Surface Modified Nano-Zeolite Based Sulphur Fertilizer on Growth and Biochemical Parameters of Groundnut

A glasshouse experiment was conducted to study the effect of conventional sulphur andsurface modified nano-zeolite based sulphur on the plant height, number of branches, total chlorophyll content and root nodule count of groundnut at various growth stages. The study was carried out with nine treatments viz., two forms of sulphur as four levels of conventional sulphur as calcium sulphate and four levels of surface modified nano-zeolite based sulphur and control in completely randomized block design and replicated in thrice. The results indicated that application of sulphur as surface modified nano-zeolite @ 30 kg S ha⁻¹ was recorded highest plant height, number of branches, total chlorophyll content and number of root nodule at all the growth stages of groundnut. Finally, this study concluded that surface modified nano-zeolite based sulphur release nutrients slowly and steadily during critical growth period thereby improved growth and biochemical parameters since better sulphur uptake of groundnut.
