Abstract
Supporting calcareous soil with soil amendments is critical to promote plant growth and enhance crop productivity. The application of potassium sulfate has been well documented to have a potential role in this regard but information on the potential of varietal responses is scarce. Therefore, the current investigation was designed to test the effect of different application rates of potassium sulfate (0,210 and 420kg/ha) in the form of potassium sulfate on the growth and yield attributes of five newly released faba bean cultivars (Sakha-1, Nubaria-4, Nubaria-5, Giza 716, and Giza 843) under calcareous soil conditions. The results showed that faba bean cultivar Nubaria-5 recorded the highest value for plant growth, yield and its component traits, Also, it recorded the highest value for nitrogen, phosphorus, potassium, and sulfur percentages in the plant shoots and seeds during the winter growing seasons of 2021/2022 and 2022/2023. The cluster analysis showed that Nubaria-5 appeared in a separate group, confirming its dissimilarity to the rest of the Varieties used. In conclusion, varietal variation exists and it may be employed in conjunction with sulfur amendments in the strategy plan for enhancing faba bean crop productivity in calcareous soil.
