The maize plants (Figure ) exhibited early maturity in maize B, followed by maize A, maize C, maize D, and maize E at the time of harvest as a characteristic difference in the nutrient composition ratios of the samples. The yield was high in Maize A with a total weight of 316.24 g (Table ) which was due to the addition of thiourea, followed by Maize C with a weight of 287.38 g and Maize B 173.17 g respectively. There was minimal difference between maize D and maize E with no signs of grains, indicating limited nutrient in both, possibly both were still in the developmental phase. However, the cob in maize E was slightly larger and taller compared to maize D. This is attributed to slow release of nutrients present in the rabbit manure E, along with insufficient nitrogen and phosphorus content as compared to A, B and C (Table ), as adequate nitrogen supply is crucial for optimal maize growth and yield potential. According to a study by, the application of nitrogen significantly increased the grain yield and biomass production of maize plants, alongside, phosphorus is crucial for root development, seedling growth, and flowering. Maize B, with the highest average plant height of 107.83±24 cm had average yield compared to maize A and maize C. Its maturity was faster compared to the other two, likely due to pH as it was still acidic at the time of application and the imbalance of nutrients, particularly nitrogen, although, potassium is crucial for the development of strong stems, roots, and maize cobs. Phosphorus is important for root development, seedling growth, and flowering, while nitrogen is essential for the growth and development of maize plants. It constitutes an important component of chlorophyll, the pigment responsible for photosynthesis, as well as amino acids, which serve as the building blocks of proteins. Consistent with the study by, the application of nitrogen significantly increased the grain yield of the maize plants. Maize A and maize C were nearly identical in size and yield, although maize A outperformed slightly due to higher nitrogen content obtained from thiourea and urea present in the NPK fertilizer.
