ABSTRACT
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 (60 kg K2O ha-1) along with different combinations of potassium were applied keeping in view the K – fixing capacity (X) of the soil. The results revealed that, the highest fresh fruit yield of 11.2 t ha-1 (brinjal) and fresh curd yield of 31.5 t ha-1 (cabbage) were recorded in T7 (Rec. dose of K2O + 2.5 X kg K2O ha-1 i.e., 127.5 kg K2O ha-1) and the lowest was recorded at T1 (control, No K). With increase in levels of potassium drymatter yield, nutrient content, uptake and yield was increased in both brinjal and cabbage crops, this could be attributed to enhanced crop growth with increased nutrient translocation and utilization by plants resulting in higher yield.
Key words :
Brinjal, Cabbage cropping system, Drymatter, K-fixing capacity, Potassium status, Yield attributes.
