Nitrogen and Phosphorus Counteracted the Adverse Effects of Salt on Sorghum by Improving ROS Scavenging and Osmotic Regulation

Fertilizer management is one of the easiest and most practical ways combating salt stress. This study was done to evaluate alleviative effects nitrogen phosphorus on growth tolerance salt-affected sorghum. A controlled organized in a randomized block design with three replications conducted, testing rates (N0: 0 kg ha−1, N1: 180 N2: 360 N ha−1) (P0: P2O5 P1: 60 P2: 120 ha−1). Nitrogen application had positive morphological indexes (plant height, stem diameter), some physiological biochemical attributes (the content proline soluble protein, activities superoxide dismutase, catalase, peroxidase, ascorbate peroxidase), aerial biomass (fresh dry weight) sorghum grown saline soils. Reactive oxygen species accumulation cell membrane damage were decreased phosphorus. Compared sole fertilizer, combined showed better performance alleviating Despite fact that maximum measured parameters minimum reactive generally obtained at N1P1 N2P2 treatment, recommended be suitable treatment considering economic benefits environmental protection.
