  2. They are require lots of water for irrigation

  3. They have a low productivity.

  4. Both A and B
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Although the high yielding variety of seeds gave a huge amount of production, it has some disadvantages also. They require a lot of water in the field which leads to the decreasing water table. Also, the HYV seeds required higher production cost in terms of irrigation equipment. It also has an adverse effect on the environment, as HVY seeds require more fertilizer to be added to the soil for better production, which decreases the fertility of the soil.

After red gram, maize and corn are cultivated because _________________.

  1. They increase fertility of soil
  2. They fix $N _2$ in soil

  3. They enhance growth of plant

  4. They prevent disease caused by spotted bollworm
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Total dry matter and yield of maize, corn and red gram planted in soil have shown an increase in the soil fertility. Maize and corn not known to fix atmospheric nitrogen. Spotted bollworm affect the cotton plants and the gram, maize and cotton do not affect the pathogenesis. 


So, the correct answer is, 'They increase the fertility of soil'.
