BANKURA, 29 NOV: The sale of chemical fertiliser in the black market has had an adverse effect on common farmers in various blocks of Bankura. This has hit potato cultivation, in particular, in the district.
Potato cultivation requires a judicious management of minor irrigation and chemical fertilisers. Nitrogen, phosphate and potassium in the ratio of 10:26:26, besides imported DAP, are the common fertilisers used by potato growers in Onda, Joypur, Kotulpur, Indas, Patrasayer, Simlapal and Bishnupur blocks. The district has set a target of potato cultivation on 32,000 hectares.
