Abstract :
To evaluate the effect of irrigation with purified domestic wastewater and foliar application of urea on some qualitative and essence percentage traits of fenugreek, an experiment was conducted in factorial experiment based on completely randomized block design with three replication. Factors of the experiment were the purified domestic wastewater (0, 50 and 100 mg/l) and the foliar application of urea (0, 3 and 6 percent). The evaluated characteristics were: essence yield, essence percentage, nitrogen uptake percentage, phosphorus uptake percentage, potassium uptake percentage and protein percentage in shoots of fenugreek. The results displayed significant differences (p<0.01) between all of the measured traits in different levels of foliar application of urea and wastewater application and their interactions. The highest and lowest essence yield (12.59 kg/ha) and essence percentage (0.49) were obtained in 6 % urea and no consumption of urea. The most essence yield (12.54 kg/ha) and essence percentage (0.52) were observed in 100 mg/l purified domestic wastewater. Application of 100 mg/l purified domestic wastewater plus 6 % urea had the most essence yield (13.38 kg/ha) and essence percentage (0.53), also the control showed the least average of traits.
