The study involved in testing the effects of two amended organic media (loam + sheep manure and loam + peat moss (1:1)) and different concentrations of seaweed (sea force 2) extract including (0, 0.5, 1, 1.5 and 2 mL/L) on growth and flowering of Periwinkle (Vinca rosea) plant. The results showed that growing vinca plants in peat moss medium and spraying sea force 2 extract with low concentrations especially 0.5 mL/L resulted in positive significant difference in vegetative and flowering characteristics.展开更多
