Performance of Valeriana jatamansi in Hill Zone of West Bengal Concerning Manure Sources

The organic source of nutrients would be a promising practice for Valeriana jatamansi cultivation which maintains its curative value. A set experiments was conducted at Hill Zone West Bengal, Kalimpong two consecutive cycles to standardize nutrient management in V. optimum growth and economic yield. Different sources such as farm yard manure (FYM), bio-fertilizer (BF), vermicompost (VC) were applied various doses along with recommended dose. We the treatments follows: T1= FYM (5 t.ha-1), T2= VC (2 T3= t.ha-1) + t ha-1), T4= PSB, T5= T6= T7= Control, T8= RDF through inorganic fertilizers (50:25:25 kg.ha-1 N, P2O5, K2O). use manures PSB significantly (P<0.05) increased rhizome yield soil-available macronutrients due release from decomposition manures. addition T6 resulted maximum canopy height (18.28 cm), plant fresh biomass (16.42 dry (3.19 weight (3.16 (1.16 well highest carbon content (0.75%), nitrogen (221 kg.ha-1), phosphorus (46.70 potassium (201 kg.ha-1). Applying FYM, vermicompost, combination strategy growing jatamansi.
