The Sumenep people adore the composite local corn of the Guluk-guluk variety (Zea mays saccharata Sturt) variety. Only 182,581.43 tons of corn are produced annually, for an average productivity of around 1.097 tons per hectare. Local corn var. is one variety of local corn that is grown by many Sumenep farmers. rumble. The typical amount of local maize that yields According to Sugiarti and Hayati (2009), the productivity of guluk-guluk is 3.5 tons/ha lower than that of superior corn varieties, which range from 4.5 to 5.7 tons/hectare. The amount of fertility, the amount of rain, and the use of less-than-ideal production inputs are the root causes of the low productivity. Applying balanced fertilization, which combines organic and inorganic fertilizers, is one way to boost production. This study means to dissect the communication and impact of the blend of natural compost and NPK manure on the development and yield of neighborhood maize of the Guluk assortment composite. The examination configuration utilized a randomized block plan (RBD) comprising of 2 variables with 3 replications. The elements tried comprised of: doses of NPK fertilizer (zero, 350, and 700 kg/ha) and organic fertilizer (zero, 500, and 1000 kg/ha). A 5% level of analysis of variance was used to analyze the data. A second Duncan's test at a level of 5% is carried out if there is a significant effect. At 14 HST, there was no interaction between the application of organic fertilizer and NPK for the plant height variable; however, there was an interaction at 30 HST, 45 HST, and 60 HST. The interaction between the application of organic fertilizer and NPK fertilizer was reflected in the cob length, cob weight per plant, and cob weight per plot variables. The mix of medicines A3B2 (natural manure 1000 kg/ha + NPK compost 350 kg/ha) and A3B3 (natural manure 1000 kg/ha + NPK compost 700 kg/ha) gave the best impact on the variable cob weight per plant, cob weight per plot, cob length, and plant level.
