Abstract

The experiment was laid out under a factorial RBD design, with three replications comprising sixteen treatments. The treatments consisted of four doses of potassium, i.e., 40, 50, 60 and 70 kg/ha and four concentrations, viz., 0, 100, 200 and 300 ppm of GA3. The data analysis revealed that the minimum days to seed harvest (111.79 days), number of seeds/siliqua (6.25), length of siliqua (5.90cm), 1000-seed weight (9.55 g), seed yield/plant (18.09 g), seed yield/ha (2.19 q), germination percentage (93.13%) and seed vigour index (249.06) were recorded with 200 ppm GA3 application. Similarly, minimum days to seed harvest (118.66 days), number of seeds/siliqua (5.55), length of siliqua (5.13 cm), 1000 seed weight (9.12 g), seed yield/plant (15.16 g), seed yield/ha (1.88 q), germination (86%) and seed vigour index (200.12) were recorded with 50kg/ha K2O application. The combination of 200 ppm GA3 along with 50 K2O/ha proved to be the most superior treatment combination for minimum days to seed harvest (109.35 days), number of seeds/siliqua (6.33), length of siliqua (6.03 cm), 1000-seed weight (9.80 g), seed yield/plant (18.50 g), seed yield/ha (2.26 q), germination (95%) and seed vigour index (255.33).
