2013
Varmā, Jītendra | Rao, VK
A field experiment was carried out to see the effect of integrated nutrient management on growth, yield of strawberry cv. Chandler and nutrient status of soil under mid hill conditions of Uttarakhand with twelve treatment combinations comprising of inorganic fertilizers (N: P: K), biofertilizers (Azotobacter and PSB) and organic manures (FYM and vermicompost) replicated thrice with 20 plants per replication in randomized block design. Observations were recorded for vegetative growth, fruit yield and chemical properties of soil. Treatment receiving Azotobacter + PSB + vermicompost + 50% recommended dose of NPK recorded highest plant height plant spread, leaf area per plant. Plant supplied with Azotobacter + PSB + vermicompost + 50% RDF registered earliest in flowering and fruit maturity and highest number of flowers per plant and flowering duration. The maximum fruit weight, number of fruits per plant, yield per plant (181.84 g), marketable yield per plant (145.47 g) and yield per hectare (101.02 q) were recorded with plants treated with Azotobacter + PSB + vermicompost + 50% RDF followed by Azotobacter + PSB + FYM + 50% RDF treatment. The application of Azotobacter + PSB + vermicompost + 50% RDF was found to more effective in decreasing the electrical conductivity (0.02 dSm⁻¹) and pH (6.27) of soil. The organic carbon (1.95%), available nitrogen (314.64 kg ha⁻¹), phosphorous (17.56 kg ha⁻¹) and potassium (306.33 kg ha⁻¹) were recorded significantly higher in soil after harvest of the crop in treatment receiving Azotobacter + PSB + vermicompost + 50% RDF.
