Abstract
Nutrient use efficiency (NUE) is the part of a larger concept of resource use efficiency in agriculture which is a cause of concern for the present as well as the future of sustainability in agriculture.The nutrients applied to soil if not utilized by the plants find their way into the water resources and atmosphere which can increase the ecological cost.There are various measures of nutrient use efficiency which are suitable in different situations as well as for the nutrients.Among all the factors determining NUE, fertilizer factors are the most important.The various measures included in fertilizer factor are balanced fertilization, addition of organic matter, plant growth promoting micro-organisms, use of advanced form of fertilizers, use of modern equipment including Soil Plant Analysis Development and understanding of nutrient interaction and consequent antagonistic and synergistic effects on crop plants.
