Is production intensification likely to make farm households food-adequate? A simple food availability analysis across smallholder farming systems from East and West Africa by Ritzema, Randall S., Frelat, Romain, Douxchamps, Sabine, Silvestri, Silvia, Rufino, Mariana C., Herrero, Mario, Giller, Kenneth E., López Ridaura, Santiago, Teufel, Nils, Paul, Birthe K., Wijk, Mark T. van

“…However, inadequate attention has been given to assessing whether benefits from intensification would be realized by farm households considering highly diverse resource endowments, household and farm characteristics, and agroecological contexts. In this study, we apply a simple energy-based index of food availability to 1800 households from research sites in 7 countries in East and West Africa to assess the food availability status of each of these households and to quantify the contribution of different on- and off-farm activities to food availability. …”

Inoculation and phosphorus fertilizer improve food-feed traits of grain legumes in mixed crop-livestock systems of Ethiopia by Belete, Sisay, Bezabih, Melkamu, Abdulkadir, Birhan, Tolera, Adugna, Mekonnen, Kindu, Woldemeskel, Endalkachew

“…This study was conducted to evaluate the effects of rhizobium inoculation (I) and phosphorus fertilizer (P) on yield and nutritional quality of grains and haulms of grain legumes (faba bean, chickpea, common bean and soybean) on farm across diverse agroecological locations in the Ethiopian highlands. The crops were subjected to four treatments [+I, +P, −I + P and a negative control (-P-I)] at multiple locations on farm during the main cropping season in 2016. …”

Grain legumes increase yield stability in maize based cropping systems by Chimonyo, Vimbayi Grace Petrova, Snapp, Sieglinde S., Chikowo, Regis

“…Six field trials were conducted across three agroecological zones over five cropping seasons. We used additive main effect and multiplicative interaction to assess grain yield stability of maize in unfertilized maize, maize fertilized with 69 kg N ha−1 (Mz69), maize–pigeonpea [Cajanus cajan (L.) …”

Environmental stability of iron and zinc concentrations in grain of elite earlymaturing tropical maize genotypes grown under field conditions by Oikeh, S.O., Menkir, A., Maziya-Dixon, B.B., Welch, R.M., Glahn, Raymond P., Gauch, G.

“…Twenty early-maturing elite tropical maize (Zea mays L.) genotypes were evaluated over 2 years at three locations representing three distinct agroecologies in West and Central Africa (WCA). The objectives were to analyse the pattern of genotype×environment interactions (GEI) and environmental stability of iron and zinc concentrations in grain using the Additive Main Effects and Multiplicative Interaction (AMMI) statistical model. …”

Exploring socio-ecological niches for forages in climate-smart dairy systems in Rwanda by Qingye, Huang

“…In this study, we used farming systems characterization and the agro-ecological and socio-economic characteristics of the forage technologies to quantitatively evaluate their suitability in socio-ecological niches in three agroecological zones in Rwanda. Impacts on milk yield and enteric methane emission for scenarios of grass and legume integration in banana fields were simulated through the Ruminant model. …”
