Abstract: A field investigation entitled "Standardization of agro-techniques for cotton under high density planting system for southern dry zone of Karnataka'" was conducted at Krishi Vigyan Kendra, Chamarajanagar during kharif season of 2016 in medium black cotton soil. The experiment was laid out in split plot design consisting of five levels of planting geometries viz. 45 X 10 cm, 45 X 20 cm, 60 X 10 cm, 60 X 20 cm and 90 X 60 cm as main plot treatments and three cotton genotypes viz., DSC-99, ARBC-64 and SURAJ in sub plot and replicated thrice. The results revealed that there is a significant difference were observed for planting geometries and varieties. The variety DSC-99 recorded significantly higher yield seed cotton yield (1383 kg/ha) followed by ARBC-64 (1383 kg/ha). DSC -99 performed better with respect to yield attributes viz, number of bolls (14.68/plant), boll weight (3.21g/plant) and seed cotton yield (43.53 g/plant). Among the planting geometries spacing at 45 X 10 cm recorded significantly higher Seed cotton yield (1589 kg/ha), Gross returns (Rs. 82,623/ha), Net returns (Rs. 37071/ha) and B:C ratio (1:81). However the interaction effects did not differ significantly for all the parameters studied.
