Abstract:   (2558 Views)
In order to study the effect of humi potas and potassium sulfate on some morphological traits of Stockflower, this research was conducted at Research Farm of Shahid Chamran University in Ahvaz in 2015. This experiments was performed as factorial bassed on RCBD with three replications. Treatments included humi potas with 3 levels of 0, 500 and 1000 mg l-1 and potassium sulfate fertilizer with 3 levels 0, 50 and 100 kg / h. During growth period, Evaluated vegetative indices (length and diameter of stem, number and leaf area) In 6 stage at intervals every 21 days once and reproductive characteristics (Flower durability, number of days to flowering and seed yield per square meter) at the end stage of plant growth.Treatments with Humi potas were effective on the vegetative properties of stem diameter, leaf number and leaf area, and on the reproductive characteristics of days to flowering and Flower durability. Treatment with potassium sulfate was significant only on stem length and diameter characteristics. the interaction of Humi potas fertilizer and potassium sulfate also showed a significant effect on the growth characteristics of stem diameter, number and leaf area, Flower durability and seed yield. The highest stem diameter, number of leaves, leaf area and Flower durability were related to interaction treatment (1000 mg/l Humi potas and 100 kg/ha potassium sulfate). Overall, it can be said that the use of Humi potas fertilizer in combination with potassium sulfate fertilizer, in addition to improving the growth characteristics of Flower, can play a positive role in decreasing the use of chemical fertilizers and reducing environmental pollution.
