PENGARUH PEMBERIAN BERBAGAI JENIS MIKROBA TERHADAP PROSES PEMBIBITAN HASIL AKLIMATISASI TANAMAN PISANG CAVENDISH (Musa acuminata)

In general, the productivity of bananas developed by the community is still quite low. Commercial banana development still faces many obstacles, one of which is the difficulty of obtaining superior seeds in large quantities, at affordable prices and on time. This problem in the nursery aspect needs to be addressed immediately so that banana cultivation can be optimal. Biological microbes are preparations made from active living organisms that bind certain nutrients or facilitate the availability of nutrients in the soil for plants. The aim of this research is to determine the effect of using various types of microbes on the cultivation of Cavendish banana plants resulting from in vitro culture. This research was carried out for 4 months starting from August 2021- February 2022 at the Screen House of the University of Muhammadiyah Malang and the Experimental Land on Jalan Baiduri Tlogomas. The method used is a combination of various types of bacteria in the growth of banana plants, namely B1 (Positive Control), B2 (Negative Control), B3 (S1T110-4(1)), B4 (S1T1 10-4(2)), B5 (S1T2 10-4(1)), B6 (S1T4 10-5), B7 (S1T2 106(1)), B8 (S1T4 10-3(1)), B9 (S1T6 10-3(1)), B10 (S1T4 10-4(3)). In this experiment, 10 treatments were given, 3 replications, and 3 samples for each treatment so that 90 research samples were obtained. The variables observed were plant height, number of leaves, leaf length, leaf width, stem diameter, leaf color, root length, number of roots, temperature of the planting medium, and pH of the planting medium. The application of various types of bacteria to each Cavendish banana plant growth showed that treatment B9 (S1T6 10-3(1)) had a significant effect on plant height, number of leaves, leaf length, leaf width, stem diameter, root length and number of roots, and shows good dark green leaf color results.
