- Adoption and impacts of conservation agriculture: Quasi experimental evidence from E. AfricaBashaasha, Bernard; Laker-Ojok, Rita; Norton, James B.; Owori, M.; Peck, D. (2013)Conservation Agriculture is a recent and evolving concept to land management that seeks to optimise crop yields and farm profits in a manner that balances economic and environmental benefits. The underlying principles include avoiding soil tillage, maintaining soil cover and retaining crop residues, practicing crop rotations and improved fallows, precision placement of appropriate fertilisers, pesticides and herbicides (targeting of inputs), reliance upon integrated pest management (IPM) principles and avoidance of soil compaction, among others.
- Assessing conservation agricultural production systems (CAPS) for small holder farmers in rain-fed farming system in sub-Saharan Africa (SSA)Nambozo, J.; Norton, Jay B.; Okeyo, M.; Odhiambo, Judith A.; Owori, M.; Oluko, P.; Ogonga, P. (2012)The challenge of sufficient food production by farmers in rainfed farming systems of sub-Saharan Africa is exacerbated by soil degradation and poor soil nutrient status. The objective of this study was to assess the effects of reduced and no tillage and velvet bean (Mucuna pruriens) cover crop on greenhouse gas (GHG) emissions and noxious weed population in alternative cropping practices to maize-bean production. Using a completely randomized block design, four replications of three tillage intensities and three cropping practices were established on two climatically different sites: Tranz-Nzoia in western Kenya, and Tororo in western Kenya and eastern Uganda, respectively. While CO2 emissions are comparable among sites and tillage treatments, N2O had significantly higher emissions in low elevation sites (where there are two growing seasons) and CH4 assimilation declined under reduced and no-tillage at high elevation sites. Reduced tilling also had a lower presence of narrow leaf species of weeds than deep tillage, but shallow hoeing had a lower weed density than no-till methods.
- Assessment of baseline socio-economic conditions of beneficiaries of SANREM/CAPs Project: Case study of smallholder farmers in eastern Uganda and western KenyaOwori, M. (Laramie, WY: University of Wyoming, 2013)The purpose of this study is to assess baseline socio-economic data collected from 790 households (HHs) in the SANREM/CRSP conservation agricultural production systems (CAPS) project areas of Trans-Nzoia and Bungoma districts in western Kenya, and Tororo and Kapchorwa districts in eastern Uganda. Surveys were administered before local farmers began working closely with researchers to co-design and test improved CAPS. The aim of my analysis is to identify socio-economic differences in the four districts surveyed, and factors that might hinder or foster adoption of improved CAPS by smallholder farmers in these districts.
