PENGARUH KONSENTRASI PUPUK ORGANIK CAIR TERHADAP PERTUMBUHAN DAN HASIL TIGA VARIETAS KACANG HIJAU (Vigna radiata L.)

Abstract

Green beans (Vigna radiata L.) are leguminous plants that play an important role in the agricultural system and food security in Indonesia. This study aims to determine the effect of liquid organic fertilizer (POC) on the growth and yield of three varieties of green bean plants (Vigna radiata L.). The study was conducted using a factorial Randomized Block Design (RBD) with two factors, namely POC concentration (0 ml/L, 10 ml/L, 15 ml/L, and 20 ml/L) and green bean variety (new variety, common variety, and transgenic variety), with three replications for each treatment combination. The observed parameters included plant height, leaf area, and pod count at various observation ages. The results showed that there was a significant interaction between POC concentration and variety on the growth and yield of the plants, especially in leaf area (68 and 86 days after planting) and pod count. The POC application generally increases all growth parameters compared to treatment without POC, with a concentration of 15 ml/L (P3) yielding the highest results. The transgenic varieties showed the best response to the POC application, characterized by a more significant increase in leaf area and pod number compared to other varieties. The combination of P3 treatment on transgenic varieties resulted in the highest average number of pods, indicating the effectiveness of this combination in enhancing yields. Thus, applying liquid organic fertilizer at optimal concentrations, specifically 15 ml/L, has the potential to improve growth and yields in mung bean plants. These findings support the use of POC as an environmentally friendly and sustainable alternative to organic fertilization in mung bean cultivation systems.
