Explanation:

Both 1 and 2

Pulse is a rainfed crop: Yes, pulses are often rainfed crops, meaning they rely on rainfall for their water requirements. They are typically grown in regions where irrigation facilities may be limited.

Pulses increase the fertility of land by nitrogen fixation: Yes, this statement is also correct. Pulses belong to the legume family, and many legumes have the ability to form a symbiotic relationship with nitrogen-fixing bacteria in their root nodules. This process helps in converting atmospheric nitrogen into a form that plants can use, thereby increasing the nitrogen content in the soil and contributing to soil fertility.
