Increase in world population in the past decade increased the crop productivity to satisfy the needs of people in different countries. Fertilizers have been used for the past many years in agriculture for the benefit of farmers. Green revolution had led to the increased consumption of traditional fertilizers which resulted in severe environmental hazards. Nutrient use efficiency of traditional fertilizers is very low. To overcome all these drawbacks in a better way, nanotechnology can be a ray of hope. Nanofertilizers are the important tools in agriculture to improve crop growth, yield and quality parameters with increase nutrient use efficiency, reduce wastage of fertilizers and cost of cultivation. A nanofertilizer comprises nanoformulations of nutrients deliverable to plants, enabling sustained and homogeneous absorption. Nanofertilizers are very effective for precise nutrient management in precision agriculture with matching the crop growth stage for nutrient and may provide nutrient throughout the crop growth period. Nanoparticles have high surface area, sorption capacity, and controlled-release kinetics to targeted sites making them smart delivery system. Nanofertilizers provide higher surface area for different metabolic reactions in the plant which increase rate of photosynthesis and produce more dry matter and yield of the crop. It also prevents plant from different biotic and abiotic stress.Nanofertilizers can improve overall crop productivity by enhancing the rate of seed germination, seedling growth, photosynthetic activity, nitrogen metabolism, and carbohydrate and protein synthesis. As a result, use of nanofertilizers in agriculture can prove to be the best sustainable solution for increasing crop production and yield.
