Comparative study of Zn amended soil on the germination and growth of leguminous plants Pisum sativum cv.Azad and Pisum sativum cv.Arkel.

Abstract

A basic knowledge of the dynamics of Zn in soil, water and plants are important steps in achieving sustainable solutions to the problem of Zn deficiency in crops and human. The chief source of Zn pollution is from human activities. Metallic Zn is used in several industries although this heavy metal is required by the plants, however excess of this heavy metal is hazardous to the plants. Zinc reaches in our body through water and food chain and causes several diseases as well as inhibits several enzymatic reactions. There occurs uptake of this heavy metals by the crop plants, because farmers use Zn for the enhancement of growth and yield of their crop. Through food chain Zn reaches in our body and causes damage of protein molecules specially by blocking activity of enzymes. The use of Zn beyond the permissible limit has toxic effect on plants and animals. Therefore, it was of interest to study on the topic which are widely cultivated in measure part of U.P.
