NANOPHOSPHORUS FOR IMPROVING FODDER BEAT GROWTH UNDER SALINITY STRESS CONDITIONS | PLANT CELL BIOTEC

Application of nanotechnology in agriculture under stress is a significant step forward, but more work is needed to fully understand its benefits and risks. In this regard, a pot experiment was conducted in the greenhouse of the National Research Council (NRC), Dokki, Giza, Egypt, to investigate the responses of some growth parameters, photosynthetic pigments, and nutrient content of fodder beet plants (at mid-season) to nanophosphorus (nano P) fertiliser application under various salinity levels.In addition to tap water (TW= 257 ppm), two rates of diluted seawater (S1=3000 and S2=6000 ppm) were used for irrigation (S1=3000 and S2=6000 ppm).Aside from distilled water as a control, two concentrations of nano P (n-P1=0.5, n-P2=1.0 gL-1) were sprayed (C).

While spraying nano P fertiliser improves root length, fresh and dry weight of root and whole plant, chlorophyll a and chlorophyll a+b, leaves number, root diameter, fresh and dry weight of top, nutrient concentrations (N, P, K, Ca, Na percent ) and content, chlorophyll b and carotenoids in plant top (mg/plant), and nutrient concentrations (N, P, K, Ca, Na percent ) and content It is suggested that further research be done on the impact of nano-P versus traditional fertilisers on the environment.
