An experiment was conducted during kharif season during the year 2016-17 to study the effect of multinutrient briquettes on growth, yield and quality of Bt-cotton grown in vertisol. There was a significant effect of multinutrients briquettes (NPKZn) on plant height, number of leaves, number of bolls per plant, fresh weight gm per plant, seed cotton yield and stalk yield, test weight, lint index, ginning percentage, fiber length and micronair value. The application of NPKZn briquettes @ 120:60:60:20 kg ha^-1 coupled with drip irrigation was recorded higher seed cotton yield, which were at par with application of NPK Briquettes with drip irrigation. The results emerged out clearly indicated that various growth parameters like plant height, number of bolls per plant, fresh weight per plant, seed cotton yield and stalk yield was increased due to application of NPKZn briquettes applied through drip irrigation. It was inferred from the results that application of NPKZn briquettes @ 120:60:60:20 kg ha^-1 coupled with drip irrigation found superior over only NPK Briquettes with drip irrigation and RDF (120:60:60 N and P₂O₅ K₂Okg ha^-1).
