Ghana farmers’ group raises groundnut yield five-fold with improved varieties, breaks three-decade productivity barrier

Tridge summary

In Ghana, two new groundnut varieties, SARINUT 1 and SARINUT 2, have significantly boosted crop yields for local farmers, increasing production five-fold and combating leaf spot disease. This marks a major breakthrough in groundnut productivity, which had been stagnant for three decades due to the widespread use of an outdated variety. This improvement was possible thanks to a collaboration between CSIR-SARI and AGRITREE Sustainable Centre, supported by various projects, and was adopted by the Soglokonbo Groundnut Farmers Association for its high yield, disease resistance, and other beneficial characteristics. The adoption of these new varieties has not only increased yields and improved livelihoods of the farmers but also revitalized the groundnut farming sector in Ghana, with plans to introduce more improved varieties still in progress.

Two improved groundnut varieties have helped a group of farmers in Ghana increase their yields five-fold, breaking a three-decade stranglehold on the crop’s productivity. The improved varieties, SARINUT 1 and SARINUT 2, are also combating devastating afflictions of groundnut production like leaf spot disease in the country’s Savanna Region. The farmers’ group, Soglokonbo Groundnut Farmers Association in the region’s East Gonja district, has been using the improved varieties and good agricultural practises to produce around 1,200 kg per hectare in stark contrast to the 225 kg per hectare they were harvesting earlier. Reason for the historically low yields: prominence of a dated variety that was introduced in the region 30 years ago and was handed down or exchanged between farmers. Not only was the dated variety low-yielding, it was also highly susceptible to early and late leaf spot diseases that can wipe out as much as 80% of a field. With such prospects, several farmers in the ...
