Agriculture MCQs cover fundamental and applied concepts related to farming, crop production, soil science, irrigation, fertilizers, plant breeding, pests, and agricultural economics. This topic is designed to strengthen conceptual understanding and problem-solving skills through objective questions. It is especially useful for competitive exams such as PPSC, FPSC, KPPSC, BPSC, NTS, OTS, and other testing services, helping candidates prepare with exam-oriented and up-to-date agricultural knowledge.

Low thinning or ordinary thinning is:
A Trees are removed from the lower crown classes
B In the highest grade of low thinnings only the suppressed trees would be removed
C Both (a) & (b)
D None of these
Correct Answer: Both (a) & (b)
Crown thinning or high thinning is:
A Trees are removed from the upper crown classes in order to open up the canopy
B It favour the development of the most promising trees of the same classes
C Both (a) & (b)
D None of these
Correct Answer: Both (a) & (b)
Selection thinning is:
A In principle from the two methods already discussed
B The dominant trees are removed in order to stimulate the growth of the trees of the lower crown classes

D All of the above
Correct Answer: All of the above
The classes of trees are removed in selection thinning:
A They are restricting the development of their neighbours on all sides
B They are less valuable than their neighbours
C They are of no special importance with regard to desirable species mixture
D All of the above
Correct Answer: All of the above
Mechanical thinning is:
A The trees to be cut or retained are chosen on the basis of a predetermined spacing
B Or pattern with little or no regard for their position in the crown canopy
C Both (a) & (b)

B But periodic annual increment after 5/10 years is taken to be CAI
C Both (a) & (b)
D None of these
Correct Answer: Both (a) & (b)
From yield table we determine:
A Future increment of even aged crop can be from valid yield table
B Under stocked stands tend to approach fully stocked stands with increase in age, though more rapid growth than the latter
C Both (a) & (b)
D None of these
Correct Answer: Both (a) & (b)
