Abstract: The field experiments were conducted during Kharif season of 2015, 2016, and 2017 at Gaja Research and Extension Centre, College of Forestry, V.C.S.G. Uttarakhand University of Horticulture and Forestry, Ranichauri, Uttarakhand, India to find out effective establishment and weed management method for the maximizing the productivity of barnyard millet crop. Four establishment methods and four weed management practices were tested in split plot design with three replications. Major weeds found in the plots were Galinsoga parviflora, Persicaria capitatum, Paspalum dilatatum, Digitaria ciliaris, Oxalis latifolia, Setaria glauca Cyperus defformis and Cyperus iria. Among the establishment methods higher seed rate of 15 kg per hectare recorded significantly lower density and biomass of weeds in turn resulted in higher grain and straw yield of barnyard millet. Among the weed management treatments one inter-culture at 20 DAS and one hand weeding at 40 DAS registered significantly higher grain yield than pre-emergence spray of isoproturon 0.5 kg a.i./ha+ one inter-culture at 40 DAS, the straw yield was statistically at par with each other. Highest benefit: cost ratio was recorded in pre-emergence spray of isoproturon 0.5 kg a.i./ha+ one inter-culture at 40 DAS (2.61) followed by one inter-culture at 20 DAS and one hand weeding at 40 DAS (2.59). Therefore on the basis of pooled data of three year experiments, it can be concluded that higher seed rate of 15 kg per hectare of barnyard millet and integrated approach of isoproturon 0.5 kg a.i./ha and one inter culture at 40 DAS are effective in managing weed problems of barnyard millet.
