Investigation of Media (Vermicompost, Peat and Coco- Peat) on Growth and Flowering of Carnation Flower

An experiment was conducted to investigate the effects of some media (vermicompost, peat and coco- peat) on the growth and flowering quality of carnation flower, based on completely randomized design with 10 treatments and 8 replications in Sarein’s Municipal research greenhouse in 2010. Various levels (20, 40 and 60 percentages) of each these materials were used in this experiment as experimental treatments. Leaf number, plants height, shoots and flower diameter were studied. Plants treated with 60% vermicomoost were died, hence, neglected in statical analysis. Also, results has shown that vermicompost treatments had unfavorable effect on all of experimental criteria, which at 20 and 40% significantly decreased leaf number, plant height, shoot and flower diameter. Coco-peat at 20% enhanced leaf number and plants height, but at 40 and 60% decreased leaf number, plants height, shoot and flower diameter. But this compound at 20% increased shoot and flower diameter significantly (P<0.05). Peat treatments increased leaf number, final leaf number in peat treatment were either more or equivalent to control, But there was no significant difference between peat treatments and control. Peat at 60% in comparison to 20 and 40%, increased shoot diameter. In case of flower diameter, biggest flower devoted to peat 20% in first stages of flowering time, but the biggest final size of flower observed in peat 40% treatment. Hoewer, in this experiment, coco-peat at 20% and peat at 20% had positive effects on growth and development of carnation compaired to control and other treatnents.
