Abstract: To study the effect of land configurations and spot application of organic manures on yield of Bt cotton under Alfisols of Northern Karnataka was conducted during kharif season 2018–2019. The experiment was at College of Agriculture, Hanumanamatti, Karnataka and it was laid out in split plot design with three replications. The experiment consist of two main plot treatments viz., M1: ridge and furrow method of sowing and M2: flat bed method of sowing and six sub plot treatments viz., S1: RDF-Control, S2: RPP-Package of practice, S3:S1 + Blanket application FYM @ 5 t ha-1, S4:S1 + Spot application FYM @ 5 t ha-1, S5: S1 + Blanket application vermicompost @ 2.5 t ha-1, S6: S1 + Spot application vermicompost @ 2.5 t ha-1. The two year mean data revealed that plants grown under ridge and furrow method (M1) of sowing had significantly higher growth and growth attributes, yield and yield attributes. With respect to Sub-plot treatment, (S6) RDF+ spot application vermicompost @ 2.5 t ha-1 recorded significantly higher growth and growth attributes, yield and yield attributes. Among different treatment combination, the M1×S6: plots supplied with RDF+ Spot application of vermicompost @ 2.5 t ha-1 (S6) under ridge and furrow method of sowing (M1) found to be effective over other treatments.
