Fragmentation is a problem which has affective role on adoption of new agriculture technology Field experiments were conducted at Gihena, Sohag governorate in season 2008/2009 to study the effect of fragmentation on irrigation, area losses, some agriculture operation. This study has a major to improve the work establishment and crop management in fragmentation to increase the yield and quality. The total area at Gihena center Sohag governorate was 1062 faddan divided into 12 plots. The owners' fields were 1666 farmer, the average area for every farmer between less than 6 kerat and 72 kerat.
The data indicated that:
The percent of owners for every were, 24.79 %have area less than 6 kerat, 31.57% have area less than 11 kerat, 25.45% have area less than 23 kerat, 9.12% have area less than 35 kerat, 3.84% have area less than 47 kerat, 2.40% have area less than 59 kerat, 0.60% have area less than 71 kerat and 2.22% have area more than 72 kerat.
The area losses decreased by increasing field area, area losses were 13, 12.50 and 12 % for field area 24, 48 and 72 kerat respectively.
The irrigation water decreased by increasing field size for yields wheat, faba bean and clover, the quantity of irrigation water for wheat was decreased by 1.44, 3.61 and 7.12 % when the field size increased from 6 kerat to 24, 48, 72 kerat respectively.
The yields were affected by fields size, the yield of wheat per feddan increased by 6.82, 9.10 and 18.18 % when the field size increased from 6 kerat to 24, 48, 72 kerat respectively. Also the yield of faba bean had the same trend, the seed yield increased by 10.91, 20.00 and 23.64 % when the field size increased from 6 kerat to 24, 48, 72 kerat respectively. The weight of clover cuts per feddan increased by increasing the field size, (1 faddan = 4200m2 = 24 kerat , 1 kerat = 175m2 ).
