Abstarct: For investigating of the effect of bio and organic muck on the quality and quantity of the essence of medical plant Thymus.vulgaris , a test with 16 attendances and 3 repeti-tions , in a factorial manner in a random complete blocks design cast in the agricultural year 1388-1389 in the research farm of Sari university jehad was operated . The test at-tendances included of first factor : chemical muck with 2 levels ( a0: not consuming , a1 : consuming baxsed on the local custom )that baxsed on this , 100 kilogram in hectares Ni-trogen , 50 kilogram in hectares phosphor and 50 kilogram in hectares potassium were used . The second factor : Nitroxin muck at 2 levels included b0: not consuming , b1 : consuming baxsed on the directed baxse ). The third factor was Vermi compost at 4 lev-els ( c0 : not consuming , c1 : 2 tons in hectares , 4 tons in hectares , 6 tons in hectares Vermi compost). Using of chemical much , Vermi compost muck and Nitroxin muck was meaningful on the features of the height of bush , wet weight , dry weight and the performance of essence , but there was not a meaningful difference among the reciprocal effects on the investigated features . The results obtained from the test showed that the performance of essence in the grown bushes in the condition of consuming of Nitroxin muck relative to it`s not consuming increased 5.30%, consuming of chemical muck caused the increase of 13.8 percent of essence operation in comparision of it`s not con-suming , the results showed that in relative to the essence operation , a meaningful dif-ference was not seen between the levels of 2 and 4 with 6 tons Vermi compost .But consuming of 6 tons in hectares Vermi compost muck in comparison of it`s consuming increased the essence operation 28.87 percent . The maximum amount of Timol in the condition of combination of chemical muck with 6 tons Vermi compost in hectares ( 57.25%) was observed and the lowest amount of Timol was related to the consuming of 2 tons Vermi compost in hectares ( 42.49%) .
