The effect of soil conditioner and growth booster on the agronomic characters and number of nodules of black soybean

Soil Conditioner & Growth Booster (SCGB) is a potion that was made to be used as a soil
conditioner and plant growth promoter. SCGB is made from organic matter, biological fertilizers, soil
ameliorants, and microelements. This research aims to determine the best dosage of SCGB on the
agronomic characters, effective nodules, and black soybean variety ‘Detam-1’ yield. This research was
conducted in the experimental field of the Faculty of Agriculture, Winaya Mukti University,
Sumedang, Indonesia. This experiment used a simple randomized block design (RBD) with six
treatments (0, 3, 6, 9, 12, 15 kg/ha) and repeated 4 times. The observation was conducted on a number
of effective root nodules, plant height, number of leaves, 100-grain weight, number of pods, seed
weight per plant, and seed weight per plot. The result showed that SCGB application significantly
improved agronomic characteristics of black soybean plants, increasing the number of effective
nodules by 147% to 168% compared to untreated plants. A dose of 3 kg/ha SCGB showed the best
results in increasing 35% on yield seed weight per hectare compared to without application of SCGB.
