Sudrajat, I. S., Zamroni & Arnanto, D. (2025). Effect of biosaka dose combine with plant growth promoting rhizobacteria on growth and yield of rice plants in Bantul Regency Indonesia. Bulg. J. Agric. Sci., 31(4), 709–717
The aim of this study is to see the effect of biosaka combination with plant growth promoting rhizobacteria on the growth and yield of rice plants (Oryza sativa L.) IPB 3S variety. This research was carried out at the self-help agricultural and rural training center “Lestari Makmur”, Semampir Hamlet, Argorejo Village, Sedayu District, Bantul Regency, Yogyakarta, Indonesia. The research was carried out using a single factor, namely biosaka dose, which was arranged in a complete randomized block design consisting of 4 replications. Each replication consisted of 5 treatments, so that 20 experimental units were obtained, namely without biosaka (K0); 43 l/ha (K1); 54 l/ha (K2); 64 l/ha (K3); 86 l/ha (K4). Observation variables included: plant height; number of tillers;dry weight of prunning; number of panicles; length of panicles; percentage of grain content; weight of 1,000 grains and weight of grain per hectare. The data obtained were analyzed statistically using ANOVA source of diversity analysis, and if a real effect was obtained, a further test was carried out using the Duncan multiple range test with a level of 5%. Based on the results of the analysis, the biosaka treatment dose of 43 l/ha gave the highest plant height, but there was no noticeable difference with other growth components. Biosaka dose treatment of 64 l/ha gives the highest number of tillers, number of panicles and weight of grain per hectare.
