Scientific name: Panicum maximum cv.Mombasa
Productivity: Mombasa guinea grass is a tall grass, similar to hybrid Napier grass in habit, but far more leafy and is very suitable for cut-and-carry. It is a very productive leafy grass, producing between 20 and 40 t/ha dry matter per year.
Crude protein levels: Mombasa guinea grass 8-12% crude protein in Thailand on poor soils and 12-14 % crude protein on better soils.
Animal production: No data fromThailand, but inSouth America, liveweight gains of 770 kg/ha/yr compared with 600, and 590 kg/ha/yr from Purple Guinea and Tobiata guinea grass. It is more productive than Guinea TD58 (Purple guinea).
Grazing management: Mombasa guinea grass Can be either rotationally grazed or set stocked. Management depends on the farmer’s experience. Most farmers in South America prefer cut-and-carry. Therefore cut every 40-45 days in the wet season and 60-70 days in the cool season.
Establishment: Mombasa guinea grass Can be either planted in rows, 50 cm apart, or broadcast sown at 6-8 kg/ha. Sow the seed on to the soil surface, brush the seed with soil by using tree branches or large brooms. Bury the seed no more than 1-2 cm under the soil. It is easy to plant from rooted tillers.
Background: It was introduced into Brazil from Tanzania in 1993, from near Korogwe, Tanzania (5.20°S 38.50°E, 290 m asl, rainfall 1,050 mm). Large tussocks to 2 m, stems tinged with purple. Leaves are long, to 3 cm wide, with short hairs on the upper surface; leaf sheaths are glabrous. Good drought and cold tolerance. Dry matter yield 28% more than that of Guinea TD58 (purp
Seed: Seed produced inThailand is harvested by hand and has a purity of over 98%. It is pure-to type with no other guinea grass seeds in Mombasa seed fromThailand.le guinea).
A lot of farmers tie the seed heads together and then lie the seed heads down along the rows. This makes harvesting easier and also if strong winds occur, less seed gets blown off.
In one village the farmers have invented a special cart to collect the seed. This is pushed along underneath the seed heads down the rows. In one photo you will see the cart pushed under the seed heads but this was only a demonstration. There was no cloth tied on the cart. They will start harvesting today in that particular field and the blue cloth will be tied over the cart frame.
