Abstract:
A field experiment was conducted to assess the effect of integrated nutrient management on some physical properties of soil in wheat (Triticum aestivum L.) crop on Mollisols of Uttarakhand under poplar based agroforestry at Agroforestry Research Centre (old site), Patharchatta of G.B. Pant University of Agriculture and Technology, Pantnagar during rabi seasons of 2017-19. The experiment was laid in Randomized Complete Block Design comprising of nine nutrient treatments (chemical fertilizers and its substitution with organics) replicated thrice. Bulk density was recorded minimum under T₅ (1.31 Mg m^-3) management while it was recorded high with soil depth and with control treatments. Owing to a negative relationship between bulk density and water holding capacity, T₅ subsequently had significantly maximum values of both soil water holding capacity (72.1%) as well as hydraulic conductivity (0.74 cm hr^-1) in 0-15 cm soil layer. Usage of organic sources with fertilizers improved the physical properties of soil after two years of continuous nutrient application.
