Abstract
A field experiment was conducted to study the effect of integrated weed management practices on growth, yield, quality of clusterbean and nutrient uptake by crop and weeds at Bikaner during Kharif 2013. Higher yield were recorded under weed-free treatment. Weed biomass was reduced significantly by pendimethalin 0.75 kg/ha as pre-emergence as well as imazethapyr and imazethapyr + imazamox as post-emergence. The highest total uptake of N (88.2 kg), P (17.9 kg) and K (70.8 kg/ha) by the crop was recorded under weed-free conditions.
