“…Plant leaves showed mean values of 60.08 and 1.72 cm for LL and LW, respectively, and 7.91 for TNL, corroborating the literature, for conventional and organic onion planting (BETTONI et al, 2013;SILVA et al, 2021;YOLDAS et al, 2011).…”

“…The observed average of BM (146.24 g per bulb) is 14% higher than those found in the literature (Simon et al, 2014;Weingartner et al, 2018;Resende, 2019). This result was expected, since onion bulbs show positive responses to phosphorus fertilization, reaching a greater bulb diameter and productivity (Antoniadis et al, 2017;Silva et al, 2021;Weingartner et al, 2018).…”

“…The P is considered an essential nutrient in onion cultivation because it participates in the processes of photosynthesis, respiration, protein synthesis, cell multiplication and differentiation, and it is a nutrient with significant action in the formation and quality of the bulb (Resende et al, 2016). Phosphate fertilization is directly related to bulb size and consequently to onion productivity (Kurtz et al, 2018;Yuri, 2016;Silva et al, 2021). However, P deposits are finite and the sustainable management of this nutrient must be better studied.…”

Organomineral fertilizers is an innovation in agriculture, since it uses organic matter enriched with minerals. The combination of mineral phosphate and organomineral fertilization can contribute to the development of a more sustainable and economical fertilization program for the crop. So, organomineral fertilization can be an alternative or complement to mineral fertilization. However, the careful selection of fertilizer sources and doses is essential to increase productivity in the onion crop and finding proportions between different fertilizers can be a promising choice for sustainable agriculture. The aim of the present research was to evaluate the effect of different proportions of mineral and organomineral fertilizers on the development, production and post-harvest quality of onion bulbs, cv. Sublime F1, under Cerrado conditions. The experiment was carried out in the field, in Cristalina, GO, Brazil, in a randomized block design, with four replications. Six treatments were used: five proportions of mineral fertilizer (M) with organomineral (OM) and the control (without additional fertilization). It was evaluated: length, width and number of leaves; productivity; soluble solids content; titratable acidity; and loss of fresh mass. Data were submitted to analysis of variance (ANOVA), at 1% (p≤0.01) and 5% (p≤0.05) of significance, and means compared by Tukey and Dunnett tests (p≤0.01 and p≤0.05). The fertilization proportions were submitted to regression (p≤0.05). The proportion of 50%M50%OM promotes higher bulb average mass and class 4 onion productivity. The proportions of fertilizers did not alter the postharvest characteristics (total soluble solids and total acidity) of the onion, which were affected only by the time of storage. Cultivar Sublime F1 showed good development for the region, conditions and fertilizers used.

“…Before raising the beds, the soil was plowed and harrowed. Planting fertilization was carried out with 190 kg ha -1 of P 2 O 5 (Silva et al, 2021) as single superphosphate. Top-dressing fertilization was applied split and applied via fertigation, using 74.0 kg ha -1 of N, 204.0 kg ha -1 of K 2 O (Gonçalves, 2019a; O.M.-Organic matter; H+Al-Potential acidity; SB-Sum of bases; CEC-Cation exchange capacity; V-Base saturation Table 1.…”

The common climatic characteristics in semi-arid regions can cause abiotic stress and be a limiting factor for crops. Under these conditions, the use of beneficial elements such as selenium (Se) is an alternative to mitigate the harmful effects of abiotic stresses and increase yield. Therefore, this research aimed to evaluate the agronomic performance of onion grown in a semi-arid region under the application of Se. A field experiment was performed in a randomized block design, where five doses of Se (0, 15, 30, 45, and 60 g ha-1), by foliar application, were tested on two onion hybrids (Andrômeda and Rio das Antas). Growth, nutritional and yield variables were analyzed. Se increased the height and accumulation of dry mass in onion plants, with a maximum at the 60 g ha-1 dose of Se, the same dose at which the highest commercial (78.15 t ha-1) and total (86.03 t ha-1) bulb yields were obtained in Rio das Antas; however, for Andrômeda, there was no effect of Se on yield. Applied Se doses also increased the content of this element in the bulbs. Despite increasing bulb yields only in the Rio das Antas hybrid, 60 g ha-1 of Se is recommended for onions due to its effects on plant growth and the biofortification of bulbs with Se.
