Abstract: Field experiment on Bt cotton by conjoint use of organic and inorganic fertilizers based on targeted yield approach on vertisols was conducted with Bt cotton (NCS-207, Mallica) in Rahuri during 2007-08. Fertilizer adjustment equations were formulated under (STCRC) system for Bt cotton following Ramamurthy’s inductive-cum-targeted yield model. The nutrient requirement for production of one quintal of Bt cotton was found to be 5.84, 2.02 and 3.51 kg of N, P2O5 and K2O, respectively. The per cent contribution soil and fertilizer nutrients were found to be 45.87 and 37.77 for N, 83.63 and 31.90 for P2O5 and 17.68 and 27.99 for K2O, respectively. Likewise, the per cent contribution from farmyard manure (FYM) was 11.74, 14.54 and 14.57 kg ha-1 of N, P2O5 and K2O, respectively.
