<![CDATA[Research on the effect of plant distance and mulch on yield of crop soybean (Glycine max, L. Merrill) Var. Grobogan conducted in November 2016 to January 2017. The study in the village Kembangkuning, District Windusari, Magelang. Altitude of 440 m above sea level, with latosol soil type and soil pH of 6.5.

The second factor was plant distance, the plant distance of 40 cm x 10 cm, 40 cm x 20 cm and 40 cm x 30 cm. Silver black plastic mulch increased plant height, the number of productive branches per plant, weight of 1.000 dry seeds, stover dry weight per plant and dry seed weight per m2. The plant distance of 40 cm x 30 cm increased the number of productive branches per plant, weight of 1.000 dry seeds and stover dry weight per plant.
