Answer 2

Answer:

• Pulses need less moisture and survive even in dry conditions. Being leguminous crops, all these crops except arhar help in restoring soil fertility by fixing nitrogen from the air. Therefore, these are mostly grown in rotation with other crops.
• Maize is a crop which is used both as food and fodder. It is a kharif crop which requires temperature between 21oC−27oC and grows well in old alluvial soil. In some states like Bihar maize is grown in rabi season also.
