Field experiment was conducted to study the influence of plant spacings on the seed cotton yield and yield components in cotton during winter 2016–2017 at Tamil Nadu Agricultural University, Coimbatore, Tamil Nadu, India. The experiment was laid out in a split-plot design and replicated thrice with two cotton genotypes Co 14 and TCH 1819 and seven spacings 90 cm x 45 cm, 60 cm x 30 cm, 90 cm x 45-10 cm, 60 cm x 30-10 cm, 80 cm x 10 cm, 90 cm x 10 cm and 100 cm x 10 cm. Observations on yield attributes and seed cotton yield were recorded. Yield components including number of sympodial branches/plant (14), number of flowers/plant (20), number of bolls/plant (13), single boll weight (3.13 g) and seed cotton yield (2734 kg/ha) were higher in the Co 14 variety when compared to TCH 1819. In the present study, Co 14 with 80 cm x 10 cm spacing gave high seed cotton yield.
