Protection from Weeds
In agricultural fields, undesirable plants known as weeds often grow alongside crop plants, competing for essential resources like water, nutrients, and sunlight. The process of removing these weeds is termed weeding, which is crucial for the healthy growth of crops. Weeds can interfere with harvesting and may even be toxic to animals and humans.
Farmers use various strategies for weed control, including tilling before sowing to uproot weeds, ensuring they die and decompose in the soil. The optimal time for weed removal is before the plants flower and produce seeds. Manual weeding involves physically uprooting or cutting the weeds using tools such as a khurpi.
Additionally, chemical methods involve the application of weedicides, like 2,4-D, which are substances specifically designed to kill weeds without harming the crops. These chemicals must be used carefully, as they can pose health risks to people applying them. Proper safety measures should be taken, including covering the nose and mouth when using weedicides. Efficient weed management contributes significantly to crop yields and agricultural productivity.
