Compatibility of sulfosulfuron and metsulfuron-methyl for the control of complex weed Phalaris minor in wheat through frontline demonstrations of eastern Uttar Pradesh

Abstract

Front Line Demonstration is one of the most powerful tools for transfer of technology. The present study was undertaken to find out the yield gap through FLDs on wheat crop. Krishi Vigyan Kendra, Maharajganj, Eastern U.P. conducted 75 front line demonstration on wheat crop at farmers field of fifteen adopted villages during 2018-19 and 2019-20 for transfer of technology. In two consecutive year demonstration programme of improved wheat production technology on wheat variety HD 2967 demonstrate production potential and economic benefit of improved technologies consisting herbicidal management. Application of Sulfosulfuron + Metsulfuron 32 g/ha resulted in significantly lower plant population of Phalaris minor followed by effect of Isoproturon + 2,4-D (1000 + 500 g/ha) application resulted in more number of P. minor. Grain yield were significantly higher in treated plots as compared to the control Sulfosulfuron + Metsulfuron 32 g/ha gave maximum grain yield 36.05q/ha compared to control 22.85q/ha, which could possibly use for herbicides control in wheat crop with a considerable higher yield. The extension gap and technology gap were observed to be 13.20 q/ha, 13.95 q/ha respectively. The technology index (%) of 27.90%. Technology index was recorded to be decreased over the successive years of study the successive decreased value of technology index reflected the feasibility of the demonstrated technology in agro - climatic condition of eastern Uttar Pradesh.
