Abstract: An experiment was conducted at Cotton Research Station, Nanded during three cropping seasons (2012-15) to evaluate effect of one plant hill^-1 under different plant geometries in comparison with two plants hill^-1 under rainfed condition. The treatments were factorial combinations of three plant geometries (90 x 60 cm, 120 x 45 cm and 150 x 30 cm) and number of plants hill^-1 (one and two plants hill^-1). There was 12.08 per cent increase in seed cotton yield when Bt cotton was planted in 120 x 45 cm geometry over that of 150 x 30 cm. Similarly increase in bolls plant^-1, boll weight, yield plant^-1 and monetary returns were also received from 120 x 45 cm geometry over wider. The one and two plants per hill^-1 had non-significant results for seed cotton yield, yield attributes although number of branches were more in two plants hill^-1. The Moisture content in soil at 60 DAS and ginning out turn were not affected significantly due to plant geometries and number of plants hill^-1.
