Effect of Gypsum and Zinc Application on Growth and Yield in Groundnut (Arachis hypogaea L.)

摘要

A field experiment was conducted ta study the effect of gypsum and zinc application on growth and yield in two different cultivars of groundnut Application of different .levels of gypsum significantly increased the number of branches, root dry weight,leaf area index and flower to pod ratio and thereby yield of groundnut and increased further when sine as zinc sulphate was added with gypsum. Highest kernel yield was obtained with gypsum @ 750 kg ha~(-1) + Zn @ 25 kg ha~(-1), followed by gypsum @ 500kg ha~(-1) + Zn @ 25 kg ha~(-1). Among the two cultivars cv. G-201 (semi-spreading type) was more responsive to gypsum and zinc application and superior to cv. TMV-2 (bunch type).
