Root and Shoot Relation of the Quinoa and Forage Plants in Salt-Affected Clay Soil

Allometric Model for Predicting Root Biomass of Field Crops in the Salt-Affected Clay Soil: Novel Approach

“…approximate estimation is acceptable for the desired stra six annual crop species and a better generalized model The largely recognized relations between the hei could also be used for herbaceous plants with small ver field crops [8,10,[12][13][14]. Therefore, if the effect of plant g various environmental conditions, the allometric mod (and nutrient) stress, plant tolerance level, and the inp studied region, the root to shoot ratio of annual field c the abiotic stresses associated with the elevated salinit The order of the RM was somewhat opposite to the roo ghum or maize were crops more resistant to the combin The cropping improved SOC content and aggrega higher under crops than in the control (Figure 2).…”

“…Irrigation rate was traditional (70% of full irrigation frequently applied by farmers) due to the fresh water shortage. Root samples were collected (3 × 45 = 135 samples, 0-40 cm depth) using a monolith excavation method at the harvesting stage [7,14].…”

“…An ANOVA was conducted to compare the role of crop species on vegetative parameters, and mean comparisons were made by the Tukey HSD (p < 0.05). Least squares fitting was used to evaluate the allometric relation (linear, exponential or power) between the RM and the CD [9,10,14].…”

“…Such methods could be useful for agricultural annual crops as well, yet regardless of the approach used, it is necessary to measure the root system directly. The ability of crops to adapt to the environment and abiotic stress conditions affect crop organ mass fraction in both trees and annual crops, and become evident in the parameters of allometric relations [8][9][10][11][12][13][14]. Therefore, the objective of the study was to develop an allometric model to predict the root biomass of crop species using a root collar diameter, one of the most easily measured crop parameters.…”

Differential Impact of Salinity Stress on Seeds Minerals, Storage Proteins, Fatty Acids, and Squalene Composition of New Quinoa Genotype, Grown in Hyper-Arid Desert Environments

“…There are more than 3,000 quinoa ecotypes whose potential and nutritional value have not been explored outside the Andes. Many studies have been performed to analyze the tolerance of different quinoa genotypes to abiotic stress in terms of its agronomic performance ( Adolf et al, 2013 ; Ruiz et al, 2016 ; Mamedov et al, 2020 ), whereas a few have been conducted to explore the effects of high salinity response on the nutritional profile of quinoa seeds ( Sampaio et al, 2020 ).…”
