Total uptake of P, S, Ca and Mg were increased due to application of lime which was mainly associated with increased wheat yields. The findings showed that liming is beneficial for wheat cultivation in the Ranishankail soil series of Dinajpur. The application of 2.0 t lime ha-1 appears to be optimum for desired soil pH for wheat (>pH 6.0), increased availability of nutrients and ultimately increased wheat yield. }, number = {11}, doi = {10.12944/CWE.4.1.06} }
