Modern fertilizer technology and the, increasing frequency with which micronutrients are involved in fertility problems emphasizes the need for an appraisal of these nutrients in relation to cotton production. Among the micronutrients, zinc has assumed greater significance due to the wide occurrence of its deficiency. There are many reports indicating the favourable response of cotton to micronutrients. Application of zinc sulphate to zinc deficient soil improved fertilizer use efficiency and resulted in higher seed cotton yield. However, the work done on micronutrients in cotton was abysmally low and therefore, elaborate experimentation are yet to be made so as to prescribe site specific recommendations.
