment in comparison to weedy check treatment, respectively. This shows that Pyrazosulfuron fb Bispyribac Sodium (150 g a.i ha-1PE fb 25g a.i ha-1 POE) can be applied in transplanted rice for effective weed control, higher growth and productivity.
