Simple notes for farmers

About the crop: This crop is perennial, which means once you plant it, the same plant can keep producing for many years. You can normally start harvesting about 120–365 days after planting, depending on care and variety.

Main use: Farmers mostly grow this crop for forage grass for cut-and-carry, pasture, hay/silage.

Pollination: This crop is mainly pollinated by wind. Keeping flowers healthy and having insects like bees in the field helps improve fruit set and yields.

Where it grows: Tropical Africa & South America; widely adopted in East Africa It is grouped under: Forages & Fodder.

Best climate: This crop does well in warm areas where the temperature is usually between 20 and 30 degrees Celsius. It prefers places that receive around 700 to 1500 millimetres of rain in a year. It can grow from near sea level up to about 2000 metres above sea level.

Soil: The crop grows best in slightly acidic to near neutral soils, with a pH of about 5.5 to 6.8. It does well in well-drained loam to sandy loam; tolerates low fertility with management. Good drainage is important, so avoid waterlogged spots.

Plant spacing: Plant in rows about 50 centimetres apart, and leave about 50 centimetres between plants in the row. This gives each plant enough space for roots and canopy to spread.

Planting depth: Dig planting holes or furrows about 2 centimetres deep so the roots sit firmly in the soil but are not buried too deep.

Seed or planting material: Use around 6 kilograms of seed or planting material per hectare. Spread or plant evenly so the field has a good stand without being overcrowded.

Farmer guide (mwongozo wa mkulima)

Planting: Plant at onset of rains. For splits, plant 1–2 tillers per station in moist soil; for seed, drill/shallow cover and firm soil. Control weeds during establishment.
Transplanting: Not typical; use vegetative splits or direct seeding.
Irrigation: Ensure moisture during establishment and after each cut; avoid waterlogging.
Fertigation: If irrigated, supply N in small doses after cuts to boost regrowth.
Pest scouting: Scout for spittlebugs and leaf spots; maintain field hygiene and balanced nutrition.
Pruning: Cut at 15–20 cm stubble to protect crowns and encourage tillering.
Harvest: First cut ~8–10 weeks after establishment; subsequent cuts every 4–6 weeks at 30–40 cm height or early boot stage.
Postharvest: For hay, wilt to ~85% DM before baling. For silage, chop 2–3 cm and ensile at ~30–35% DM.
