Its early maturity and drought resistance allows mungbean to be cultivated on upland with dry climate. Approriate cultivation technology need to be identified in order to increase productivity. The research objective was to formulate cultivation technology package by assessing interaction between plant population, optimum organic and anorganic fertilizers on mungbean. This experiment was conducted on upland Alfisol soil with type E climate in Probolinggo, East Java on dry season 2015, using split plot design, with three replications. As the main plot was plant spacing, namely: 1) 40 cm x 10 cm, 1 plant/hole, 2) 40 cm x 15 cm, 2 plants/hole, and 3) 40 cm x 20 cm, 2 plants/hole. As the sub plot was combination of organic and anorganic fertilizers, namely: 1) without fertilizer, 2) 50 kg ZA + 50 kg SP36 + 100 kg KCl/ha, 3) 150 kg Phonska/ha, 4) 5 ton manure/ha, and 5) 75 kg Phonska + 2,5 ton manure/ha. Medium dose of NPK fertilizer (22,5 kg N + 22,5 kg P2O5 + 22,5 kg K2O + 15 kg S) per ha and plant population of 250.000 until 333.333 plant per ha, was considered suitable to grow mungbean at upland with dry climates, based on the obtained yield. While low dose of NPK fertilizer (11,3 kg N + 11,3 kg P2O5 + 11,3 kg K2O + 7,5 kg S) plus 2.500 kg manure/ha was capable of producing high biomass of mungbean up to 3,2 kg/ha.
