Abstract

Sweet corn (Zea mays saccharata Sturt.) is such a popular commodity that has good market opportunities. To increase the productivity of sweet corn, it^s necessary to improve 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 so as to significantly increase growth and increase yield and quality of plants. The aim of study was to determine the effect of application of biofertilizers on the growth and yield of sweet corn on upland. The research was conducted in 2016 in Tapin district, South Kalimantan Province. Using a randomized block design with 4 treatments and 8 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 withhusk, 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.

Keywords: fertilizer, soil fertility
