Abstract

High nitrogen application increased corn borer, earworm and katydid incidence in sweet sorghum yield consequently increasing the occurrence of spiders.The addition of VAM resulted in more corn silk beetle and further increased actual counts of corn borer.However, it decreased corn borer damage on the stalk in terms of borer holes and tunnel length, increased stripped stalked yield and sugar content of the juice. Further, at half rates of fertilization, the application of VAM produced stripped stalk, juice yield and sugar content that are equal to that of full fertilization. Planting at 100 cm furrow distance resulted in reduced insect pest infestation and increased stripped stalk and juice yield.
