Effect of Nitrogen, Zinc and Boron on Nutrient Concentration at Maximum Tillering of Wheat

Abstract

A field investigation was carried out at Palampur with sixteen treatment combinations consisting of four levels of N (0, 50,100 and150 per cent of recommended dose), two levels of Zn (0 and 10kg ha-1) and two levels of B (0 and 1kg ha-1) in factorial randomized block design. Highest grain (45.83 q ha-1) yield of wheat was recorded under 150 per cent of recommended dose of nitrogen which was 84.8 per cent higher than control. Application of 10kg Zn ha-1 increased the grain yield by 9.7 per cent. Similarly, boron application @ 1 kg ha-1 increased grain yield by 8.1 per cent. In general, application of nitrogen increased the concentrations of N, P, K, Mn, Fe, Cu, Zn and B in plants at maximum tillering of wheat. N, K, Mn, Cu and B concentration of wheat at maximum tillering increased with increasing level of nitrogen upto 150% recommended dose of nitrogen.
