Effect of fertilizer application on growth, hebage and oil yield in hybrid aromatic tulsi

A field experiment was conducted for an inter-specific hybrid ( Ocimum kilimandscharicum and Ocimum basilicum) variety CIM-Shishir of Ocimum at College of Forestry, Dr Balasaheb Sawant Konkan Krishi Vidyapeeth, Dapoli during 2021-2022 to analyse the response fertilizer application on growth, fresh biomass, oil content and oil yield. Experiment was laid out in randomized block design (RBD) with six treatments (with four replications): T₁ (control-no fertilizer), T₂ (FYM 10 T ha^-1), T₃ (FYM 10 T ha^-1) +100% NPK, T₄ (FYM 10 T ha^-1) + 75% NPK, T₅ (FYM 10 T ha^-1) +50% NPK, T₆ (RDF @ 160:80:80 NPK. Plant height (110.80 cm), number of primary branches (8.05), fresh biomass yield (537.75 quintal ha^-1), oil content in fresh herb (0.70 %) and oil yield (221.25 kg ha^-1) was highest in response toFYM (10T ha^-1) + 100% NPK application and lowest was in control (no fertilizer application). From these results it was concluded that dose of fertilizer FYM (10 T ha^-1) + 100% NPK (160:80:80 kg ha^-1) increase the growth, fresh biomass yield, oil content and oil yield in hybrid aromatic tulsi.
