| Abstract | ||
| This study was carried out on Zaghloul date palms grown at fruit Orchard of Faculty of agriculture, Assiut University during 2003 and 2004 season. In order to improve physical and chemical characters of fruits through soil drench applications of active dry yeast (10, 20 or 30 g/palm) and effective microorganisms solution (EM1, 0.5, 1.0 or 1.5 cm3/1L/palm) at Hababouk stage of fruit (four weeks after pollination). Twenty one palms were chosed and pollinated with a known male palm throughout the two seasons, where 3 replicates, one palm each, using complete randomized block design (CRB). The selected palms were treated with the abovementioned treatments for determining bunch weight, fruit retention %, physical and chemical characteristics of fruits in response to yeast and EM1 applications. The obtained results of this study could be summarized as follow. All treatments with yeast or EM1 improved bunch weight, physical and chemical characteristics of dates. The middle rate of both yeast (20 g/palm) or EM1 (1.0 cm3/1L/palm) gave the best results of bunch weight with the best fruit quality of Zaghloul date palms. On going back to the previously results, it could be concluded that either active dry yeast at 20 g or EM1 (1.0 cm3/L)/palm soil drench application four weeks after pollination for obtaining high yield with good fruit quality under the conditions of this study. | ||
