A field investigation was carried out at Tamil Nadu Agricultural University, Coimbatore during winter season of 2017 - 2018 to determine the effect of row spacing on growth and yield of cotton genotype TCH 1819. The experiment was laid out in Randomized Block Design (RBD) with seven spacing treatments viz., 60 x 15 cm, 60 x 20 cm, 75 x 15 cm, 75 x 20 cm, 75 x 30 cm, 90 x 15 cm, 90 x 20 cm and was replicated thrice. Significant variation for plant geometry was observed for all the traits studied. The plant geometry of 60 x 15 cm recorded significantly higher plant height, Leaf Area Index (LAI), Dry Matter Production (DMP). The number of sympodial branches per plant and number of bolls per plant were found significant in wider spacing of 75 x 30 cm. The narrow spacing of 60 x 15 cm registered highest seed cotton yield, net return and B: C ratio followed by the spacing of 75 x 15 cm due to more plant density per unit area.
