Potassium in relation to yield, quality and economics of Brinjal - Cabbage cropping system

Field experiment was conducted at College Farm, College of Agriculture, PJTSAU, Rajendranagar, Hyderabad during kharif and rabi (2013-2014) with brinjal – cabbage cropping system in Randomized Block Design with seven treatments replicated thrice. The treatments include recommended dose of potassium along with different combinations of potassium were applied keeping in view the K – fixing capacity of the soil (0, 60, 73.5, 87, 100.5, 114, 127.5 kg K2O ha-1 ). With increase in level of potassium yield and the quality parameter ascorbic acid content increased. In Brinjal – cabbage cropping system with increase in potassium levels the net returns increased as the yield was increased. The highest net returns of Rs 150517 per hectare recorded in treatment T7 (Rec. dose of K2O + 2.5 X kg K2O ha-1 i.e., 127.5 kg K2O ha-1 ) followed by T6 (131084 Rs ha-1 ) with a benefit cost ratio of 1.72 and 1.50 respectively. | Potassium in relation to yield, quality and economics of Brinjal - Cabbage cropping system
