Question

Given below is a conversation between two farmers Heera and Beera.

Heera : Brother Beera, your maize crops look beautiful. They have grown pretty fast.

Beera : Yes, I have sprayed urea this time. What about you?

Heera : Well, I am still relying on good old cow dung. I am saving money for buying a tractor.

Beera : That’s good. Tractor saves a lot of time and labour.

Heera : Yes, it’s been very labour intensive for me and now these weeds have come up.

Beera : Try weedicides, they are very effective.

Now, answer the following questions.

1. List the practices which are not environment friendly and why?
2. What is the advantage of modern agriculture implements over traditional ones?
3. Name one weedicide and the precaution, farmers must take during its application. 

Answer 1

1. The practices used in field that are not environment friendly are use of fertilisers, pesticides, weedicides and other chemical substances that pose health hazards. Tractor though saves labour and time but contribute to air pollution.
2. Modern agricultural implements save both time and labour as compared to traditional equipment. They import more efficiency and accuracy in different agricultural procedures like sowing of seed.
3. The example of weedicide is 2,4-D. The precaution taken by farmers, while spraying it on crops is that they should properly cover their nose and mouth, so as to avoid inhaling these chemicals. Excessive use is harmful, hence they should limit the application of such chemicals.
