EVALUATION OF DIFFERENT FLOODING IRRIGATION METHODS IN VALENCIA ORANGE ORCHARDS UNDER KAFR EL-SHEIKH CONDITIONS
A field experiment was carried out during two successive growing seasons (2000 and 2001) to evaluate the different flooding irrigation methods (Basin, Ring-shaped, Basin furrow and Border strip irrigation) of “Valencia” orange orchards under Kafr El-Sheikh conditions.
The obtained results indicated that, tree vegetative growth as indexed by shoot length and number, leaf area, dry weigh and dry weight percent, tree height, canopy width, trunk diameter, and trunk cross sectional area (cm2) and canopy volume (m3/ tree), was larger on trees irrigated with border strip irrigation method than those of trees irrigated with Basin or other irrigation methods.
Moreover, trees irrigated with border strip irrigation method had the greatest fruit yield (71.47 and 68.32 kg/tree/year) and tree yield efficiency (fruit weight 3.11 and 2.83 kg/m3 of canopy or yield per TCSA 1.62 and 1.53 kg/cm2) than those of trees irrigated with Basin or other irrigation methods. also, these trees gave the highest fruit number/ tree compared with other irrigation methods.
The highest values of fruit weight, total soluble solids percentage (TSS%), TSS / acid ratio, and the lowest value of acidity % was found under Border strip irrig. method compared to the other treatments. However, vitamin C content and peel thickness were not significantly affected by different irrigation methods.
Leaf N, Ca and Mg contents were slightly affected by different flooding irrigation methods. Meanwhile, leaf P, K, Fe, Mn and Zn contents were significantly affected by adopted method, and the highest average values of the previous elements were found under Border strip irrigation method.
Thus, it could be concluded that Border strip irrigation method was the better method for Valencia orange orchard under Kafr El-Sheikh conditions.
