The use of marginal dry land is one strategy to overcome the limited soil fertility. Indonesia has marginal dry land of around 102.8 million ha, most of which are podsolite red yellow (PRY) or Ultisol whose distribution reaches 45.794.000 ha or about 25% of the total land area in Indonesia. This study aims to determine the characteristics yield of soybean after being treatment with bokashi fertilizer and mycorrhiza fungi on marginal dry land. This study was used the randomized block design in factorial pattern consisting of 2 factors i.e., doses of bokashi fertilizer consisting of 4 levels, without fertilizer (S0), bokashi fertilizer 5 t ha–1 (S1), bokashi fertilizer 10 t ha–1 (S2), bokashi fertilizer 15 t ha–1 (S3) and second factor is arbuscular mycorrhiza fungi (AMF) consisting of 4 levels, without AMF (M0), AMF 5 g/planting hole (M1), AMF 10 g/planting hole (M2), AMF 15 g/planting holes (M3). The parameters observed: Number of pods, number of seed/plants, weight of 1000 seeds and production (t ha–1). The results showed that the combination of bokashi fertilizer with the AMF had an effect on the number of pods and seeds number/planting. The highest soybean yield was obtained in a combination of bokashi fertilizer at doses 15 t ha–1 and AMF 15 g/planting hole (S3M3) as 1.59 t ha–1. The combination of bokashi fertilizer at doses 15 t ha–1 with AMF 15 g/planting hole gave the highest yield as 1.59 t ha–1. |
