NOTE

CHARACTERISTICS OF PASTURE GRASSES LEGUMES

Characteristics of Pasture Grasses and Legumes:

  1. Pasture grasses and legumes exhibit varying degrees of adaptability to different soil types, climates, and management practices.
  2. These plants provide essential nutrients such as protein, carbohydrates, vitamins, and minerals, which are important for the growth and development of grazing animals.
  3. Palatability refers to the attractiveness of grasses and legumes to grazing animals. Some species are highly palatable and preferred by livestock, while others may be less palatable.
  4. The digestibility of pasture grasses and legumes affects their nutritional value and utilization by grazing animals. Higher digestibility leads to better feed conversion and animal performance.
  5. Persistence refers to the ability of grasses and legumes to withstand grazing pressure, environmental stress, and competition from weeds.

Examples of Pasture Grasses include:

  1. Guinea Grass (Panicum maximum): A tropical grass species known for its high productivity, palatability, and tolerance to grazing and drought conditions.
  2. Elephant Grass (Pennisetum purpureum): A tall, coarse grass species with high biomass production and tolerance to flooding, commonly used for cut-and-carry systems and silage production.
  3. Bahama Grass (Paspalum notatum): A warm-season perennial grass with good drought tolerance and persistence, often used for grazing in subtropical regions.
  4. Northern Gamba Grass (Andropogon gayanus): A tall, tufted grass species adapted to tropical climates, known for its rapid growth and high forage yield.
  5. Giant Star Grass (Cynodon plectostachyus): A warm-season perennial grass species with excellent drought tolerance and grazing persistence, commonly used in tropical and subtropical regions.
  6. Spear Grass (Heteropogon contortus): A native grass species with good drought tolerance and grazing value, often found in mixed grass-legume pastures.

EVALUATION: 1. Mention 5 characteristics of pasture grasses and legumes.

  1. Describe briefly 5 examples of pasture grasses .
