PENGARUH PERTUMBUHAN DAN PRODUKSI BEBERAPA VARIETAS TANAMAN KACANG PANJANG (Vigna sinensis L.) DENGAN PERLAKUAN BIANG BAKTERI AKAR BAMBU

Bamboo root bacteria consist of pseudomonas and Bacillus polymixa bacteria, which can bind or fix nitrogen from nature. This study aims to determine the effect of the concentration of bamboo root bacteria on several varieties of long bean plants and the interaction between the concentration of bamboo root bacteria and types on the growth and production of long beans. This research was conducted from May 2022 to July at the Faculty of Agriculture, Fisheries and Animal Husbandry. Nineteen November University Kolaka. This study used a Randomized Block Design (RAK). The first factor is the long bean variety, which consists of 3 levels, namely V1 = Canton Tavi variety, V2 = Parade Tavi variety, and V3 = Pertiwi variety. The second factor was the concentration of bamboo root bacteria concentration treatment consisting of 3 levels, namely K0 = control, K1 = 5 ml/liter of water, and K2 = 7 ml/liter of water. This study consisted of 9 treatments, three replications, and 27 experimental units. The data were analyzed using analysis of variance and then continued with Duncan's test. The result of the research showed that the best long bean variety was Kanton Tavi (V1), and the best bacterial source concentration for long bean growth is 10 ml/liter air (K2), which was shown in the characteristics of plant length, number of leaves, number of pods per plant, and length of pods per plant. There was no interaction effect between the concentration of bamboo root bacteria and variety on all observed long bean growth and yield variables. The concentration of bacterial pathogens and types significantly affected the variables leaf length, number of leaves, 50% flowering age, number of pods per plant, and size of pods per plant.
