“…This result indicates the positive and most signi cant action of Si on the evaluated parameters of this cultivar. The ASF tested here has been shown to improve the water use e ciency for onions grown in a semiarid climate [32], which can be responsible for the better response to Si of grapes cultivated in the dry season. Besides, as water and heat stress commonly coincides, Si may have played a role in diminishing the damage caused by the high temperatures in the dry season.…”

Purpose: Silicon (Si) acts to reduce biotic and abiotic stresses in plants. Herein, we aimed to assess the impact of an amorphous silica-based fertilizer (ASF) applied to soil on the yield, mineral nutrition, chlorophyll uorescence, and postharvest quality of two cultivars of table grapes grown in a semiarid climate.Methods: The cultivars Arra 15 and BRS Vitoria were submitted to the treatments control, 175 or 350 kg ha -1 ASF.Leaf and fruit samples were collected and analyzed for Si, nutrients, and postharvest quality characteristics. Photosynthetic e ciency was assessed by measuring chlorophyll a uorescence .Results: Both cultivars showed signi cant responses to Si with the ASF rates of 175 and 350 kg ha -1 . The characteristics improved through ASF application compared to the control were: fruit production (6 -22 %), bunch weight (11 %), number of berries (20 -34 %), berry crunchiness (20 %), the content of total soluble solids (13 -20 %), the titratable acidity (13 %), the accumulation of macro and micronutrients (12 -45 %) and the photosynthetic e ciency (5 -33 %).Conclusions: Soil-applied Si increases the yield and quality of grapes by improving the plant response to abiotic stresses, being such effects more signi cant in the dry season.

“…For instance, some works have shown that Si increases the root hydraulic conductance and cell wall stability [52,53], imparting high tolerance to water de cit, besides increasing water uptake by roots [54]. In addition, silicon fertilization promoted onion plants' salt stress acclimation, resulting in improved bulbs yield in semiarid conditions [5].…”

“…Onions can be consumed as raw, fresh, or processed and contain antioxidants and anti-in ammatory compounds that reduce cholesterol levels, diabetes, high blood pressure, and the risk of cardiovascular diseases [1][2][3]. The global production of 98 Mt of onion makes it the second most important vegetable crop after tomato [4][5][6]. The crop is grown in different regions of Brazil and is the country's third most relevant vegetable crop, behind potatoes and tomatoes.…”

Purpose Silicon (Si) can reduce abiotic stresses in plants and increase crop yield in semiarid climates. We aimed to assess the effect of an amorphous silica-based fertilizer (ASF) applied to soil on the yield, mineral nutrition, and health of an onion crop grown in northeast Brazil. Methods The ASF was applied at the rates of 0, 75, 125, 175, and 225 kg ha− 1. Yield and quality of bulbs as well as leaf concentrations of Si and nutrients were evaluated. Stress amelioration was assessed through Normalized Difference Vegetation Index (NDVI). Results ASF increased the yield of onions and enhanced the concentration of Si, N, P, K, Ca, Mg, B, Mn, Zn, and Cu in leaves. There was no ASF effect on bulb quality. NDVI indicated that applying 225 kg ha− 1 ASF to soil promoted healthier onion plants and the highest yield. Conclusions Silicon increased the yield of onions due to improved plant nutrition and stress amelioration.

Field experiments were conducted to investigate an appropriate saline water management strategy to enhance the yield and irrigation water use efficiency (IWUE) of drip‐irrigated onion. The effects on soil water–salt dynamics, growth parameters, IWUE and yield were assessed under different lateral spacings and irrigation treatments. The different treatments comprised two lateral spacings (45 and 60 cm) and four irrigation treatments (canal water, C; conjunctive use of canal and saline water in a 1:1 ratio, C1S1; in a 1:2 ratio, C1S2; and saline water, S). The results show that soil moisture content decreased vertically downwards and radially outwards in all treatments, whereas soil salinity increased and decreased with increasing radial distance and soil depth, respectively, throughout the soil profile irrespective of the lateral spacing and irrigation treatments. The maximum yield and IWUE were observed at 45‐cm lateral spacing for treatment C, followed by C1S1, C1S2 and S. It was concluded that the C1S1 treatment can be employed successfully for onion cultivation in sandy loam soil without any significant reduction in yield. The present study highlights the significance of irrigation treatments and lateral spacing for maximum production, which may be used as a baseline/guideline to increase the income of onion growers/farmers in semi‐arid regions.
