Dun'ng two successive seasons (2003 and 2004). field experiments were carried out to determine the long-term effects of soil solarization with application of organic and bio-fertilizers on maize (Zea mays L.) grown after faba bean. The results showed that the residual effect of solarization reduced significantly the number and dry weight of annuals weeds after 8 weeks from maize sowing compared with the non-solarized treatment. 0n the other hand. the number of perennial weeds significantly increased with solarization. while the dry weight of perennial weeds did not reach the significant effect. The residual effect of solarization and organic fertilizer improved growth of maize plants (plant height and number of leaves per plant) after 90 days from sowing. Solan'zation increased significantly number of maize earsfplant. Grain weight/plant. straw weightlplant, 1000-kernel weight. ear length, ea. diameter, ear weight and grains weight per ear.
