Study Notes
Introduction to Weeders
- Weeds are plants that grow in areas where they are not desired by farmers, limiting or disrupting crop growth and production.
- Weeds are characterized by their ability to rapidly populate large areas through reproduction and dispersal.
Importance of Weed Control
- Weed control is crucial to prevent massive economic loss in farmland productivity.
- If left unmanaged, hardy and invasive weeds can lead to huge economic loss in the long run.
Definition and Objectives of Weeders
- A weeder is a device used to remove unwanted vegetation (weeds) from agricultural lands or gardens.
- The objective of weeders is to remove unwanted vegetation from agricultural fields or gardens.
Classification of Weeders
By Design of Soil Working Part
- Blade type: Rectangular, triangular, or crescent shapes with cutting edges sharpened and hardened.
- Tine type: Straight, curved, round, or square cross-section steel rods with sharply pointed and hardened soil engaging ends.
- Rotary type: Curved or straight spikes or puddles radially attached to a common axle, rotating to uproot and bury weeds.
By Power Source
- Manually-operated weeders:
- Hand-held weeder: Utilizes blade or tine type soil working parts with short, medium, or long handles.
- Push-type weeder: Utilizes blade, tine, or rotary soil working parts for dry and wet field weeding.
- Animal-drawn weeder: Pulls soil working parts mounted on a frame or tool bar for dry field weeding.
- Power-weeder: A rotary weeder driven by its own engine for wet field weeding.
- Tractor-mounted weeder: Soil working parts mounted on a frame or tool bar and pulled by a two- or four-wheel tractor for dry field weeding.
Operator and Equipment Requirements
- The operator should be in good health, experienced in using the weeder, and familiar with the operation and requirements of the test method.
- The operator's height, weight, and stature should be recorded.
- Pulse rate and blood pressure before and after each test trial should be recorded.
- The draft animal should be in good physical condition during the test.
- The draft of the weeder should not be more than 15% of the animal's body weight.
- The tractor should be compatible with the weeder according to the manufacturer's specifications.
