Title: Effect of tillage and weed management practices on weed dynamics, weed seed bank and grain yield of wheat in rice-wheat system
Abstract: A field experiment was conducted during two consecutive Rabi season of 2005–06 and 2006–07 at NEB Crop Research Centre of G.B. Pant UniversityofAgriculture and Technology, Pantnagar on sandyloam soilto find out the effect of tillage and weed management practices on weeds, weed seed bank in soil and grain yield of wheatgrown afterrice. Zerotill sownwheathad significantlylesserweed dryweight perunit areaas compared to conventional sown wheat. Phalaris minor, Melilotus indica and Chenopodium album seed density in soil were significantly lower under zero tillage as compared to conventional tillage from 0 to 5, 5 to 10 and 10 to 15 cm soil depths. Excellent suppression in weed density and dry weight and higher yield of wheat were obtained with two hand weeding under conventional tillage system. Under weedy situation, zero tillage was found better because of less weed emergence.
