“…Application of potassium fertilizer is one of methods to improve the performance of plants under salt-affected soil conditions, as it had a vital role in regulating the vital processes in the plant and increases its ability to tolerance salt stress as well as its role in assimilate translocation from source to sink. In this regard, potassium fertilization had a major role in increasing yield and its components, according to a study of Hafiz and El-Bramawy (2012), Abdel-Rahman (2014), Jat et al (2017) and Ahmad et al (2018). The genetic potential of varieties has the greatest effect on salinity tolerance with increasing productivity under salt-affected soil conditions.…”

Improving yield and its components for some sesame genotypes using potassium fertilizer application under salt-affected soil was the desired goal of this study. So, for each site i.e. non-saline site, moderately-saline site and highly-saline site, the experiment was performed in a randomized complete block design (RCBD) using split-plot arrangement with three replications at the Investigational Farm of Tag-El-Ezz Agricultural Research Station, Dakahlia Governorate, Agricultural Research Center, Egypt during 2018 and 2019 successive summer seasons. Three levels of potassium fertilizer i.e. 0, 25 and 50 kg K 2 O fed-1 were assigned in the main plots and three sesame varieties i.e. Shandaweel 3, Giza 32 and Sohag 1 were arranged in the sub-plots. The main effects of sites, potassium fertilizer levels, sesame varieties and their dual and triple interactions were highly significant for all the studied traits. Shandaweel 3 was more salt tolerant variety and it was relevant to grow under salt stress. The potassium rate of 50 kg K 2 O fed-1 was found to be more efficient to mitigate salinity effect and increase yield and its components under salt stress. Therefore, Shandaweel 3 could be recommended under salinity stress with adding 50 kg K 2 O fed-1 to get high yield with high quality and nutrition value.
