Analysis of Factors Influencing Rice Yield and Prices in Iringa Irrigation Schemes

This study examines data from rice farmers across seven irrigation schemes in Iringa, Tanzania, to identify main factors influencing rice yield (in tons per hectare) and selling prices (in TZS per 100 kg). Descriptive statistics show notable differences: Luganga has the highest average yield (6.23 t/ha), while Idodi has the lowest (2.55 t/ha). Correlation analysis demonstrates strong positive relationships between yield and infrastructure quality (r = 0.95) and between yield and leadership quality (r = 0.94). Multiple linear regression confirms that infrastructure quality is a significant positive predictor of yield, though multicollinearity warrants caution in interpretation. Participation in scheme activities and access to credit are positively associated with prices, highlighting the importance of institutional factors in market performance. The findings stress the need for improved infrastructure and leadership to increase rice productivity, with policy implications for sub-Saharan African agriculture.
