An experiment was conducted at experimental farm of Department of Soil Science and Agricultural Chemistry, Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani during kharif season, 2015-16. The effect of multinutrient briquettes was studied on growth, yield and yield attributing character of Bt cotton. The experiment was laid out in a Randomized Block Design with five treatments and four replications. The results of the investigation revealed that height of Bt cotton plant at square formation, flowering, boll bursting and harvest was continuously increasing in all the treatments. Maximum increase in height was observed with the treatment receiving RDF through a fertigation in six splits followed by multi nutrient NPK+ Zn briquette application. The maximum number of leaves was observed with treatment RDF through a fertigation at square formation, flowering, boll bursting and at last picking and next best treatment was application of NPK+ Zn through briquette. The highest dry matter was recorded with RDF through a fertigation and NPK + Zn briquette application at last picking and there was almost two fold increase in dry matter from boll formation to last picking whereas the maximum number of bolls was recorded in treatment RDF applied in six splits through soluble fertilizers by fertigation. The application of 80:40:40 kg NPK kg ha-1 through soluble fertilizers by fertigation in six splits have produced more seed cotton yield which was at par with application of 120:60:60 N, P2O5 and K2O through briquettes. Besides, the addition of 20 kg ZnSO4 in NPK briquette proved its superiority over all treatment except fertigation.
