“…Soil pH ≤5.5 or known as acid soil will produce high Al availability and is toxic to plants [5] and causes deficiency of macronutrients such as P, Ca, and Mg [6]. Application of lime and phosphate fertilization is another alternative to overcome soil acidity [7], but it requires an additional production cost which is not small and is often faced with the availability of materials. Research objectives are to find and utilize soybean germ plasma sources that are tolerant of soil acidity needs to be developed.…”

This study aims to determine the growth response of the vegetative stadia of three soybean varieties which are widely used in East Java on acid soils that have been given biological fertilizers from various Trichoderma isolates. The experiment was arranged factorially using a completely randomized design. The first factor was the variety consisting of Detam 3, Detam 4, Gema, Dering 1, and Burangrang. The second factor was Trichoderma isolates formulated as bio fertilizers, consisting of Tc-Jjr-02, Tc-Pjn-01, and Tc-Jro-01. Overall this experiment has 60 experimental units. Data were analyzed by variance analysis (ANOVA) followed by an honest significant difference test at the level of 5%. The results showed that there was no interaction between soybean varieties and Trichoderma isolates formulated in bio fertilizer. Soybean varieties significantly affected plant height, wet weight, and dry weight of roots and stover at 21 days after planting. The Burangrang variety shows the best growing ability in acid soils. There was no interaction between soybean varieties and Trichoderma bio fertilizers. Trichoderma isolate Tc-Jjr-02 increased the wet weight and dry weight of the roots and roots by 48.2 and 54.5%, respectively, and 38.9 and 48.2% compared to without Trichoderma. Trichoderma application maintains soil acidity between pH 4.50-4.67.
