How to grow finger millet

Ask the dealer for treated (dressed) seed — seed coated with a fungicide (a medicine that kills disease-causing fungus) — or clean certified seed of a named variety, because blast rides on the seed itself.

If you must use your own seed, take it only from a healthy crop that had no whiteheads last season, and treat it with a seed dressing before you sow.

Match the variety to your place: finger millet grows higher and drier than maize, so pick a short-season type where the rains are short, and check your recommendation.

Buy only a small amount of basal (starter) fertiliser — this crop feeds lightly and mainly wants a little phosphorus (P) to build roots. Your recommendation gives the amount. Do not buy heavy nitrogen for basal.

Store seed and fertiliser dry, up off the floor, away from food, water and children, and keep the label and receipt in case the seed turns out poor.

Plough or dig early, in the weeks before sowing, then break every clod down small — rub a handful and it should crumble into fine crumbs, not lumps.

Clear out stones, roots and old weeds so the tiny seed meets bare, fine soil with nothing in its way.

Firm the bed — press it down with a plank, a light roller, or your own feet — so it is firm underfoot, not fluffy; the tiny seed needs soil pressed close around it.

Level the surface so rain spreads evenly and does not wash the light seed into heaps. On a slope, work across the slope to hold the soil and water.

About 3–4 weeks before you plant out, pick a small, well-drained patch near water and make the soil very fine and firm, just like the main bed.

Water the bed, then sow the tiny seed thinly — first mix it with a few handfuls of dry sand or ash so it spreads instead of falling in clumps.

Cover with only a whisper of fine soil (about one finger-joint, ~1 cm) and firm gently; shade or lightly mulch until the seedlings show, then take the cover off.

Keep the bed moist but never soaked — soggy, crowded beds rot the seedlings off at the soil line (damping-off). They are ready to move at about 3–4 weeks, when they stand roughly a hand-span tall (~20 cm).

Sow as soon as the seedbed is moist from a good planting rain — the tiny seed must go into damp, warm soil to catch.

Line-sow, never broadcast. Open shallow furrows about a hand-span apart (≈25 cm) — scattering seed loose everywhere triples the weeding, because you can no longer tell the crop rows from the weeds.

Because the seed is dust-fine, mix it with dry sand or ash (a few handfuls) and trickle the mix thinly along each furrow so it spreads evenly.

Cover only 1–3 cm — one finger-joint at most; any deeper and the tiny seedling never reaches the light. Firm the soil over it for good contact.

If transplanting instead: lift your 3–4-week nursery seedlings (bed watered the night before) and set them a hand-span apart (≈25 cm) between rows and half a hand-span (≈10 cm) along the row, at the depth they grew, then firm and water them in.

Walk the field every 2–3 days right through the first three weeks after sowing, looking down the rows.

Crop or weed? Finger millet sits in your straight sown rows and stands a little stiffer and darker; goosegrass, the look-alike weed, is limper, paler, and sprawls flat between the rows. Anything off the row line is almost always weed.

Seedling blast: look on the little leaves for small grey, spindle- or diamond-shaped spots with brown edges, and mark where you see them.

Gaps: note bare patches where seedlings have rotted and toppled at the soil line (damping-off) — usually the wettest, most crowded spots.

Write down what you find, and act at the next weeding — or sooner if blast is spreading. If blast keeps spreading in wet weather, keep nitrogen light and be ready to spray once the heads come out (see the blast-spray task).

Weed by about 15–20 days after sowing (2–3 weeks), before the weeds grow taller than the crop — this one window is worth up to 70% of your harvest.

Tell crop from weed first: the crop is in your straight rows and stands stiffer and darker; goosegrass is limp, pale, and sprawls off the row. When unsure, leave whatever is sitting on the row line.

Weed shallowly with a hand hoe or by hand, between and within the rows — deep hoeing tears the crop's shallow roots.

Pull the weeds right out, roots and all; in dry areas leave them lying between the rows as a light mulch to hold moisture.

Keep the topsoil just moist through the first ~3 weeks after sowing — the seedlings root shallow and dry out fast.

Water lightly every 4–7 days, more often on sandy soil or in heat; push a finger in and water when the top few centimetres are dry.

Water gently — a hard flow washes the tiny seedlings and light seed into heaps and leaves bare patches.

Walk the field every 3–4 days from about 3 to 6 weeks after sowing, checking the leaves, the base of the plants, and the central shoots.

Leaf blast: grey, spindle- or diamond-shaped spots with brown edges on the leaves — worse in wet, lush, over-fed crops.

Striga (witchweed): small purple- or pink-flowered weeds coming up near the crop base, with the crop around them stunted and yellow even where you have fed it — Striga is robbing it from below ground.

Stem borer: the central leaf whorl dries and dies while the outer leaves stay green (this is called a 'dead-heart') and pulls out easily — caterpillars are tunnelling inside the stem.

Note what you find, then hand-pull Striga now, keep nitrogen moderate against blast, and cut and destroy any borer-hit shoots. If Striga keeps coming back, plan a legume rotation next season to run down its seed in the soil.

Weed again at about 30–35 days after sowing, before the crop closes over and shades the ground for itself.

Hoe shallowly between and within the rows; the crop's roots now spread near the surface.

Time it just before you top-dress nitrogen, so the feed goes to the crop and not to the weeds.

Pull out any Striga you meet as you weed (see the hand-pull-Striga task).

Top-dress nitrogen at about 25–35 days after sowing, when the crop is starting to throw side-shoots (tillers) — ideally straight after the second weeding.

Use only the modest amount your recommendation gives — this is a low-feeding crop, and more is not better.

Band it to the side of the row, about a hand's width (≈10 cm) off the plants, never on top of them — fertiliser sitting on the crop scorches it.

Feed onto moist soil (after weeding or a light rain) and lightly cover it, so the rain does not wash it away and the sun does not gas it off.

From about 3 weeks after sowing, check every 7–10 days for small purple- or pink-flowered weeds near the crop base.

Pull them out by hand before they flower and seed — once they flower they may already be dropping seed.

Carry them off the field and burn or bury them — never leave them lying and never put them in compost; the seeds survive.

Where Striga is bad, plan a legume rotation (cowpea, groundnut) next season — legumes make Striga seeds sprout with no crop to attack, so they die off (a 'trap crop').

From the moment the heads emerge, walk the field every 2–3 days — this is the tightest watch of the whole season.

Neck blast: look at the neck just below each head for a brown-black rot; above it the head turns pale and white (a 'whitehead') and stays empty.

Finger blast: look on the fingers themselves for dark, brown-black rotten patches among the developing grain.

Rogue (pull out) and carry off and burn any whitehead or neck-blast plant you find — do not leave it standing to seed the disease.

If blast is showing and the weather is wet, spray at heading (see the blast-spray task) and write down the date so you know when to repeat.

Spray at heading, when the fingers are out, if the weather is humid or rainy and you are seeing blast — this is the payback window.

Use an approved fungicide ('fungicide' = a medicine that stops fungal disease). Measure the dose with the cap supplied and mix it into a full knapsack (15–20 litres).

Spray to wet the leaves and heads evenly, without letting it drip off.

Repeat once, about 15 days later, if the weather stays wet; in a dry spell one spray — or none — may be enough.

Safety: wear a long-sleeved shirt and cover your nose and mouth, spray in the cool of the day with the wind behind you, keep people and animals away, keep it off food and water, wash yourself and the sprayer afterwards, and wait the number of days the label states before you harvest — this wait, the 'pre-harvest interval', lets the spray fade before the grain is eaten.

Keep the soil moist right through flowering — water every 5–7 days, more often in heat.

Do not let the crop wilt while the fingers are flowering; this is the one stage where water pays back most.

As flowering finishes, taper the water off — finger millet needs a dry finish to ripen cleanly and store well.

Make sure the field drains — heavy standing water at flowering also cuts the grain set (this is waterlogging).

Start guarding at soft-dough — squeeze a grain and it is still soft and pasty inside (about 75 days after sowing) — and keep on right up to harvest.

Guard from dawn to dusk every day; birds feed hardest in the early morning and the late afternoon.

Use noise and movement: shout, bang tins, crack a whip, hang rattling strips and flags, and keep a scarecrow that you move about.

Work with your neighbours — if you all scare at once, the flocks cannot just shift from one field to the next; guard alone and they all land on you.

Once a week, from about 70 days after sowing, walk the field and look over the heads as they fill and turn brown.

Neck blast on late heads: spot any whitehead — a head gone pale and empty above a brown-black rotten neck.

Rogue (pull out) and carry off and burn every whitehead — especially if you plan to save seed, since blast rides on the seed into next year.

Note whether the crop is drying evenly toward harvest — heads browning, lower leaves dried.
