The intercropping system and integrated fertilizers were applied in the research to improve land efficiency and the quality of sweet corn and vegetable soybean crops. The study was conducted in the Giwangan Village of Umbulharjo Yogyakarta, Indonesia, and was set up using a three-replication factorial Randomized Complete Block Design. Three organic fertilizer sources (cow manure, chicken manure, and composted waste) made up the first factor, and the second factor was NPK fertilizer doses (200, 300, and 400 kg ha^-1). Two control treatments were also made, which resulted in 33 experimental plots. The observed data were subjected to analysis of variance and Duncan’s Multiple Range Test at a significance of 5%. The study’s findings demonstrated that the combination of 300–400 kg ha^–1 NPK fertilizer and chicken manure increased variables such as the content of vitamin C and pro-vitamin A, number of seed rows, number of 2-3 seed pods, and sweetness level of soybean and sweet corn, as well as the land equivalent ratio, land equivalent coefficient, competition index, system productivity index, and relative yield mixture.
