The effect of soil moisture and of N, P and K on incidence of infection of cacao seedlings inoculated with Verticillium dahliae
Incidence of infection of cacao (Theobroma cacao L.) by Verticillium dahliae Kleb. was studied with plant grown in the glasshouse in potted soil or in sand supplemented by nutrient solution. Incidence of infection increased with increase in soil moisture up to 60-70 per cent saturation beyond which it declined but it was not affected by the frequency of watering potted soil in which plants were grown. The levels of N, P and K in sand culture affected their amounts in leaves but did not influence the incidence of infection of cacao by V. dahliae
