The influence of seed invigoration on seed yield and quality was studied in two seasons, i.e., summer and kharif. Among the seasons studied, seed quality parameters significantly differed for both seasons. Summer recorded the highest values in growth and yield parameters, viz., field emergence and plant population at harvest (91.75 and 87.75 %, respectively), number of nodules (35.71), seed yield (q/ha) (3.49), and seed quality parameters, viz., seed germination (%) (g) (91.7), and seedling vigour index I and II (3392 and 2252, respectively). But the lowest hard seeds were recorded in kharif (71.71%). Among treatments studied, 1 % ZnSO4 recorded the highest values in growth and yield parameters, viz., field emergence and plant population at harvest (96.50 and 91.17 %, respectively), number of nodules (38.50), pod length (cm), and number of seeds per pod (11.00 and 12.23, respectively). also in seed quality parameters, viz., seed germination (%) and 100 seed weight (g) (94.7 and 3.78, respectively), shoot length and root length (25.93 and 14.51 cm, respectively), mean seedling length (cm) and mean seedling dry weight (mg) (40.44 and 278, respectively), seedling vigour index I and II (3829 and 2636, respectively), and total dehydrogenase activity (A480nm) (1.825).

Effect of foliar application of micronutrients on seed yield and quality were studied in three green gram varieties i.e., KKM-3, WGG-42 and TRCRM-147. Among three varieties, seed quality parameters were significantly differed in yield and seed quality parameters. KKM-3 recorded the highest in growth and yield parameters viz., plant height at 30 DAS and 60 DAS (14.55 and 30.83 cm, respectively), number of nodules and number of branches per plant (28.43 and 6.65, respectively), number of pods per plant and pod yield per plant (g) (12.96 and 11.98, respectively), seed yield per plot (g) and seed yield (q/ha) (204.42 and 3.24, respectively) also, in seed quality parameters viz., number of seeds per pod and 100 seed weight (g) (11.67 and 3.93, respectively), total dehydrogenase activity (1.836) (A480nm) respectively) and protein (24.01%). But, highest germination (%), mean seedling dry weight (mg) and seedling vigor index-II were recorded in WGG-42 (96.07, 220 and 2111 respectively) and highest mean seedling length (cm) and seedling vigor index-I recorded (33.70 and 3046 respectively) in TRCRM-147. Among foliar treatments studied seed quality parameter were significantly differed. FeSO4 recorded the highest in growth and yield parameters viz., plant height at 30 DAS and 60 DAS (15.31 and 31.49 cm, respectively), number of nodules and number of branches per plant (32.10 and 12.83, respectively), number of pods per plant and pod yield per plant (g) (14.11 and 7.60, respectively), seed yield per plot (g) and seed yield (q/ha) (234.18 and 3.72, respectively) also, in seed quality parameters viz., 100 seed weight (4.16 g), mean seedling dry weight (220 mg), seedling vigor index-II (2049), total dehydrogenase activity (1.939) (A480nm) and protein (24.24%) But, ZnSO4 recorded highest in number of seeds per pod (12.09), germination (94.89%), mean seedling length (33.89 cm) and seedling vigor index-I (3217).
