Abstract
Use of pesticides to eradicate pest attack on cotton crops has increased substantially during the past decade posing a serious threat to environment and human health. Application of nitrogenous fertilizers which modulates plant metabolism might reduce pest and pest-induced viral diseases. Understanding physiological basis of nitrogen nutrition on disease incidence in cotton may help in developing strategies to prevent, avoid, escape and control viral diseases. Thus, responses of two cultivars of cotton (Gossypium hirsutum L.), S-12 (CLCuV-susceptible) and CIM-448 (CLCuV-resistant), to varying concentrations of nitrogen were examined. Plants of both cotton cultivars were grown at varying concentration [224
