Nanotechnology has opened up a number of scopes for novel application in the field of agriculture industries, because of several physico-chemical properties of nanoparticles (NPs), that is high surface area, high reactivity, tunable pore size and particle morphology. Nanoparticles provide smart delivery of fertilizers. Some of the nano polymers that are used in biofertilizers are albumin, alginate or chitosan. Chemical fertilizers resulted in higher productivity as well as caused environmental hazards. To overcome these drawbacks, nanotechnology can be a ray of hope. Nanofertilizer improves crop growth, yield and quality parameters with increased nutrient use efficiency, reduction in wastage of fertilizer and cost of cultivation. It promotes direct entry of nutrients into the plant system, to reduce wastage. Some crops may have protein deficiency, to overcome all these drawbacks. The extraction of protein was carried out according to the method of Maronach and Diosady. The extracted protein sample was coated with nanopolymers. Through Foliar application, bio-nanofertilizers provide proteins to the crops (Foliar application – A technique of feeding plants by applying liquid fertilizer directly to the leaves. Plants are able to absorb essential elements through their leaves). Foliar application of nanofertizer leads to higher nutrient efficiency (NUE) and gives rapid response of growth.
