Abstract

The effect of intercropping spacing on yield, fruit quality, and leaf chemical composition of Zebda mango trees grown among Zaghloul date palms at Rasheed region, EL-Behera Governorate, Egypt was studied to estimate a suitable intercropping spacing of mango trees on date palms. In general, Zebda mango trees grown at wide intercropping spacing (6×6 m.) produced the highest yield / tree, represented in increasing number of panicles / tree, number of flowers / panicle, number of fruits / tree and fruit retention % as compared with those at other intercropping spacing. In addition, wide intercropping systemsignificantly increased fruit quality, represented in fruit dimensions and weight of fruit and pulp with high content of TSS, non-reducing sugars and total sugars %. Likewise, it significantly increased leaf chlorophyll (a), (b), carbohydrates and some mineral content as N, P and K. Medium intercropping system (5×5 m.) produced middle values of the studied parameters followed by closed intercropping system (4×4 m.) which produced the lowest values in this respect.
On the other words, wide intercropping spacing was most suitable for Zebda mango trees grown among date palms, which came in the first class in yield and fruit quality as compared with other intercropping systems and it was similar in most parameters to those of control (traditional cultivation 5×5 m.) and could be as a recommended system under conditions of this study, consequently growers can stop substitution of date palms with mango trees to maximize their output of the limited cultivated lands in this region.
