(a)(i) On the graph sheet provided, plot a graph showing the relationship between fertilizer used and tomato yield. Use a scale of 2 cm to 2 units on the x-axis and 2 cm to 2 units on the y-axis.
(ii) Describe the relationship between the fertilizer used and tomato yield.
(iii) Suggest the most appropriate quantity of fertilizer to be applied on the tomato farm.
(b) State three effects of subsidy withdrawal on agricultural production.
(c) List four print media that could be used to disseminate information about a new variety of maize to farmers.
(d) Name two insect pests each of the following crops: (i) maize; (ii) orange.
Answer Details
(a)(i)
(a)(ii) The graph shows a positive correlation between the quantity of fertilizer used and the yield of tomatoes. As the quantity of fertilizer used increases, the yield of tomatoes also increases.
(a)(iii) From the graph, the most appropriate quantity of fertilizer to be applied on the tomato farm would be around 5 bags, as this is the point where the yield of tomatoes is at its maximum.
(b) Three effects of subsidy withdrawal on agricultural production are: reduced farm income, increased input costs, and reduced productivity.
(c) Four print media that could be used to disseminate information about a new variety of maize to farmers are: newspapers, farming magazines, flyers/brochures, and posters.
(d) Two insect pests of maize are: fall armyworm and maize weevil.
Two insect pests of orange are: citrus whitefly and orange fruit borer.
