High yielding and disease resistant plantain and banana hybrids and its associated technologies generated by IITA to combat the menace of black Sigatoka disease (Mycosphaerella fijiensis) were massively disseminated in year 2000. Since the hybrids were slightly different from the existing varieti...

Sustained adoption of soil carbon enhancing practices (SCEPs) at scale remains an aspiration goal to maintain sufficient amount of soil carbon in household farms in order to impact on the sustained farm productivity caused by sustained soil fertility. The objective of this study is to systematica...

This article examines the impact that misreporting adoption status has on the identification and estimation of causal effects on productivity. In particular, by comparing measurement error-ridden self-reported adoption data with measurement-error-free DNA-fingerprinted adoption data, we investiga...

Cassava is an important food security crop among smallholder farmers in Southern Nigeria, because it can tolerate drought, low soil fertility and its production requires minimum external inputs. In most African countries, cassava is becoming important cash crop that has high potential for use as ...

This paper examines the welfare impacts of improved groundnut varieties in eastern Zambia using data from a survey of over 600 households. We use the stratification-multilevel, matching-smoothing, and smoothing-differencing methods to analyse how treatment effects vary with the propensity to adop...

This paper examines the impacts of access to extension services and cooperative membership on technology adoption, asset ownership and poverty using household-level data from rural Nigeria. Using different matching techniques and endogenous switching regression approach, we find that both extensi...

BACKGROUND In southern Africa, conservation agriculture (CA) has received a lot of research and promotional support from various organizations in the past decades. Conservation agriculture is largely promoted as one of the few win–win technologies affordable to farmers, in the sense that potentia...
