Abstract
2 Abstract: The present study was carried out during the two successive seasons of 2006 -2007 and 2007-2008 in a private orchard located at Cairo - Alexandria desert road 50 Km., to study the effect of deficit irrigation th at specific phonological stages on vegetative growth, flowering, yield, quality of olive fruit and physiological status of 'Manzanillo' olive trees under drip irrigation system. Results showed that vegetative growth parameters (shoot length, leaves density and leaf area), yield, fruit weight and physiological measurements (percentage of opening stomata, leaf water potential and transpiration rate) responded negatively to the regime water treatments. Trees irrigated with 100% Etc. through along season (control) recorded the highest values, followed in descending order by those irrigated with 66% Etc. in all stages of experiment either harvest: inflorescence emergence or inflorescence emergence: pit hardening or pit hardening: harvest stages which produced an intermediate values. On the contrary, trees irrigated with 33% Etc. in stage of the experiment pit hardening: harvest were the lowest in this respect in both seasons. As for the flowering parameters (No. of total flowers/ inflorescence, sex ratio and length of inflorescence), in addition fruit set, it was found that trees irrigated with 100% Etc. through along season (control) recorded the highest values, following by 66% Etc. and 33% Etc. at pit hardening: harvest stage, followed in a descending order by those irrigated with 66% Etc. and 33% Etc. at harvest: inflorescence emergence stage which produced an intermediate values, while, trees irrigated with 66% Etc. and 33% Etc. at inflorescence emergence: pit hardening stage were the lowest in this respect in both seasons. Whereas the yield and fruit weight the data showed that the trees irrigated with 33% at inflorescence emergence: pit hardening recorded the lowest values while the trees irrigated with 33% at pit hardening: harvest recorded the lowest values of fruit weight. Thus it can decrease the irrigation water quantities to 66%Etc. at the stage from harvest to inflorescence emergence. While at the stage of inflorescence emergence: pit hardening and from pit hardening: harvest not allow decreasing the irrigation water quantities.
