A greenhouse experiment was conducted on a sandy soil in a randomize complete block design to study the effect of different addition methods and rates of algifert (as biofertilizer) on cucumber production and some soil properties.           The obtained data showed a pronounced increase in EC values than control. However, ESP decreased especially with soil together with foliar application. While pH values were not affected; OM and available N, P and K in the studied soil in all treatments of algifert were more than control.           With respect to cucumber plant growth and yield, it was found that soil and foliar application increased, plant dry weight, N, P, K content in cucumber leaves and  fruit yield significantly. Foliar and soil application (Treatment F) gave the highest plant growth and yield followed by C (0.1% foliar application) and D (0.2% foliar application) ones. The improvement of physical and chemical properties of the investigated sandy soil with algifert additions was the main factor to increase the plant growth and yield of cucumber.
