Abro, F.A.
Studies were carried out under field conditions on the effect of NPK fertilizers on damage compensation and nutritional status in cotton. Cotton variety (CRIS-134) was sown in a Randomized Complete Block Design with three replications on May 22, 2005. The pest damage was simulated by artificially removing the leaves and fruiting bodies of cotton plant. The leaves and fruiting bodies removal ranged between 15 to 75 %. Nitrogen, Phosphorus and Potassium fertilizers were applied two times that is, 64 and 88 days after sowing. Two controls were maintained one in which leaves and fruiting bodies were not removed and NPK fertilizers were also not applied and another in which leaves and fruiting bodies were not removed but NPK fertilizers were applied. It was concluded that there was no significant effect of either application of NPK fertilizers or removal of leaves and fruiting bodies on pest infestation and yield attributes of cotton in present stu dy.
