Abstract: Effects of growth medium rates on the growth, productivity and fruit quality in two varieties of tomato were in greenhouse. Six treatments were imposed using different combination with vermicompost (VC), rice husk ash (RHS) and coconut fiber (CF): Control – T1 (0% VC + 50% RHS + 50% CF), T2 (20%VC + 40% RHS + 40% CF), T3 (40% VC + 30% RHS + 30% CF), T4 (60%VC + 20% RHS +20% CF), T5 (80% VC + 10% RHS +10% CF), and T6 (100% VC). Growth and yield parameters were recorded at 100 days after transplanting. The results demonstrated that: 1) Addition of VC increased plant height and stem diameter significantly, but it had no significant effects on the numbers of leaves; 2) The yield of tomatoes were significantly higher when the proportion among VC, RHS and CF was 60% VC + 20% RHS + 20% CF (T4) or 80% VC + 10% RHS + 10% CF (T5); 3) Moreover, addition of VC also decreased fruit pH, titratable acidity and increased soluble solids in tomato fruits compared to those harvested from plants cultivated in controlled treatments; and 4) In conclusion, VC as a medium supplement has increased tomato yield, soluble solids, and vitamin C concentration.
