ABSTRACT
A field experiment was conducted at a private farm of M/s. Salem Green Plants Limited, Yercaud during the year 2011 – 2013 to find out the effect of growing media consortia on growth, physiology and yield of chrysanthemum var. Amalfi under greenhouse conditions. The experiment was laid out in a Randomized Block Design (RBD) with three replications. Treatments consisted of T1- Soil alone(control), T2-Soil +F YM(Growers practice), T3- Soil + FYM+ Coco peat + Microbial consortia, T4- Soil + FYM+ Perlite + Microbial consortia, T5- Soil + FYM+ Vermicompost + Microbial consortia, T6- Soil + FYM+ Coco peat + Perlite + Microbial consortia, T7- Soil + FYM+ Coco peat + Vermicompost + Microbial consortia, T8- Soil + FYM+ Perlite + Vermicompost + Microbial consortia and T9- Soil + FYM + Coco peat + Perlite + Vermicompost + Microbial consortia. Observations were recorded on growth, physiology and flowering parameters at peak vegetative, bud appearance and peak flowering stage. The results revealed that T9 recorded the highest plant height (46.09 cm, 78.70 cm and 98.33 cm), number of leaves (26.73, 38.82 and 39.72) at critical stages, internode length (3.95 cm), root length (13.43 cm), earliness in flower bud appearance (44.29 days) and days to harvest (81.41 days) than control (56.28 days and 104.08 days). Physiological traits include leaf area per plant (58.81 cm2, 62.09 cm2 and 65.53 cm2) and total chlorophyll content (1.72 mg g-1, 2.34 mg g-1, 2.47 mg g-1) was found best at all the stages in T9. This treatment also recorded the highest flower stalk length (95.22 cm), flower stalk girth (3.52 cm), unopened and opened flower bud circumference (4.15 cm and 8.20 cm), number of quality grade cut stems (71.21 A grade, 1.53 B grade, 3.83 C grade) and marketable flower stalk yield per sq.m (76.57 cut stems). The study indicated that the growing media consortia containing Soil + FYM + Coco peat + Perlite + Vermicompost + Microbial consortia was found to be better in enhancing and sustaining the productivity per unit area under protected conditions.
