Abstract

Black soybean (Glycine max (L.) Merr.) is a soybean plant having typical morphology; it is its black shell seed. Though it has similar morphology and nutrition to yellow soybean, black soybean has specifically usage as the ingredient of soy sauce. One of the obstacles in soybeans cultivation, especially black soybean, is rust disease by Phakopsora pachyrhizi. An eco-friendly alternative in controlling leaves rust disease uses resistant varieties and biological control agent of Plant Growth Promoting Rhizobacteri (PGPR) and Corynebacterium (Coryne). This research aims to examine the effectivity of PGPR and Coryne giving toward the rust disease intensity on black soybeans varieties in rust disease endemic lands. This research uses completely randomized design of two factors (factor 1 black soybean varieties; V1: Detam 1, V2:Detam 3, V3: Detam 4 and factor 2 biological control agents; control, PGPR, and Coryne). This research applies 9 combinations and three times of repetitions. The observed parameters covers rust disease intensity, the height of plant, the diameter of plant canopy, the diameter of stem, the number of seeds per plant, the number of pods per plant, the weight of seeds per plant, the weight of 100 seeds per plant. F test is applied in statistics analysis. If it shows significant effect, Duncan Multiple Range Test of 95% trust level would be applied later. The results shows that the soybeans varieties gives significant effect toward the weight of seed per plant and gives very significant effect on the weight of 100 seeds per plant whereas biological control agent treatment gives significant effect on the height of plant and the number of seeds per plant moreover it gives very significant effect on rust disease intensity and the weight of 100 seeds per plant. Both factors do not show an interaction on all the observed parameters. The comparison between PGPR application and control toward rust disease intensity shows 8.9% PGPR, Corynebacterium 11.7%, and 33.9 % of control.
