ABSTRACT
Field experiment was conducted to study the effect of sowing methods and foliar sprays of micronutrients, growth regulators and their interaction on mother bulb growth and yield of onion during kharif 2016 and 2017 at Seed Unit, UAS, Raichur. From the present investigation, it was notified that the significant increase in the growth and yield parameters were noticed in direct sowing method viz., number of leaves per plant (8.74) & plant height (50.00 cm) at 105 DAS, bulb fresh & dry weight (76.44 & 10.62 g, respectively) and total bulb yield (256.4 q/ha) over transplanting (8.13, 48.42 cm, 73.56 g, 9.52 g and 239.3 q/ha, respectively). In case of foliar spray the ZnSO4 @ 0.5 per cent registered significantly higher values for all the growth and yield parameters viz., number of leaves per plant (9.65) & plant height (52.98 cm) at 105 DAS, bulb fresh & dry weight (82.39 & 11.12 g, respectively) and total bulb yield (256.4 q/ha) followed by GA3 @ 100 ppm and the lowest in control (7.37, 47.75 cm, 68.63 g, 8.86 g and 221.3 q/ha, respectively). Whereas, significantly highest optimum size mother bulb yield recorded in transplanting (190.50 q/ha) over direct sowing (179.18 q/ha).
