Résumé
This study was initiated during 2000 and 2001 seasons on sewy date palms grown under EL-kharaga oasis, new valley governorate. This study aimed to throw some lights on the effect of varying bunch/leaves ratio on the yield as well as physical and chemical properties of sewy dates. This experiment included five treatments from bunch/ leaves ratio namely 1:4, 1:6 1:8, 1 ;10 and 1:12 each treatments replicated three times one palm per each. For evaluation the effect of the five bunch/ leaves ratio the following characters were measured during both seasons. 1-Number of bunches/palm 2-yield (kg) per palm 3-Bunch weight (kg) 4-fruit weight (g) 5-seasons changes in fruit dimensions (in2000 season) 6-fruit volume (CC) 7-specific gravity 8- fruit dimensions (height and diameter) 9- fruit shape index value 10-percentages of pulp 11- percentages of seeds 12- percentages of total soluble solids 13- percentages of total and reducing sugars 14- percentages of sucrose 15- percentages of total acidity
