Most Ugandan maize growers give away a third of their margin in the same week, by selling the whole crop at the farm gate on the day it is shelled. Maize farming profit per acre in Uganda is a few hundred thousand shillings on an ordinary crop, and the largest single thing you control is not yield but when you sell. Maize is grown by more than half of Ugandan agricultural households in both seasons, which is exactly why the price falls when everybody harvests.
This page works the profit side. The item by item input stack is on the page covering what maize farming costs, and it appears here only as a total to subtract. What gets the attention instead is the yield gap, the harvest glut, and the arithmetic of holding grain rather than dumping it.
Maize Farming Profit Per Acre: the Numbers Are Smaller Than You Think
An acre of maize is a small business. On the national average yield at an ordinary farm gate price, gross revenue from one acre sits around 700,000 UGX, and the margin left after inputs is in the low hundreds of thousands. A well managed acre with improved seed and fertilizer can gross two or three times that. Neither figure is life changing on its own, and that is the first honest thing to say about maize.
What maize has instead is reliability. The price does not collapse five fold the way tomato does, the grain keeps if you dry and store it properly, and a failed crop loses you a modest amount rather than a catastrophic one. Maize is the low value, low volatility enterprise. Growers who want a bigger number per acre should be comparing it against horticulture and accepting the risk that comes with that, rather than expecting maize to behave like a cash crop.
Profit per acre in maize comes from three places, and they are worth ranking honestly. Yield is the biggest single driver and the hardest to move. Sale timing is second and by far the cheapest to change. Cost control is third and the one most farmers spend their attention on.
Maize Yield Per Acre in Uganda: the Gap Between Potential and Average
The gap here is the widest in Ugandan agriculture. The Uganda Bureau of Statistics Annual Agricultural Survey, run with the Ministry of Agriculture and FAO, put national maize productivity at 2.2 tonnes per hectare, which is about 890 kg per acre, roughly nine bags of 100 kg. An FAO assessment in the central cattle corridor found local varieties yielding 300 to 600 kg per acre with no fertilizer at all, which is three to six bags.
Against that, NARO lists Longe 10H at a yield potential of 8 to 10 tonnes per hectare, medium maturity inside 120 days, with tolerance to drought and to foliar disease. That is roughly 3,200 to 4,000 kg per acre, or 32 to 40 bags. So the research potential is four times the national average, and nothing about the seed is secret or expensive.
One detail from the same national survey is worth knowing, because it runs against the usual advice. Median seed rates actually applied by Ugandan farmers ran from 9.1 to 24.3 kg per acre by sub region, and in more than half of sub regions farmers were planting more seed than NARO recommends. Overseeding does not raise yield; it raises your seed bill and crowds the crop. The seed rate page has the recommended figures, and the variety comparison covers which improved types suit which altitude and season. For the agronomy of moving from nine bags to twenty, the yield page is the place to start.
What an Acre of Maize Costs to Grow
Cost belongs on its own page and this one only needs a total. The band is wide because maize is grown at very different intensities in Uganda. Named growers reporting a recent season spent roughly 250,000 to 1,000,000 UGX per acre in total on low to moderate input rainfed crops, covering land rental, pesticides and labour between them. That is a whole acre figure, not a single line: individual items such as top dressing fertilizer sit well inside it. Add certified hybrid seed at the recommended rate, basal and top dressing fertilizer, tractor ploughing and hired labour throughout, and a managed acre runs to 1,200,000 to 1,800,000 UGX.
An FAO assessment costed the labour side in days rather than shillings, which is the more useful way to think about it on a family farm: slashing takes four mornings for two workers, manual ploughing about six days, planting four days, two weedings twelve days between them, and harvesting eight days. Those days are free if you have them and a cash cost if you do not, which is the real reason two farms on the same soil report totals that differ by a factor of four.
The same assessment found something worth carrying into your own budget. Improved varieties returned a benefit cost ratio of 2.9 against 1.75 for the local variety, because the higher seed and fertilizer spend was more than covered by the extra yield, and because improved varieties needed less weeding labour. Spending more on seed lowered the cost per bag. Work the full stack on the maize cost page before you use the totals above.
Maize Farm Gate Prices and the Harvest Glut
Farm gate maize in Uganda plausibly ranges from about 500 to 1,200 UGX per kilogram, and where you land in that band has more to do with the week than with your grain.
The pattern repeats every season. Fresh grain arrives from the major producing areas at first season harvest, supply surges, and farm gate prices drop. Ugandan market monitoring recorded farm gate maize falling sharply to about 900 UGX per kilogram in Hoima, Kiboga and Kyankwanzi as volumes came in. In the greater Kibaale area a season that had paid 900 to 1,000 UGX was followed by one paying 500 to 700 UGX after many more farmers planted on the strength of the earlier price. Named growers there reported selling at 750 rather than the 1,000 they had budgeted, one at 500, and one at 250 UGX per kilogram.
The reason those farmers accepted those prices is the part that matters. They said, plainly, that they had nowhere to store the maize and it would have spoiled. That is not a price problem. It is a storage problem showing up as a price problem, and it is the single most expensive thing in Ugandan maize farming.
Against the harvest low sits a seasonal recovery, and it is worth being precise about the evidence for it. Ugandan seasonal market outlook reporting recorded staple prices falling to between 13 and 41 percent below the five year average once the main harvest was in, then rising by 6 to 36 percent across monitored markets as cereal stocks depleted. That rise was reported for beans, maize and sorghum together rather than for maize alone, and the sharpest pressure was in unimodal areas. So treat 6 to 36 percent as an illustrative premium band for the arithmetic below, not as a measured maize national figure. For where the market actually sits, use the living maize price page.
Profit Per Acre at Four Yield and Price Combinations
Here is the revenue side. Yields at the bottom are the verified national average and the verified local variety range; the 2,000 kg managed figure is a planning assumption sitting between the national average and the research potential, and it is labelled as such. Prices are farm gate, inside the band above.
| Scenario | Yield kg | Farm gate UGX | Gross UGX |
|---|---|---|---|
| Local seed, no inputs | 500 | 700 | 350,000 |
| National average | 890 | 800 | 712,000 |
| Managed, sold at harvest | 2,000 | 800 | 1,600,000 |
| Managed, glut price | 2,000 | 500 | 1,000,000 |
| Managed, stored and held | 1,900 | 1,000 | 1,900,000 |
Now subtract the cost that goes with each level, because a farmer harvesting twenty bags did not spend a local seed budget to get there.
| Scenario | Gross UGX | Cost UGX | Result UGX |
|---|---|---|---|
| Local seed, no inputs | 350,000 | 300,000 | plus 50,000 |
| National average | 712,000 | 500,000 | plus 212,000 |
| Managed, sold at harvest | 1,600,000 | 1,200,000 | plus 400,000 |
| Managed, glut price | 1,000,000 | 1,200,000 | loss 200,000 |
| Managed, stored and held | 1,900,000 | 1,300,000 | plus 600,000 |
Three readings come out of that table. A subsistence acre with no bought inputs roughly pays for itself and no more. A managed acre sold into a glut loses money, which is exactly what happened to growers in Kibaale. And the same managed acre, held for a few months and sold into the seasonal rise, makes about half again as much as the one sold at harvest. Nothing changed agronomically between those last two rows. Work your own figures through the farm profit calculator.
Storage and Sale Timing: the Real Profit Lever in Maize Farming
Take 2,000 kg, twenty bags, and a harvest price of 800 UGX. Sell it all on shelling day and you have 1,600,000 UGX. Hold it into the period when stocks deplete, and on the illustrative 6 to 36 percent premium band the same grain is worth between 848 and 1,088 UGX a kilogramme. At the top of that range, holding twenty bags with no loss is worth 2,176,000 UGX, a gain of 576,000 on an acre where you did no extra work.
Then take the loss off. Published research puts dry weight losses in stored grain at up to 30 percent, and more than 73 percent of Ugandan farming households store grain in woven polypropylene bags, which do not protect it. Store the same twenty bags badly for four months, lose thirty percent, and you have 1,400 kg. Even at the top price of 1,088 UGX that is 1,523,200 UGX, which is less than you would have got by selling at harvest. At the bottom of the seasonal rise it is far worse.
The evidence that this works at scale is Ugandan. A World Food Programme supported intervention across 28 districts of northern and eastern Uganda distributed hermetic bags and silos to 16,600 households, and in participating households storage losses fell by at least 98 percent and household incomes doubled. The same research found awareness of hermetic storage at only 53.3 percent and actual use at 17.6 percent, with local availability and cost the main constraints. This is a known answer that most farmers have not got to yet.
There is a trap on the other side of the ledger. Peer reviewed Ugandan work describes farmers selling shortly after harvest because they do not trust their storage, then buying grain back from traders during the lean season at higher prices than they sold it for. A household that sells twenty bags at 800 and buys five back at 1,100 has paid the middleman twice.
Drying Maize to Standard Before You Store It
Storage starts with drying, and drying has a number attached to it. The East African Community maize grain standard sets a single maximum moisture content that applies across grades one, two and three, and published editions of that standard put it at 13.0 or 13.5 percent by mass. The figure that decides which you meet is the edition your buyer is working to: the draft fifth edition of the maize grain specification gives 13.5, while the edition reproduced in a joint FAO, WFP and IFAD study of Ugandan food loss gives 13.0. Both describe the same table, with broken kernel limits of 2.0, 4.0 and 6.0 percent by grade. Dry to 13.0 percent or below and you satisfy every version of it. That is not an exporter's guideline. It is the line between grain that keeps and grain that moulds in the bag.
Above it, two things happen. Moulds grow, and some of them produce aflatoxin, which is why UNBS monitors maize grain and flour quality and why serious buyers reject wet grain outright. Weevils also do far more damage in grain that is not properly dry. So drying does more than protect a store; it gives you access to the buyers who pay more than the farm gate.
Judging moisture by biting a grain does not get you to 13 percent reliably. A moisture meter does, and it is the cheapest piece of equipment that changes what your maize is worth. Drying on bare ground picks up soil, stones and contamination that downgrade the sample. The drying guide and moisture management page cover the practice, and the storage guide covers what happens after.
What Storage Costs and What It Can Lose You
Bag prices, shelling charges and drying services all move by region and season in Uganda, so this page does not put figures on them. Get current quotes locally. What it can give you is the decision rule, which does not depend on the prices.
Run this comparison before harvest. Work out your expected tonnage. Apply the low end of the premium band, six percent, to your expected harvest price, and see what the premium is worth on that tonnage. Then get a quote for enough hermetic bags to hold it. If the premium at the low end of the range comfortably exceeds the bag cost, storage pays and the bags are reusable across seasons, which makes the second year cheaper. If it does not, you are too small to store this season and should sell.
Two costs people forget. One is the cash you are not holding while the grain sits, which matters if you are paying interest on a loan. Arrange the repayment date well after your intended selling date, not after harvest, or the loan will force you into the glut regardless of your plan. The other is the attention storage needs: grain has to be checked, and a store has to keep out rodents and rain. The hermetic bag page and weevil prevention page cover the practical side. Where a storage insecticide is used at all, the rate and the withdrawal period are on the product label and the label is what you follow, because this grain is going to be eaten.
What Wipes Out Maize Profit Per Acre
The glut you planted into. A good price one season pulls extra planting the next, supply surges and the price falls. The farmers who lost money in Kibaale had responded rationally to the previous season's price. This is the most common way a technically sound maize acre loses money.
No storage, so no choice. A farmer who must sell in harvest week is a price taker at the worst moment of the year. Everything in the storage sections above is about converting that into a choice.
Fall armyworm caught late. It moves fast and it eats the growing point. Scouting weekly through the vegetative stage is what keeps it from taking a large share of your yield. Rates and intervals for any product are on the label, and an extension officer can confirm what is registered for maize in Uganda. The fall armyworm page covers scouting and management.
A dry spell at flowering. Maize is least forgiving of water stress around tasselling and grain filling. One named grower in the Kibaale reporting had budgeted 90 sacks and harvested 52 after a prolonged dry spell, then had to sell below his target price as well. Two things went wrong and they compounded.
Post harvest loss. The East African Grain Council puts Uganda's annual post harvest maize loss at roughly 20 percent of the crop, and estimates that wider uptake of hermetic storage would save about 64,950 tonnes a year worth about 49.1 billion UGX. A fifth of the national crop is lost after it has already been paid for in seed, fertilizer and labour.
Selling at the Farm Gate, Bulking, or Holding Stored Grain
Three routes, three different prices, three different amounts of work.
Farm gate to a trader. Immediate cash, no drying standard to meet, lowest price. Growers in the reporting cited above also complained about middlemen manipulating measurements, which is a separate leak from the price itself: weigh your own bags before anyone else does.
Bulking with other farmers. A group offering twenty tonnes negotiates differently from an individual offering twenty bags, and buyers who pay more for graded, properly dried grain will deal with a group and not with a single smallholder. It takes organisation and a shared standard on moisture. How aggregation works sets out the mechanics.
Holding stored grain. Highest price, requires drying to standard, storage that works and cash to wait. This is where the seasonal recovery in price is collected, and it is the only one of the three routes that raises your price without raising your yield. Where maize is bought lists the channels each route leads to.
Is an Acre of Maize Worth Planting
On its own, as a cash enterprise, one acre of maize is thin. A few hundred thousand shillings of margin on an ordinary crop does not justify borrowing, and at the national average yield with hired land and labour it does not reliably justify anything.
Maize earns its place for other reasons. It feeds the household, so part of the return is food you did not buy. It stores, unlike every vegetable, which makes it the crop you can hold while waiting for a price. It is the most traded staple in the country, so there is always a buyer somewhere. And it scales without much more skill: the same practice that gives twenty bags on one acre gives two hundred on ten.
The version of maize that pays is the managed one: improved seed at the correct rate, fertilizer, timely weeding, armyworm caught early, dried to standard, stored properly and sold when stocks are short. The version that does not pay is local seed, no fertilizer, sold at the farm gate in harvest week. Both are maize farming and they are different businesses. The business ideas hub puts maize next to the enterprises competing for the same land and money.
Maize Profit Questions Ugandan Farmers Ask
How many bags should I expect from an acre? Nine bags is the national average. Three to six is what local seed without fertilizer gives. Eighteen to twenty five is what a properly managed acre with improved seed and fertilizer gives. Claims of forty bags describe a released hybrid's research potential rather than an ordinary rainfed season.
Is hybrid seed worth using instead of saved local seed? On the evidence, yes, and the yield gain is only part of it. An FAO assessment in Uganda found improved varieties returned a benefit cost ratio of 2.9 against 1.75 for the local variety, partly because they needed less weeding labour. Buying good seed and then skipping fertilizer wastes most of that advantage.
How long should I store maize before selling? Long enough for stocks to deplete, which in practice means months rather than weeks, since the seasonal rise builds gradually. The harvest to harvest gap in Uganda can exceed six to nine months, so there is room. What decides it is whether your grain is dry enough and your household can wait.
Can I store maize in ordinary woven bags? You can store it; you will lose a large share of it. Woven polypropylene bags are what more than 73 percent of Ugandan farming households use and they do not protect grain, with published losses running up to thirty percent. That loss can exceed the entire price gain you were storing for.
What do serious buyers require? Grain at or below 13 percent moisture, clean, free of foreign matter and without visible mould. Published editions of the East African Community maize grain standard set the ceiling at 13.0 or 13.5 percent, so 13 percent clears all of them, and UNBS enforces the standard on traded maize. Meeting it is what moves you out of the farm gate price and into the graded one.
Should I switch from maize to beans? Farmers in the reporting cited on this page were switching to beans after a price collapse. Beans carry their own disease and price problems, and the national bean yield is lower again. Rotating between them is usually the better answer than abandoning one, because maize after beans benefits from the nitrogen and the pest break.
Does drying and storing really change the price that much? On an illustrative premium band of 6 to 36 percent, twenty bags are worth somewhere between roughly one hundred thousand and six hundred thousand shillings more than they were at harvest. Whether you keep that depends entirely on losing almost none of the grain while you wait.
Maize prices in Uganda move with the season and the district, so treat the figures here as a method and not a forecast. Before harvest, check the living maize price page on this site, get a current quote on storage bags and shelling from dealers near you, weigh your own bags, and work out the price at which holding beats selling on your own tonnage. Then decide whether you are selling in harvest week or storing, before the traders arrive rather than while they are standing in your compound.
