A experiment was conducted during winter (rabi
) season of 2011-12 at Agricultural Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, Uttar Pradesh (India), situated under North East Plain Zone of the country. The geographical situation of the farm lies in the North-Gangetic Alluvial plain. The experiment was laid out in Factorial Randomized Block Design comprised of 14 treatment combinations along with three replications. The treatment comprising of seven varieties i.e.
Kranti, Rohini, Basanti, Maya, NRCHB-101, Ashirwad and Varuna and two weed treatments including weed free and weedy check The lowest density of monocot weed, total weeds and dry matter of weeds was recorded in Rohini, in case of dicot weed density lowest was recorded in Rohini which was at par with NRCHB-101. Whereas in case of growth attributes Rohini attended maximum Plan height over the rest of varieties. In case of number of leaf, chlorophyll content, primary and secondary branches it was observed that Rohini shows its superiority over rest of the varieties except NRCBH-101. It was noticed that significant higher grain yield was observed in Rohini (2102 kgha-1
) which was at par with NRCHB-101 and Basanti. In case of straw yield, harvest Index and oil content Rohini, NRCHB-101 and Varuna were shows their dominancy respectively during the period of investigation.
