What is weeding in Class 8th?

In Class 8 Science, weeding is defined as the process of removing unwanted plants (weeds) from crop fields to ensure proper crop growth and better yield.

The NCERT Class 8 Science textbook explains weeding in the chapter Crop Production and Management. Weeds are harmful because they take away essential nutrients and water from the soil, which should go to the main crop. They also block sunlight and slow down the growth of the crops. Students learn that if weeds are not removed, crops may become weak, production will reduce, and the harvest will not be profitable.

Points highlighted in Class 8 syllabus

• Weeds compete with crops for light, space, water, and nutrients.
• Weeding is carried out before the crops flower or produce seeds.
• Weeds spread quickly and can damage the entire field if ignored.

Methods of weeding taught in Class 8

Students are introduced to manual methods (like khurpi and hand pulling), mechanical methods (like weeders), and chemical methods (using weedicides). Safety while using chemicals is also stressed in the book.

Thus, in Class 8th, weeding is taught as an important agricultural practice. Understanding this topic builds a foundation for higher classes, where students study farming practices in greater detail.
