The effect of vermicompost on growth characteristics of tomato

Disposal of large quantities of animal waste is becoming a serious and costly environmental problem. Recently, research programs have been initiated in using earthworm to break down organic wastes. Vermicompost which is resulted from earthworm to break down organic wastes. Vermicompost which is resulted from earthworm activities on organic wastes is an important and valuable source or plant nutrients. The aim of present work was to determine the effects of vermicompost on the growth characteristics of tomato under greenhouse conditions. The effects of three levels of chemical fertilizer and five levels or vermicompost on root and shoot growth, fruit weight and the number of tomato were investigated. The results showed that chemical fertilizer and vermicompost had a significant effect of root and fruit weight and number of tomatoes. In 11)11% vermicompost treatment, fruit weight and fruit number, shoot and root weight were respectively three, four, five and nine times more than control treatment. The effect of vermicompost application was much higher on root than shoot growth, the results also showed that the enriched vermicompost with the highest level of fertilizer led to a greater root and shoot weight. The vermicompost by fertilizer interaction had no significant effect on fruit number. However, fruit weight as well as root and shoot growth were significantly affected such an interaction.
