Abstract/ Executive Summary:

Micronutrients is more affective as foliar application than soil application as its requirement in small amount. When any micronutrient is applied in soil the loss of nutrients is maximum than foliar application. In case of soil application it needed higher amount than foliar application. Zn is a micronutrient. To identify the efficiency of Zinc as foliar application. The result shows that in every treatments yield was increase over control. Highest yield was recorded in the treatment T₄ where 6 kg/ha zinc was applied. The rate of increase (%) over control was 28.85 in the case of treatment T₄. The statistically analysis showed that the effect of different treatments on the yield of tea was significant (F=9.70 at 5% level.). T₄ is the best treatment and T₃ is the second best treatment.
