Smart Irrigation Design Proves Pivotal in Namibia’s First Successful Blueberry Harvest
by Brandon Moss
July 2020 saw the commencement of Namibia’s first-ever commercial harvest of blueberries by local company Mashare Berries Farming (Pty) Ltd. The historic harvest is currently underway on a 20 ha development located close to the Okavango River between Mashare and Mupapama villages in Kavango East, northern Namibia. The fruit is being sold and marketed under the trading name Namib Blue, and is earmarked for Namibian as well as international consumption. Exports are set to commence in August to markets across Europe and Asia and Indian Ocean islands, including Mauritius, the Maldives and Seychelles.
According to Willem Mostert, Namibian manager of Cherry Irrigation, whose team designed and implemented the fully automated drip irrigation (and fertigation management) system for the landmark project, the quality of the fruit harvested has so far been exceptional.
“A few years ago, no one would have dreamed that you could grow high-quality blueberries in a country as dry as this,” says the Namibian-born Mostert. “We’re proving what’s possible with the right planning, infrastructure and management in place.”
Mashare project director Albert Basson says the 2020 harvest is set to continue into late October. “We’re projecting a yield of up to 150 tonnes, as different varietals reach maturity. Currently, three varietals imported from the US-based grower Fall Creek have been planted on the property: AtlasBlue®, JupiterBlue® and BiancaBlue®. The plantings were established in November 2019, with 16 ha under net, 2 ha in tunnels and 2 ha of an open field.”
Mashare Berries plans to double its production area by the end of 2021,with Cherry Irrigation on board for the expansion. “Ultimately, within the next five years we would like to expand blueberry cultivation across 200 ha to 300 ha of land in the region,” Basson adds.
Cherry Irrigation’s executive director, Charles Cherry, believes the success of the pilot project attests to the enormous untapped potential of arid or semi-arid regions. “These area can effectively produce a range of crop types through careful water and resource management.
“We’re seeing first-hand from this development and others we’re involved with across Namibia that customised irrigation design is the way forward. Simply put, it ensures environmental sustainability and commercial profitability over the long term,” he adds.
“The outlay of quality equipment, custom designs, smart technology, and AI (artificial intelligence) monitoring solutions may cost more initially. But for crops like blueberries that are (highly) sensitive to climatic conditions and soil and water quality, we believe this approach is crucial to success,” Cherry explains. “If you do it right, look at what you can achieve.”
Basson agrees. “We partnered with Cherry Irrigation after seeing their success with custom system designs for blueberry plantations in South Africa. Like us, they recognise the enormous agri-potential of Namibia that we are working to unlock.”
Mashare Berries is a subsidiary of Mashare Irrigation, which produces a variety of grains and vegetables, including wheat, maize, sorghum potatoes, onions and cauliflowers in Kavango East, for the local Namibian market.
“With the right teams, investors and companies in board, Namibia has the potential to be a world-class production hub for fresh goods,” says Cherry. “There is a big national drive to develop local resources properly and to produce more locally (fruit, vegetables, livestock fodder and other horticultural products), thereby reducing the need to import.
Shade nets protect Mashare’s blueberry bushes from the harsh sun in Kavango East, North Namibia. These images were taken in January 2020, two months after they were planted. Harvesting of the JupiterBlue® blueberries began in early July and is set to continue into October as different varieties ripen
Blueberries reach maturity and ripen at different stages on one bush, as can be seen on the picture. This allows for a longer harvesting season usually lasting 3 to 4 months
Because Blueberries must be hand-harvested to ensure that fruit is not damaged or bruised, the industry offers excellent employment opportunities for seasonal workers. During peak harvest times, a larger staff contingent is required for this highly labour intensive work. Pictured here are Mitrud Shirongo (left) and Ester Marungu (right) from Mashare village
The Netafim NetaJet™ is a modular CE-compliant automated dosing system installed by Cherry Irrigation at Mashare. The device, which is installed in the pumphouse, is responsible for measuring Ph levels and EC levels of plants, backflushing the filter and mixing fertiliser with water (dosing) for fertigation of blueberry bushes
