Pulses are the main source of protein for vegetarians. Tuver, mung, gram, peas, beans, math, udad etc. are classified as pulses. Tuver, udad, mung, math are Kharif crops whereas gram, peas and lentil (masur) are Rabi crops. All Indian states grow pulses except those which experience heavy rainfall. Madhya Pradesh, Rajasthan, Uttar Pradesh, Maharashtra, Odisha, Bihar, Andhra Pradesh, etc. are major states producing pulses. In Gujarat tuver is grown more in Vadodara district, mung and math in Kachchh district and udad in Patan district. By growing pulses the nitrogen level of soil lost due to other crops increases. As a result, pulses are grown as inter-crop along with or after the main food crops.
