Mungbean has good opportunities to develop in conditions of low light intensity like in the shade intercropped plants such as mungbean intercropped with corn. The limited of area of agricultural land causing the need for a more efficient way of farming to increase food production example intercropping. The study aims to get a organic fertilizer and fertilizer NPK is optimal to reach a good crop. The study was conducted in Dryland Field Laboratory Faculty of Agriculture, University of Sebelas Maret Surakarta, in sukosari, district Jumantono, Karanganyar regency from February to June 2013. The study was conducted using Randomized Completed Block Design (RAKL) one factor that fertilizer treatment consisted of one control, six standard and two comparators monoculture. The results showed that intercropping treatments P4 Organic fertilizer is 3200 kg/ha, urea 50 kg/ha, SP-36 fertilizer 32.32 kg/ha, KCL fertilizer 32.32 kg/ha tended to reach a good crop than the other treatment is 0.924 tons / ha (mungbean) and 1.987 tons / ha (corn). The analysis results also showed treatment P4 it was Organic fertilizers 3200 kg/ha, urea 50 kg/ha, SP-36 fertilizer 32.32 kg/ha, KCL fertilizer 32.32 kg/ha likely to produce the highest crop yield of Rp. 23.725.500.
