Abstract
Two hundred soil samples collected from Agra district were analyzed for their potassium fractions. The lattice, HCl soluble, fixed, exchangeable and water soluble K contributed 60.4, 29.6, 9.3, 0.64 and 0.06% towards total soil K in these soils. Highly significant positive relationships amongst various fractions of soil K indicated existence of a dynamic equilibrium between different forms of K. Vegetable crops responded significantly to potassium up to 90 kg K2O ha−1. The content and yield of protein in both the crops increased significantly with the addition of potassium. The maximum net return of Rs. 1, 46, 468 and 98, 752 and B:C ratio of 2.24 and 1.55 were recorded in cauliflower and onion, respectively with 120 kg K2O ha−1. Nitrogen uptake by cauliflower and onion progressively increased from 103.8 to 165.5 and 45.2 to 70.0 kg ha−1, respectively with application of 120 kg K2O ha−1. The uptake of P, K and S by both the crops also increased with graded levels of potassium. Percent utilization of added K by cauliflower and onion was maximum with 60 and 90 kg K2O ha−1, respectively.
