(2a)

(Pick Any FOUR)

(i) Broadcasting: spreading the fertilizer evenly over the soil surface and then incorporating it into the soil with a cultivator or tiller.

(i) Banding: placing the fertilizer in narrow bands alongside the plants or seeds, which allows for more efficient uptake by the roots.

(iii) Side-dressing: applying the fertilizer to the soil in a band near the plants at a later stage of growth.

(iv) Foliar application: spraying the fertilizer solution directly onto the leaves of the plants.

(v) Drip irrigation: incorporating the fertilizer into the irrigation water and delivering it directly to the roots through a drip irrigation system.

(2b)

Alley farming is a type of agroforestry system in which crops are grown in the alleys between rows of trees to provide multiple benefits, such as improving soil fertility, providing shade and wind protection for crops, and improving the microclimate for plant growth.

While Ley farming, also known as ley grazing or pasture cropping, is a type of farming system that involves planting crops in pastures or fields that are used for grazing livestock.

Given:

Land Area = 4.9 hectares 

= 49000m² 

 Area of spacing = (7×7)m² 

= 49m² 

Total number of seedlings transplanted = (49000)/49

= 1000seedlings

(3cii)

Rate of fertilizer applied = 350kg/ha

Total quality of fertilizer applied = (350×4.9)ha 

= 1,715kg
