Abstract: (45 Views)
Planting date, nitrogen biofertilizer and weed control are three factors affecting biochemical traits of wheet in dryland condition, so an experiment was carried out as a split-factorel design with three replications on Kohdasht variety at Kamalvand research station in Khorramabad in two crop years 2015-2016 and 2016-2017. Planting date factor (6 and 21 November) was in main plots and nitrogen biofertilizer (control, urea, nitrogen biofertilizer, and combined fertilizer) and weed control (weeding and weed interference) factors were hn sub plots in factorial arrange. The results showed that the amount of phosphorus and potassium of shoots and seed potassium was significantly higher on the first planting date than on the second planting date, but the amount of proline and seed starch increased on the second planting date. Among the fertilizer levels, the highest amount of peroxidase and seed starch were observed from no application of fertilizer and the highest amount of seed nitrogen was observed from the application of combined fertilizer. The amount of peroxidase activity, seed phosphorus and seed starch in the weed interference treatment was significantly higher than in the weeding treatment, but on the contrary, the amount of shoot zinc, seed zinc and seed protein in the weeding treatment was more than the interference treatment. The highest amount of seed protein from the first planting date of combined and chemical fertilizer application (12.84% and 12.73%, respectively) and the lowest amount were observed from the second planting date and no application of fertilizer and application Chemical fertilizers (10.83 and 10.85%). The highest amount of chlorophyll a, b and total chlorophyll (5.51, 4.48 and 10.0 mg/g FW, respectively) and shoot phosphorus (0.49 percent) was observed from the application of combined fertilizer and weeding, the highest amount of proline and potassium of shoot was observed from the absence of application of fertilizer and weeding (8.3 mg/g FW and 2.96%, respectively) and the highest amount of seed potassium was observed from the application of combined fertilizer and interference (0.55 mg/kg). On the first planting date, the highest amount of shoot nitrogen was observed from the application of combined fertilizer and weeding (2.32%) and the highest amount of grain iron was observed from the pure or combined application of biological fertilizer and weeding (72.96 mg/kg); However, on the second planting date, the highest amount of aerial organ nitrogen was observed from the application of combined fertilizer and weeding (2.91%) and the highest amount of grain iron was observed from the application of biological fertilizer and weeding or interference (63.5 mg/kg).
