A field experiment was conducted to study the influence of 2 crop geometries (30 and 45 cm), 3 cultivars ('Avarodhi', 'Radhey' and 'Pant G 11 4') and 2 weed-management practices (weed-free and weedy) on crop- weed competition in chickpea (Cicer arietinum L.) during the winter seasons of 1996-97 and 1997-98 at Agri- cultural Research Farm, Varanasi, Uttar Pradesh. Chickpea cultivar 'Avarodhi' proved better competitor for space, soil moisture and nutrient compared to 'Radhey' and 'Pant G 144'. Row spacing of 45 cm accumulated more nu- trient and utilized soil moisture efficiently in comparison to 30 cm row spacing. Full-season weed competition re- duced grain yield, nutrient accumulation and utilization of soil moisture in chickpea cultivars in comparisn to full- season weed free. Variety 'Avarodhi' and 45 cm row spacing recorded the highest grain yield, net return and benfit : cost ratio compared to 'Radhey' and 'Pant G 114' and 30 cm row spacing respectively.References
