| Abstract | ||
| Present study was carried out on 7 years old Keitt mango trees budded on Succary rootstock, grown under drip irrigation in sandy soil orchard located at Wady EL-Natroon, EL-Behaira Governorate, Egypt during 2019 and 2020 seasons. Factorial experiment was conducted to investigate specific and interaction effects of tree shading with ceroon net combined with foliar spray of 9 N, P, K, Ca, Mg nutritive solutions on some growth, nutritional status, yield and fruit quality (physical & chemical properties) of Keitt mango cv.Data obtained revealed that, most evaluated parameters responded specifically to both studied factors (shading & foliar nutrition treatments). Hence, all growth parameters, leaf N, P, K%, yield (No. & weight), fruit physical (weight & pulp %) and fruit juice chemical properties (TSS, TSS/Acid ratio, total sugars and v.c) contents were increased by shading application. Moreover, all nutritive solutions improved the abovementioned parameters than control (water spray). However, both T9 (fertifeed Ca, Mg-COOH + fertifeed P, K-COOH) and T5 (Fertifeed phosphy-K COOH) and to great extent T7 (Carpox-K COOH + NH4NO3) were the superior. Accordingly, specific effect of each factor (shading & nutritive solutions) reflected certainly on their combinations whereas spraying shaded Keitt mango trees with T9 (fertifeed Ca, Mg-COOH plus fertifeed P, K-COOH) and / or T5 (Fertifeed P-K COOH) nutritive solutions exhibited statistically the greatest beneficial effects on their various evaluated growth, nutritional status, yield and fruit quality parameters. | ||
