2) Treatment 2: 50% Basalt soil + 17,5% straw+ 17,5% Bagasse mud + 10% Peat + 5% Cow dung + probiotics AT Bio-Decomposer
3) Treatment 3: 50% Basalt soil + 17,5% straw+ 17,5% Bagasse mud + 10% Peat + 5% Cow dung + Trichoderma probiotic production
4) Treatment 4: 50% Basalt soil + 17,5% straw+ 17,5% Bagasse mud + 10% Peat + 5% Cow dung + EM probiotic production. The results showed that the substrates contented 50% Basalt soil + 17,5% straw+ 17,5 % Bagasse mud + 10% Peat + 5% Cow dung + Trichoderma (Formula CT3) probiotic product was suitable for the growth and development of rice seedling Thiên Ưu 8 variety to have the highest tolerability and good quality.
