Abstract: The field experiment was conducted for four months, from December 2014 to April 2015, in the beach sand area of Samas Beach, Bantul, Yogyakarta. The research is conducted to observe the effect of planting density of mung bean and the planting time in intercropping with upland rice on the growth and yield of mung bean. The experiment consists of five treatments for the planting density of mung bean and two treatments for the planting time. Totally, there are 15 combinations of treatment with three replications prepared by using a split plot design (split plot). There has been a decline in mung bean production along with the decreasing of the density of mung bean in intercropping system with upland rice. P4 treatment shows the highest harvest in the intercropping treatments which is not significantly different from its monoculture, while the first planting shows the highest results of mung bean compared to the second planting time.
