Nearly 700 years ago, Muhammad bin Tughlaq, who ruled Delhi, started the ministry of agriculture and wanted all the fallow land to be brought under cultivation. Tughlaq wanted cultivation of high-value crops and decreed: “Wherever wheat is grown, barley should be grown, wherever barley is grown, sugarcane should be grown and wherever sugarcane is grown, dates and grapes should be grown.” He failed, destroying family farms for generations. Still at it, we call it diversification of agriculture.
