Evaluation of Nano Structured Slow Release Fertilizer on the Soil Fertility, Yield and Nutritional Profile of Vigna radiata

Background: The excessive use of fertilizers and pesticides has distorted soil composition, fertility and integrity with non-desirable environmental and ecological consequences. A strategy was designed to prepare a nano structured slow release fertilizer system that delivers nutrients and plant growth promoting rhizobacteria simultaneously. Slow release nano phosphate and potash fertilizer was prepared by blending the nano emulsion of fertilizer with neem cake and PGPR. Slow release nano phosphate and potash fertilizer was prepared by blending the nano emulsion of fertilizer with neem cake and PGPR. Few patents relevant to the topic have been reviewed and cited. Keywords: Nano slow release fertilizer, nitrogen, phosphorus, potassium, soil fertility, Vigna radiata, yield.
