Abstract
Soil solarization of furrow-irrigated soils in Egypt effectively controlled weeds, broomrape, corky root, and root-knot diseases in tomatoes. It also controlled Rotylenchulus reniformis for 60 days after planting. It improved plant growth and increased the yields by 25-432% in broad beans, onions, tomatoes, and clover in various types of soils. In one experiment with broad beans, Rhizobium nodulation was adversely affected by solarization, and the plants were stunted but later recovered. Solarization had a long-term effect (two or three seasons) in both disease control and yield increase. It also decreased soil salinity.
