Influence of Irrigation Water Type, Dap And Max-gro on Vegetative Growth And Leaf Nutrient Content of Plum Trees (prunus Spp.) Cv. Samarra

This research was conducted in the growing season at an orchard Faculty of Agricultural Engineering Sciences Summel district Duhok governorate (Kurdistan region- Iraq) (2022) to examine effects basin irrigation, DAP supply, and Max-Gro foliar spray, fish irrigation on vegetative development leaf nutritional content three-year-old plum trees cv.Samarra. The experiment included three factors, first one is type water (fish Tap water), second factor soil supply with fertilizer (N 18% P 46%) (0, 50 100 g/tree) third spray concentrations organic liquid 2 4 ml. L-1). experimental units were set up as a split-split plots using factorial (2*3*3) Randomized Complete Block Design (RCBD). Here summary findings: features enhanced by (Single Leaf area (cm2 /plant),Increment stem diameter (cm), Increment number secondary branches ,Number leaves per branch, dry matter (%),of water. application significantly increased all studied parameters (increased area, shoot number, length, diameter, branches, branch) well nutrients applications Maxi-Gro
