“…Net assimilation rate according to Aslani et al,(2020) and Li et al, (2016) is strongly influenced by the spread of sunlight on the plant canopy, the existence of leaves that shade each other will reduce the NAR value. This opinion is in accordance with the statement of Orzech et al, (2022) and Samidjo, (2021)that the net assimilation rate depends on the level of sunlight to plants. The spread of solar radiation on the canopy determines the dry matter production rate per unit leaf area during vegetative growth.…”

Red spinach (Amaranthus tricolor L) is a horticultural vegetable that contains anthocyanins, protein, calcium, phosphorous, iron, vitamin A, vitamin C, and B vitamin. However, this plant has not become a major commodity, so it is generally grown in lands with a low level of soil fertility. Application of arbuscular mycorrhizal (AM) fungi in powder dosage form can help plant growth with a positive effect. However, this dosage form has several weaknesses, so a study aimed at knowing the effectiveness of AM fungi in different dosage forms is needed in physiological studies to analyze plant growth and the level of colonization of red spinach roots in the vegetative stage. This research was carried out using the model of the Latin square design (LSD) with three treatments for AM dosage forms of fungi: tablets, sachets, and powders, and without mycorrhizal application (control). The results showed that AM fungi in sachet dosage form could colonize the roots of spinach plants with the highest percentage, although physiological studies have not given consistent results. The sachet dosage form of AM fungi is the novelty of this study. AM fungi in a sachet dosage form can are recommended as the dosage form the most attractive, efficient, and effective to be applied and mobilized to farmers' fields.

“…Thus, NPPT+KP significantly increased chlorophyll content (Table 4), while the chlorophyll content was the determining index of yield increase (Fig. 2), which is in accordance with the previous study (Orzech et al 2022), and thus significantly increased yield. The NPPT+MP treatment accelerated the rate of NPPT degradation in the soil, increased the ammonia volatilization loss, then caused a significant decrease in yield, plant N uptake, and NUE (Table 5) (P < 0.05).…”

Urease inhibitors (UIs) and nitrification inhibitors (NIs) still have limitations in increasing crop yield. Therefore, to improve the application effect of inhibitors, the combination of seaweed extracts (SE) from different sources and inhibitors was added to urea to provide a theoretical basis for the development of a new generation of efficient stabilized urea fertilizer with both biostimulant and inhibitor technologies. The combinations were tested in outdoor pots with no N- fertilizer (CK), application of urea alone (U) as control, and kelp polysaccharide (KP), margin polysaccharide (MP), N−(n−propyl) thiophosphoric triamide (NPPT), dicyandiamide (DCD), and combinations of SE with inhibitor were added to urea to make eight fertilizer prototypes. Compared with KP, MP showed better application effect, with significantly higher grain yield and nitrogen use efficiency (NUE) (P < 0.05). Compared with the addition of inhibitor alone, the combinations of NPPT with KP and MP, respectively, had opposite effects on urea−N transformation, meanwhile NPPT+KP had a positive effect. However, NPPT+MP significantly decreased yield, plant nitrogen uptake, and NUE (P < 0.05); DCD+MP decreased plant N uptake and NUE to some extent. Therefore, the addition of NPPT with KP and DCD with KP to urea significantly improved yield when planting maize in black soil.

“…To overcome abiotic stress, plants induce the accumulation of proline [20] and soluble sugars [21] to safeguard cell membranes by managing intercellular osmotic pressure. Moreover, biomass production in plants is correlated with energy consumption and gas exchange, which in turn depend on net photosynthesis [22]. In view of the food security and sustainability of available water resources, Saudi Arabia is focusing on alternative irrigation resources for groundwater sources, such as desalinated water (i.e., saline water).…”

Tomato (Solanum lycopersicum L.) is an important vegetable crop that grows easily under controlled conditions, such as in greenhouses and hydroponics. To overcome freshwater scarcity, researchers are searching for alternatives to groundwater sources such as desalinated water (saline water) for irrigation. High salinity in irrigation water alters physiological functions and crop development, thereby reducing the yield. Best management practices and the use of grafted tomato plants on salt-tolerant rootstocks can alleviate salinity stress. The present study was conducted to address the impact of salinity stress on leaf transpiration (Tr), stomatal conductance (gs), photosynthesis (Pn), leaf chlorophyll content, proline content, and yield of hydroponically cultivated tomato plants. Saline (NaCl) water was used for the preparation of nutrient solution with three salinity levels, electrical conductivity (EC, dS m−1) of 2.5 (control), 6.0, and 9.5. Three commercial tomato cultivars (Valouro-RZ, Ghandora-F1, and Feisty-Red) were used. Both self-rooted plants and plants grafted onto Maxifort rootstocks were transplanted onto a perlite substrate. The recorded data revealed that all studied cultivars were critically affected by higher salinity (≈ 9.5 dS m-1) compared to low (≈ 2.5 dS m-1) and medium (≈ 6.0 dS m-1) salinity levels. The Variations in Tr, Pn, gs, chlorophyll content of leaf, and yield between medium and high salinity trials were reported at 3%, 5%, 9%, 5%, and 7.1%, respectively, whereas no significant differences were observed between low and medium salinities. However, at medium salinity levels, grafted plants performed better in photosynthesis than non-grafted plants. This is due to the accumulation of leaf proline, which maintains osmotic regulation and photosynthetic activity by preventing cell damage at medium salinities. Hence, this study confirmed the use of saline water for growing tomatoes under hydroponic conditions up to an EC of 6.0 dS m-1 including the EC of nutrient fertilizers.
