Impact of acidity of irrigation water, method of runners produce and chemical fertilizer on some vegetative growth characteristics of strawberry (CV. festival)

The experiment was carried out during the season 2020-2021 to assess the influence of three factors. The strawberry seedlings sources means that method of propagation of strawberry seedlings produced by plant tissue culture (T1) and runners (T2); Acidity of Water Irrigation treatments with three levels, without adding citric acid (C1) (the comparison), with a acidity irrigation water of pH = 6.5( C1) and a acidity irrigation water of pH = 5.5(C2), reducing the degree of its reaction using citric acid and the chemical fertilizer with five combinations, it is without chemical fertilizer (F0), the full recommendation of the fertilizer with macroelements (F1) (full batch), half of the fertilizer recommendation with macroelements (F2) (half batch), the entire recommendation of the fertilizer with microelements (F3) (full batch) and half of the fertilizer recommendation with microelements (F4) (half batch) on the vegetative growth of strawberry Fastival cultivar. The experiment was designed as a Randomized Complete Block Design (RCBD), and the GenStat program used least significant difference (LSD) at range test for mean comparison at a 5% probability level. The results indicate:the method of propagation of strawberry seedlings did not have any significant effect on the studied traits; While reducing the Acidity Irrigation Water (pH) to 6.5 and 5.5 led to a significant increase in the studied traits of the strawberry plant, the highest rate of vegetative characteristics was recorded at the interaction degree of irrigation water 5.5, including the number of leaves 32.22 leaves. plant −1, chlorophyll content 250 mg. 100 gm fresh weight −1, and Average total leaf area of the plant 1414 cm. plant −1. On the other hand, the chemical fertilization with macroelements according to the fertilizer recommendation had a significant increase in the characteristics of vegetative growth represented by the characteristics of average number of leaves, chlorophyll content and total leaf area of the plant and, which gave 42.75 leaves. plant −1, 277.5 mg, 100 g fresh mass −1, 1850.7 cm 2. plant −1, respectively. The treatment of the triple interaction of propagation of strawberry seedlings using runners produced by plant tissue culture tissue culture factors with irrigation water with Acidity Irrigation Water of 5.5 and chemical fertilization with macroelements was superior to the fertilizer recommendation and gave the highest results leaf area of the plant. While the highest signi
