This study investigated the relationship between soil quality and the growth of Black Taro (Colocasia esculenta) amended with chicken manure and cow manure at WichienmatuSchool. The objectives were to (1) compare soil quality resulting from the application of chicken and cow manure, (2) compare the growth of Black Taro in both soil conditions and (3) examine the correlation between soil quality and plant growth under these amendments.
The results indicated that soil amended with cow manure exhibited higher acidity than soil treated with chicken manure. Conversely, the chicken manure treatment showed significantly higher soil moisture and higher levels of essential macronutrients (nitrogen, phosphorus, and potassium). These differences directly influenced the development of the Black Taro, suggesting that manure type plays a critical role in enhancing soil properties. The findings conclude that chicken manure is more effective than cow manure in improving soil fertility and promoting the growth of Black Taro in the study area.
