Nanotechnology has drastically shepherded a magnanimous period in the global agricultural landscape. Nutrient use efficiency is one of the most imperative concepts for invigorate crop production systems, which can be influenced by various factors such as fertilizer management and soil and plant-water relationships. The nutrients are used with an objective of enhance the overall performance of crops and cropping systems by providing optimum nourishment and supporting sustainable agricultural production systems through contributions to soil fertility and other important soil quality components. Improvement in nutrient use efficiency has been today's most critical and formidable research issues. With the advent of green, modern agriculture techniques are not only confined to augment crop yield/food productivity but, aim to elevate the nutritional content of the food/crops. Various nano-structured formulations may also be developed in order to deliver active ingredients in response to environmental cues and biological demands more properly.
