Abstract: Developing an alternative method for productive farming on saline soils is necessary because remediating the soils is not feasible on-farm. A foliar application of liquid-silicate rock fertilizer (LSRF) was proposed in response to this need, and its effectiveness was evaluated in a greenhouse. The specific aim of the research was to identify the effects of LSRF on the growth and yield components of soybeans grown on salinized soils. The experiment employed a split plot in a completely randomized design, with the main plot consisting of soil salinity levels (EC), i.e., 0.5, 1.5, and 2.5 dS. m-1 and the sub-plot was the concentration of applied LSRF, i.e., 0, 1, 2, and 3 %, in triplicates. Results reveal an increase in soil EC to 2.5 dS. m-1 slowed down the growth rate and reduced the yield of soybeans by about 20 %. In contrast, applying LSRF at concentrations ranging from 1 to 3% improved soybean growth and yield components while reducing the severity of soil salinity’s effects on the plant. Foliar application of LSRF could be an effective method of reducing the stresses caused by saline environments in soybeans. How to Cite: Joko Priyono, Akhmad Zubaidi, 2023.
