Question

Name the technique used for better productivity of crops. Explain why is it necessary to involve this technique to feed increasing population.​

Answer 1

please mark as brainliest

Explanation:

1. Farmers uses HYV ( high yielding variety) seeds.
2. Fertilizer s are also used by farmers .
3. Tissue culture is the technique that is also used to increase production.
4. Multiple cropping and modern technology is also used.

Answer 2

Answer:

Arguments can be made for both pessimism and optimism:

Studies have projected that farmers could achieve far higher yields than they do today. However, methods for estimating these “yield gaps” tend to exaggerate gap sizes and farmers can rarely achieve more than 80 percent of yield potential. The most comprehensive study suggests that fully closing realistic yield gaps is unlikely to be enough to meet all food needs.

The massive yield gains of the 50 years from 1960 to 2010 were achieved in large part by doubling irrigated area and extending the use of scientifically bred seeds and commercial fertilizer to most of the world. Only limited further expansion of these technologies remains possible.

Optimistically, farmers have so far continued to steadily boost yields by farming smarter in a variety of ways, and new technologies are opening up new potential.
