25.                      
    1.                
       • Nitrogen fixing ability – The trees should be preferably legumes. They should be capable of fixing Nitrogen into the soil for use by other crops;
       • Fast growing ability – trees chosen should be fast growing and early maturing so that they can be put into other uses – thus should have a high biomass production e.g fuel wood
       • Multipurpose nature – the chosen trees should be able to meet other uses such as provision of fuel woods, fodder, poles and timber.
       • By – product production – The best agroforestry tree species should be able to produce economic products and by-products which can be used or sold for income e.g those producing edible leaves, fruits, medicinal products, poles and fodder.
       • Deep rooted with a narrow root zone – when agro-forestry trees have deep roots, they acquire their nutrients from lower soil horizons where most plant roots do not reach-hence minimal competition for nutrients;
       • Non-competitive ability with main crop- a good agroforestry tree species should not compete with the main crops for light and nutrients unnecessarily.
       • Nutritious and palatable – trees used for this purpose should be both nutritious and palatable as leaf fodder for livestock use.
       • Easily coppiced – the trees species which will be able to regenerate after cutting back for pruning are preferred. (5 x 2 = 10mks)
         (Characteristic – 1mk, explaination – 1mk)
    2.                      
       • Use of lethal temperature – These are too hot or too cold conditions which kill pests;
       • Proper drying of produce – drying of grains makes them too hard for pests to penetrate;
       • Flooding – drowns underground pests eg moles and cutworms;
       • Suffocation – pumping carbon(IV) oxide into hermetic Cyprus bins deprives pests of oxygen;
       • Physical destruction – done through trapping, hand picking and killing them.
       • Use of scare crows/ devices – for scaring large animals and birds from crop fields;
       • Use of physical barriers – Barriers such as trenches fences, rat quards prevent pests from getting into crop fields or stores.
       • Use of electromagnetic radiation – electromagnetic radiations are used to kill insect pests through deactivation of enzymes (5 x 2 = 10mks)
         (Method – 1mk, Explanation – 1mk)
