تأثیر مقادیر مختلف نانو ذرات پتاسیم بر تجمع تنظیم کنندههای اسمزی و عملکرد دانه سویا

To evaluate the effect of different rates of Nano-potassium on the proline, total soluble carbohydrates and seed yield of soybean a field experiment was conducted based on randomized complete block design with three replications at the research farm of Shahid Beheshti Agriculture College in 2013. Treatments were eight levels of Nano- potassium: included 0, 5, 10, 15 kg/ha soil application, and water spray, 1, 2 and 3 g/l spraying of Nano-potassium particles. Results of ANOVA showed the significant effect of Nano potassium on the leaf proline accumulation and seed yield. The highest leaf proline content (65.14 mg/l) was obtained from plants treated by 15 kg/ha soil application of Nano-potassium, and the lowest proline (26.72 mg/l) belonged to plants treated by 5 kg/ha Nano-potassium. The highest (27.767g/plant) and lowest (14.843 g/plant) yield of seed were obtained from 10kg/ha Nano-potassium and water spraying, respectively.
