      abstract = {Biochar is an important material for soil mineral supply  and amendment. Root nodule formation in leguminous plants  is also stimulated by biochar. Biochar contains carbon  which can be used as an energy source by microbes and  contains pores which are suitable for microbial habitat,  and it temporarily increases activity of free-living  nitrogen-fixing bacteria. Coconut shell biochar can be used  as an ameliorant, but the use of single coconut shell  biochar can cause a problem such as the use of high dose  that will lead into high cost. One of the solutions to  solve the problem is to improved coconut shell biochar into  formulated biochar (FB) by managing the composition and  enrich it with chemical fertilizer’s such as dolomite,  organic fertilizer compost of sugarcane bagasse and guano.  Mixture of formulated biochar (FB) gave better results than  single biochar alone on black soybean. When this FB is  applied in the field, it can make efficient use of an  organic fertilizers in increasing grain yields. This  research was conducted to determine the effect of  Formulated Biochar (FB) on nodule production, dry matter  and productivity of black soybean seeds. The study was  conducted for one season in an experiment field in Winaya  Mukti University, Sumedang-Indonesia at 850 m above sea  level (m ASL). Detam I seed cultivar was used because it  has a wide adaptability in Indonesia and has high nutrient  composition and yield potential.  The experiment was  arranged in a randomized block design consisting of 5  treatment doses of FB (0, 0.5, 1.0, 1.5, 2.0 tons ha-1) and  replicated 5 times. The responses observed were the number  of effective nodules, growth characteristics, production  components and productivity of black soybeans. The results  showed that the application of FB had a significant effect  on increasing the effectiveness of nodule production, dry  matter, and productivity of black soybean seeds. The  formulated biochar dose of 2.0 tons ha-1 increased the  effectiveness of nodule production up to 100% and 44.87% of  soybean productivity, while the formulated biochar dose of  1.5 tons ha-1 increased soybean productivity by 38.46%  compared to the control. It is therefore concluded that  formulated biochar as soil conditioner and soil booster  could be used to improve the growth and grain yield of  black soybean.},
