The Impact of Arbuscular Mycorrhizal Fungi and Planting Distance on Mung Bean Production (Vigna radiata L.)

This study aims to investigate the impact of arbuscular mycorrhizal fungi and plant spacing on the production of mung beans (Vigna radiata L.). This study employed a randomized block design (RBD) in a factorial pattern, consisting of two factors. The first factor is arbuscular mycorrhizal fungi (AMF) with four levels: expressly without AMF propagules (M0), 5 g AMF propagules/planting hole (M1), 10 g AMF propagules/planting hole (M2), and 15 g AMF propagules/planting hole (M3). The second factor is planting distance, consisting of three levels: a plant spacing of 40 cm x 10 cm (J1), a planting distance of 40 cm x 20 cm (J2), and a planting distance of 40 cm x 30 cm (J3). The treatment was repeated three times to obtain 36 experimental units. The variables observed were: number of flowers, total number of seeds, number of filled pods, number of empty pods, pod weight, seed weight, dry weight of 100 seeds, and productivity. The results showed that arbuscular mycorrhizal fungi and planting distance had a very significant effect on the total number of pods, number of filled pods, pod weight, seed weight, dry weight of 100 seeds, and productivity. The best treatment was obtained at 15 g AMF propagules/planting hole (M3) and a planting distance of 40 cm x 30 cm (J3).
