Influence of integrated nutrient management on dry matter production and flowering in Davana (Artemisia Pallens Wall.)

An experiment was conducted during the year 2011-12 to study the influence of integrated nutrient management on growth and yield of Davana” at College of Horticulture, Mudigere, Karnatakaka. The dry matter production and days taken for 50 percent inflorescence differend significantly among the treatments. Application of 75%RDF + Azospirillum 2 kg ha-1 (T5) recorded significantly maximum fresh weight of leaves (7.02 g), which was on par with  T12  (6.91 g). Application of 50%RDNPK + Vermicompost 2.5 t ha-1 + Azospirillum 2 kg ha-1 + PSB 2 kg ha-1 (T12) recorded maximum dry weight of leaves (3.12 g), fresh weight of shoot(29.56 g), dry weight of shoot (6.40 g), fresh weight of root (4.57 g), weight of root (1.15 g). The plants provided with 75%RDF + Azospirillum 2 kg ha-1 (T5) took minimum number of days (58) for 50% inflorescence which was on par with T12 (58.67)
