Abstract
The present investigation entitled “Influence of different growing media on growth and flowering of chrysanthemum (Dendranthema grandiflora) cultivars for potmums” was carried out at Floricultural Research Station, Sri Konda Laxman Telangana State Horticultural University, Hyderabad during September 2018 to February 2019.
The experiment was conducted in factorial completely randomized design comprising 18 treatment combinations with 3 replications. The treatments consisted of 9 growing media G1: soil + sand + FYM (2:1:1), G2 : soil + sand + vermicompost (2:1:1), G3: cocopeat + sand + FYM (2:1:1), G4:cocopeat + sand + vermicompost (2:1:1), G5: soil + cocopeat + sand + FYM (2:1:0.5:0.5), G6: soil + cocopeat + sand + vermicompost(2:1:0.5:0.5), G7:cocopeat + soil + sand + FYM (2:1:0.5:0.5), G8: cocopeat + soil + sand + vermicompost (2:1:0.5:0.5), G9: control ( red soil ) with two cultivars Cv. Akitha and Cv. Redstone.
The growth parameters at 30, 60 and 90 days after planting, flowering, flower quality parameters were recorded and subjected to data analysis. Among different growing media G8 recorded maximum plant height (20.77, 24.03 and 28.40 cm), number of branches (3.10, 4.50 and 6.90), plant spread in N-S (13.51, 19.83 and 23.42 cm), plant spread E-W(14.04, 22.85 and 25.96 cm) at 30, 60 and 90 days after planting respectively, maximum number of fully opened flowers
per pot(30.25), number of flowers per pot (49.40), maximum flower diameter(4.30) , flower longevity (17.97 days )and duration of flowering (26.62 days) but G7 recorded minimum number of days for flower bud initiation (59.37), 50 percent flowering (103.14) and 100 percent flowering (118.71).
Among the treatment combinations C2G8 i.e. Cv. Redstone in cocopeat + Soil + Sand + vermicompost (2:1:0.5:0.5) recorded maximum plant height (19.93, 24.33 and 30.73 cm), number of branches (3.53, 5.07and 7.20), plant spread in N-S (14.83, 20.49 and 24.18cm), plant spread E-W(15.00, 24.03 and 28.32 cm) at 30, 60 and 90 days after planting respectively, maximum number of fully opened flowers per pot (32.17), number of flowers per pot (50.72), maximum flower diameter(4.56 cm) , flower longevity (18.73 days )and duration of flowering (27.80 days) but C2G7 i.e. Cv. Redstone in cocopeat + soil + sand + FYM (2:1:0.5:0.5), treatment combination recorded minimum number of days for flower bud initiation (49.13days ), 50 percent flowering(90.67 days) and 100 percent flowering (108.48 days).
The data on economics revealed that the treatment combination C2G8 i.e. Cv. Redstone in cocopeat + Soil + Sand + vermicompost (2:1:0.5:0.5) recorded highest benefit cost ratio (4.63:1) followed by C2G7 i.e. Cv. Redstone in cocopeat + soil + sand + FYM (2:1:0.5:0.5) (4.56:1) when compared to all other treatment combination.
It can be concluded from present investigation that among two cultivars Cv. Redstone responded well when compared to Cv. Akitha. The growing media G8: cocopeat + soil + sand + vermicompost (2:1:0.5:0.5) had shown significant difference in growth, flowering and flower quality attributes with highest benefit cost ratio among all other growing media.
