Abstract: 

Degen & Drfiis a plant that has medicinal and nutritional importance. Degen& Drfi and countless of plants in this genus had application for medicinal uses such as weight loss and diabetes control. Its seeds also contain protein and lipids as well as some starchy foods are consumed. In order to investigate the effect of irrigation regime and planting date on agronomic characteristics of Degen& Drfi a field experiment carried out in region of kahi, Birjand, south khorasan, Iran, 2010. The experiment was conducted in split plot design in a randomized complete block with four replications. Irrigation regime, including: six, twelve and eighteen days' intervals as main factors and planting Date at four levels (20, 25, 30 April, and5 May) were devoted to sub-plots. Analysis of variance showed that irrigation regime for all treatment, had more significant influence on trait including plant height, number of pods per plant, seeds per pod, biomass, grain yield and harvest index, and had significant influence the yield of flowers per plant and weight seed. The highest amounts of each trait were gained from 12 days interval irrigation. The effect of planting date was significant all treatment for all traits except 1000-seed weight. Planting in 20 April had highest values of characteristics. Interaction between irrigation and planting date were significant for number of stems, flowers and pods per plant, biomass, harvest index and grain yield at 1% and plant height at 5% level. The highest seed yield was obtained from irrigation in 12 days interval and planting in the 20 April. Results showed that irrigation in 12 days interval and planting especially in late April are the best treatment for Degen & Drfi production.
