The experiment was laid out in a split-split plot design with three replications under irrigation. Among all dates of sowing, significantly higher plant height, number of branches and dry matter production with yield and yield attributes like, number of pods per plant, number of seeds per pod, seed yield per plant (20.02 g plant-1) , thousand seed weight (44.91 g) and seed yield (1,798 kg ha-1) were recorded under D3 date of sowing. Application of high dose of fertilizer F3 recorded significantly higher seed yield (1,808 kg ha-1) and significantly higher values of yield components compared to F2 and F1. Similarly the growth parameters were significantly higher at F3 fertilizer compared to F2 and F1. Among genotypes significantly higher growth, seed yield and seed quality parameters were recorded in local genotype (1,712 kg ha-1) over variety SUN-053 (1,657 kg ha-1). Since dry matter is more in local genotype (98.55 g plant-1) so it is more suitable for growing as green manuring crop. Best treatment combination (D3G1F3) was sunnhemp local genotype sown during 1st FN of August applied with 37.5:75:37.5 NPK kg ha-1 recorded higher seed yield (1,999 kg ha-1), seed germination (81.50 %) and seedling vigour index (3431) over the other variety, dates of sowing and fertilizer dosages in the Northern Dry Zone of Karnataka (Zone-3).EnglishEffect of Genotypes, Date of Sowing and Fertilizer Application on Seed Yield and Quality of Sunnhemp (Crotalaria juncea L.)Thesis
