Aflasafe products tested in Ghana for aflatoxin control in maize and groundnut

With support from the Africa RISING project, a management strategy using biocontrol products containing native atoxigenic A. flavus fungi to reduce crop aflatoxin content has been developed for use in Ghana by IITA and partners. When products are applied at the right crop development stage, the atoxigenic fungi competitively displace aflatoxin-producers residing in treated fields and, in so doing, crop aflatoxin content is reduced.

Doubled-up legume technologies in conservation agriculture show potential for scale up in Zambia

The doubled-up legume system in conservation agriculture is premised on the belief that while farmers will be in a position to get the usual benefits of the doubled-up legumes (‘double’ the grain output per farm, hence more food and also ‘double’ soil fertility through the leafy biomass components of groundnuts and pigeonpea); they will also potentially benefit more from increased moisture retention towards the end of the season as well as reduced labor in land preparation, if the backbreaking conventional tillage practice of ridging can be avoided.

Pushing back against fertilizer use myth in northern Tanzania

In Babati District, northern Tanzania, a popular but misleading myth persists. That use of inorganic fertilizer ‘kills’ the soil. For several years, majority of farmers in the district have desisted from use of fertilizer to replenish depleted soil nutrients. Africa RISING researchers have for the past five years, invested significant resources and effort to dispel this myth. Continue reading

No one size fits all! Lessons from legume–cereal rotations in smallholder farms

Through its research-in-development work on legume–cereal rotations in Tanzania and Malawi, Africa RISING has established that these rotations work better for larger farms, while intercropping targeted at smaller farms ensures crop diversity, while giving an opportunity for legumes to be grown, thereby bringing associated nitrogen-fixation ecological benefits.

Gender implications of introducing forage chopper machines in northern Tanzania

In 2015, livestock scientists implementing Africa RISING research-in-development activities (R-in-D) introduced forage chopper machines in seven villages in Babati District, northern Tanzania. One year later (in 2016), social scientists evaluated the gender implications of the new processing practices among farmers’ groups. Continue reading

Shallow wells cushion smallholders in Mali and Ghana from the effects of climate variability

Africa RISING scientists from ICRISAT implemented a small scale pilot study in the semi-arid regions of southern Mali and northern Ghana to evaluate the impacts of climate variability at different scales (farm to watershed), using newly setup hydro-meteorological stations and hydrological modelling tools.

Economic evaluation of an improved grain storage technology in Tanzania

Insights from an economic evaluation of Africa RISING post-harvest technology (Purdue Improved Crop Storage bags) in Tanzania reveal how much farmers are benefitting by adopting the improved storage bags over the conventional storage options. Continue reading

Taking agricultural technologies to scale: The Africa RISING-NAFAKA partnership in Tanzania

In 2014, Africa RISING partnered with the USAID-funded NAFAKA project in Tanzania to scale-out best-bet technologies among smallholder farmers. Currently in its third year, the project, which also incorporates several community-based actors, has achieved great success. This poster provides an inside look at what it takes to make these kind of partnerships tick and the key lessons learnt from this nascent project. Continue reading

Insecticide spray regime effect on cowpea yield and financial returns in northern Ghana

While insecticide spraying offers the most effective management strategy for insect pests in farmers’ fields, most farmers in Ghana spray only once in most cases. The effect of a three spray regime was compared to conventional farmer practice (one spray) on yield and net financial returns of cowpea on-farm. Continue reading

Can maize farmers in northern Ghana increase economic benefits by applying more nitrogen?

A higher rate of nitrogen application provides higher economic benefit to farmers compared to the government recommended rate. There are visible differences between six maize varieties commonly grown in northern Ghana (used in this experiment) in terms of performance under higher fertilizer rate. Continue reading
