| Abstract | ||||
| This study was carried out during 2014 & 2015 seasons on Washington navel orange trees 20-years-old, in research orchard situated at Baramoun, Mansoura region, Dakahlia governorate. Aiming to evaluate the effect of different weed control methods and their relationship to the growth, yield and fruit quality of Washington navel orange trees. Four weed control methods were tested, control, hand resistance, mechanical hoeing and three herbicides (Herphosate, Sting, Roal). The obtained results indicated that all used treatments significantly increased shoot length, number of leaves, leaf surface area and yield (kg) /tree, ton/feddan. The highest values of fruit weight and the lowest value of acidity % were found under chemical weed control (Roal), where, rind thickness, TSS% and vitamin C were not affected by any type of herbicides used. Also, chemical weed control (Roal) was increased leaf chemical composition (N, P, K, Fe, Zn and Mn). In addition, chemical herbicides (Roal) was the lowest costs in this respect. | ||||
