Studies on effect of different PGR’s and their application method on yield and yield attributing parameters of onion (Allium cepa L.) cv. N-53

Abstract

The present experiment was conducted at Horticultural Research cum Instructional Farm, Indira Gandhi Krishi Vishwavidyalaya, Raipur (C.G.) during Rabi season of year 2022-23 and 2023-24 with onion cultivar N-53. The experiment was comprised of eighteen treatment combinations of GA3, NAA and Brassinoloides and their application methods with one control (water spray). The outcome showed that because of the impact of PGR’s maximum polar diameter (cm), equatorial diameter (cm), weight of fresh bulb (g), bulb yield per plot (kg), bulb yield per hectare (q), weight of dry bulb (g), neck diameter (cm) and number of scales was recorded in P4 (GA3 60 ppm). Due to effect of method of application maximum polar diameter (cm), equatorial diameter (cm), weight of fresh bulb (g), bulb yield per plot (kg), bulb yield per hectare (q), weight of dry bulb (g), neck diameter (cm), number of scales was recorded in M3 (Seedling Dipping + Foliar Spray). Interaction of PGR’s and method of application maximum polar diameter (cm), equatorial diameter (cm), weight of fresh bulb (g), bulb yield per plot (kg), bulb yield per hectare (q), weight of dry bulb (g), neck diameter (cm) and number of scales was recorded in P4M3 (GA3 60 ppm - Seedling Dipping + Foliar Spray).
