Sustainable Rice Production System as Influenced by Organic Manures and Biofertilizers

Agriculture continues to be the key stream of India's economy. Nearly two third of the Indian population still depend on agriculture. The past achievement in food production was attributed to the availability of land, crop varieties with high yield potential, expansion in irrigation resources, increasing use of fertilizers to meet the nutritional requirement of crop, but the current situation is different. Modern agricultural practices and newer technological process have introduced another kind of pollution. Continuous use of inorganic fertilizers and neglecting of organic and bio fertilizers paved the way of deterioration of soil health and increased the ill effects of human beings and animals. Today, the use of organic manure in agriculture is considered an important strategy in the effort to preserve the global environment. Organic agriculture builds the health of the soil, providing the foundation for healthy crops and a livelihood for good stewards of the land. A healthy soil effectively supports plant growth, protects air and water quality and ensures human and animal health. Field experiment was conducted at Experimental Farm, Annamalai University in the winter (December, 2015- March 2006) aimed at understanding the effect of organic manures and biofertilizers on sustainable production of rice. Research results have established the beneficial effects of organic manures and biofertilizers on soil health and crop yields. In order to maintain high, crop yields and improve soil quality proper use of organics are recommended.
