An experiment was carried out to study the influence of rootstocks on plant volume, root growth, biomass, water relations and leaf nutrient status of almond cv. Non Pareil under different soil moisture regimes at the experimental farm of Department of Pomology, Dr. Y.S. Parmar University of Horticulture and Forestry, Nauni, Solan (H.P.). Almond plants cv. Non Pareil were raised on bitter almond and wild peach rootstocks and were subjected to different soil moisture regimes (-0.5, -2.5, -5.0 and -10.0 bar). The experiment was laid out in a factorial Randomized Block Design with three replications. Results obtained revealed that almond plants raised on wild peach rootstock had more plant volume (0.81 m3) than on bitter almond rootstock (0.70 m3). Plant volume was highest at less soil moisture stress (-0.5 bar) than at higher water stress. Root length and weight was more in plants raised on bitter almond rootstock (19.64 m and 67.93 g) than those raised on wild peach rootstock. Length and dry weight of roots was also higher in plants irrigated at -0.5 bar (22.82 m and 87.75 g) than those plants irrigated at higher soil moisture stress. Rate of photosynthesis was higher in plants raised on wild peach rootstock (14.48 µmol/m2/S) however stomatal conductance was higher in plants raised on bitter almond rootstock (0.48 mmol/m2/S). However these two parameters were more in plants maintained at -0.5 bar in comparison to plants maintained at higher soil moisture stresses. Leaf N, P and K contents were not significantly influenced by rootstocks however the contents were high under low soil moisture stress (-0.5 and -2.5 bar). Plants raised on bitter almond rootstock had less reduction in different parameters recorded at high soil moisture stresses (-5.0 and -10.0 bar) than the plants raised on wild peach rootstock thus can tolerate water stress better as compared to wild peach rootstock.
