How solar irrigation in Bihar has helped double yield
At a time when farmers across the country are in distress, solar power-irrigated agricultural fields at Chakhaji village in Pusa block, Samastipur, Bihar, are lush green. Standing resplendently are bumper crops of peas, tomatoes, a variety of vegetables and tobacco.
Since the solar power irrigation project was launched towards the end of 2016, dividends have been good. There is no more dependency on the polluting diesel pump sets or the vagaries of State electricity to pump water into the fields. Solar panels herald improved irrigation, carbon-free air and increased earnings for farmers.
