 ABSTRACT

Zinc Deficiency in Soil of Rajasthan and its Management. In India, zinc (Zn) is now considered as fourth most important yield limiting nutrient in agricultural crops. Zn deficiency in Indian soils is likely to increase from 49 to 63% by 2025. meet out only 30 to 40% of zinc requirement meet out by soil and foliar application of zinc on crop plants while the remainder gets absorbed in clay colloids and become immobile and some parts may goes out to the environment due to soil and edaphic factors.  Only a small amount of applied zinc is utilized by the crop plants. Studying the solublization and mobilization of zinc in soil and interaction with other nutrients in various types of soils are essential for the precise recommendation and use of zinc. The soils of Alwar and Jhalawar have 0.50 ppm of available zinc while in Bhilwara soils it was found in traces indicating that the soils of these places may show deficiency symptoms. Total Zn content of different soil groups of Rajasthan ranged from 34.8 to 79.6 ppm. Available zinc was not found to be correlated with pH. So it is necessary to reduces zinc loss in these regions by using well management practices. It can help for increasing zinc availability in Rajasthan region.
