Abstract
The effect of NPK fertiliser combinations on the development of eyespot was studied both in the greenhouse and in the field. Low levels of nitrogen fertilisers (urea) were found to reduce the severity of eyespot on wheat in comparison to controls without fertilisers. The severity of eyespot, however, increased as the dosage of nitogen fertiliser was increased above 60 kg/ha. Combinations of urea and phosphorus increased severity of eyespot while combinations with potassium reduced severity. A “recommendation” was made for such application: 90 kgN/ha or 90 kgN: 30 kgP/ha: 30 kgK/ha.
