Growth, Yield, quality and economics of chrysanthemum as influenced by foliar application of biostimulants under naturally ventilated polyhouse

An experiment was conducted to know the influence of biostimulants on growth, yield, quality and economics of chrysanthemum under naturally ventilated polyhouse at department of Floriculture and Landscape Architecture, College of Horticulture, Mudigere during 2015-16. 12 biostimulant formulations in 2 different concentrations were used for the study. Among different biostimulant treatments application of Biovita @ 0.5% at 60, 90 and 120 DAP resulted significantly maximum plant height (66.83 cm), number of leaves (82.95), stem diameter (7.30 mm), number of flowers (92.15) flower yield per plant (424.09 g), flower yield per square meter (4.05 Kg), flower yield per hectare (40.50 t/ha), sucker yield per plant (9.85), individual flower weight, flower diameter, stalk length (46.89 cm, 5.06 g and 6.70 cm, respectively) vase life (22.5 days) and shelf life (11 days) with highest net returns and B:C ratio ( 3, 12, 411.07 and 4.43, respectively). Whereas, the lowest values for all the above parameters were recorded in control (RDF).
