Abstract

The purpose of this research was to determine vegetative growth performance of Morus alba and Arachis pintoi with different percentages of compost mixture (rabbit feces and kepok banana (Musa paradisiaca Linn) peels) and soil as media. The materials used was 72 Morus alba stacks, rabbit faeces, kepok banana peels, and Azotobacter culture as decomposer. This research was conducted by Completely Randomized Design with 4 treatments and 6 replications. The treatments were T₀ (100% soil), T₁ (20% of compost and 80% of soil), T₂ (40% of compost and 60% of soil), and T₃ (60% of compost and 40% of soil). The data was analysed using analysis of variance, followed by Duncan’s Multiple Range Test (DMRT) if the results are significantly different. The treatment gave higher leaves number, roots weight, and roots length (P<0.05) in Morus alba. Same also on plant length, branches number and wet weight (P<0.05) of Arachis pintoi. The conclusion of this research is that the application of organic compost based on rabbit manure and banana peel with Azotobacter microbial culture decomposer can improve the growth performance of Morus alba and Arachis pintoi. The best level was T₁ with 20% of compost and 80% of soil.
