| Abstract | ||
| The SSIMOD assumes that time and/or depth is moisture. Accordingly, under deficit irrigation, the soil moisture regimes should be adopted without causing a reliable change in crop yield and plantations depend on four newborn abiotic stress parameters. The abiotic stress parameters are dependent variables of the geotempospatial signals' interaction. A strong correlation between soil stress index and plant stress index was found. As the plant stress index is the dependent variable of the soil stress index, values of the plant stress index were predicted using the corresponding values of the soil stress index. Discretization equations between SSI and PSI were created in one and two dimensions. The stress form of Richard's equation in tempospatial variabilities was solved using the finite volume approximation. Relativity and hysteresis were found and discussed using the optimal approaches of modeling. The root water and nutrients uptake, SSI, PSI, bz, and bt exhibited intrinsic variabilities. These hysteric effects may be attributed to the geosignal of total soil water energy. Silicon foliar application is a common managerial practice under such environmentally abiotic stressed conditions. Silicon enhances the plants' moisture status under combined drought and saline conditions | ||
