Study the Effect of Integrated Nutrient Management on Yield and Nutrient Uptake in Pumpkin

AN Alekar, PS Hirve, GN Deshmukh and RP Kharde

<p">An experiment entitled “Integrated nutrient management studies in pumpkin” was carried out during summer season of 2011 at Horticulture Farm, Department of Horticulture, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. The experiment conducted in Randomized Block Design with three replications using cv. Arka chandan, with ten treatments, two kinds of organic manures (FYM and Vermicompost) alone and in combination with two kinds of biofertilizers (Azotobacter and PSB) and reduced doses of chemical fertilizers were tested in comparison with RDF.
On the basis of results, the application of 50:25:25 Kg NPK ha^-1 + FYM 25 t ha^-1 + seed treatment with PSB to the crop found to be sound integrated practice. The integrated use of inorganic fertilizers, organic manures and biofertilizers had a significant effect on nutrient uptake. The highest uptake of Nitrogen, Phosphorus, and Potash by pumpkin vine was recorded maximum in the treatment 50 kg N, 25 kg P2O5, 25 kg K2O ha^-1 dose of fertilizers in combination with FYM 25 t ha^-1 and seed treatment with PSB 25 g kg^-1 of seed. i.e. T4. Available Nitrogen, Phosphorus and Potash in the soil after harvest of pumpkin crop were highest in the treatment with application of inorganic fertilizers 50 kg N, 25 kg P₂O₅, 25 kg K₂O ha^-1 in combination with FYM 25 t ha^-1 and seed treatment with PSB 25 g kg^-1 of seed. i.e. T₄ recorded maximum Nitrogen, Phosphorus, Potash (190.23, 27.97, 386.91 kg ha^-1 respectively).
