Shaban Kh. A., Wafaa A. Hafez and Faten A. Al-Kamar ( 2012). Effect of some soil amendments on soil fertility and tomato productivity under saline soil conditionMinufiya J. Agric. Res. Vol.37 No. 4:
Abstract: Field experiment was conducted in two summer growing seasons; of 2010 and 2011 in a private Farm, Gelbana Village 7. This area locate at east of the Suez Canal, at North Sinai Governorate, Egypt. The irrigation source is from, El - Salam Canal (1: 1 Nile water mixed with agricultural daring water). The objective of this work is to evaluate the best one of three soil amendments added (gypsum, sulfur and compost) and the best rate of application on soil fertility and yield of tomato (Super Strain B) variety under saline conditions of newly reclaimed soil. The results were as follows: the addition of gypsum, compost and sulfur led to reduce soil salinity and soil pH and increase production of tomatoes per feddan in the second season than first season. The productivity ranged from 4.986 to 24.819 Mega grams per feddan for the gypsum treatment and 4.988 to 27.430 for the sulfur treatment, as well as 4.989 to 27.694 Mega grams per feddan of the compost treatment. On the other hand the soil treated with all soil amendments led to increasing the content of the macro and microelements in the fruits of tomato. The soil treated with all soil amendments led to increasing the content of the macro and microelements available in soil .From the results of the study it can be recommend using the compost at a rate of 5 tons per fed to give an economic crop and get on the fertility of the soil suitable for the production of a good tomato yield.
