The paper uses panel data originated from two sessions of household surveys: a baseline survey conducted in 2008 and a follow up survey in 2010, in northern Tanzania. Using a flexible transcendental logarithmic (translog) production function, results showed that the productivity of pigeonpea is positively and significantly associated with the size of pigeonpea cultivated land, labor, interaction between plot size and seed quantity, and the interaction of seed use with time. The study also revealed that there was technological progress in pigeonpea production systems over the period of 2008 to 2010. Furthermore, results from elasticity analysis indicated that smallholder pigeonpea producers were experiencing increasing returns to scale, suggesting that output of pigeonpea could respond positively and with higher proportion for a given simultaneous percentage change in quantity of seed, manure and labor. Therefore, support for human capital formation of farmers and increased access to improved pigeonpea seed varieties could be important intervention areas to increase pigeonpea productivity in northern Tanzania. Moreover, farmers should also be encouraged to use more manure, seed and labor so as to increase pigeonpea production without expansion of land use.
