An investigation of factors that influence the technical efficiency of soybean production in the Guinea savannas of Nigeria por Amaza, P., Ogundari, K.

“…A stochastic frontier production function, using maximum likelihood estimation (MLE) technique was applied in the analysis of data collected in 2006 from a sample of 182 soybean farmers in the guinea savannas of Borno State, Nigeria. The MLE results revealed that farm size, seeds, family labour, hired labour and fertilizer were the major factors that were associated with change in the output of soybeans and were significant (p = 0.05). …”
