Abstract
In our studies, gypsiferous soils were compared with garden soil. Five research groups were formed with gypsiferous soils from Middle Anatolia of Turkey. When plant lengths were compared in all groups, there was a decrease in gypsum. When the results were evaluated according to weights, there was a decrease in root weight in all groups compared to control soil and when spike weights were evaluated, there was a decrease of 17.57% in gypsum. Maximum seed weight per root was found to be in control group. When all groups were evaluated in terms of total chlorophyll content, the gypsum + soil mixture groups had more photosynthetic chlorophyll content than control. As for harvest, the best development in stem length, spike weight, seed number per root and seed weight per root were observed in soil without gypsum. Better yields in 100 seed weight, spika lenght, root weight and root lenght were observed in wheat groups where low gypsum mixtures were used. There was a decrease in amounts of salt (%) and beneficial K20 in all study groups at harvest when compared with the beginning values, whereas organic material and CaCO3 (%) amounts increased.
