The Effect of Planting Distance and Mycorrhizal Biofertilizer on the Growth of Red Beans (Phaseulus vulgari SL)

Abstract

Red beans are a type of vegetable bean that bears fruit and is very rich in protein content. The purpose of this study was to determine the effect of planting distance and mycorrhizal biofertilizer doses on the growth and production of red beans. The study was conducted in agricultural land from October to November 2023. The design used for this study was a randomized block design (RAK) factorial pattern consisting of 2 factors, namely factor 1, namely planting distance (J), namely J1 = Planting distance 30 x 20 cm, J2 = Planting distance 50 x 20 cm, J3 = Planting distance 50 x 30 cm. Factor 2 is biofertilizer (H), namely H0 = control, H1 = Biofertilizer 10 g plant-1, H2 = Biofertilizer 20 g plant-1, H3 = Biofertilizer 30 g plant-1. The results of the study showed that the treatment of planting distance of 50 x 20 cm and the dose of biological fertilizer of 20 g plant-1 (J2H2) had a very significant effect on the growth and yield of red bean plants, the treatment of planting distance of 50 x 20 cm and the dose of biological fertilizer of 20 g plant-1 (J2H2) produced the length of red beans, the interaction between the treatment of planting distance of 50 x 20 cm and the dose of biological fertilizer of 20 g plant-1 gave the best results of red bean plants.
