Abstract:
Field experiments were conducted at Research Farm, Krishi Nagar, JNKVV, Jabalpur (M.P.), between the year 2003-04 and 2009-10 under irrigated production system to compare organic, integrated and chemical fertilizer inputs packages in scented rice (Oryza sativa L.) –Potato (Solanum tuberosum) a high value cropping system. The present investigation has been started since the kharif season of the year 2003-04 under the AICRP on Integrated Farming System. Seven different nutrient treatments, 6 of them using organic inputs (FYM, vermicompost, rock phosphate neem cake, green manure and bio-inoculants) and 1 each having integrated (50% NPK through fertilizers + 50% N through FYM) and 100% NPK through fertilizers + Zn as per soil test values were studied in RBD with 3 replications. In organic treatment decline in yield was observed since 2003-04 to 2006-07 and again increases in yield was noticeable in rice. These treatments followed a steady increase and registered 20 to 50% more yield at the end of study compare to first years. Effect of different organic input packages on potato tuber yield was not stable over the years. Total productivity of scented rice-potato cropping system in terms of rice equivalent yield of the system (78.48 q/ha/day) and total net returns (Rs/ 64554) was highest in chemical treatments closely followed by integrated input use. Long term use of organic manures like FYM, vermicompost, neem cake, composed crop residue appreciably increased the organic carbon (7.50g/kg) over initial value (6.40g/kg). Integration of the organic and inorganic inputs significantly increased the availability of N, P and K in soil over chemical treatment alone.
