Soybean is referred to as ‘meat of the field’ or ‘meat without bone’ (Abraham 2013). It is an annual antioxidant-rich grain legume that contains 40% protein content and 20% high quality oil (Ishaq and Ehirim 2012). Soybean is the primary source of the world’s supply of protein and vegetable oil. Augmented production of soybean has been observed to elevated world’s populace increase and reduced demand for protein and edible oil in future (Ishaq and Ehirim 2012) Abraham (2013) reported that over 80 percentage of the arena’s soybean crop is processed into meal and vegetable, which are used in the production of animal feeds. Soybean is the largest supply of oil in the international seed exchange with approximately 95 percentage consumed as edible…show more content…
It is one of the basic issues in farming and fertilization. Nutrient use efficiency is defined as capability of plant to absorbs, translocates or uses of a specific nutrient better than another plant under conditions of relatively low nutrient availability in the soil or growth media (Soil Science Society of America, 1997). (Sauerbeck and Helal, 1990) defined it as a plant yield per unit of nutrient supply. Nutrient loss to the environment occurs only when fertilizer or manure are applied at the above agronomic need (Roberts, 2008). (Baligar et al., 2001) reported that the reclamation of applied inorganic fertilizer is low in many soils with approximately 50% or lower for nitrogen, less than 10% for phosphorus and close to 40% for potassium. Sauerbeck and Helal (1990) reported that the importance of nutrient use efficiency is to meet world food demand, fulfill the nutritional requirements of crops, high yield, resistance to pest and diseases and environmental protection. (Baligar et al., 2001) observed that higher nutrient use efficiency through plant could help reduce fertilizer input costs, decrease the rate of nutrient losses and enhanced crop yield. Best management practices such as addition of crop residues, green manure, compost, animal manure use of cover crops, reduce tillage and avoiding burning of crop residues can significantly improve the level of soil organic matter and contribute to the sustainability of cropping systems and higher nutrient use efficiency. Nutrient use efficiency is affected by soil factors, crop factors, environmental factors, fertilizer management and technology (Baligar et al., 2001). (Rakshit, 2002, Helmers et al., 2014) reported that maintaining manure nitrogen application lower grain nitrogen confiscate the quantity of nutrients sufficient to keep soil nitrate level below the
