Influence of Bio Fertilizers and Foliar Spray of Spermine and Vermiwash on Growth, Yield and Postharvest Quality of Gerbera (Gerbera jamesonii Hook.) Under Naturally Ventilated Polyhouse

Year: 2017

Type: article

Abstract: An experiment was conducted during 2013-2015, with factorial concept to study the influence of soil inoculation of bio fertilizers (Azotobacter @ 1l/ha and VAM @ 2 g/plant) and foliar application of chemicals (spermine and salicylic acid @ 25 and 50 ppm each) and organic growth enhancers (banana pseudo stem sap @ 0.5% and 1% and vermiwash @ 4%) on gerbera. Pooled data of two years indicated that the treatment combination of bio fertilizers along with the foliar spray of spermine @ 25 ppm showed maximum plant growth parameters viz., plant height (42.87 cm), leaf area index (4.72), suckers per plant (8.42), flower parameters viz., yield per plant (57.17), diameter (11.41 cm) and fresh weight (25.11 g) of the flower and physiological parameters like membrane stability index (75.50 %), protein content (30.73 mg/g) and peroxidase activity (48.19 mM/min/g protein) in the petal tissue and postharvest life (9.29 days) of gerbera which was at par with or followed by the treatment combination of bio fertilizers along with the foliar spray of vermiwash @ 4%. Thus, these treatment combinations significantly influenced the growth, yield as well as postharvest quality and life of gerbera.
