| # | Question | Ans |
|---|---|---|
| 1. |
The process of grafting in crop production involves A. The fusion of gametes of two crops B. Inducing rooting from stems C. The transfer of a bud from one crop to another D. The joining of two parts from related crops. |
D |
| 2. |
If the recommended spacing for a tree crop is 2.5cm by 4.0m determine the number of seedlings required to plant a 2-hectare farmland. A. 1,000 B. 2,000 C. 10,000 D. 20,000 Detailed SolutionNo of seedling= (Area of land)/(Area of crop) = (2 ×10,000)/(2.5 ×4) = 2,000 seedlings |
|
| 3. |
A regulatory control of diseases in crop production is A. roughing B. quarantine C. crop rotation D. Soil tillage. Detailed SolutionOption B is correct as Quarantine involves isolation to prevent control disease. |
|
| 4. |
Which of the following statements about soil organisms is false? A. Soil pH will affect the population of soil organisms B. Population of soil living organisms is increased with increase in soil organic matter C. Soil with good texture and structure cannot harbour soil microbes D. Soil temperature affects the activities of soil organisms. |
A |
| 5. |
The data for feed consumption and weighing gain of four farm animals labelled P, Q, R and S are shown below. A. P B. Q C. R D. S Detailed SolutionFCR for P = 20/50=2/5=0.4FCR for Q = 30/90=1/3=0.33 FCR for R = 25/100=1/4- 0.25 FCR for S = 30/150=1/5=0.2 Option A is correct because P has the highest FCR |
|
| 6. |
In preparing for parturition of a sow, warmth should be provided to A. Promote growth of hair of the young B. make the young suckle colostrum's C. prevent anaemia in the young D. prevent chilling of the young. Detailed SolutionOption D is correct as the young need warmth to avoid cold. |
|
| 7. |
In which layer of the soil profile do most biological activities occur? A. D-horizon B. C-horizon C. B-horizon D. A-horizon Detailed SolutionOption D is correct as this A-horizon contains most minerals and organic matter. |
|
| 8. |
Which of the following statements about agricultural development are true? It leads to A. I, II and III only B. I, II and IV only C. I, III and IV only D. II, II and IV only Detailed SolutionOption A is correct because agricultural development entails employing diverse means, through mechanization and new innovations and also government policies to boost agricultural production. |
|
| 9. |
Under the communal land tenure system, farmers find it difficult to secure loans because A. land holdings are small and fragmented B. they are poor C. land holdings cannot be used as security D. they are mostly illiterate. Detailed SolutionOption C is correct because in communal land system, land is owned/ allocated to a community and not individual. |
|
| 10. |
Pineapple is widely propagated using A. seeds B. suckets C. Slips D. cuttings Detailed SolutionOption B is correct because the sucker is the reproductive part of a pineapple. |
