| Experiment Title | Effect of enriched biochars on crop productivity and soil health in aerobic rice based cropping sequence | ||
| Research Type | State Trial | ||
| Experiment Background | Rice (Oryza sativa L.) is one of the major staple food crops for more than half of the world population and is cultivated in 113 countries of the world. Due to continuous submergence of soil and application of excess chemical fertilizers, paddy soils are undergoing degradation by loss of organic matter. In addition to this continued and unbalanced use of chemical fertilizers also deteriorated the soil, affecting the microbial activity and also caused environmental pollution, although rice is a major food crop under wetland which contributes handsomely to global rice supply. Aerobic cultivation entails the growing of rice in aerobic soil, with the use of external inputs such as supplementary irrigation and fertilizer and aiming at high yields. Growing rice aerobically saves water by eliminating continuous seepage and percolation, reducing evaporation and eliminating wetland precipitation. Biochar application increased soil carbon sequestration and improve soil quality because of the vital role of carbon soil in chemical, biological and physical fertility and many interfacial interactions. To sustain rice based agriculture, efficient cropping system can contribute to a great extent. An increase in demand for pulses can be successfully met through crop diversification in the rice based cropping system. The inclusion of pulses in rice-based crop sequences in south Gujarat condition has become attractive because of the high yield and remunerative. Therefore, it is a need to find out the effect of biochars on crop productivity and soil health in rice based cropping sequence. Keeping above facts in sight, the present experiment is planned. | ||
