For this purpose, factorial experiments in fully randomized design were conducted during the year of 1999 growing period. The data obtained have been evaluated on the yields of physical and chemical quality. There is no change on the yields of dry plant by increasing irrigation water salinity. Although the yields of green plant and the number of sub-brunches have seriously decreased, the yields of biomass and the total ash have increased. The natural height of the plant and the height of main branch have been negatively affected by the quality and quantity of irrigation water. The radius of the branches and the number of sub-branches have been negatively affected by high level of salinity of the irrigation water (6 dS/m). Moreover, the yields of protein has scantly increased on low level of the salinity of the irrigation water. Water content of the soilhas also affected the yields of the plant. Saving the water content of the soil on the level of 100% has especially made the yields of the plant increase. 2001, Page: 46 KEY WORDS: Vicia pannonica, irrigation water salinity, plant yield and quality, soil salinity.trTarımsal Yapılar ve SulamamasterThesis
