Answer 2

Hey mate!

Here is your answer

HOTS Question:

1. (d) using better varieties of crop plants. Better varieties of crop plants will result in increased production as they give higher yield as well as high resistance to diseases.

2. The drawbacks of uneven distribution of seeds in a field, while sowing, are:

(i) They will compete for water, nutrients and sunlight that result limited growth. (ii) If they are sown far apart, it will result in the wastage of field area. (iii) If seeds are not sown at the proper depth and covered by soil, they may be eaten up by birds.

3. We won't find fully­ grown crop plants in a nursery like rice, tomato, onion, etc because they are transferred to the fields from nurseries in their seedling stage.

4. No, farmers adopt crop rotation to maintain the fertility of the soil. For examples , wheat and rice use large amount of nitrogen from soil therefore legumes plants are grown next to the wheat or rice to replenish nitrogen naturally in field.
