Abstract
The effect of various concentrations of Zinc as Zinc sulphate on the growth parameters and chlorophyll content of Triticum aestivum were studied. It is evident that the lower concentration of zinc proved to be beneficial to wheat with respect to all the parameters studied. Higher yield of wheat was obtained when 5mg/gm-1 was applied. As the zinc concentration in the soil were increased beyond 25mg/ gm-1 decreases in various parameters occurred. Higher concentration of zinc had toxic effect on the growth and yield production of wheat. The average of grain per ear was maximum in 5mgm/gm-' concentration of zinc and no of grains was 38.67. Quality of the grains was also effected with the very low and very high concentration of zinc. In higher conc. of zinc no. of grains was decreased to zero and quality of grain was also poor.
