For more information, please contact [email protected]. INFORMATION TO USERS This was produced from a copy of a document sent to us for microfilming. While tl most advanced technological means to photograph and reproduce this docume have been used, the quality is heavily dependent upon the quality of the mater submitted. The following explanation of techniques is provided to help you understai markings or notations which m'ay appear on this reproduction. 1.The sign or "target" for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting through an image and duplicating adjacent pages to assure you of complete continuity. 2. When an image on the film is obliterated with a round black mark it is an indication that the film inspector noticed either blurred copy because of movement during exposure, or duplicate copy. Unless we meant to delete copyrighted materials that should not have been filmed, you will find a good image of the page in the adjacent frame. If copyrighted materials were deleted you will find a target note listing the pages in the adjacent frame. 3. When a map, drawing or chart, etc., is part of the material being photo graphed the photographer has followed a definite method in "sectioning" the material. It is customary to begin filming at the upper left hand corner of a large sheet and to continue from left to right in equal sections with small overlaps, if necessary, sectioning is continued again—beginning below the first row and continuing on until complete. 4. For any illustrations that cannot be reproduced satisfactorily by xerography, photographic prints can be purchased at additional cost and tipped into y oui xerographic copy. Requests can be made to our Dissertations Customei Services Department. | § 5 5. Some pages in any document may have indistinct print. In all cases we have filmed the best available copy. - UniversiV Microfilms International 300 N.

About 33 percent of the Egyptian national income orig inates in the agricultural sector. On the other hand, around 50 percent of the Egyptian population is in the agricultural sector. The cultivated area in Egypt is about 5.64 million feddan.^ Further, it is usually cultivated three times a year.
