Response of Maize and Wheat to Potassium Application in Soils Differing in Available Potassium Status

Experiments were conducted on cultivators' fields to study the response of maize and wheat to applied potassium on soils differing in available potassium. Maize responded up to 90 kg K₂O/ha in low and medium K soils and to a dose of 60 kg K₂O/ha in soils high in K status. Response of wheat was observed to a level of 90 kg K₂O/ha on soils low in potassium and up to 60 kg K₂O/ha on medium and high K soils.
