A field experiments were carried out during 2012–13 and 2013–14 at Tamil Nadu Agricultural University, Coimbatore to study the root characters and yield of Bt cotton as influenced by crop geometry and drip fertigation. The experiment was laid out in a strip plot design with three replications. The treatments in main plot consisted of four crop geometry levels (120 x 60 cm, 120 x 90 cm, 150 x 60 cm and 150 x 90 cm) and sub plots consisted of four nutrient levels viz., 75%, 100%, 125% of recommended dose as water soluble fertilizer (WSF) through drip system and as conventional practice. Here, 75% of the P as basal (single super phosphate) and remaining 25% P as Water soluble fertilizer and entire quantity of N and K as water soluble fertilizer was applied based on recommended fertigation schedule. The experimental results revealed that combination of 125% water soluble fertilizer and 150 x 90 cm crop geometry recorded higher root characters and 120 x 90 cm recorded higher seed cotton yield.
