Abstract

In order to evaluate the effect of combining orchard management practices with efficient irrigation systems on increasing yield in almond orchards, an experiment was conducted in split plots with randomized block design and three replications at almond station of the Agricultural and Natural Resources Research and Education Center of Chaharmahal and Bakhtiari province. The main plots included orchard management and the subplots included full irrigation treatment, supplying water at 100% of the estimated water requirement at all growth stages, and low irrigation treatment (supplying water at only 50% of the estimated water requirement for irrigation). The cultivar used in this project was Shahrood 12, grafted onto GN rootstock. After the treatment, growth, reproductive, physiological traits and nutrient concentrations were measured in the seedlings under study. The results showed that the morphological traits of tree crown length and width, branch length and diameter, and leaf length and width were affected by low irrigation and this treatment reduced all of the above factors. Also, low irrigation treatment reduced fruit length and diameter and function. Also, low irrigation treatment caused a decrease in the concentration of copper, zinc, iron, manganese, phosphorus, and an increase in potassium in the leaves. Also, low water caused an increase in leaf proline and a decrease in leaf water.
