Effect of soil properties on wheat varieties under open and eucalyptus based agroforestry system

Agroforestry Research Centre (old site) near Horticulture Research Centre, Patharchatta of Govind Ballabh Pant University of Agriculture and Technology, Pantnagar, U.S. Nagar. To study the effect of wheat varieties on soil properties under open and Eucalyptus based agroforestry system. The experiment was laid out in Randomized Block Design with two growing conditions (open and Eucalyptus based system) and four varieties of wheat viz., WH-711, UP-2565, PBW-343, and PBW-17 with three replication in each condition. Soil pH varied significantly under both farming system at 0-15cm depth and non significant at 15-30cm depth. The higher soil pH was observed in plots under PBW-343 at a depth of 0-15cm and 15–30cm. Soil pH is observed higher under Eucalyptus based agroforestry system as compared to open farming system. Soil EC varied non significantly under both farming system at 0-15cm depth and significant at 15–30cm depth. The higher soil EC was observed in plots under PBW- 343 variety. Soil EC is observed higher under Eucalyptus based agroforestry system as compared to open farming system. Soil organic carbon (%) varied non significantly under both farming system. The higher soil organic carbon was observed in plots under PBW-343 variety. Soil organic carbon is observed higher under Eucalyptus based agroforestry system as compared to open farming system. Available soil nitrogen was not influenced significantly under both farming system. Maximum soil nitrogen was observed in plots under WH-711 variety. Available soil nitrogen is observed higher under Eucalyptus based agroforestry system as compared to open farming system. Available soil phosphorus was not influenced significantly under both farming system. Maximum soil phosphorus was observed in plots under PBW-343 variety. Available soil phosphorus is observed higher under Eucalyptus based agroforestry system as compared to open farming system. Available soil potassium was influenced not significantly under both farming system. Maximum soil potassium was observed in plots under PBW-343 variety. Available soil potassium is observed higher under Eucalyptus based agroforestry system as compared to open farming system.
