The study aimed to see how cow manure and NPK Pearls fertilizer affect the growth and yield of white pumpkins. They tested different levels of each fertilizer on the plants in East Kalimantan. Cow manure didn't affect plant height much, but it did increase fruit yield. NPK Pearls fertilizer made the plants taller, but didn't change fruit weight. When used together, the two fertilizers didn't have a big impact on plant height or fruit weight.
