Abstract: A Field experiment was conducted during the Kharif 2015 at Agricultural College farm, Raichur to study the effect of high density planting and nutrient management in compact cotton (Gossypium hirsutum L.) genotypes. The result of this experiment revealed that there was no significant difference in growth, yield contributing characters and seed cotton yield in between Rahc-1011 and Rahc-1012 of compact cotton genotypes. Among the genotypes, seed cotton yield of Rahc-1012 (1816 kg ha^-1) was statistically on par with Rahc-1011 (1754 kg ha^-1). Spacing of 60 cm x 30 cm recorded significantly higher (1922 kg ha^-1) seed cotton yield as compared to 60 cm x 45 cm (1566 kg ha^-1) and was on par with 60 cm x 15 cm spacing (1816 kg ha^-1). Application of 125 per cent RDF recorded significantly higher seed cotton yield (2012 kg ha^-1) when compared to 100 per cent RDF (1871 kg ha^-1) and 75 per cent RDF (1473 kg ha^-1).
