Abstract :

        Amaranth is a crop belonging to the genus Amaranth. This genus includes about 60 species of wild Amaranth that are majority. Some of them as crop food and some of them are used as ornamental crop. But the majority of them are weeds without applied.The amaranth seed proteins contain most of essential amino acids that other plants lack like such as lysine. However, one of the most important factors affecting its yield and quality is the plant nutrition and fertilizers on which managing nutritional elements influence greatly.  Treatment this study was elements( iron, nitrogen, zinc, and manganese), amount application(100,200, 300 kg/ha of Nitrogen and 3,5 and 7 in thousand Iron, Mn and Zinc) and time of application. The results showed that different levels of nitrogen fertilizer increased the features. The highest of these effects was observed after application of iron, nitrogen and zinc fertilizers by application 2 and 3) and. The study showed that had significant increase in the features of height, number of seeds. However, in case of the number of the seeds several stages of treatment induced similar increases in comparison with application in planting amounts. According to the findings of the present study, treatment of 200, 300 kg/ha nitrogen showed 11.32 and 9.98 % increases in the seed number respectively. Maximum seed number by 7 in thousand application Zinc was 8464 that 3.37 % than control increased. According this experimental application of fertilizers improve qualitative and quantitative features of amaranth.
