Abstract

Influence of spacing and nutrition on the incidence of cotton diseases was assessed. The plants raised with the wider spacings of 90 X 30 cm were found to record significantly less incidence of Alternaria leaf spot. grey mildew and boll rot diseases than the plants taised with closer spacings of 60 X 30 and 75 x 30 cm. There was linear increase in Alternaria leaf spot incidence with increase in N levels and decrease in K levels but there wes not much variation on the incidence of grey mildew and boil rot due to N and K levels.
