Effect of Nitrogen and Biological Bacteria on Yield, Nutrient Concentration, and Total Nutrient Uptake of Wheat Shoot

To investigate the effects of nitrogen and Nitroxin bio-fertilizer application on yield، nutrient concentration، and total nutrient uptake in wheat shoots، a greenhouse experiment was carried out in a factorial completely randomized design with three replications. Treatments included two levels of Nitroxin (0 and 10 ml/kg of soil) and five nitrogen levels (0، 50، 100، 150، and 200 mg/kg of soil). Results showed that Nitroxin application significantly increased yield as well as the concentration and total nitrogen uptake، uptake of phosphorus، iron، and manganese in wheat shoots. Application of nitrogen increased yield، total uptake of nitrogen، potassium، iron، zinc، manganese، and copper as well as the concentration of nitrogen، potassium، zinc and manganese of wheat shoots، however، total uptake and concentration of phosphorus was reduced significantly. According to these results، combined use of nitrogen and Nitroxin is suitable for achieving the maximum yield of wheat shoots.
