1.  Tending of forest crops includes:
A. Cultural operation are the operations undertaken for the completion B. Or assistance of regeneration/afforestation
C. Both (a) & (b) D. None of these

2.  Beating up (Replacement) covers:
A. Hundred percent successful stocking from the first sowing B. Or planting out is rarely attained except with the more elaborate methods
C. The causalities have to be replaced to give good results D. All of the above

3.  Nurse crop is:
A. Trees are raised with the preliminary object of helping a less hardy species B. They are usually removed at an early stage as soon as they have served this purpose
C. Both (a) & (b) D. None of these

4.  Cover crops is:
A. Crops of subsidiary species, (usually low shrubs but on occasion small trees or even herbs) B. Intentionally introduced into a plantation with the primary object of restoring a cover to the soil as quickly as possible
C. It minimizing the known deterioration consequent on exposure D. All of the above

5.  Controlled burning depicts:
A. It is sometimes recommended for plantations as for natural regeneration to put a controlled ground fire through as soon as possible B. As a fire protection measure where the fire risk is great, as often with chir pine
C. Both (a) & (b) D. None of these

6.  Soil working is:
A. Involved in uprooting weeds as compared with cutting them, has been the subject of experiments B. Which indicate that local experience is necessary
C. As sometimes the gain is considerable, whilst at other times, perhaps mainly with light soil and only moderate weeds D. All of the above

7.  The major effects of mulches, irrespective of their composition, are attributed to:
A. Suppression of weeds, by restricting the amount of light on the ground surface and thus hindering their germination and growth B. Conservation of soil, by preventing erosion
C. Maintenance or improvement of soil structure, by eliminating or mitigating the severity of rain and wind action D. All of the above

8.  Thermal insulation, leading to greater deposition of dew. In addition organic mulches also contribute to:
A. Enhanced humification and microbial activity leading to higher nutrient availability B. Improvement of soil structure, by incorporation of plant residues and by encouraging soil fauna.
C. Mulching is of profound importance in dry regions D. Even in more humid climates it may have very beneficial effects with certain species, e.e., the poplar
E. All of the above    

9.  The major types of Mulches is / are:
A. Artificial mulches: Paper and plastic mulches B. Natural mulches
C. Inorganic; soil mulch and stone mulch D. Organic; branches, twigs and leaves, leaf litter, grass weed
E. All of the above    

10.  Tending operations is / are:
A. As operations carried out for the benefit of a forest crop at any stage of its life between the seeding and mature stages B. It essentially covers operations on the crop itself and on the competing vegetation
C. Both (a) & (b) D. None of these
