OTHER EXPERIMENTAL DETAILS Gross Plot Size :5.00 m x 3.60 m Net plot Size :4.40 m x 3.00 m Distance between replications :1.5 m Distance between the plots : 1.0 m Spacing (R-R):30 cm Variety:JS Seed Rate:70 kg/ha Fertilizer application:20:60:20 N:P 2 O 5 :K 2 O kg/ha

OBSERVATIONS TO BE RECORDED A. Pre harvest studies On Weeds  Weed flora of experimental field at 30, 60 DAS in weedy check plots  Species wise weed density before application of herbicide, at 15, 30, 45 Days after Application and harvest  Species wise weed biomass before application of herbicide, at 15, 30, 45 Days after Application and harvest On Crop  Plant population per meter row length at 30 DAS and harvest  Plant height at 30, 60, 90 DAS and harvest  Number of branches per plant at 30, 60, 90 DAS and harvest  Dry weight of plant at 30, 60, 90 DAS and harvest  Leaf area at 30 and 60 DAS  Nodules per plant at 45 and 60 DAS  Dry weight of nodules at 30,45 and 60 DAS

B. Post-harvest Studies  Filled pods/plant  Unfilled pods/plant  Seeds/pod  Seed index  Seed yield (kg/plot)  Stover yield (kg/plot)  Oil content of seed (%)  Protein content of seed (%) C. Data to be computed  Weed index(%)  Weed control efficiency (%)  Leaf area index  Seed yield (kg/ha)  Stover yield (kg/ha)  Harvest index (%)
