Context

In a major boost to the scientific efforts for crop improvement to save nitrogenous pollution and fertilizers worth billions, Indian biotechnologists identified candidate genes for nitrogen use efficiency (NUE) in rice. 

Prelims question:

Recently, Indian scientists have identified genes to improve fertilizer nitrogen use efficiency (NUE) in rice. What are the potential benefits in improving NUE of crops?

  1. Improved NUE has the potential to increase yields and profits for the farmers.
  2. It will also reduce water pollution and algal blooms.
  3. It decreases the emission of agricultural nitrous oxide to the Indian environment which is approx. 300 times more powerful greenhouse gas than carbon dioxide.

Select the correct answer using the codes given below:

  • A.
  • B.
  • C.
  • D.

Mains Question:

The accelerated use of nitrogen is at the center of a complex web of developmental benefits and environmental problems. Substantiate. (250 words)
