Abstract


Several studies have proved pond ash a resourcematerial for crop production. It is a reservoir of a number of macro and micronutrients that proved to be an economical soil amendment to improve thephysical (texture, water holding capacity, pH, EC, etc.) and chemical (enhancethe absorption of B, Cu, Co, Fe, Mg, Mn, Mo, Se, Zn, etc.) properties of soil andyield of variety of agricultural crops, although, it is deficient in nitrogenand phosphorus. By amending fly ash with organic and bio fertilizers (Azotobacter and AM fungi, etc.)productivity of crops could be enhanced especially under adverse environmentalconditions. The kharif production ofonion is highly vulnerable due to erratic monsoon, cloudy weather, constantdrizzling which aggravate the problems like foliar as well as soil bornediseases and intensive weed. Due to this, kharifseason contributes only 15% to the total onion production in India. Thepresent study demonstrates the optimization and utilization of fly ash with biofertilizers to enhance the kharif onionproduction and the solution to overcome the shortage of onion in the months of Novemberto January due to exhaustion of stored stock of rabi.
