Abstract
Field experiment was conducted at Medicinal Plant Research and Development Centre, (Haldi), G.B.Pant University of Agriculture & Technology,
Pantnagar during Kharif season of 2005 06 on sandy loam soil with neutral pH, 0.8% organic carbon and 186.59, 22.85 and206.36 kg/ha available N, P and K, respectively to study the Effect of vermicompost and biofertilizers on Performance of Lemon Tulsi (Ocimum basilicum L) under Tarai condition of Uttarakhand. The experiment was conducted in the Randomized Block Design (RBD) with three replications. The total treatments were 10 consisting of two levels of vermicompost (VC) i.e. 5 and 10 t ha-1 along with biofertilizers i.e. Azotobacter (AZT), Azospirilium (ASP) and Phosphate solubilizing bacteria (PSB). Significantly higher fresh herbage yield was recorded with the application
of Vermicompost 10 t ha-1 + Azotobacter. Treatments consisting of vermicompost @ 5 t ha-1 gave 7.6 and 17.9 % higher herbage yield than control treatment. The combined application of Vermicompost @ 5 t ha-1or 10 t ha along with biofertilizers produced on an average 5.5 and 4.1 % higher herbage yield, respectively than alone application of vermicompost separately. The higher values were attributed to higher growth parameters including plant height, fresh and dry weight accumulation per plant and leaf: stem ratio. Significantly higher oil content in plant parts as well as total oil yield were recorded when 10 t ha-1 Vermicompost was applied along with root treatment with PSB. Application of Vermicompost @10 t ha-1 + Azotobacter facilitate significantly higher n and K uptake while Vermicompost @ 10 t ha-1 + PSB gave higher P uptake. Similarly, the application of Vermicompost @ 10 t ha-1 + biofertilizers had higher values of residual organic carbon and available N, P
and Kin soil. All growth parameters and N, P and K uptake were found significantly positives correlated with fresh herbage yield as well as oil yield. Therefore, organic Lemon Tulsi (Ocimum basilicum L.) may be grown successfully with combined application of 10 t ha-1vermicompost and biofertilizers for higher herbage and oil yield with sustained soil fertility in Tarai region of Uttarakhand.
