| Experiment Title | Effect of biochar on aerobic rice and its residual effect on rabi knolkhol | ||
| Research Type | State Trial | ||
| Experiment Background | Biochar has emerged as an organic amendment with mineral nutrient elements and hold a promise to improve the soil quality and yield of crops in recent years.The biochar is found to have positive impact on soil fertility, resulting in an increase in crop yield without causing hazard to soil and water environment. Further, addition of biochar with biocompost and NPK fertilizers to soils has attracted widespread attention as a method to improve soil fertility and productivity. Biochar and biocompost application increased soil carbon sequestration and improve soil quality because of the vital role that carbon plays in chemical, biological and physical soil processes and many interfacial interactions. Knolkhol is a winter season crop and belongs to the family cruciferaceae. Knolkhol has a bulb-like swollen edible portion called knob that develops entirely above the ground. Both the green leaves and knobs are used as culinary at tender age and when the knobs become fibrous used for pickle purpose. Besides the vegetable contains many B-complex vitamins and helps in fighting cancer as well as asthma and lung problems.Keeping the beneficial effect of biochars, the present experiment has been proposed. | ||
