An improved genetic algorithm was applied and examined to optimize the weights of a neural network model for estimating root length density (RLD) distributions of winter wheat under salinity stress. Thereafter, soil water and solute transport with root-water-uptake in a soil-wheat system were simulated numerically, in which the estimated RLD distributions were incorporated. The results showed t...

Distribution and growth of plant species is affected by many factors including abiotic (topography, altitude and soil) and biotic (root symbiosis) factors. In light of global warming, recent findings advocate microhabitats and micro-conditions of the root zone and canopy ambiance as determining factors in sustaining of plant populations. Although, occurrence of ectomycorrhizal (ECM) and non...

In this research, the effects of biochar application at different doses on mineral element content soybean seedlings under salt stress were investigated greenhouse circumstances. study, leaf and root some contents investigated. According to data obtained from it was stated that while plant nutrient decreased in salty conditions general, applied increased content. This positive effect treatments...

Pistachio is one of the economically important horticultural crops in Iran. The main pistachio-producing areas in Iran are located at the edge of the desert and are affected by soil and water salinity. Water and nutrient uptake by the root decreases under saline conditions. In this study, the effects of foliar growth regulators applied at different times on the nutrient uptake and leaf nutrient...

Successful irrigation management of tree and vine crops to control soil salinity requires adequate leaching, which is defined as sufficient water to remove excess salts from the root zone above that required to meet crop demand. Excess salts decrease growth and yield in trees and vines and may lead to more severe effects such as leaf bum and even plant death. The salt tolerances of many crops h...

BACKGROUND AND AIMS Water-saving ground cover rice production systems (GCRPS) are gaining popularity in many parts of the world. We aimed to describe the characteristics of root growth, morphology, distribution, and water uptake for a GCRPS. METHODS A traditional paddy rice production system (TPRPS) was compared with GCRPS in greenhouse and field experiments. In the greenhouse, GCRPS where ro...

in tunisia, kalâat el andalous irrigated district is one of the most affected areas by salinization. the objective of this study was to predict the root zone salinity (over 10 years) in this area using the saltmod simulation model for subsurface drainage system. saltmod is based on water balance, salt balance model, and seasonal agronomic aspects. in the pilot area, irrigated vegetables crops s...
