چکیده

In order to investigation of vermicompost effect on growth and yield of marigold in pot medium, an experiment was done by a randomized completely block design in three raplications. Treatmnets were included control (30% v/v of soil plus 70% v/v of sand) and three levels of vermicompost (20, 40, 60 % v/v of vermicompost+30% v/v of sand and soil) that applied in three lit. pots. Marigold seeds (Tagetes erecta cv. Tiashan) were planted in media. The shoots were cut and it was measured the bush heigh, the lateral branches, size and flower weight, dry weight of shoot, and the concertretion of nutrient elements. The results showed that added vermicompost to the growth media tend to improve the growth and yield of marigold than in the control. The Vermicompost (60%) had the highest weight, size and dry weight of shoot, but the maximum bush height was obtained by 20% vermicompost. The most lateral branches was belong to 40% vermicompost treatment. The results showed that the plants which cultivated on 60% vermicompost medium had the most amount of nitrogen, phosphorus and calcium. The most amount of potassium was ralated to 40% vermicompost treatment.
