This research aimed to study the effect of soil quality on the growth of spring onions in two areas: Ban Khin Nak and Ban Hai Yai, Sisaket Province. The study focused on comparing soil properties such as pH, moisture, and nutrient fertility to assess the relationship between soil quality and spring onion growth.
Soil samples were collected in equal quantities from both areas. Data on spring onion growth, including height, number of leaves, and growth rate, were collected over a 20-day observation period. The data was then analyzed and compared to determine the optimal soil quality for spring onion cultivation.
The results showed that the soil in Ban Khin Nak had a pH range more suitable for spring onion growth than the soil in Ban Hai Yai. Furthermore, it had higher levels of major nutrients such as nitrogen, phosphorus, and potassium, resulting in better spring onion growth in Ban Khin Nak.
