The effect of organic fertilizer "Agerton" on the growth and yield of some tomato varieties in green houses

This search was carried out in Abi Garash farm, Faculty of Agriculture, Damascus University to study the efficiency of using “Agerton” as a fertiliser; either by irrigation or a foliar spry on tomato seedling. Four varieties were used (Astona, Tyrad, E26 and Local). Results showed that the treatment by the fertilizer resulted in an increase in growth thorough the plant length increasing. This increase was about 1.1 and 1.2 folds for all varieties and types of treatment (irrigation and foliar spry), as compared to the control. Moreover, the using of fertilizer led to a significant increase in the yield of plant, which increased by 1.2 and 1.5 in Astona; 1.2 and 1.4 in E26, 2.2 and 2.3 in Local and 1.5 and 2 in Tyrade, for the treatment of irrigation and foliar spry, respectively.
