Effect of Nitrogen, Zinc and Boron on Growth, Yield Attributes and Yield of Wheat under Mid Hill Conditions of Himachal Pradesh
Keywords:
Nitrogen, Zinc, Boron, Growth, Yield Attributes, Yield, Wheat.Abstract
A field investigation was carried out at experimental farm of Department of Soil Science, College of Agriculture, CSK HPKV, Palampur with sixteen treatments consisting of four levels of N (0, 50,100 and 150 per cent of recommended dose), two levels of Zn (0 and 10 kg ha-1) and two levels of B (0 and 1 kg ha-1) in factorial randomized block design. Nitrogen application @ 50, 100 and 150 per cent of recommended dose increased plant height, dry matter accumulation, total and effective tillers and grains per ear significantly. Similarly, application of Zn (10 kg ha-1) and B (1 kg ha-1) improved these growth parameters and yield attributes of wheat significantly. 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 10 kg Zn ha-1 increased the grain yield by 9.7 per cent. Boron application @ 1 kg ha-1 increased grain yield by 8.1 per cent.Downloads
