- Future increment of even aged crop can be from valid yield table
- Under stocked stands tend to approach fully stocked stands with increase in age, though more rapid growth than the latter
- Both (a) & (b)
- None of these
- Current annual increment (CAI)
- Mean annual increment (MAI)
- Both (a) & (b)
- None of these
- Every year, the volume of a growing tree or of a stand of trees, increases by quantity
- But periodic annual increment after 5/10 years is taken to be CAI
- Both (a) & (b)
- None of these
- In case of bela forest, after feeling the shisham, trenches are made
- In other countries root suckers are produced differently i.e. They expose the roots of the stump and mark very small injuries on the roots on equal distance
- Both (a) & (b)
- None of these
- Without any injury e.g. Populus alba and Populus eupharatica
- When they are felled e.g. Prosopis cineraria
- Both (a) & (b)
- None of these
- Axe
- Saw
- Both (a) & (b)
- None of these
- Those which produce more and vigorous root suckers
- those which produce root suckers less in number
- Both (a) & (b)
- None of these
- If very tall stump, will be left it will give more coppicing shoots due to its thickness of bark
- When stump are of average height, they will produce coppicing shoots easily e.g. In Olea cuspidata
- Both (a) & (b)
- None of these
- The species (Shisham and Acacia niloticproduce good and vigorous coppice shoots
- The species (Quercus incana) produce coppices hoots also but they are few and weak
- Both (a) & (b)
- None of these
- New
- Young
- Both (a) & (b)
- None of these
- Seed
- Vegetative
- Both (a) & (b)
- None of these

- To closeness of crowns boles and roots
- Both (a) & (b)
- None of these
