In order to investigate the effect of shade, organic materials and planting time on characters of Lisianthus, a completely randomized design experiment was conducted in greenhouse of Isfahan University of Technology including 3 treatments, and each one consisted of 3 replications in 2012. Treatments consisted of two levels of 50% and 70% shade as the main factor, two planting times (April 28th and May 2nd) as sub-factor and three levels of organic material ( 0, 5 and10 kilograms of manure per square meter) as sub-factor in subsidiary. The results showed that 50% shade increased height, diameter of flower, the amount of chlorophyll and fresh and dry weight of the plant. The longest flowering period was observed in treatment of 50% shade. Plants in this treatment produced flower faster than those in 70% shade. The first planting time (April) fell behind in blooming but beared flowers for a longer time. Also, leaves showed less chlorophyll compared to those planted in May. Planting time had no significant effect on other characteristics. Organic material showed a significant effect only on wet and dry weight of plants. Interacting effect of shade and organic material showed a significant effect on Lisianthus’s fresh and dry weight and amount of relative chlorophyll. But the intraction between planting time, shade and organic matter effected dry weight and fresh weight respectively.
