Abstract:
Effect of plant spacing on incidence of whitefly, Bemisia tabaci on Bt cotton was studied at Research Farm, College of Agriculture, SKRAU, Bikaner during Kharif, 2018. The incidence of whitefly, B. tabaci on different plant spacing 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, B. 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.
