PEMBERIAN PLANT GROWTH PROMOTING RHIZOBACTERIA (PGPR) TERHADAP PERTUMBUHAN DAN HASIL TANAMAN KACANG HIJAU (Vigna radiata L.)

Abstract

Increasing mung bean production can be done by improving technical culture such as the use of organic and biological materials. The use of PGPR bacteria in increasing plant growth and crop yields is one of the sustainable agricultural alternatives. The research design consisted of 5 levels where each treatment was repeated 5 times and each repeat there were 3 plant samples so that the number of plants used was 75 plants. This study used the RAK pattern including the level of PGPR administration. The level of treatment carried out is P₀ (without PGPR); P₁ (PGPR 4.5 ml.l^-1 water); P₂ (PGPR 9.0 ml.l^-1 water); P₃ (PGPR 13.5 ml.l^-1 water) and P₄ (PGPR 18.0 ml.l^-1 water) with variables observed in this study were plant height, number of leaves, number of pods, and weight of 100 seeds. The treatment of PGPR affects plant height, number of leaves, number of pods and weight of 100 seeds of green bean plants with the best dose is 18.0 ml l^-1 water.
