Abstract:

Under hot arid conditions, date palms are facing environmental stresses that limit tree productivity and negatively affect fruit quality characteristics especially weight and size. Bagging is a physical technique commonly used with many crops to protect the fruits from diseases, pests and to improve the micro-environment in which the fruits develop its ripening. This research was conducted during 2011 and 2012 seasons. Different materials of bagging were used to investigate its effect on fruit set, yield and quality of 11 years old ‘Rothana’ semi-dry date palm. Bunches were pollinated by placing 10 ‘Meghal’ fresh male strands among female clusters during both seasons. Two bagging materials (paper kraft and grill cloth) were performed after pollination for one month, besides without bagging as control. All the bagging treatments improved fruit quality with respect to fruit set, bunch weight, fresh fruit weight, fruit flesh weight, total and reducing sugars contents except fruit dimensions as compared to the control treatment. Between bagging treatments, T₃ (grill cloth) produced the best results in physical and chemical properties under study condition. Such results could be obtained either by bagging with grill cloth or with paper kraft per palm. Generally, bagging with grill cloth application treatment could be recommended to improve the bunch yield and fruit quality of ‘Rothana’ fruits under the current study conditions.
