Impact of Seasonal Variation on Physico-Chemical Properties of Orchard Soil and their Relationship with Different Fruit Tree Species under Semiarid Irrigated Conditions

The chemical properties in the rhizosphere of fruit tree species were investigated during different season at CCS HAU, Hisar. Results revels that pH value, OC, N, P, K, Zn contents increased significantly with all the fruit orchards over control (uncultivated land). However, maximum pH, EC, OC, CN ratio, available N, P, K, Zn and Fe (8.30, 0.33 dS/m, 0.54 %, 11.63, 126.26 kg/ha, 32.24 kg/ha, 284.93 kg/ha, 2.10 ppm and 3.34 ppm) was found in aonla, sweet orange, jamun, jamun, guava, sweet orange, guava, ber and sweet orange, respectively. Highest EC, CEC, OC and available K were found in winter season but pH, EC, available N, Zn, Mn and B contents were recorded maximum in summer season.CN ratio and available P were maximum in rainy season. Inter row spaces soil had highest pH, CEC, CN ratio and Zn contents while maximum OC, Available N, P, K, Fe, Mn and B contents was observed under the canopy of fruit trees.
