This study aimed to compare soil quality and the growth of butterfly pea plants under different manure treatments, including cow manure, chicken manure, and a mixture of cow and chicken manure. The objectives were to examine changes in soil quality and to compare the growth of butterfly pea plants cultivated with each type of manure. The experiment was conducted by measuring soil moisture, soil pH, and macronutrient levels, including nitrogen, phosphorus, and potassium (NPK), which are important factors affecting plant growth. The results showed that different manure treatments had various effects on soil quality and plant growth. Butterfly pea plants grown in soil amended with mixed manure and chicken manure exhibited better and more consistent height growth compared to those grown with cow manure alone. Soil quality analysis indicated that manure application helped adjust soil pH to a suitable range (approximately 6–7), which is optimal for butterfly pea growth. In addition, the levels of essential nutrients such as nitrogen, phosphorus, and potassium increased, supporting chlorophyll production and stem development. Environmental factors such as soil moisture and light intensity also influenced plant growth. Proper moisture control enhanced nutrient absorption from manure, contributing to healthier plant development. Overall, the study demonstrates that appropriate manure types and ratios can improve soil quality and promote the growth of butterfly pea plants.
