Early Rains Threaten Zimbabwe Wheat As Harvest Reaches 30%
Birds rose in a cloud above the wheat plots at the Department of Research and Specialist Services in Harare as the first drops began to fall. Beneath the darkening sky, Professor Obert Jiri did not bother to hide his concern.
The Permanent Secretary in the Ministry of Agriculture, Mechanisation and Water Resources Development warned that the early rains hitting parts of the country this week could damage Zimbabwe’s winter wheat crop if wet, cloudy conditions persist. Around 30% of the national crop is already ready for harvest.
“The rains are worrying. Particularly if they have 20 ml in 24 hours and if they also continue over 3 days without sun breaks. So, that would be worrying,” Professor Jiri told farmers and seed companies gathered for a National TAAT Wheat Field Day in Harare.
Zimbabwe planted 130,000 hectares of wheat this winter. Harvesting has started and is expected to run through to October, making the next few weeks highly sensitive for growers racing against the weather.
How Much Rain Is Too Much For Wheat?
Wheat close to maturity is highly vulnerable to prolonged rain. Heavy showers can stain the grain, encourage sprouting on the head, and trigger disease, all of which erode quality and price. For a country pushing for wheat self-sufficiency under National Development Strategy 1 (NDS1), those losses cut far deeper than one season’s income.
Professor Jiri said the biggest risk lies in areas that receive sustained downpours without sunshine to dry the crop.
“So, areas that receive these rains and they have sun breaks, that would not be of concern. But we are saying that farmers that have wheat that is ready for harvesting, they should expedite the harvesting process and also use dryers,” he said.
Regions receiving more than 20 millimetres of rain in 24 hours, repeated over three straight days without sun, are especially at risk, he explained.
FFA Explainer:
When wheat nears harvest, its grains have low moisture. Prolonged rain raises this moisture level and can cause kernels to sprout while still on the head (pre-harvest sprouting), promote fungal infections, and stain grain. This reduces baking quality, lowers grades, and can force farmers to sell at discounts.
Farmers Urged To Harvest Fast And Use Dryers
With roughly a third of the national crop already at harvest stage, the message from government is blunt: do not wait for perfect weather. Move now.
“So, more than 30% of our wheat is now ready for harvesting and farmers have already started harvesting,” Professor Jiri said, urging those still hesitating to act quickly.
He called on farmers to use commercial drying equipment wherever possible to prevent grain damage.
“Remember, we have smart silos with robust drying capabilities. We encourage farmers to take advantage of these drying facilities and ensure that they harvest and dry as quickly as possible,” he said.
For many large and medium-scale farmers across Mashonaland and the Lowveld, access to such smart silos – often fitted with controlled drying systems – can make the difference between selling top-grade wheat and offloading downgraded grain at a loss.
Smallholders around districts such as Nyabira, Bindura, and Marondera who entered wheat under irrigation schemes face a sharper dilemma: they often lack on-farm drying facilities and must decide quickly whether to harvest slightly early and negotiate access to commercial dryers, or risk weather damage while waiting for the crop to fully mature.
What Can Smallholders Do Right Now?
For farmers in contract schemes or irrigation projects, especially youth and women who entered wheat production through government and private programmes, several practical steps stand out:
- Walk the fields daily and prioritise the driest, most mature sections for immediate harvest.
- Coordinate with neighbours or local millers to arrange shared transport and drying space in smart silos.
- Clear storage areas in advance so grain can move quickly from field to dryer to safe storage.
- Keep in constant touch with agronomists and scheme managers for updated weather and harvest advice.
These decisions echo the broader goals of NDS1 and the AU Agenda 2063, which both place food security and climate-resilient production at the centre of national development and regional integration.
TAAT Pushes Climate-Smart Wheat Varieties
The National Wheat Field Day in Harare was organised under the Technologies for African Agricultural Transformation (TAAT) initiative. While the rains stole some of the attention, the main agenda was clear: showcase climate-smart wheat varieties that can hold their own under heat and disease pressure.
FFA Explainer:
TAAT is a continent-wide programme supported by partners to speed up the spread of proven agricultural technologies. For wheat, this means varieties that yield well, resist common diseases, and cope better with higher temperatures linked to climate change.
Through TAAT, the Ministry of Agriculture is supporting researchers to breed and promote wheat varieties that can withstand warmer conditions and disease pressure – critical traits as weather patterns shift under climate change.
During the field day, seed companies lined the research station plots with colourful banners and variety labels. Twenty-three different wheat varieties were on display, each promising a slightly different mix of maturity period, water need, and disease performance.
For farmers from different agro-ecological zones – from the cool Highveld to hotter low-lying areas – that diversity of choice is no longer a luxury. It is now a survival strategy.
Seed Companies Offer Faster, Thirst-Saving Varieties
Among the exhibitors was Valley Seeds, positioning itself as a partner in the country’s bid to maintain wheat self-sufficiency.
Agronomist Sandra Bhaiwa said the company is working with government to keep the country adequately supplied with locally grown wheat, not just through volumes, but through varieties that make better use of scarce water.
She highlighted a quick-maturing variety that requires less water, including types such as Limpopo and Zambezi.
“Zambezi wheat variety is a medium seed that takes a bit longer than Limpopo to mature,” Sandra explained, sketching out options for different regions. Faster, lower-water varieties give farmers in drier or hotter zones a chance to harvest before heat and disease do their worst.
For irrigated schemes along the Lowveld or in drier pockets of Mashonaland West, such shorter-season varieties can shave crucial days off the growing cycle, freeing up irrigation water and reducing exposure to late-season weather shocks like the early rains now causing jitters.
Farmers across the region have increasingly turned to climate-smart crop choices as erratic rainfall patterns undermine traditional planting calendars.
Connecting Farmers And Breeders
Behind each variety in the field lies years of breeding work. Yet those efforts only pay off if farmers know what is available and why it might suit their soils, climate, and market.
That is where TAAT’s wheat platform comes in, said Jairos Masawi, a wheat breeder and the TAAT focal person.
“So this is the basic idea, to say we are setting the stage where we showcase all the varieties that are available. Then from there, farmers will have a wide choice, by choosing varieties that are suitable for their respective agro-ecological agenda,” Masawi explained.
By walking through plots of side-by-side varieties, farmers can see how each one stands, how it fills grain, how it handles disease, and how long it takes to mature. For a young farmer from Mvurwi or a woman irrigator from Chinyika Irrigation Scheme, that visual comparison often teaches more than brochures ever could.
The approach matches the spirit of farmer field schools and participatory trials that have spread across Zimbabwe in crops such as maize and sugar beans, giving communities a stronger voice in varietal choices.
Even Tough Varieties Need Protection
One message at the field day cut across all stands: climate-smart and disease-tolerant does not mean “spray-free”. Warmer temperatures are changing the behaviour of pests and pathogens.
Martin Chamunorwa from CP Chemicals said even wheat varieties bred with disease resistance or tolerance must still be protected, especially in a warming climate.
“These varieties come in with embedded traits of either resistance or tolerance. Our temperatures are now warmer and cycles for diseases are becoming shorter, and frequent but since our variety has some element of tolerance, we will then use minimal herbicides just to assist fight the diseases,” Chamunorwa explained.
Shorter, more frequent disease cycles translate into more infection pressure over a season. That means farmers cannot rely only on genetics; they must combine good varieties with timely, well-targeted sprays, correct fertiliser management, and disciplined crop rotation.
FFA Explainer:
“Disease-resistant” varieties carry genes that slow or block infection. “Tolerant” varieties may still get infected, but suffer less damage and yield loss. Neither type is invincible. Without basic crop management – from weed control to timely spraying – even tough varieties can succumb under severe pressure.
For farmers eyeing higher yields, the message is clear: treat the variety as a strong foundation, not a magic shield. Agronomists across Zimbabwe have shared similar lessons in crops like maize under fall armyworm pressure.
Wheat, Weather, And The Bigger Picture
The early rains have arrived as Zimbabwe pushes to secure its own bread basket. Wheat self-sufficiency aligns with UN Sustainable Development Goal 2 on zero hunger, but also with the economic stability targets in NDS1.
When the weather misbehaves at harvest, it exposes every weak link – from delayed harvesting and limited drying capacity to gaps in communication between extension officers and farmers.
Yet the scene at the Harare research station offers a different image too: breeders and agronomists standing shoulder to shoulder with farmers, seed companies lining plots with 23 varieties, and a government official bluntly warning of risk while pointing to practical tools like smart silos and dryers.
For the wheat farmer in Banket or Insiza watching the clouds, the next few days will be tense. But they are not without options. Harvest faster. Dry smarter. Choose varieties better suited to the heat and disease of a changing climate.
If those actions take root, the showers that raised alarm this week might also mark a turning point: where Zimbabwe’s wheat story shifts from chasing the weather to staying a step ahead of it.
