ABSTRACT
An experiement entitled “Effect of different doses and splits of potassium on growth and yield of onion” was carried out at Main Garden, Department of Horticulture, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during 2015-16. The experiment was laid out in Factorial Randomized Block Design with three replications and two factors i.e factor ‘A’ viz., K1 - 40 kg, K2 - 50 kg , K3 - 60 kg and K4 - 70 kg of K ha⁻1 and factor ‘B’ S1, - 100 % at the time of transplanting , S2 - 50 % at the time of transplanting + 50 % at 30 DAT and S3 - 33.33 % at the time of transplanting + 33.33 % at 30 DAT + 33.33 % at 60 DAT with 12 treatment combination. K3 was found significantly superior in respect of plant height ( 56.71cm), number of leaves per plant (10.22), leaf area ( 232.13 cm2) fresh and cured bulb weight (68.82 and 65.36 g), diameter of bulb (5.50 cm), marketable bulb yield per plot (6.68 Kg), total yield per plot (7.70 Kg).The split application method S3 was found significantly superior in respect of plant height, number of leaves per plant, leaf area at 30, 60 and 90 DAT respectively, fresh and cured bulb weight, diameter of bulb, marketable bulb yield per plot, and total yield per plot. Combined effect of different levels of potassium and its split application was statistically significant with K3S3 and lowest bulb yield was obtained from K1S1.
Key words: Potassium, Splits, Growth, Yield, Onion.
