| Abstract | ||
| This study was carried out during two consecutive seasons (2011 and 2012) on sewy date palm cultivar growing at the experimental orchard of Faculty of Agriculture, Assiut University. The effect of some organic (Elobore compost) and biofertilization of N (nitrobin) compared to inorganic N fertilization (ammonium sulphate) on some vegetative growth characteristics, yield as will as some physical and chemical fruit properties was studied. Results showed that use organic N fertilizer either alone or combined with inorganic N fertilizer or biofertilizer significantly increased Leaf length ,Leaflets area, No. of Leaflets and No. of new leaves compared to using inorganic-N fertilizer alone. This increment was insignificant with Leaf area. Yield components (initial fruit set, horticultural fruit set, bunch weight and total yield) were significantly increased by using organic N fertilizer either alone or combined with inorganic-N fertilizer or biofertilizer, in most cases. The best treatment that gave the highest values of yield parameters when using 100% N organic fertilizer treatment compared to the other treatments. The highest values of fruit weight, size, diameter, flesh weight, total soluble solids and sugars were obtained by using 100% N-organic fertilization treatment compared for the other investigated treatments, especially inorganic N fertilization. | ||
