Ensuring food security under climate change scenario requisites amending degraded soils and sustainably boost staple crops yield in a biologically viable way through effective plant nutrition management strategies. Two multi-year field experiments at Sakha Agricultural Research Station, Kafr El Sheikh, Egypt, were conducted to investigate the impact of vinasse and foliar application of compost tea on physico-chemical soil properties and yield of wheat in salt affected soil (2020/2021 and 2021/22 winter seasons). The experiment was executed in split plot with three replicates having vinasse (V):0, 30, 60, 90 and 120Lfed.1 treatment in main plots while sub plots had foliar application of (without compost tea (CT-) and with compost tea (CT+).The results showed that physico-chemical properties (bulk density, porosity cation exchange capacity, electrical conductivity, exchangeable sodium percentage etc.) and fertility (available of Nitrogen, Phosphorus and Potassium) of the soil were significantly influenced by all levels of vinasse, however co-application of vinas an foliar application of compost tea remained unmatched. The same treatment combination also remained effective in boosting nitrogen and protein in grain along with wheat yield during both seasons. With foliage applied compost tea remained superior by recording the highest yield attributes and grain yield of wheat. Therefore, it is inferred that co-application of 120Lfed.1 and foliage applied of compost tea could be developed as an effective approach to restore and conserve the soil and increase wheat productivity in salt affected soil environment arid and semi-arid regions.
