Abstract only

Solonetzic soils that are low in sodium content are considered as one of the main resources of increasing the sowing areas in Georgia. They cannot be used for cereals and other plants cultivation without radical land melioration. The major goal of this research was to assess impact of the different chemical meliorants on cereal yield. Low-sodium solonetzic soil was the object of the research. In the trial where chemical melioration was carried out, winter wheat and maize for silo were planted at the rate of250 kg/ha and 40 kg/ha, respectively. Three years of research showed that the highest yield increase was observed for soil melioration by defecator. As measured during three years, average maize biomass yield for this treatment was 28.9 t/ha that is higher than that ofthe check by 4.6t/ha. The average yield of winter wheat was 2.95 t/ha that is higher than that of the check by 0.85 t/ha. From the economic point of view, the best results have been achieved when defecator was applied. As compared to the check, cost-efficiency of production increased up to 67.3%, when defecator was applied. It is recommended winter wheat be sown after soil melioration and followed by maize for silo as the second crop.
