The incidence of whitefly, Bemisia tabaci on different plant spacing’s i.e. 67.5 cm ×105 cm, 67.5 cm × 90 cm, 67.5 cm × 67.5 cm, 67.5 cm × 45 cm and 67.5 cm × 30 cm was studied. The maximum populations of whitefly, Bemisia tabaci was noticed in the plant spacing of 67.5 cm × 30 cm followed by 67.5 cm × 45 cm. Whereas, minimum population was noticed in plant spacing 67.5 cm × 105 cm followed by 67.5 cm × 90 cm. The maximum seed cotton yield was reported from the plots having spacing of 67.5 cm × 67.5 cm.
