Being the rainfed crops of drylands, the yields of pulses are low and fluctuate from year to year. Gram and tur are the main pulses cultivated in India. Gram is cultivated in subtropical areas.
Pulses are typically rainfed crops that rely on natural precipitation for their water requirements.
As a result, their yields can be highly dependent on the availability and distribution of rainfall, which can fluctuate from year to year.
The lack of irrigation and the reliance on rain make pulse crops vulnerable to variations in weather conditions, leading to lower and fluctuating yields.
