Abstract
Two field experiments were carried out during 2004 and 2005 growing seasons in the Experimental station in Wadi Sudr area, South Sinai, Egypt. The objective of this study was to assess the effect of irrigation intervals, composting organic fertilization (0, 10, 20, and 30 m3/fed., feddan = 0.42 hectare) on the growth of three varieties of sorghum, namely Giza5, Giza13 and Giza18. The obtained results showed that organic fertilization results in decreasing the saturated hydraulic conductivity, increasing soil aggregate stability and decreasing soil penetration resistance. In this respect short irrigation intervals were superior to the long irrigation intervals on their impact on soil physical properties, i.e. in reducing soil mechanical strength and increasing the soil aggregates, especially those resist wind erosion. Also, the data showed that increasing organic fertilization up to 30 m3/fed has resulted in increasing yield of sorghum varieties and its components particularly under the short irrigation intervals. In all cases, the highest yield was obtained with variety Giza18 as compared with Giza13 and Giza8. Therefore, it could be concluded that Giza 18 sorghum variety was more adapted under saline conditions of South Sinai region. Raising the application rates of organic fertilization from zero up to 30 m3/fed caused gradual increase in growth and yield components through 1st and 2nd cuts of the studied varieties. The study concluded that the maximum yield of sorghum can be obtained upon using the variety Giza18 and 30 m3/fed. organic fertilization under short irrigation intervals
