Abstract
In order to investigate the effects of sources and different amounts of nitrogen fertilizer on some morphological traits of fenugreek, an experimental study was conducted as a randomized complete block design with four replications in the summer of 2015 in the experimental farm of Ilam University Horticulture Department. Experimental treatments included urea and calcium nitrate fertilizers at four levels of zero, 25, 50 and 100 kg / ha and amino acids with four concentrations of zero, one, two and four g / l. Measured traits included plant height, number of branches, number of pods per plant, pod length, number of seeds per pod, leaf area, shoot fresh weight, shoot dry weight, root fresh weight and root dry weight. The results showed that the effect of different sources and amounts of nitrogen on the number of seeds per pod and pod length in fenugreek was not significant, but had a significant effect on other traits. The highest fresh and dry weight of shoots, fresh and dry weight of roots, number of branches and leaf area of ​​100 kg / ha calcium nitrate treatment, highest plant height of 100 kg / ha urea and highest number of pods per plant of treatment Amino acids 4 per thousand were obtained. The results of this study showed that the use of different sources of nitrogen fertilizers has a positive effect on improving the morphological traits of fenugreek and nitrogen consumption can be recommended to increase the quality of this vegetable and medicinal plant.
