Nutritional status of soils and the incidence of the bunchy top disease of banana (Var Java)- Part VI Effect of application of calcium and magnesium to soil on the ratio of Calcium oxide/Magnesium oxide in the plant and its relation to bunchy top infection

Abstract

Experiments were laid out under semi-field conditions to study the effect of combined application of calcium oxide and magnesium oxide at different concentrations to soil in the ratio of 3:1. The absorption of calcium , magnesium, nitrogen, phosphorus and potassium by plants from soils containing varying quantities of calcium oxide and magnesium oxide was studied. The plants were allowed to be infected by releasing the virus carrying sphids after the initial period of growth, to study whether there was any resistance to the incidence of bunchy top.
