A field study was conducted during the winter season 2021/2022 cultivated with wheat (Triticum aestivum L.) on sandy soil at the experimental unit of the Faculty of Agriculture farm-Suez Canal University-Ismailia-Egypt. Results may indicate that the application of foliar chitosan NPs.-loaded nitrogen in different concentrations has been employed to enhance plant growth and productivity, Nano-chitosan loaded with N (500 mg/L) yielded the most grains and was more effective than the control and nano-chitosan loaded N (250 mg/L, 750 mg/L).展开更多

X-ray diffraction (XRD) analysis was done for the characterization and confirmation of the incorporation. Chemical analyses also indicate the sorption of fertilizer material into zeolite. An in vitro incubation study was conducted for 30 days at field moisture condition to see the release of the fertilizer materials and was compared with a conventional fertilizer. The release pattern of nutrients from either source showed a substantial decreasing trend with time although the release of P and K was higher for nano fertilizer than the conventional one. A pot culture experiment with Ipomoea aquatica (Kalmi) was also conducted to see the efficacy of the nano fertilizer in the growth promotion of the plant. Analysis showed higher accumulation of P and K in plants grown with nano fertilizer. Post-effect of nano fertilizer application in soil showed better pH, moisture, CEC, available P and K under nano fertilizer treatment than the conventional fertilizer.展开更多
