Sweet corn ( Zea mays saccharata Sturt.) is such a popular commodity that it has good market opportunities. Increase productivity of sweet corn, necessary through improving its physical, chemical, and fertility properties. Continuous use of inorganic fertilizers can reduce soil fertility. Biofertilizer is an alternative to improve and enhance soil quality to increase growth and increase plant’s yield and quality significantly. The study aimed to determine the effect of biofertilizers’ application on the growth and yield of sweet corn on the upland. The research was conducted in 2016 in Tapin district, South Kalimantan Province. It is using a randomized block design with four treatments and eight replications. The treatments consisted of Po without biofertilizer + NPK fertilizer at a dose of 100%, P1 biofertilizer + NPK fertilizer at a dose of 100%, P2 biofertilizer + NPK fertilizer at a dose of 75%, P3, biofertilizer + NPK fertilizer at a dose of 50 %. The variables observed were plant height, cob weight with husk, cob weight without husk, cob diameter, cob length, number of seed columns, and production. The results showed that applying biofertilizer increase cob weight and sweet corn production.
