The present study was undertaken with the objective to find out the response of mungbean varieties to foliar spray of nutrients and growth regulators on yield and seed quality. The treatments consisted of three varieties viz; Pant Mung 2 (small seeded), Pant Mung 4 (medium seeded) and Pant Mung 5 (bold seeded) and six foliar sprays (urea 2%, NPK 2%, DAP 2%, salicylic acid 100 ppm and indole butyric acid 100 ppm and control). Foliar spray of nutrients and growth regulators was done twice 40 and 55 days after sowing. The experiment was laid out in a Randomized Block Design with three replications. Results revealed that bold seeded variety Pant Mung 5 recorded the highest seed yield and yield attributes, whereas the highest biological yield was noticed in small seeded variety Pant Mung 2 with lowest harvest index. Seed quality parameters were also highest in bold seeded variety Pant Mung 5. In case of foliar sprays of nutrients and growth regulators, 2% DAP produced significantly higher yield which was at par with 2% urea and 100 ppm salicylic acid. Thousand seed weight was also significantly highest in foliar spray of 2% DAP followed by 2% urea. Protein content in seeds increased significantly in foliar spray with 2% urea whereas, other seed quality parameters such as germination percentage and vigour index were significantly highest in crop following foliar spray of 100 ppm salicylic acid. The data showed significant effect of interaction of varieties and foliar spray of nutrients and growth regulator on grain weight per plant and protease enzyme activity.
