Effect of Long Term Application of Imbalanced and Balanced Fertilization on Soil Physical Properties in Vertisol under Rice Wheat Cropping System

India is the 2 nd most populated country in the world after China with a population of 17.74% of the total world population (www.worldmeters.info//). By 2025, India is going to be the world most populated country. In India, Rice (Oryza sativa L.) – wheat (Triticum aestivum L.) cropping system covers about 12 million hectares (Tripathi et al., 2011) and it is the backbone of country’s food security with a yield potential of 8-12 t/ha/year (Ladha et al., 2012). Kumar et al., (2016), by 2030, the demand of total food grain will reach 311Mt involving 122 Mt of rice, 115 Mt of wheat, 47 Mt of coarse grains and 27 Mt of pulses. The use of unbalanced fertiliser leads to an unhealthy plants. Therefore, use of balanced proportions of fertilizer and in sufficient quantity is necessary.
