Abstract
The main purpose in the two experiments were conducted to study the effect of halophyte (Portulaca oleracea L.) on nutrients in saline soils and their comparison. In the first experiment, the effect of salinity on growth, biomass accumulation, yield, root layer development, salt accumulation, as well as the dynamics of mineral matter changes in plants and soil was studied. In the second experiment, seeds of a halophytic plant (P. oleracea) were planted directly into saline soil and the amount of nutrients in its leaves and in the soil was determined. Three different salinity levels (saline water solutions (T1 - 5 dS m−1; T2 - 9.8 dS m−1; T3 - 20 dS m−1) and a control variant (T0 - 1 dS m−1) were selected for the first experiment. Soils selected for the second experiment were used in the first experiment (soil salinity level: T1 - 7.2 dS m−1; T2 - 8.8 dS m−1; T3 - 15.6 dS m−1; T0 - 1.9 dS m−1)). This is confirmed by the yield (dry matter) obtained from halophyte under highly saline soil conditions. At the same time, the effect of halophyte on nutrient uptake in soil under highly saline soil treatment was established.
