Effect of Zinc Based Nano Fertilizer on Physiological Parameter

A green house experiment was conducted to study the effect of conventional ZnSO₄ and Zn loaded nano carrier namely nano zeolite, manganese core shell, carbon sphere and ZnO. Among this treatments nano based zinc fertilizer had significantly increase chlorophyll SPAD value, IAA oxidase activities and total phenol content in rice crop. The study was carried out with five treatments viz., five forms of zinc in completely randomized block design and replicated in four. Finally, this study concluded that Zn loaded nano carrier release nutrients slowly and steadily during critical growth period thereby improved physiological parameter.
