(1b)
=Nitrogen (N)=
– Promotes leaf growth and development
– Essential for protein synthesis
– Necessary for chlorophyll production

=Phosphorus (P)=
– Important for root development and growth
– Necessary for flower and fruit formation
– Involved in energy transfer and storage

=Potassium (K)=
– Helps regulate water balance and transport
– Essential for stem and root growth
– Involved in photosynthesis and sugar production

(1c)
TABULATE

=SPECIMEN A=
(i) It appears as granules or pellets, often with a uniform size and color.
(ii) It has little to no smell
(iii) It provides a quick and readily available source of nutrients (nitrogen, phosphorus, and potassium) to plants.

NUMBER 2

(2a)
C. Guinea grass – Panicum maximum
D. Elephant grass – Pennisetum purpureum
E. Centrosema – Centrosema pubescens
F. Calopo – Calopogonium mucunoides

(2b)
(i)High protein content: Centrosema is a legume that fixes nitrogen, making it a valuable addition to pastures, providing a natural source of protein for livestock.
(ii)Drought tolerance: Centrosema is relatively drought-tolerant, making it a suitable choice for pastures in areas with limited rainfall.
(iii)Palatability: Centrosema is a palatable forage crop, meaning it is readily consumed by livestock, improving their overall nutrition and productivity.
(iv)Weed suppression: Centrosema can outcompete weeds, reducing the need for herbicides and improving the overall health and productivity of the pasture.

(2c)
-Harvesting: Cut the forage crop (e.g., maize, grass, or legumes) at the appropriate stage of maturity.
-Wilting: Allow the cut forage to wilt for a few hours to reduce its moisture content.
-Chopping: Chop the wilted forage into smaller pieces to facilitate fermentation.
-Mixing: Mix the chopped forage with other ingredients (e.g., molasses, salt) to create a uniform blend.
-Filling: Fill a silo or storage container with the mixture, ensuring it is tightly packed to exclude air.
-Compaction: Use a machine or manual compaction to remove any air pockets and ensure the mixture is densely packed.
-Sealing: Seal the silo or container to prevent air from entering and spoiling the silage.
-Fermentation: Allow the mixture to ferment for several weeks or months, depending on the desired level of fermentation.
-Feeding: Once the silage has fermented, it is ready to be fed to livestock.
