摘要：Ensuring food security under climate change scenario requisites amending degraded soils and sus-tainably boost staple crops yield in a biologically vi-able way through effective plant nutrition manage-ment strategies. Two multi-year lysimeter experi-ments were conducted to investigate the impact of soil organic substances and foliar application of some nano-nutrients on soil properties and wheat yield under saline conditions. The experiment was executed in split plot with three replications. Treat-ments included organic amendments (molasses, compost tea, K-humate, molasses+ compost tea, mo-lasses+K-humate, compost tea+ K-humate and mo-lasses+K-humate+Compost tea and control)in main plots, while sub plots had nano-micronutrients (nano-selenium, nano-manganese and nano-silica)and a control treatment. The results showed that physio-chemical properties(bulk density, cation ex-change capacity, electrical conductivity etc.)of the soil were significantly influenced by all organic amendments; however, co-application of molas-ses+K-humate+compost tea remained unmatched. The same treatment combination also remained ef-fective in boosting nitrogen uptake and recovery along with wheat yield during both seasons. Among foliage applied nano micronutrients, silicon re-mained superior by recording the highest yield at-tributes and grain yield of wheat. Therefore, it is in-ferred that co-application of organic amendments and foliage applied nano-fertilization management could be developed as an effective approach to re-store and conserve the soil and increase wheat productivity under saline environment of arid and semi-arid regions.
