Influence of Potassium, Zinc and Boron on Productivity of Wheat In an Acid Alfisol
Keywords:
Potassium, Zinc, Boron, Growth, Yield Attributes, Wheat Yield, Alfisol.Abstract
To evaluate the effect of potassium, zinc and boron on wheat productivity, the present investigation was undertaken at the experimental farm of Department of Soil Science, College of Agriculture, CSKHPKV, Palampur. The experiment comprised of sixteen treatments with four levels of K (0,50,100 andl50% of recommended dose), two levels of Zn (0 and 101^ ha ‘) and two levels of B (0 and 1 kg ha-1) in factorial randomized block design. Application of K @ 50,100 and 150 % of recommended dose increased plant height, dry matter accumulation, total and effective tillers per metre row length, grains per ear and test weight significantly. Application of Zn (10 kg ha-1) and B (1 kg ha-1) influenced the growth and yield attributes of wheat significantly. Highest grain (42.52q ha ‘) and straw (66.80q ha ‘) yield of wheat was recorded under 150 % of recommended dose of potassium. Application of 150 % of recommended dose of K increased grain and straw yield by 44 and 47 % over no K, respectively. Application of Zn (10 kg ha-1) increased grain and straw yield by 11 and 10 % over no Zn, respectively. The increase in grain and straw yield with the application of B (1 kg ha-1) was 5.6 and 6.3 %, respectively.Downloads
