Effect of Soil conditioners and Irrigation Levels on Growth and Productivity of Pomegranate Trees in the New Reclaimed Region

Abstract

ABSTRACT3 /tree /year gave similar effect on improving all growth characters, fruit set, yield and fruit quality except fruit diameter and V.C. Similar results were found with high rate of the mixture (2Kg NF+500gm K 2 SO 4 ) with the same level of irrigation on all characters except acidity. Date also indicated that the application of Hz soil combined with mixture of (NF+K 2 SO 4 ) at both highest levels for each of them and irrigated with moderate irrigation level 8.25m 3 /tree /year gave best growth and produced higher fruit quality as compared with trees irrigated with 100% from recommended water level. Similar effects of combinations between high rate of both Hundz soil and the mixture of Nilefertile + K 2 SO 4 under least irrigation treatments 5.5 m 3 /tree/year on the previous characters of fruit. Data indicated generally that the best treatment combination was gained from using highest irrigation level (11m 3 /tree /year) and 10Kg /tree Hundz soil + 2Kg /tree Nile Fertile + 500gm K 2 SO 4 which resulted in the highest values for all vegetative growth characters, leaf N P K, chlorophyll and RWC, yield and all fruit quality except leaf proline, juice tannins and acidity in both seasons. It could be recommended to apply 2Kg /tree Hundz soil combined with 2Kg NF + 500 gm K 2 SO 4 with irrigation level of 11m 3 /tree /year to obtain highest production with good quality of pomegranate fruits as well as to apply 2Kg /tree Hundz soil with 2Kg NF + 500 K 2 SO 4 under irrigation 8.25m3 /tree /year or 5.5m 3 /tree /year for saving about 25% -50% of water to achieve the same yield and fruit quality according to the availability of water, especially in the new reclaimed area.
