Proper nutrient management is important to reduce yield losses due to salinity. In the present study response of two wheat genotypes was studied when foliar Zn and K were applied (0.2% of Zn, K and Zn+K) along with soil application (25+100 kg ha-1 of Zn+K) at the vegetative and reproductive stage. First experiment was conducted in pots and its results were further confirmed in saline field of Biosaline Research Station, Pakka Anna. Salinity significantly reduced all yield attributes. However, application of Zn+K through soil and foliar means significantly improved the plant height, productive tillers plant-1 , fertile spikelets spike-1 , spike length, 1000 grain weight, plant biomass and grain yield. Plant height and biomass were significantly increased by foliar application of Zn+K at reproductive stage. Application of Zn+K through soil and foliar was helpful in alleviating the adverse effects of salinity stress at both vegetative and reproductive stages of wheat. Among nutrient combinations, the Zn+K were the most effective treatment for both cultivars under salinity stress. In summary cultivar selection and nutrient application are effective strategies to improve wheat grain yield under salinity stress.
