Abstract:

Potassium (K) is one of the major nutrients taken up by the plant in large quantities. Adequate amount of potassium is known to increase crop resistance to various diseases and also having important role in bulb formation in onion. An on farm trial was conducted to evaluate the effect of method of planting and different level of potassium in onion on the soils tested medium in K status, trial consists of four levels of Potassium replicated thrice in randomised block design. The four levels of potassium were as: 0 kg K2O/ha, 50 kg K2O/ha, 75 kgK2O/ha and 100kg/ha. Experiment results indicated that all the yield contributing characters responded to applied potassium. Bulb yield also responded to potassium application. It increased from 320.7q/ha to in the control plot to 366.6q/ha in treatment where 100 K2O/ha was applied in 2012 and from 350 q/ha to 360.3 q/ha in 2013. TSS content also increased from 9.2 to 13.6 % in 2012 and from 10.80 to 11.89 in 2013 with increase in application of potassium from 0 kg K2O /ha to 100 Kg K2O. The behaviour of the onions regarding weight loss and sprouting stored at room temperature was recorded. It was observed that with increase in potash content there was decrease in moisture loss and sprouting. Highest sprouting percentage (6.7% and 12.4 %) at 30 and 90 DAS respectively was observed in control plots Sprouting was highest in control plots both at 30 and 90 days after storage.
