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.
This evidence brief explains how Africa RISING is using an intercropping system known as ‘doubled-up’ legume technology using two complimentary grain legumes. Groundnut–pigeon pea intercropping is the most successful doubled-up system thanks to the two crops’ contrasting structures and maturity dates.
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.
Good agriculture practices (GAPs) are the low-hanging fruits for extension of new technologies. They are easily adoptable, give farmers an immediate benefit, and help in the gradual shift from traditional plough or hoe-based systems with maize monocropping to more sustainable and adapted ways of agriculture.It is against this background that the Africa RISING project theme on Sustainable Intensification of low input farming Systems has intensified the out scaling of simple component technologies in a mother-and-baby trial approach in three districts of Eastern Province, namely Sinda, Chipata, and Lundazi.
Findings from three districts in Zambia revealed that smallholder farmers use agricultural technology innovations and diversification strategies to manage droughts and enhance their resilience to climate shocks.
Farmers in southern Africa plant maize extensively on large areas, harvest less than 2 t/ha on average, extracting already depleted nutrients from the soil while trying to become food secure and escape from poverty―an impossible task! In Eastern Province of Zambia, farmers are being offered a range of solutions by Africa RISING that provide a way out of this poverty trap. These technologies, options, and approaches include drought- and stress-tolerant maize germplasm, conservation agriculture (CA), improved rotation and intercropping with grain legumes, agroforestry, and green manure cover crops.
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.
How switching to improved agricultural technologies like hybrid maize varieties and application of bladed fertilizers catalyzed a young female farmer’s dramatic rise from an off-season casual laborer to a champion farmer in rural Tanzania.
On 5th and 6th May 2016, the project’s researchers, fields agents and farmers organized and held had a Farmers’ Field Day event. This gave an opportunity for farmers who are not taking part in the project to learn and share experience with their colleagues who are beneficiaries about Good Agronomic Practices. The farmers also got the chance to visit demo plots for self-observations.
A multi-locational study in Zimbabwe aimed to determine the effect of four tillage systems on maize, cowpea and soybean yields, and evaluate the economic performance of the conservation agriculture (CA) systems relative to conventional plowing.
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.
Since September 2013, the SIMLEZA-Africa RISING project tested a range of improved agricultural technologies in Chipata and Katete districts of Zambia with the aim of sustainably intensifying the productivity of small holder farmers in those parts of the country. How did the project scale-out those technologies to the farmers? What worked and what didn’t?
New postharvest technologies put a smile on the faces of Tanzania’s smallholder farmers
In the second year of practicing conservation agriculture (CA) introduced to him through the SIMLEZA-Africa RISING project; Stephen Nyirenda, a 38 year old farmer from Lundazi District in Zambia has been able to increase the productivity of his farm in ways he never thought possible. In just two seasons he’s been able to buy two cows from the extra proceeds he’s been getting from his farm. Not a mean feat, but which he attributes squarely to this new found way of sustainable land management
Thanks to an emerging breed of bold farmers who have taken to producing legume seeds for cultivation by their colleagues, the challenge of legume seed availability is being met in Eastern Zambia. For the past two years, Tichoke Phiri, a woman farmer from Kawalala camp in Katete district has been growing improved cowpea varieties through the Africa RISING project and selling it at a minimal cost to her fellow farmers in Kawala camp. The returns from her work have been very rewarding
Against the odds stacked against them due to climate change; farmers in Chipata and Katete districts in Zambia where the SIMLEZA-Africa RISING project was being implemented are ramping up their farm productivity using conservation agriculture techniques. Richard Soko, a farmer from Chipata District is one such farmer
MacDonald Bright Jumbo, Maize Molecular Breeder at International Maize and Wheat Improvement Centre (CIMMYT) in Nairobi , introduces himself and his work in the Africa RISING program. It is one of a series of portraits of key people in Africa RISING.
The Africa RISING-NAFAKA-TUBORESHE CHAKULA scaling project is working to introduce farmers in Kongwa and Kiteto districts in Tanzania to simple seasonal in-situ water-harvesting innovations
The SIMLEZA – Africa RISING project in Zambia provides support to seed companies in seed business development, including building capacity for training and technical assistance, entrepreneurial skills, varietal release and registration, seed multiplication and commercialization to enhance their ability to produce and market improved seed.
An Africa RISING research brief explains the effect of sheep and goat stocking density (SSD) on grain yield and soil properties in small-scale mixed farming systems.
Researchers say they are close to a breakthrough in developing maize lethal necrosis (MLN) tolerant maize varieties, that will help farmers in East Africa successfully fight the disease.
Productivity of hybrid and open-pollinated maize grown in association with erect and spreading cowpea types was evaluated on-farm in Africa RISING intervention communities in northern Ghana.
Frédéric Baudron, senior tropical agronomist at the International Maize and Wheat Improvement Center (CIMMYT) in Ethiopia, introduces himself and his work with the program.
Maize is an important cereal crop in Ghana, especially in the northern part where it is replacing sorghum and millet. High yielding, drought and Striga tolerant varieties have recently been released.
In this five-minute video, Bright Jumbo, the Africa RISING research lead on the management of maize lethal necrosis disease, explains the progress made by the team as at March 2015.
Souleman Ballo and his fellow farmers in the seed cooperative know only too well how important good seeds are for a farmer’s wealth. To address the challenge of accessing quality seed, their cooperative has been working with researchers at the International Crops Research Institute for the Semi-Arid-Tropics (ICRISAT) and the Institut d’Economie Rurale (IER) to develop improved varieties of sorghum and millet leading to remarkable yield gains.
