Abstract

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

8 of 9 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.

Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
