Abstarct: sustainable agriculture is a biological phenomenon that is trying to do the key features of a natural ecosystem. The aim on this research is improving and increasing fertility of the soil, biological control of the pests and decreasing of the chemical fertilizers use. In this way, an experiment was done in accordance with the effect of the 0, 3 and 6 ton in hectare vermicompost in some of the quantitative characteristics of two types of tomatoes and also the effect of Entomopathogenic fungus, (mextarhizium anisopliae) on tomato cutworm (Agrotis segatum). The experiment was conducted in Shahrood University Research farm as a split plot factorial baxsed on completely randomized blocks design in 3 replications in 1388. The main factor was tomato types including 2 types (al) PS and local type of shahrood (a2) and the sub factor contained composition 2 factors of M.anisopliae with two levels of s1, control (not using the fungi) and s2 the use of Entomopathogenic fungi with 3 levels of the vermicompost including c1, control (not using the vermicompost) c2 using 3 tons each hectare and c3 the use of 6 tons in each hectare. The characteristics that are related to the growth and function like shoot dry weight, tomato's function and also the amount of damage of the named pestilence on the tomato plants were recorded. The results of this study showed that the most amount of shoot dry weight relating to the local variety and the most function was observed in the PS variete. The fungus treatment had no significant effect on the decrease of the damage of cutworm . The use of the vermicompost levels has effect on the improving the plant growth in the life time growth of the plant. Vermicompost in the final harvest resulted increase of the fruit function in contrast with the experiment in two varieties. The most effect on the fruit function of tomato has been achieved from using 6 tons in hectare vermicompost.
