Nutrient use efficiency in terms of yield and uptake as influenced by multinutrient briquettes in bt-cotton grown on vertisol
The field experiments were conducted during 2015-16 and 2016-17, at research farm of Vasantrao Naik Marathwada Krishi Vidyapeeth, Parbhani during kharif to study the Economics of Bt-cotton as influenced by application of multinutrient briquettes (NPKZn) through soil with drip irrigation. The experiment was laid out in a Randomized Block Design with five treatments [(T1: Absolute Control (No fertilizer application), T2: Soil application of 120:60:60 by N, P2O5, K2O kg ha-1 and Drip irrigation, T3: RDF through fertigation (soluble fertilizer: 80:40:40 NPK kg ha-1), T4: 120: 60: 60 kg NPK ha-1 through briquettes with drip irrigation, T5: Application of NPK+ micronutrient briquettes (120:60: 60 NPK kg ha-1 +20 kg ha-1 ZnSO4)] with four replications. The results of the investigation indicated that the application of NPKZn briquettes coupled with drip irrigation found to be effective in increasing the seed cotton yield. The uptake of nutrient was increased with advancement of crop growth. The maximum macro and micro nutrient use efficiency (i.e. NPK and Zn) obtained in NPKZn briquettes coupled with drip irrigation while minimum in absolute control was due to low yields.
