According to the FAO of the united nations,India is the number one producer and consumer of the pulses in the world and amounts to about 25 percents of the worlds production.But still the price of pulses keeps crashing which severely affects the farmer and the farming industry.Reasons behind these can be enumerated as a domestic average production of india about 22 MMT while consumption was about 29MMT from 2011-12 to 2016-17,so we have to import about 6MMT of pulses from outside b the price of the imported pulses being lesser than the MSP provided to the farmers result in the prices being vary c there has been trends of people shifting from vegetables to dairy and meat products for their daily protein requirement
