ABSTRACT
A field experiment was conducted to study the effect of integrated weed management practices on growth, yield, quality of clusterbean and weeds at Bikaner during kharif 2013. Weed-free treatment recorded the highest dry matter production, pods/plant, seeds/pod, seed and straw yield as well as lowest weed density and dry weight of weeds, which were at par with pendimethalin 0.75 kg/ha, imazethapyr 40, 50 and 60 g/ha and imazethapyr+imazamox 40, 60 and 80 g/ha. Maximum net returns of Rs. 54,608/ha were obtained with weed-free treatment, followed by Rs. 53,277/ha with pendimethalin 0.75 kg/ha alone. Benefit : cost ratio was highest with pendimethalin 0.75 kg/ha alone (3.88), followed by weed-free treatment (3.81).
Key words :Clusterbean, herbicide, pre-emergence, post-emergence
