Abstract:
A field experiment entitled “Effect of integrated nutrient management in pigeon pea (Cajanus cajan L.) based intercropping system” was conducted during the Kharif season of 2019-20 and 2020-21 at Agronomy Research Farm of Acharya Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya (U.P.), India to evaluate the effect of three intercropping systems (Pigeon pea sole, Pigeon pea+ sesamum and Pigeon pea+ sorghum) with five integrated nutrient management practices((N1-RDF alone, N2- RDF + FYM @5t ha-1, N3- RDF+FYM@5t ha-1 + sulphur@40 kg ha-1, N4- RDF + FYM @ 5t ha-1+ sulphur @ 40 kg ha-1 + ZnSo4 @ 25 kg ha-1 and N5- RDF+FYM @ 5t ha-1 + sulphur @ 40 kg ha-1 + ZnSo4@ 25 kg ha-1 + B@1.5 kg ha-1). On the basis of two year results, maximum reduction of bulk density (1.43 and 1.42 Mg m-3), soil pH (7.81 and 7.79), EC (0.33 and 0.31 dSm-1), was recorded in pigeon pea + sesamum intercropping as well as pigeon pea + sesamum intercropping system recorded maximum particle density (2.65 and 2.64 Mg m-3), organic carbon (0.34 and 0.36%). Pigeon pea sole was recorded maximum availability of Nitrogen (162.15 and 164.39 kg ha-1), available Phosphorus (16.45 and 17.62 kg ha-1), available Potash (242.27 and 244.51 kg ha-1), available sulphur (11.68 and 12.80 ppm) and DTPA extracted zinc (0.48 and 0.52 ppm) and boron (0.47 and 0.48 ppm) in respective years of 2019-20 and 2020-21. Among the integrated nutrient management practices, application of N5 (75% RDF + FYM@ 5t ha-1 + Sulphur@ 40 kg ha-1 + ZnSO4@ 25 kg ha-1 + Boron @ 1.5 kg ha-1) recorded maximum particle density (2.65 and 2.64 Mg m-3) and organic carbon (0.35 and 0.36%), available Nitrogen (162.82 and 165.06 kg ha-1), available Phosphorus (16.77 and 17.93 kg ha-1), available Potash (241.63 and 243.87 kg ha-1), available sulphur (12.78 and 13.90 ppm) and DTPA extractable zinc (0.52 and 0.54 ppm) and boron (0.54 and 0.56 ppm) and also recoded maximum reduction of bulk density (1.38 and 1.36 Mg m-3), soil pH (7.71 and 7.70), EC (0.29 and 0.28 dSm-1), respectively over RDF.
