The development of soybeans in coastal sand area besides using adaptive cultivars also requires the input of organic matter to increase its productivity. One source of organic material that has not been widely used is banana stem. The research aimed to study: 1) the characteristics of banana stems bokashi and its role to improving the growth and yield of some soybean cultivars, and 2) Response growth and yield of soybean cultivars at the level of banana stem bokashi in the coastal sands. The research is a laboratory and field experiment conducted for 6 months from October 2016 until March 2017. Pot experiments in the field have been done in Samas coastal sands, Srigading Village, Sanden Sub-district, Bantul Regency, special Region of Yogyakarta. The factorial experiment (4 × 12) was repeated 3 times, arranged in a complete randomized block design (RCBD). The first factor was dose banana stem bokashi including 0, 20, 40, and 60 t.ha-1; was tested on 12 soybean cultivars namely Anjasmoro, Argomulyo, Burangrang, Demas 1, Dena 1, Devon 1, Gamasugen 1, Gema, Gepak Ijo, Grobogan, Kaba, and Slamet. The observational data were analyzed by the variant analysis of the error rate of 5% and if significantly different was followed by DMRT 5% error level. The results showed that bokashi made from banana stem has chemical composition which can be used as a soil conditioner and as organic fertilizer. Soybean cultivars respond to various doses of bokashi given. In general, soybean cultivars increased growth and yield of seeds in bokashi application to optimum dosage, and did not increase again with higher doses. However, there are also soy cultivars that are not responsive or even depressed growth and yield of seeds when given bokashi banana stem.
