Growing Okra in Ghana: Direct Sowing to Daily Picking

Pods that turn to fibre overnight and why picking time matters

Ask any market trader why her okra is going soft and stringy, and she will tell you the pods were left on the plant a day too long. Okra is one of the few crops where the difference between a tender pod and a tough one can be a single day in hot weather. A pod picked at the right size sells quickly and cooks well. The same pod left on the plant for a week becomes woody and bitter, and the buyer walks away.

Okra is outside our trade: we hatch day-old chicks at Opeikuma, near Kasoa. We write about it because many poultry keepers want a crop to grow beside the pen, and okra is one of the more forgiving options. Okra fits that picture well. It is a warm-season crop with a long harvest, it responds to manure and compost, and it gives a steady income once the first pods come.

This guide follows the crop from the sowing to the sale. The points that decide the quality of the pods come early, in the sowing, the thinning and the pest scouting, so they get the most attention here.

Planting for warmth: when okra goes in across the zones

Okra does not like cold. Seed sown into cool, wet soil rots before it germinates, and young plants stall in cold nights. Sow once the soil is warm and the rains have settled, rather than on the first shower. In the north, that usually means the start of the rains, around May or June. In the forest and coastal zones, the major-season crop goes in during March and April, and a minor-season crop can go in during August and September. Where water is available, dry-season okra can be grown under irrigation, though the pods may be smaller in the hottest weeks.

The table below gives a typical planning guide. Your own rainfall pattern will move the dates, so check the calendar with your district extension office before you buy seed in quantity.

Okra likes a sunny spot with good drainage. A field that holds water after rain will rot the seed and the roots, and a very sandy patch will dry out too quickly unless you mulch it.

Spineless lines, local selections and seed that actually germinates

Growers choose between spineless and spiny types, and most now prefer spineless lines, because the spines on the pods and stems make harvesting slow and scratchy. Clemson Spineless is a widely grown open-pollinated line in many tropical countries, and it is a common reference point for growers. Ask local seed suppliers whether they stock it or a locally tested equivalent. Ask which lines have been tested in your zone, and check the packet for open-pollinated or hybrid, since that decides whether you can save seed from your own plants.

Okra seed loses its vigour quickly in heat and humidity. Buy fresh seed each season, keep unused packets in a cool, dry tin, and check germination before you commit a large area. A quick test is to place ten seeds on damp cloth in a covered dish for a few days and count how many sprout. If fewer than eight do, plant more seed per hole or buy a fresher lot.

Saving seed is possible, but only from healthy, true-to-type plants. Leave a few of the best plants to form mature pods, let the pods dry on the plant until they split, then store the seed in a dry, sealed container. Mixing types in the same field makes saving seed unreliable, so keep your seed plot apart from any other okra.

Sowing, thinning and the spacing that gives the most pods

Okra is best sown directly into the field. Its taproot resents disturbance, and transplanted okra often sulks for weeks. If you must raise seedlings in bags or pots because the ground is still cold, sow them young and plant them out with the roots intact and without delay. For direct sowing, make holes about two centimetres deep, put two or three seeds into each hole and cover them lightly. Soaking the seed in water overnight speeds germination, which usually happens in five to ten days in warm soil.

Thin to one plant per hole once the seedlings have two true leaves, and pull out the weakest. Do not leave extra plants crowded together, because they compete for water and light and produce thin, short pods. Replant any gaps in the first week using seed you have soaked and kept in reserve.

Spacing is 60 cm between rows and 30 cm within the row. That gives about 55,000 plants on a hectare, a good density for a crop that branches and flowers over a long season. A wider spacing of 75 cm between rows, with the same within-row distance, gives more room for walking and picking, and it reduces the humidity between plants. Ridging the bed slightly helps drainage, and it makes watering easier for hand-watered plots.

Feeding and watering through the flowering stage

Okra is not as hungry as cabbage or tomato, but it still responds to good nutrition. Compost or well-rotted manure worked into the bed before sowing gives the plants a steady supply of nutrients through the season. A light nitrogen top dressing about four weeks after sowing supports leaf growth, and a balanced feed around flowering helps the pods fill. Too much nitrogen gives a big, leafy plant with fewer pods, so match the feed to what the plants are producing rather than to a calendar.

Water is the bigger constraint. Okra tolerates dry spells better than many vegetables once the plants are established, but it needs regular moisture from flowering onwards, when the pods are forming. A plant that dries out at flowering drops buds and produces short, twisted pods for the rest of the season. In the north, plan irrigation for the flowering period in particular, and mulch to hold the soil moisture between waterings.

Keep the bed clean of weeds for the first six weeks. Once the canopy closes, the okra shades out most of the weeds, but the early weeds compete hard for water and nutrients when the plants are small.

Earias: the shoot and fruit borer you will find by its holes

Earias larvae are the pest that decides most okra yields in Ghana. The caterpillars bore into the growing shoot tips and then into the young pods, leaving small round holes and a little frass near the entry point. A shoot that wilts and dies back at the top, or a pod with a neat hole and a dark mark beside it, is the sign. Once the larva is inside, a spray does little good, because the caterpillar is protected by the plant tissue.

Scout the shoot tips every few days from the first flower. Look for wilted tips, holes in the stem and the first pods. Cut out an infested shoot below the damage and bin it, and pick affected pods off straight away rather than leaving them to shelter the next generation. Do this early, while the caterpillars are still few, because the damage builds up quickly during the warm weeks.

Some growers use pheromone traps or light traps to monitor moth numbers, and where those are available through the extension service, they help you time your scouting. Products registered by the Plant Protection and Regulatory Services Directorate for okra can be used as part of a programme, but they should be applied on the basis of scouting, following the label closely, including the waiting period before harvest. Your extension office can name the borer for you, which matters before you buy a product.

Jassids, whitefly and the yellow-vein virus they carry

Jassids are small green leafhoppers that jump when you disturb the plant. They pierce the leaves and suck the sap, and the leaf edges turn yellow, cup and burn. In a bad attack the plant stops growing and the leaves look scorched at the margins. Check the undersides of young leaves on ten plants a week, and look for the hopping insects when you brush the foliage.

Whitefly is the more serious problem because it carries a virus. Okra Yellow Vein Mosaic Virus shows as yellow veins on the leaves, which spread into a network of yellow over the leaf, and the plant becomes stunted with small, poor pods. Infected plants do not recover, so the strategy is to stop the whitefly early and to pull out plants that show the yellow-vein pattern rather than leaving them to infect their neighbours.

Keep the bed free of weeds that host whitefly and jassids, including wild hibiscus and other malvaceous weeds near the field edge. Yellow sticky traps set at canopy height help you monitor the whitefly build-up, and they give you a clear signal when to start checking the plants more closely.

• Pull out and bin plants that show yellow-vein symptoms as soon as you see them.
• Keep weeds at the field edge short, since they host the sap feeders.
• Use only products registered for okra in Ghana, and check the label for the sap feeders you are targeting.
• Rotate products with different modes of action if spraying is needed more than once.

Root-knot nematodes and the sandy-ground problem

Root-knot nematodes are microscopic worms that live in the soil and enter the roots of okra. The roots form galls, or knots, which interfere with water and nutrient uptake. A plant with root-knot damage looks stunted and yellow, wilts in the afternoon and yields poorly, even when the water and feed are right. The problem is worst on light sandy soils, which warm quickly and let the nematodes move through the profile.

Pull a plant with a gentle hand and look at the roots. Small swellings or knots on the root tips and along the root system are the sign. Once the nematodes are established in a field, they stay there for several seasons, so the aim is to avoid building up the population in the first place. Keep the field free of susceptible weeds, rotate okra with a non-host crop where you can, and add well-rotted compost, which encourages the microbes that compete with nematodes.

Some growers use resistant varieties where they are available, and others use tagetes or other cover crops between seasons, though the evidence for each depends on local conditions. Ask your extension officer about the options that have been tested in your region, and do not assume that a single trick will solve a heavy infestation. Our garden eggs guide covers how the same soil pests show up in a close relative of okra, and what helps there.

Powdery mildew, leaf spot and the damping off of young seedlings

Fungal diseases of okra show up in two very different ways. Damping off hits the seedlings in wet soil, where the stem collapses at soil level and the plant falls over. The remedy is simple: sow into warm, well-drained ground, avoid overwatering the young seedlings, and thin them so the air can move.

Powdery mildew appears as a white, powdery coating on the upper surface of the leaves, usually towards the end of the rains or in the early dry season, when humidity and temperature swing. It reduces photosynthesis and can weaken the plant before the pods have filled. Cercospora leaf spot shows as small, round, grey-brown spots with a darker ring. Both diseases are easier to manage with good spacing, weed control and removal of the worst-affected leaves, than with routine spraying.

Fusarium wilt is a soil-borne problem that yellows and wilts plants from the bottom upward, and it stays in the field. Do not replant okra on a bed where it has shown up, and remove infected plants with their roots. Rotate the bed out of okra and related crops for at least two seasons, and use clean seed from a trusted source.

Picking every other day and keeping the pods tender

The harvest is where okra earns its keep. Pods are ready to pick roughly four days after the flower opens, when they are 6 to 10 cm long and still tender enough to snap cleanly. Check the bed every one or two days in the peak weeks, because a pod that is missed for a week will grow fibrous, and it will not sell. In hot weather the crop can set pods faster than you expect, so the rhythm matters more than the calendar.

Pick with a sharp knife or by snapping the stalk cleanly, and avoid tearing the plant. Wear gloves or sleeves if the pods are hairy, because the fine hairs irritate the skin. Put the pods straight into shallow baskets, and move them into shade. Okra wilts within hours in the sun, and a basket left on the ground in direct heat loses its firmness fast.

Keep the first pods separate from the late ones if you want to grade the crop, because the early pods tend to be more tender and command a better price in the fresh market.

Selling fresh, drying for soup and keeping seed

Okra sells fresh in bundles, bowls or baskets, and traders in the central markets buy in bulk for restaurants and households. The fresh trade is fast and seasonal, and the quality is judged by the colour, the firmness and whether the pods are free of holes and marks. Sell the tender pods the same day, and keep the rest cool and out of the sun until they move. Okra kept in a hot room for two days loses both weight and texture.

Dried okra gives you a second market. Slice the pods thinly or dry them whole on a clean mesh in the sun, bringing them in each evening, until they are brittle and snap. Store the dry pieces in an airtight container, away from damp and insects, and check them every month. Dried okra and okra powder keep for months and suit cooks who want the flavour outside the season. Be sure to dry the pods completely before storage, because damp okra mouldy quickly.

Demand for okra rises in the festive weeks, when families cook large pots of soup and stew, and when restaurants prepare more traditional dishes. Plan your sowing so the main harvest runs into those weeks rather than finishing before them. For current rates, check your local market on the day you sell, and ask two or three regular buyers what they paid for the last lot. Prices move with the season and the supply, so a figure from last year is a poor guide.

Many of the traders who buy okra also buy pepper, so a bed of both can share one trip to market; our pepper and chilli guide explains that crop's timing. Chopped okra stalks and the leaves from the thinned plants can go into the compost heap. The woody stems take longer to break down, so chop them finely before they go on the heap.

A checklist for the okra bed from sowing to sale

Use this list each season, and mark off each step as you complete it. Most of the losses in okra come from skipping the scouting, not from any single hard task.

1. Choose a spineless line tested for your zone and check the germination of the seed.
2. Sow once the soil is warm and the rains have settled, at 60 by 30 cm.
3. Soak seed overnight, sow two or three seeds per hole, and thin to one plant at two true leaves.
4. Apply well-rotted compost before sowing and a light top dressing about four weeks later.
5. Keep the bed weed-free for six weeks and mulch in the dry months.
6. Scout the shoot tips and young pods for Earias holes every few days from first flower.
7. Check undersides of leaves weekly for jassids and whitefly, and pull out yellow-vein plants.
8. Pick every one or two days at 6 to 10 cm and keep the harvest in shade.
9. Dry the surplus pods completely before storage, and keep seed plants apart.
10. Write down the sowing date, the first picking and the sales, so next season starts from facts.

Okra and poultry share a lot of practical ground. Chicken manure is a good feed for the bed, and the beds give the birds a place to scratch. Our poultry manure guide explains how much to use and how to compost it first, and the composting article covers the heap. For a broader view of where the crop fits, the integrating poultry with crops and fish article shows how the parts link together on one farm.
