Agricultural inputs on rice yield: A case study of domestic rice production in Preah Vihear province, Cambodia

The key factors affecting domestic rice production in Preah Vihear Province, Cambodia, are investigated in this study. Cambodia’s economy depends largely on rice, which is both a main food and a major export. It helps Cambodia’s economy and food security. However, rice production is difficult due to lack of water, small farms, and geographical problems. Preah Vihear province is a key rice-producing region with hills and small farms. It helps increase income and sell rice to other countries with unique and famous rice seeds. To analyze the factors affecting domestic rice production in Preah Vihear, a statistical model known as ordinary least squares (OLS) will be used to examine the relationship between various input variables (costs) and rice yield. Data were gathered from a sample of 51 rice-farming households across five villages in Preah Vihear province. Additionally, both regression models indicated that herbicide costs were the most significant factor affecting rice yield, demonstrating high significance at the 5% level. This was closely followed by the price for renting rice harvesters and the total land area for rice production (ton). This study provides crucial information that can be used to develop targeted strategies to increase rice production and enhance the livelihoods of rural farmers. This will also empower stakeholders in the agricultural sector to propose campaigns that promote sustainable rice cultivation in local communities.
