“…However, there is little rigorous empirical evidence to support this notion. While various studies have explored the yield response of fertilizer in crop production, (Adedeji et al, 2014, Sommer et al, 2013, Omonona et al, 2012, Offodile et al, 2010, Akighir and Shabu, 2011, Xu et al, 2009), there are few studies that have actually explored the profitability of fertilizer use. Moreover, most studies on profitability are either outdated or largely based on case study areas––not nationally representative (Wopereis-Pura et al, 2002, Poussin et al, 2003, Becker and Johnson, 1999, Adedeji et al, 2014, Omonona et al, 2012).…”

“…While various studies have explored the yield response of fertilizer in crop production, very few address the fact that there are likely unobserved characteristics that affect fertilizer application rates that also affect yields1 (Offodile et al, 2010, Akighir and Shabu, 2011, Adedeji et al, 2014). This paper uses the LSMS-ISA with plot level information to provide empirical evidence on the profitability of fertilizer use for maize production across Nigeria, addressing the endogeneity of the input use decision.…”

Inorganic fertilizer use across Sub-Saharan Africa is generally considered to be low. Yet, the notion that fertilizer use is too low is predicated on the assumption that it is profitable to use rates higher than currently observed. There is, however, limited empirical evidence to support this. Using a nationally representative panel dataset, this paper empirically estimates the profitability of fertilizer use for maize production in Nigeria. We find that fertilizer use in Nigeria is not as low as conventional wisdom suggests. Low marginal physical product and high transportation costs significantly reduce the profitability of fertilizer use. Apart from reduced transportation costs, other constraints such as soil quality, timely access to the product, and availability of complementary inputs such as improved seeds, irrigation and credit, as well as good management practices are also necessary for sustained agricultural productivity improvements.

“…Considerable attention by previous studies in Tanzania focused mostly on technical efficiency (Mkanthama et al, 2018) and yield response to fertilizer application but few of them addressed the likelihood of some unobserved characteristics that may affect both fertilizer application and yield leaving allocative efficiency with little consideration (Adedeji et al, 2014;Mhoro et al, 2015). To my knowledge, only one study by Mather et al (2016) estimated the profitability of inorganic fertilizer use in smallholder maize production in Tanzania and another study by Sheahan et al (2013) for the case of maize in Kenya.…”

Is Increasing Input Use for Rice Production a Profitable Proposition in Tanzania?

Demand for food staples particularly rice has been increasing tremendously especially in Sub-Saharan Africa relative to supply attributed by a continued rise in population. The shortfall in supply is generally considered to be caused by low use of inputs particularly inorganic fertilizer and improved seed among others. Meanwhile, there is limited empirical evidence to support this notion. This paper aimed at estimating the profitability and yield response to inorganic fertilizer and improved rice seed using cross-section data collected from 256 smallholder rice farmers in Mbarali district-Tanzania. Data was analysed using treatment effect model while instrumental variable was used for robustness check. Results shows that inorganic fertilizer use in the study area is not low as generalized by previous studies. It was further revealed that increasing fertilizer and seed use by 1 kg leads to an increase in yield by 6.2 kgha-1 and 9.2 kgha-1 respectively. Furthermore, rice production is a profitable business though low marginal physical product and high fertilizer price significantly reduce the profitability of fertilizer use. Thus, reducing input costs through well-managed subsidy programs, timely accessibility of inputs coupled with irrigation facilities and good agronomic practices are crucial for sustainable and profitable agricultural development.
