This study was conducted in the experimental field of Agronomy Department, Faculty of Agriculture, Urmia University in 2017. The purpose of this study was, to examine the effect of foliar application of 3 levels macro nutrients (nitrogen, phosphorus, potassium)in different 3 levels dosage of these elements (2, 3 and 4g/1000) on yield and yield components of Fenugreek herb. Results showed that foliar application of macro nutrients was significant in plant height, number of pod, number of seeds per pod, pod length, 1000 grain weight, seed yield and biomass, seed nitrogen and protein percentage of Fenugreek. The highest grain yield (1029.2 kg/ha) and seed protein percentage (12.4%) were obtained in the nitrogen treatment. Also the lowest 1000-seed weight was achieved in control. The dosage of macro nutrients (excluding number of seeds per pod and seed yield) had a significant effect on the observed traits. The highest biomass yield (1574.17 kg/ha) was gained through 4g/1000, however the highest seed protein percentage (11.26%) was observed by 2g/1000. Therefore, foliar application method reduces utilization of chemical fertilizers, which can increase the efficiency of fertilizer application and decrease fertilizer nutrient losses.
