Abstract

A field experiment was conducted in sandy loam soil during winter season of 2017-18 and 2018-19. Significantly the lowest weed biomass production, highest available nutrients in soil and the maximum N and K content in weeds and crop was recorded with the application of irrigation at CRI+ active tillering stage. Whereas, irrigation at CRI+jointing+ booting+ flowering+milking stage was recorded maximum P content. Application of broadway (carfentrazone ethyl 20% + sulfosulfuron 25%WG) 100 g a.i. ha-1 at 35 DAS recorded significantly lowest weed biomass and the highest nutrient content in weeds and crop. Application of irrigation at CRI+jointing+ booting+ flowering+milking stage was recorded significantly the highest nutrients depletion by weeds and their uptake by crop. Significantly the lowest nutrients depletion by weed and their highest uptake of crop and the maximum available nutrients in soil were recorded with the application of broadway (carfentrazone ethyl 20% + sulfosulfuron 25%WG) 100 g a.i. ha-1 at 35 DAS. Grain (9.79 kg ha-1) and straw yield (4.54 kg ha-1) will be reduced by an increased in unit of nutrients depletion by weeds.
