Continuous chemical fertilizer use deteriorates the soil health by breaking down soil particle. Increase the soil acidity, enhance soil erosion, encourage, decrease microbial activity and prohibits the proliferation of roots. But organic fertilizer use increasing the soil health by improving soil structure, minimize soil erosion increase microbial activity, increase water holding capacity and decrease the use of chemical fertilizer. To study the minimum rate of chemical fertilizer use in combination with organic fertilizer an experiment was laid out at BTRI farm. Highest yield was recorded in the treatment T4 18.41% where 75% of chemical fertilizer was applied with one ton WCOF/ha.
