Abstract:
The field experiment was laid out in Factorial Randomized Block Design during rabi season of 2017-18 at Research Farm of the Department of Agronomy, College of Agriculture, Dapoli, Dist. Ratnagiri Maharashtra. The four levels of N and P application viz. F₁- RDF (150:50:50 Kg NPK ha^-1), F₂-75% RDN + Full dose of P & K + N-Fixer (Azotobacter chroococcum), F₃-75% RDP + Full dose of N & K +P-Solublizer (Aspergillus niger) and F₄-75% RDN+ 75% RDP+ Full dose of K+ N-Fixer + P-Solubilizer were added as a factor-1 and four foliar applications of micronutrients as a factor-2 replicated thrice. Foliar application of micronutrients S₁- Control (Water Spray), S₂- Foliar spray of Zinc (ZnSO₄@0.5%) and S₃- Foliar spray of Boron (Borax @0.2%) and S₄- Foliar spray of Zinc and Boron (ZnSO₄@0.5%) + (Borax @0.2%)Soil application of fertilizers and bio fertilizers with foliar spray of zinc and boron was showed significant result with respect to yield. The treatment receiving F₄S₄ (75% RDN+ 75% RDP+ Full dose of K+ N-Fixer + P-Solubilizer and foliar spray of ZnSO₄@ 0.5% + Borax @0.2%) showed highest yield (27.21 t ha^-1) which was found significantly superior over rest of the treatments except F₄S₃ treatment combination. Interaction effect of application of fertilizers along with biofertilizers and foliar spray of micronutrients found highest anthocyanin content (14.83 mg 100g^-1) and total phenol content (24.95 mg 100g^-1) of brinjal fruit significantly increased due to application of 75% RDN + Full dose of P & K + N-Fixer and foliar spray of Zinc and Boron.
