Effect of Different Doses and Splits of Potassium on Storage of Onion

Deepa AH, Wagh AP and Nagre PK

The data found that, the physiological loss in weight, sprouting, rotting and black mould incidence were declined and number of marketable bulbs and TSS of bulb significantly increased during storage with increasing levels of potassium up to 60 kg ha-1 (K3) and with three split application of potassium (S3) respectively. Combined effect of different levels of potassium and its split application was statistically significant with K3S3 i.e. three split application of 60 kg ha-1 and maximum storage losses were obtained from K1S1 i.e. 40 kg ha-1 of potassium 100 % at the time of transplanting.
