Why do we need to control weeds Class 9?

The undesirable plants that grow along with the crops are called weeds. These weeds, feed on the nutrients provided to the crops and thus reduce the supply of nutrients to the crops, thereby, hindering their growth. The growth of these weeds needs to be limited in order to enhance the growth of the plants.

Why the growth of weeds is harmful?

They compete with crop plants for water, nutrients, space and light. They affect plant growth. Presence of weeds increases the cost of agriculture and hinders the progress of work.

Why is it necessary to control weeds while growing field crops?

Weeds reduce crop yields by competing for water, nutrients and light. Some weeds release toxins that inhibit crop growth, and others may harbor insects, diseases or nematodes that attack crops.

What are weeds give two examples of weeds need to control them and methods to control them?

Ex- Clover and Dandlion. Two effective methods to control weeding are Mulching and Pulling. In mulching, the weeds are covered with black plastics or damp newspapers or anything to prevent it from receiving sunlight and cease their growth.

What is protecting from weeds?

Ans: We can protect the crops from weeds by using different methods, including hand cultivation with hoes, powered cultivation with cultivators, smothering with mulch, lethal wilting with high heat, burning, and chemical control with weedicides or herbicides (weed killers).

What is weeds Class 8 Short answer?

The unwanted plants which grow along with a cultivated crop are called weed. The type of weed vary from field to field,crop to crop,season to season. For Ex:Wild oat,grass, Amaranthus, chenopodium etc. The process of removing weeds from a crop field is called weeding.

What is the beneficial and harmful effect of weeds?

Harmful and Beneficial effects of Weeds. Weeds have serious impacts on agricultural production. Weeds compete with crops for water soil, nutrients, light, and space, and thus reduce the crop yields. An estimate shows that weeds can deprive the crops 47\% N, 42\% P, 50\% K, 39\% Ca and 24\% Mg of their nutrient uptake.

What are the important of weeds?

Weeds are responsible for significant crop yield losses and financial losses in agricultural production in the order of 10\% per year worldwide [1]. Weeds compete with other plants for limited resources (mainly nutrients, water and light), and competition can be successful through the use of certain strategies.

What are weeds need to control them?

Need for control Weeds compete with productive crops or pasture, they can be poisonous, distasteful, produce burrs, thorns or otherwise interfere with the use and management of desirable plants by contaminating harvests or interfering with livestock.

What are weeds need to control them and method to control them?

Tilling before sowing of crops helps in the uprooting and killing of weeds. Which may dry up and get mixed with soil. Weeds are also controlled by using certain chemicals, called weedicides. Weedicides are sprayed in the fields to kill the weeds.

What is the importance of weeding?

Weeding can be defined as the removal of weeds (unwanted plants) from the field. Weeding is necessary because weeds compete with main crop plant for the different factors such as water, sunlight, nutrients and space and hence affect plant growth. Due to unwanted plants, there is reduction in yield also.

Why do weeds grow so fast?

Weeds grow fast and fight them for resources. Generally, they’re pretty good at this, which will weaken – and can even kill – your precious plants. And the more they grow, the harder they are to destroy at the root. Tackling them early will solve you a headache in the long run.

How can we control weeds in crops?

Tilling before sowing of crops also helps in removing weeds: Tilling uproots the weeds. The best time for the removal of weeds is before they produce flowers and seeds.

Why do herbicides kill weeds so quickly?

The weeds’ growth happens quicker than the plant can handle and dies. Other selective herbicides target photosynthesis; the process in which plants produce energy/food from the sunlight it receives.

Why are weeds bad for the garden?

Weeds may be unwanted for a number of reasons: they might be unsightly, or crowd out or restrict light to more desirable plants, or use limited nutrients from the soil. They can be home to, and spread, pests and diseases that can degrade the quality of crop or horticultural plants.
