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.
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.
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.
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.
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.
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.
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.
This poster provides a self-reflective look at the key lessons and what it takes to operationalize a robust M&E framework for a complex systems research program like Africa RISING.
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.
Insights from the results of an evaluation of different Africa RISING technology packages per farm type and per region in Northern Ghana.
A geospatial framework for delineating recommendation domains for crop varieties which are part of the Africa RISING technology packages.
Two posters on scaling techniques applied by the Africa RISING project in Tanzania were recently ranked 2nd and 3rd at a poster competition featuring over 50 entries in Ibadan, Nigeria.
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.
This poster, produced for the Tropentag 2016 conference, highlights a study that generated fundamental information for improved nutritional management in rural chicken production in Tanzania.
This poster, produced for the Tropentag 2016 conference, explains findings from studies which characterized the use of crop residues for livestock feed as an option for enhancing intensification in smallholder farms in Bahati District in Tanzania.
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.
