Short answer: Rice in Ghana grows in two very different systems. Lowland rice sits in inland valleys and irrigation schemes where you can hold and drain water, and upland rice grows rain-fed on slopes and forest-edge soils. Match the system to the land you have, plant certified seed of a variety recommended for your zone, and time sowing to the first reliable rains.
Key takeaways
- Choose lowland or upland by water, not habit. Lowland needs a field you can flood and drain; upland needs dependable rain at sowing and through flowering.
- Buy certified seed of a variety your district agric officer or CSIR-SARI has recommended for your zone, and keep the bag tag as a record.
- Transplant 21 to 25 day old seedlings at a spacing you can weed, usually around 20 by 20 centimetres in a lowland field.
- Harvest when most grains have turned golden, then dry the paddy to about 13 to 14 per cent moisture before milling or storage.
- Treat rice bran as a perishable feed ingredient. It turns rancid within weeks in warm storage, so buy it fresh and use it quickly.
Two rice systems and where each one works
Ask a farmer in the Upper East where his rice comes from and he will point at a valley, not a field. Lowland rice belongs to the inland valleys, the low ground where runoff collects, and to irrigation schemes built around dams and canals. Upland rice grows on the drier ground above those valleys, on slopes and on the forest-edge soils of the transition belt, and it lives or dies on the rain.
The real difference is water control. A lowland field can be flooded to choke weeds and feed the crop, then drained before harvest. An upland field gets whatever the sky decides to give it. That one fact sets the variety, the spacing, the fertiliser programme and how many hands you need in August. Walk the land after a heavy storm and watch where the water sits, and for how long, before you clear a single bush.
| Feature | Lowland (valley or scheme) | Upland (rain-fed) |
|---|---|---|
| Water | Held in the field and drained at intervals | Rain only, no standing water |
| Establishment | Puddled soil, transplanted seedlings or direct seeding | Drilled or broadcast seed on tilled dry soil |
| Main weed problem | Echinochloa grasses and sedges that thrive in wet soil | Grasses and broadleaf weeds that compete for moisture |
| Fertiliser response | Strong when water is managed well | Good in wet years, poor in dry spells |
| Biggest risk | Poor drainage, flood damage, broken bunds | Dry spell at flowering, bird and rodent damage |
Most growers who try rice for the first time start with a small lowland plot beside a stream or a seasonal pond. Once the bunds and drains are right, it is the more forgiving system. Getting there takes more labour in the first season, and that labour is the price of a field you can manage.
Bunds, water and puddling in the valley
A lowland plot lives or dies on its bunds. Build them before the rains start, not during the first downpour, and make them high enough to hold a few centimetres of water across the whole field. Check them after every heavy storm. One breach at the low corner can empty a plot overnight and leave the seedlings stranded on cracked mud.
Level the field as well as you can. Water settles unevenly on a bumpy plot, so the high patches dry out while the hollows drown young plants. A tractor with a levelling blade or a team with hoes will both do the job. The field is flat enough when you can see the water line move evenly across it.
Puddle the soil by ploughing or hoeing it when wet, then leave the water standing for a few days so the mud settles. Transplanting into soft, settled mud is far easier than pushing seedlings into hard ground. Keep the water shallow during the early weeks and deeper through the middle of the crop if your supply allows. Drain it a day or two before you top-dress or hand-weed, so you can walk the rows without sinking.
Watch the inlet as closely as the bunds
Water that comes in too fast carries silt and can wash out seedlings. Water that stops coming in during a dry spell turns the field to cracked clay by flowering. If your plot depends on a stream, a dam outlet or a canal, learn the release schedule from the people who manage it, and plan your transplanting around the day the water arrives.
Upland rice on the forest fringe and slopes
Upland rice is sown straight into the ground at the start of the rains. There is no nursery and no transplanting, which saves labour, but the crop has no reserve of water to fall back on. A field that gets no rain for two or three weeks around flowering can lose much of its grain, even when the leaves still look green from a distance.
Prepare the land early and clear the weeds before sowing. Many growers plough once, let the first flush of weeds come up, then kill it before drilling the seed. Sow in rows about 25 to 30 centimetres apart, which makes weeding and scouting easier than broadcasting. Use clean seed of a variety recommended for upland conditions, not grain bought from the market and sown because it looked good.
Choose a variety that finishes before the late-season dry spell in your area. Ask the district agric officer when the rains usually stop on your part of the forest fringe, then count back from that date. A variety that needs four months is no use if the rains quit in the third.
- Clear and plough before the first heavy rains.
- Kill the first flush of weeds, then sow.
- Drill the seed in rows rather than broadcasting where you can.
- Scout for birds and rodents during the first two weeks.
Upland fields often sit on lighter, more acidic soil than the valley floor, so the soil test matters more here. A poor stand on upland ground is usually a fertility or a water problem, and it rarely fixes itself with more seed.
Choosing a variety you can actually get seed for
The best rice variety on paper is useless if you cannot buy its seed. Ask three people before you purchase anything: your district agric officer, a seed grower in your area and a researcher at CSIR-SARI in Nyankpala, near Tamale. Between them they will give you a short list for your ecology. That list changes as new varieties are released, so check it every season rather than trusting last year's note.
In the northern lowlands, the Sahel series of varieties has been widely grown, including Sahel 108 and Sahel 177. For upland fields on the forest fringe, the NERICA types are the usual starting point. Both groups have a record of use in Ghana and the wider region, but they differ in height, duration and their response to water. Read the seed bag and the variety notes before you commit a hectare to one of them.
Plant certified seed wherever you can. Seed kept from your own harvest is cheaper, but it carries mixed grain and disease from the field it came from, and yields slip after a few seasons. Renew your seed every few seasons and keep the bag tag, so you can show a buyer or a cooperative exactly what went in the ground.
Varieties also differ in how they taste to the miller. A variety that cooks well and mills cleanly sells easier than one that breaks in the mill. Ask the millers in your area which types they want before you plant a big block, because a field of grain that nobody will buy is a poor field.
Nursery, transplanting and spacing
Seedlings for lowland rice come from a nursery bed about the size of a small room, kept wet and weed-free. Soak the seed overnight, drain it, cover it and let it sprout for a day or two before sowing. Sprouted seed comes up evenly, and evenly sized seedlings transplant evenly, which keeps the field growing as one crop rather than a patchwork.
Transplant at about 21 to 25 days, when the seedlings have three or four leaves and are still thin enough to lift without tearing the roots. Older seedlings do transplant, but they establish more slowly and give fewer tillers. Lift them with care, shake off the loose soil and tie them into small bundles for the walk to the field.
Plant two or three seedlings to a hill at a spacing of about 20 by 20 centimetres, which is a common starting point. Tighter spacing gives more plants per square metre but more competition for light and nutrients, and it makes weeding harder. Keep the rows straight with a string or a marker, so you can hoe between the lines later. Replant gaps in the first week, while the seedlings still have time to catch up with the rest.
A small thing that many first-time growers miss: plant on a day when the field is wet but not flooded, and set the seedlings shallow. Deep planting slows recovery after transplanting and gives weeds a head start in the open soil around the plant.
Feeding the crop without wasting fertiliser
Test the soil before you buy a single bag. A test costs far less than a season of guessing, and it tells you whether the field is short of phosphorus, potassium or nitrogen, or whether acidity is locking up what is already there. If a test is not possible, your extension officer can usually point you to a blend that suits your soil type.
Rice responds well to nitrogen, but a single large dose is wasted on a flooded field. Split it. Put a basal dose of compound fertiliser in at transplanting or sowing, then top-dress with urea in two rounds. The first round goes on a few weeks after transplanting, and the second a couple of weeks before flowering. Apply on a moist field, and drain the water first if your plan calls for it, so the fertiliser stays where the roots can reach it.
| When | What to do | Why it matters |
|---|---|---|
| At transplanting or sowing | Basal compound fertiliser, at the rate your soil test or extension officer gives | Gives young roots phosphorus and potassium while they establish |
| Three to four weeks after transplanting | First urea top-dress | Feeds tillering, when the plant sets how many stems it will carry |
| Two to three weeks before flowering | Second urea top-dress | Supports the number of grains each panicle can fill |
| Near flowering onwards | No more nitrogen unless the plant is clearly pale | Late nitrogen gives soft plants that lodge and attract disease |
Dried poultry manure can add nutrients to a rice field, but its strength varies a great deal from one shed to the next, so treat it as a supplement and not a substitute for a test. Our poultry manure fertiliser guide explains how to dry and apply it safely.
Weeds, stem borers and the birds that come for the grain
Weeds are the first enemy of any rice field, and the worst one is not always the weed you expect. Echinochloa grasses and sedges take over wet fields quickly. Weedy rice, the dark-grained relative that sheds its seed, can hide among the crop until it is too late to remove it. Pull off-type plants before they flower, and never save seed from a field that has them.
Scout the field every week, and walk the rows rather than looking from the bund. The yellow stem borer kills the centre of young tillers, leaving what growers call dead hearts, and later leaves whiteheads, panicles that fail to fill after flowering. Gall midge causes onion-leaf shoots that never produce a panicle. Rice blast shows as diamond-shaped spots on the leaves and sometimes on the neck of the panicle, and it is worst in cool, wet, cloudy spells. Follow your extension officer on any pesticide, and read the label, including the withholding period, before you sell or feed any straw or bran from the crop.
Birds are the problem most growers underestimate. Weaver birds and quelea flocks can strip a ripening field in days, especially where the open fields sit close to trees and villages. Scarecrows help only a little. A rota of people watching the field during the last three weeks before harvest does far more, and so does cutting the grass and bush along the edges of the plot, which removes the cover birds use to approach.
Rodents also take a share, especially on the upland fields and around the stores. Keep the bund clean, keep sacks off the floor, and set traps before the grain forms rather than after it is ripe.
Harvest timing, threshing and drying
Harvest when about 80 per cent of the grains on a panicle have turned golden. In most varieties that is roughly four to five weeks after flowering. Harvest too early and the grains are chalky and light. Wait too long, and the upland types begin to shatter, dropping grain into the field before the crew arrives.
Cut the plants close to the ground with a sickle and bundle them loosely so the grain stays together. Thresh the same day or the next, on a clean sheet or tarp, not bare earth, where stones and soil get mixed in. Beating bundles against a frame and using a mechanical thresher both work. The frame or drum must be clean, and the threshed grain should be fanned or sieved to remove chaff and dust.
Dry the paddy to about 13 to 14 per cent moisture before milling or storing it. Fresh harvest can come in at 20 to 25 per cent, so drying is not optional. Spread the grain thinly on clean mats or tarps and turn it often. Bring it in before dew and rain. Do not dry it on the road, where vehicles and animals leave dust, oil and worse on the grain. A moisture meter makes this easier, but a bite test and a feel test will tell you enough if you do them often.
- Harvest when most of the grain is golden, not when the whole field has browned.
- Thresh on a clean surface within a day of cutting.
- Dry to about 13 to 14 per cent before you store.
- Store in clean, dry bags stacked on pallets, clear of the walls.

What rice bran and husk mean for your poultry feed
This is where the rice field meets the poultry shed. Milling leaves bran, husk and broken grain, and many feed mixers use bran as a cheap source of energy and fibre. Rice bran carries a lot of oil, and that oil goes rancid within weeks in warm, humid storage. Rancid bran smells of old paint or stale crisps, and it cuts how much birds want to eat. Buy it fresh, store it dry, and get it into the mix within a few weeks rather than building a stock for the dry season.
Rice husk is a different product. It is coarse, dry and absorbent, which is why it is sometimes used as litter in poultry houses. Husk carries little nutrition, so it does not belong in the ration. Spread it in a thin, dry layer and turn it as the flock grows. Our wheat and rice bran guide covers how much bran a ration can take, and that limit is smaller than many farmers expect.
Rice straw is low in protein. Goats and cattle will eat it when they have nothing better, and it makes a fair bulk feed once it is mixed with a protein source. Poultry rarely need straw in the ration, but clean, dry straw is a reasonable bedding for a house, and that is a useful point for a mixed farm to remember.
If you already keep birds, the simplest link between the field and the flock is the manure. Measured, dried manure on the rice field returns nitrogen and phosphorus to the soil. Before you apply it, read our feed formulation basics so you know what the birds are actually eating, because the nutrient content of the manure follows the ration.
Many of the farmers who buy day-old chicks from us also grow a field of rice or maize, and the two share labour, manure and feed. The birds usually bring in the steady money, and the field is the buffer in the months when a flock is between batches. If you are planning both, start with the birds you can manage well and add the field once the shed is running smoothly.
Season calendar for the north and the valleys
The northern season runs with the rains, which usually start in April or May and stop around October. The south has a more complicated pattern, with a major and a minor rainy season, so use the calendar from your nearest MoFA office rather than a single rule of thumb. The table below shows a typical northern lowland programme. Move every date with the first reliable rain and the last safe harvest window.
| Period | Task in a lowland field |
|---|---|
| April to May | Soil test, bund repair, land clearing, nursery sowing |
| June to July | Puddling, levelling, transplanting, basal fertiliser |
| July to August | Weeding, first urea top-dress, bird and rodent watch begins |
| August to September | Second top-dress, water control, pest scouting |
| October to November | Drain the field, harvest, thresh |
| November to December | Dry, clean and store the grain before the harmattan |
The harmattan, a dry and dusty wind, blows from December into January. It helps paddy dry, but only if the grain is already dry when the wind picks up. Aim to finish harvest and drying before it sets in. Labour peaks at transplanting, the first weeding and harvest, so arrange family help or a hired team for those three windows well ahead of time.
Working out what a hectare costs before you plant
I will not give you a price for rice, seed, urea or hired labour. Those change with the market, the season and the district, and an old figure in an article will mislead you faster than no figure at all. What I can give you is the structure of the budget, so you can fill in your own numbers from the market and your suppliers.
Start with the inputs you buy: seed, basal fertiliser, top-dress, any pest control, bags, and fuel or hire for threshing. Add labour, counting every day you pay for or give in exchange. Add the cost of the land, whether it is rent, a share of the crop or your own plot. Then estimate the yield you expect. Use your own past records or the variety's recommended range, not the best field you have ever seen.
| Cost line | Quantity per hectare | Your price (from your supplier) | Line total |
|---|---|---|---|
| Certified seed | Per the variety recommendation | Fill in | Fill in |
| Basal compound fertiliser | Per soil test or extension advice | Fill in | Fill in |
| Urea top-dress (two rounds) | Per extension advice | Fill in | Fill in |
| Labour: nursery, transplanting, weeding, harvest | Person-days | Local day rate | Fill in |
| Threshing and drying | Hire or fuel hours | Fill in | Fill in |
Keep this sheet for every season. After two harvests you will know your real cost per bag, which is worth more than any average printed in a magazine. Our poultry record keeping guide uses the same method for birds, and the habit carries straight across to a field.
Who to ask about water, seed and money
If your plot sits inside an irrigation scheme or a valley committee, start there. Tono, Bontanga and Afife each keep their own water schedule, and the people who open the gates decide when you can transplant. Speak to them before the nursery goes in, not after the seedlings are standing in the bund with nowhere to go.
The district MoFA office is the second call. The extension officer for your community can confirm the variety list for your zone and tell you which grain the local millers want. A seed grower's bag is only as good as its source, so ask where the seed was multiplied, and check the answer against the advice from CSIR-SARI at Nyankpala.
For a loan to cover inputs, ask a rural bank and your district office what is available through GIRSAL-backed lending, and what security and repayment the lender expects. Ask what happens if the water fails. A rice loan that depends on a single season is tight for any household without a second income, so plan the repayment with that in mind. Check the current terms before you sign.
Rice and poultry share a holding well. The breeds page is the next stop for choosing birds, and our order form or WhatsApp at +233 24 915 1503 lets you talk it through first. We deliver across Ghana, and the delivery page shows what reaches your area.
If the same farm will also carry a dryland crop, read our guides to sorghum and millet in the north and cassava from planting to harvest. Each one needs different land, labour and a different calendar.
Questions farmers ask
Can I grow rice on land that floods for part of the year?
Yes, if the flood is shallow and drains away in time. Inland valleys that hold water through the rains are the classic lowland rice site. Deep floods that stay into the dry season are a problem, because they kill seedlings and delay planting. Walk the land after several storms, mark where the water sits, and ask a neighbour who has farmed the valley how long it stays. Your extension officer can help you judge whether the plot can be bunded and drained well enough.
Do I need irrigation to grow rice in Ghana?
Not always. Lowland fields in valleys can be grown on rainwater if the bunds hold the water through the season, and upland rice is rain-fed by design. Irrigation from a scheme or a dam gives you control over the timing of transplanting and drainage, and that control is worth a lot in a dry year. If you do not have an irrigation source, choose a variety recommended for rain-fed conditions and plan for the risk of a late or short season.
Which rice variety should I plant?
Ask the district agric officer for the current recommended list for your zone, then cross-check it with a seed grower and with CSIR-SARI in Nyankpala. Plant certified seed of a variety suited to lowland or upland conditions, depending on your land. Ask millers which types they buy, since a variety that breaks in the mill is hard to sell. Renew your seed every few seasons, because yield tends to fall when the same seed is saved for too long.
How much seed do I need for one hectare?
The answer depends on the variety and on the method. Transplanted fields use far less seed than broadcast or direct-seeded fields, because seedlings are raised in a nursery first and only the best are moved. The seed bag and your extension officer will give you the recommended rate for your variety. Weigh out a small test sample to check how much seed a metre of row takes before you buy the full quantity.
Is rice bran safe to feed to chickens?
Fresh rice bran can be a useful energy and fibre ingredient, but it is not a safe store-cupboard item. Its oil turns rancid within weeks in warm, humid conditions, and rancid bran reduces intake and can harm the birds. Keep it dry, buy it fresh and limit how much goes into the ration. Ask a feed formulator or your vet how much bran your flock can take, because the right amount depends on the birds' age and the rest of the ration.
Why did my rice turn yellow in the middle of the season?
Yellowing usually points to one of four problems: too little nitrogen, waterlogging or poor drainage, heavy weed competition, or disease. Check the field in three places, look at the roots and the water level, and compare the pale patches with the drier or wetter spots. If the whole field is pale and the top-dress was late or missed, nitrogen is the likely cause. Your extension officer can confirm the cause before you spend on a remedy.
When should I plant rice in northern Ghana?
Plant with the first reliable rains, which usually come in May or June across the north. Transplanting from a nursery sown in May tends to fit the June and July window, and direct seeding on upland fields follows the first steady rains. Confirm the date with your local MoFA office, because the start of the rains varies by a few weeks from one district to the next. The aim is to have the crop flowering in the wettest weeks and harvesting before the harmattan.
