Impact of integrated nutrient management on growth and yield of davana (Artemisia pallens Wall.) under hill zone of Karnataka

An experiment was conducted during the year 2011-12 to to study the influence of integrated nutrient management on growth and yield of Davana” at College of Horticulture, Mudigere, Karnatakaka. At 75 days after transplanting significantly taller plants (45.18 cm) were found in plots receiving 75%RDF + Azospirillum 2 kg ha-1 (T5). The maximum number of leaves per plant (147.16), laterals per plant (19.49), stem girth (1.41 cm),  were registered in 50%RDNPK + Vermicompost 2.5 t ha-1 + Azospirillum 2 kg ha-1 + PSB 2 kg ha-1 (T12), which was on par with T5 - 75%RDF + Azospirillum 2 kg ha-1   . Fresh herbage yield per plant differed significantly due to integrated nutrient management. Application of 75%RDF + Azospirillum 2 kg ha-1 (T5) recorded the significantly maximum fresh herbage yield per plant (20.64 g), which was on par with T12 (20.63 g) and T11 (18.83 g). Whereas, significantly minimum herbage yield was recorded (13.24 g) in RDF + PSB 2 kg ha-1 (T4).
