Effect of the Combination of Biofertilizer and N, P, K Fertilizer on C-Organic Content, Total Bacteria, Humic Acid, and Sweet Corn Results in Jatinangor Inceptisols

Beneficial microorganisms are found in biofertilizers, which can assist boosting the soil's availability of N, P, and K promote plant growth. This study aims to ascertain impact optimal combination biofertilizer fertilizers for sweet corn yields, total bacteria, humic acid, C-organic yields. With 1 control treatment, 2 doses fertilizer, 6 combinations fertilizer biofertilizer, method used Randomized Completely Block Design (RCBD). Three times each, treatment was given. The findings indicated that significantly differed with organic C, Combining increased acid by 1.08%, 124.67x107, 2.74%, respectively. a dose liquid ¾ fertilizers, be grown up 11,80 kg plot-1, 59% increase over suggested amount fertilizer. result this showed best yields were obtained ½ biofertilizer.
