Effect of Bag Placement, Fungal Inoculation of Roots, and Different Levels of Irrigation on Growth and Pomological Characteristics of Peach in Split Root Culture

Improving water use efficiency in horticultural crops can be achieved by adopting appropriate practices. An experiment was conducted to reduce water stress in Peach var red top grafted on GF677. The experiment was arranged in a factorial completely randomized design with three replications. The treatments consisted of bag placement beyond tree trunk (0, 1 and 2 bag/tree), irrigation rate (50, 75 and 100 % of field capacity) and fugues (0, Mycorrhiza and Trichoderma). The results indicated that the highest content of chlorophyll and fruit number were observed in 2 bag 100 irrigation and Trichoderma treatment which 18% was higher than that of control. The increased both trunk diameter and stem growth were achieved in the treatment 0 bag, 100 irrigation, Mycorrhiza, 1 bag, 75% irrigation and Trichoderma, respectively. Treatment 0 bag, 75% irrigation and 0 fungi had the highest content of total soluble solid (TSS) and TSS/Titratable acidity. In general, the treatment of 1 bag, 75% irrigation and Mycorrhiza led to increased growth, yield and quality of fruits.
