Abstract:

An field experiment was conducted during kharif season of 2017 and Rabi season of 2018 to study the effect of crop establishment methods viz., System of Rice intensification, Machine planting, Conventional method of transplanting and weed control practices ay application of pre emergence herbicide (Metsulfuron Methyl 10 % - Chlorimuron Ethyl 10 % )10 and 20 g ha-1 and, Butachlor10 g ha-1 and 2.5 lit per ha-1 + three mechanized weeding at 25,35,45 DAT ,hand weeding on 20 DAT, four mechanized weeding at 15,25,35,45 DAT and hand weeding twice at 20 and 40 DAT. The experiment was laid out in split plot design with a main plot of three planting methods and seven weed control practices as sub plots and were replicated twice. SRI rice registered significantly higher grain and straw yield and it was comparable with other planting methods during both the years. The lowest grain yield was observed at conventional method of planting. Among the weed management practices, SRI planting methods +pre emergence application of (Metsulfuron Methyl 10 % - Chlorimuron Ethyl 10 %) 20 g ha-1 cono weeding thrice registered lower weed density and dry weight which resulted in significantly higher grain yield and it was comparable with application of Butachlor 2.5 lit per ha-1 + three mechanized weeding. The density of weeds as well as dry weight was higher in conventional method of planting. The highest weed control efficiency was recorded in SRI method of planting and pre emergence application of (Metsulfuron Methyl 10 % - Chlorimuron Ethyl 10 % )@ 20 g ha-1 .
