Abstract
A field experiment was carried out during kharif seasons of 2012 at CRC of SVPUA and T, Meerut to evaluate the weed dynamics and performance of urdbean under integrated effect of land configurations and weed management regimes. The experiment was laid out in split plot design with three replications. In main plot factor, four land configuration i.e. Line sowing (30 cm), Ridge method, Broad bed method (30 cm) and Broadcast sowing and in sub plot factor, four method of weed management practices, i.e. Pendimethalin @ 1.5 kg a.i /ha as pre-emergence, two hand weedings at (20 and 40 DAS), and Quizalofop ethyl @50 gm a.i /ha as post emergence and control were tested by using F test. The study on weeds and crop growth parameters was made on quadrate (1 m2 ) basis, whereas the yield attributes and yield were calculated on net plot area basis (12 m2 ). The economical studies were done on the basis of prevailing market prices of input and output. The results indicated that weed population and dry weight of weeds were significantly reduced with the application of Quizalofop ethyl @50 gm a.i /ha as post emergence over Pendimethalin @ 1.5 kg a.i /ha as pre-emergence, Two hand weedings at (20 & 40 DAS) and control. Plant population, growth parameters viz., plant height, number of trifoliate leaves and dry matter accumulation and yield attributes viz., number of pod plant-1 , 100 seed weight, biological yield, harvest index found superior by using Quizalofop ethyl @50 gm a.i /ha as post emergence than Pendimethalin @ 1.5 kg a.i /ha as pre-emergence, Two hand weedings at (20 & 40 DAS) and control. This treatment also fetched Rs. 40631 and 53753 net and gross return, respectively. Moreover, under land configurations, Broad bed method (30 cm) showed highest values of above parameters followed by Ridge method, Line sowing (30 cm), and Broadcast sowing. Apart from above it also bring significantly reduction in weed population and dry weight of weeds. Thus, broad bed method in combination with Quizalofop ethyl @50 g a.i. / ha as post emergence may be suggested for effective control of weeds in urdbean with maximum net return.
