  • The acronym TME 419 refers to a specific variety of cassava ( Manihot esculenta Crantz). It's a popular and significant variety, particularly in West Africa, including Nigeria, and is known for several important characteristics:
  • Key Characteristics of TME 419 Cassava:
  • High Yield Potential: TME 419 is capable of producing significantly higher yields per hectare compared to many traditional cassava varieties. Reports suggest potential yields ranging from 20-35 tons per hectare under good management practices.
  • High Dry Matter Content: This variety is favored for its relatively high dry matter content. This is crucial for processing into products like garri and fufu, as it translates to a higher yield of the processed product from fresh roots. Dry matter content can be around 25-40%.
  • Good Starch Quality: The starch derived from TME 419 has desirable qualities for both food and industrial uses. For fufu, it provides a smooth and elastic texture. For industrial purposes, the high starch content is valuable.
  • Resistance to Cassava Mosaic Disease (CMD): TME 419 exhibits good resistance to CMD, a major viral disease that can severely reduce cassava yields. This disease resistance contributes to more stable and reliable harvests.
  • Manageable Cyanogenic Potential (CNP): While not entirely "sweet," TME 419 has a level of naturally occurring cyanide that is considered manageable and safe for consumption after standard processing methods like grating, fermenting, and drying used in the preparation of garri and fufu. Reported CNP levels are relatively low.
  • Adaptability: TME 419 is known for its adaptability to various agro-ecological zones within Nigeria and other West African countries, making it suitable for cultivation in diverse soil types and climatic conditions.
  • Early to Medium Maturity: It typically matures within 9-18 months, allowing for relatively quicker harvests compared to some longer-duration varieties.
  • Plant Morphology: The plant typically has deeply lobed leaves (5-7 lobes) that are dark green. The stem is usually green with reddish or purplish tinges, especially at the nodes, and has an upright growth habit. The roots are generally large, cylindrical or slightly tapering, with brown or light brown skin and white or cream flesh.
  • TME 419 Cassava Stems:
  • Cassava is propagated vegetatively using stem cuttings. Therefore, "TME 419 cassava stems" are the cuttings taken from mature TME 419 plants and used for planting new crops.
  • Farmers select healthy stems, typically 2-4 cm thick and about 20-30 cm long (with 4-7 nodes), from disease-free TME 419 plants for propagation.
  • These stems are planted either horizontally or vertically in prepared soil, and new plants sprout from the nodes.
  • The availability of quality TME 419 stems is crucial for farmers looking to cultivate this high-yielding and disease-resistant variety.
  • In summary, TME 419 is a highly valued cassava variety in Nigeria and West Africa due to its high yield, good processing qualities, disease resistance, and adaptability. "TME 419 cassava stems" are the essential planting material for growing this important crop.
