Simple notes for farmers

About the crop: This crop is annual. You plant, grow and harvest it in one main season, then plant again. You can normally start harvesting about 90-180 days after planting, depending on care and variety.

Main use: Farmers mostly grow this crop for forage; pasture; hay.

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: Temperate regions It is grouped under: Forages & Fodder.

Best climate: This crop does well in warm areas where the temperature is usually between 10 and 20 degrees Celsius. It prefers places that receive around 700 to 1000 millimetres of rain in a year. It can grow from near sea level up to about 2600 metres above sea level.

Soil: The crop grows best in slightly acidic to near neutral soils, with a pH of about 6 to 6.8. It does well in fertile, well-drained loam. Good drainage is important, so avoid waterlogged spots.

Plant spacing: Plant in rows about 20 centimetres apart, and leave about 5 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 1.5 centimetres deep so the roots sit firmly in the soil but are not buried too deep.

Seed or planting material: Use around 25 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: Direct-seed Ryegrass into a fine firm seedbed at onset of reliable rains.
Transplanting: Not transplanted.
Irrigation: Maintain moisture during establishment and grain filling where irrigation is used.
Fertigation: Split nitrogen between planting and early vegetative growth where moisture allows.
Pest scouting: Scout Ryegrass for aphids, armyworms, foliar diseases, and lodging risk.
Pruning: No pruning needed; keep weeds low during early establishment.
Harvest: Harvest Ryegrass when grains harden and heads dry down evenly.
Postharvest: Dry grain well before threshing and storage.
