Abstract

This study was conducted to evaluate the response of "Le-Conte" pear trees budded on Pyrus communis pear rootstock under different irrigation rates and humic acid applications. Irrigation rate (IR) reduction declined some growth parameters (shoot length, shoot diameter, number of leaves/shoot and leaf area), percentage of burnt spurs (as fire blight symptoms), fruit yield per tree and per feddan, yield income value/tree, fruit weight and size as well as fruit dimensions especially with least IR (14.3 m3/ tree/ year). On the other hand, IR decrease, markedly increased fruit firmness, fruit juice TSS, TSS/acid ratio and number of fruits in one kg. Also, IR reduction partly increased percentage of fruit set, number of fruits/tree and water use efficiency (WUE). Since, the highest WUE (3.85 kg pear fruits from each m3 irrigation water) could be obtained from 16.7 m3/tree/year (2810.6 m3/feddan/year) irrigation rate. Humic acid applications (especially 50 ml in 1L of water/tree as soil treatment every other week during the growing season) significantly enhanced the growth parameters, fruit set, fruit characters, yield components, yield income value and water use efficiency while decreased the percentage of burnt spurs, fruit firmness and number of fruits in one kg.
