Effect of Different Levels of Soil Salinity on Vegetative Growth Indicators of Four Genotypes of Broad Bean Vicia faba L.

Abstract

Abstract A field experiment for the winter season (2022-2023) was carried out in the field of the Department of Crops / Faculty of Agriculture - Al-Qasim Green University, to find out the effect of different levels of soil salinity on vegetative growth indicators for four genetic structures of beans using the design of complete random sectors according to factor experiments, as the main panels included Genotypes (local, Turkish, Spanish, Dutch) while the secondary panels included three levels of soil salinity (2, 6 and 9 ds/m). The results indicated that there are significant differences at the level of probability of 5% of the studied qualities, as the Turkish variety outperformed the average vegetative growth, as it gave the highest average in the characteristic of plant height, number of branches, number of leaves, leaf area, root length and dry weight of the root system, either the local variety outperformed in the characteristic of the number of days of planting up to 50% flowering., leaf area, root length and dry weight of the root system, Compared to the salt level (9 ds/m), which achieved the lowest average of these traits, which differed significantly from the comparison treatment by achieving the lowest number of days of cultivation up to 5% flowering.
