Field experiment was conducted at Agricultural Research Station, Borwat Farm, Banswara during Kharif-2012 to find out the optimum plant geometry and fertility levels for inter specific cotton hybrids. Sowing of RAHB-189 cotton hybrid gave significantly higher seed cotton yield (1798 kg ha-1) over DCH-32. The maximum seed cotton yield (1976 kg ha-1) was observed under plant geometry of 90 x 60 cm than closer plant geometry of 90 x 45 cm and wider plant spacing 90 x 90 cm. Though, yield attributing parameters such as bolls plant-1 and boll weight were statically improved in wider as compared to closer spacing it could be increase the seed cotton yield under sowing at 90 x 60 cm plant spacing. Among fertility levels, similar seed cotton yield was recorded with the application of 100 % RDF (1983 kg ha-1) and 125 % RDF (2018 kg ha-1) but both were significantly better than that of 75 % RDF and plant geometry 90 x 60 cm seemed to be ideal for inter specific hybrid cotton for realizing higher productivity under the specific agro climatic zone IV b.Keywords
