“…Symptoms of armyworm attack found during the planting period of sweet corn were randomly perforated leaves. This pest can cause up to 85% damage to corn plants and even crop failure [19]. Control of this pest attack is done manually (technically) by taking caterpillars that are in the leaves and stems.…”

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.

Inceptisols are often used for intensive cultivation and have low levels of essential nutrients. Improvement of this fertility rate can be achieved by the application of organic based fertilizers that can increase soil fertility. Peanut has long been cultivated in Indonesia and is generally grown on dry land. This research was conducted from February to June 2023, at the experimental garden, Padjadjaran University. This research aims to determine the effect of liquid organic fertilizer combined with standard NPK fertilizer on soil N total, plant nutrient uptake, and peanut yields in Inceptisol Jatinangor. This study used a randomized block design experimental method with nine treatments and three replications, and the amount is 27 experimental units. The result shows that the combination of liquid organic fertilizer with NPK fertilizer can enhance yields of peanuts. The combination of 10 liters of liquid organic fertilizer per hectare andb ¾ dose of Urea, TSP and KCl can increase the total-N content of the soil, the absorption of N, P, and K, as well as the weight of dried pods. Therefore, the use of liquid organic fertilizer in peanut cultivation can be reduced by up to 25% and can increase the yield of peanut pods.
