| This study investigates the impact of soil properties on technical efficiency in paddy production, focusing on Malaysia’s two main paddy granaries: KADA and IADA BLS. These granaries play a significant role in Malaysia’s paddy production. The research employed three different models, with productivity as the dependent variable. In models 1 and 2, standard physical inputs were used as independent variables. Model 3, however, augmented the inputs with the addition of soil property variables. The stochastic frontier model was analysed using the maximum likelihood estimation method. The empirical results revealed significant impacts from fertiliser, pesticide and land inputs, with the exception of land in model 1, where its coefficient was not statistically significant. Additionally, soil pH and the calcium+magnesium/potassium ratio emerged as crucial factors affecting paddy productivity. Importantly, incorporating soil property variables into the analysis resulted in a relatively lower technical in-efficiency estimate. These insights are invaluable for policy formulation, highlighting key inputs that can optimise paddy production. The study’s findings regarding soil properties are particularly relevant for refining strategies in national paddy develop-ment programs, emphasising the importance of sustainable soil management. Looking ahead, the study advocates for comprehensive technical efficiency estimations that account for all forms of heterogeneity, including weather conditions, to ensure more accurate and insightful assessments. |
