Relative Growth Rate (RGR) and Net Assimilation Rate (NAR) of Green Beans (Vigna radiata L.) with Combination of Organic Fertilizers in Ultisol Soil
Abstract
This study aimed to investigate the impact of the interaction between organic fertilizer on the Relative Growth Rate (RGR) and Net Assimilation Rate (NAR) of mung beans grown in Ultisol soil. The research was conducted in Pangkalan Kuras District, Pelalawan Regency, from July to October 2024. The experimental design was a factorial, completely randomized design (CRD) with two factors. The first factor consisted of different doses of bamboo leaf compost fertilizer (0, 50, 100, and 150 g/plant), while the second factor included various concentrations of tofu liquid waste POC (0, 25%, 50%, and 75%). Statistical analysis was performed using variance analysis followed by the Honest Real Difference Test (BNJ) at a significance level of 5%. The results indicated that the interaction between bamboo leaf compost fertilizer and tofu liquid waste POC significantly influenced the plants' relative growth rate and net assimilation rate. The most effective treatment was observed with 150 g/plant of bamboo leaf compost fertilizer combined with 75% concentration of tofu liquid waste. Furthermore, the main effect of bamboo leaf compost fertilizer was significant on RGR and NAR, with the optimal treatment being 150 g/plant. Similarly, the main effect of tofu liquid waste was significant on RGR and NAR, with the best treatment observed at a 75% concentration.
