 ABSTRACT

An experiment was carried out at the Instructional Farm, College of Agriculture, Swami Keshwanand Rajasthan Agricultural University, Bikaner during rabi 2015-16 on loamy sand soil. The experiment was laid out in split-plot design with three replications, assigning twenty treatments consisting of four date of sowing (15 October, 30 October, 15 November and 30 November) as main plot treatments and five weed control measure (Weedy check, Weed free, Pendimethalin @ 0.75 kg/ha as pre emergence, Imazethapyr @ 20 g/ha at 20 DAS as post emergence and Quizalofop@ 37.5 g/ha at 20 DAS as post emergence) as sub-plots.
The results revealed that early sowing (15 October,) reduced the weed density, its dry matter accumulation, nutrient depletion by weeds and higher crop yield. Among different chemical weed control measures, pendimethalin at 0.75 kg/ha as PE recorded the lowest weed density and higher yield. Imazethapyr @ 20 g/ha at 20 DAS as PoE resulted in significantly lowest dry matter accumulation, nutrient depletion by weeds and higher weed control efficiency (69.90 percent). 

Keywords: Pendimethalin, Quizalofop and imazethapyr, Weed control efficiency, Chickpea
