Operations carried out for the benefits of forest crop at any stage of its life. It essentially covers operation on the crop itself and competing for vegetation and include weeding, cleaning, thinning, felling, pruning, climber cutting, girdling but exclude soil working, drainage, irrigation, and burning, etc.
NEED FOR TENDING OPERATIONS:
Two major needs:
2. To provide growing space for trees.
- The act of reducing the chanced of insects and other diseases in sanitation. The trees which are susceptible, injured, broken, weak, diseased, or infected by insects are removed.
- Looking for space in which trees extend their masses, lastly tending operations are essential for providing, the tree with more light water nutrients, etc.
- Tending operations result in the achievement of a form which confirms the human sense of liking.
- The removal or cutting back of any sort of weed growth that is interfering with the growth of crop is called weeding.
- Removal means uprooting the entire weed even Morus alba if not required.
- Cutting back is meant by cutting the upper portion but this does not control weeding.
- When plants are 3feet high or less, the stage is seedling. In seedling stage usually, the side branches have yet t come out and light frequently falls upon open interplant spaces and then weeds become active, start competing and start sucking food, hence they are removed.
- Weeds usually come from indigenous spp, some are persistent for example Imperita cylindrical (drub) constantly refuses to leave the land because it is deep-rooted and even plow can hardly do harm to its one feet deep rhizome.
- Weeds mainly appear from seeds, others from coppice and still others form suckers.
- In natural forests, Viburnum spp creates a problem by appearing again and again.
- Weeding should be in early ages because seedlings have to suffer when the weeds surpass them in height.
- For shisham plantation, weeding is done twice in the first year.
- In addition, weeding continues with cleaning as well.
- Tending operations done in sapling crop particularly just before or with the first thinning are involving the removal or cutting back of all inferior growth, climbers, etc” including an excess of coppice shoots and sapling if interfering with better one.
- Sometimes cleaning and the first thing is done simultaneously or sometimes separate.
- Since the sapling branches shade up the ground then weaker type of seedlings may appear, they are undesired and removable.
- Bela plantations of Shisham raised from root suckers and coppices demands cleaning. Here hundreds of coppice shoots are reduced. Here some diseased shisham will also be removed.
- A plant that attaches itself to other plants or objects such as posts and walls as it grows is a Climber.
- This difficulty is faced in nurseries usually seedlings are twined by climbers. Afterward, the internode increases in length. The climber pulls the head of the seedling. Since this host climber can’t be extended, shoot of the seedling is broken.
- Sometimes it completely girdles the shoots and plants die of suffocation. The climber may ravel itself around the crown, so the victim is devoid of light and food.
- Their removal is necessary.
