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 365 days after planting, depending on care and variety.
Main use: Farmers mostly grow this crop for fiber crop for ropes, twines, and industrial biomaterials..
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: Traditional cash crop in arid and semi-arid coastal East Africa. It is grouped under: Oil & Industrial.
Best climate: This crop does well in warm areas where the temperature is usually between 20 and 34 degrees Celsius. It prefers places that receive around 500 to 1200 millimetres of rain in a year. It can grow from near sea level up to about 3000 metres above sea level.
Soil: The crop grows best in slightly acidic to near neutral soils, with a pH of about 6 to 7. It does well in well-drained loam to clay loam with moderate fertility.. 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 4 centimetres deep so the roots sit firmly in the soil but are not buried too deep.
Seed or planting material: Use around 80 kilograms of seed or planting material per hectare. Spread or plant evenly so the field has a good stand without being overcrowded.
