(c) State two reasons for the inclusion of the plant from which specimen N is obtained in crop rotation. (2 marks)
(d) Mention three uses of specimen P. (3 marks)
(e) State two ways by which the activities of specimen Q affect crops (2 marks)
a) ldentification of specimens N, O, P and Q Specimens
(b) Determination of plant population of specimen
Plant population stand = \(\frac {\text{Area of farmland}} {\text{Feeding area/plant}} \times {\text{plant}}\) =
\(\frac {1 ha}{60cm \times 25cm} \times {1 \text{plant}}\)
OR
\(\frac {10,000m^2} {0.60m \times 0.25m}\) =
\(\frac {10.000m^2} {0.15m^2 } \times {1 \text {plant}}\)
(c) Reasons for the inclusion of the plant from which specimen N is obtained in crop rotation
(d) Uses of specimen P (Guinea corn seed)
(e) Ways by which the activities of specimen Q (Aphids) affect crops;
