Response of Popular Varieties on Foliar Application of Micronutrients on Growth, Seed Yield and Quality in Greengram

Abstract

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).

Effect of Seed Biopriming on Growth, Yield and Economics of Rabi Green Gram (Vigna radiata L.) in Rainfed Condition of Balasore District of Odisha

“…This may have contributed to the increased translocation of nutrients into the plant without any loss, which in turn contributed to improved photosynthesis and resulted in a significant rise in plant height and branches per plant as corroborated by (Elankavi et al, 2019 andKavitha et al, 2020). Increased supply of nutrients during initial stages may also due to more nodulation by Rhizobium and rhizosphere effect through microbial activity modifies the plant itself by providing the plant growth and increasing the availability of elements to the root zone (Adhithya et al, 2023). Also increase in plant height of 50.6cm is recorded in biopriming with liquid PSB 5% (T 3 ) which is higher than the control (T 1 ).…”
