Efficacy of different methods of zinc application in groundnut, Arachis hypogaea

摘要

Groundnut is an important oilseed crop grown in soils of diverse physico-chemical characteristics. Deficiency of micronutrients especially, zinc has been reported to adversely affect the yield and significant response of Zn application on groundnut yields has been reported (Bahl et al., 1986, Sutaria and Patel, 1987; Revathy et al., 1997). The information about the efficacy of different methods of Zn deficiency correction in groundnut is very meagre. The present investigation reports the comparisonof the performance of different Zn sources, rates and their method of application on yields, Zn concentration and uptake by groundnut.
