“…Rural producers face difficulties in choosing commercial table grape cultivars, due to the large number of options available on the market. There are currently more than 20 table grape cultivars made available by private international genetic and breeding companies for licensed growers (closed source with patent) and by Embrapa (the public Brazilian Agricultural Research Corporation) through its grape breeding program «Grapes of Brazil» (Uvas do Brasil) (open source) (Leão, Nascimento, Moraes & de Souza, 2020).…”

The São Francisco Valley (Pernambuco-PE, Brazil) is of great importance for the local economy, since the region represents a large portion of Brazilian production and export of fresh grapes. Traditional methods of feasibility analysis involve only cost or productivity analyses, but for the grape growers there must be techniques and methods that assist decision making involving other criteria with characteristics of the grape. Yet, there is a noticeable lack of multi-criteria methods that assist the grower in making decisions for selection of commercial table grape cultivars for the feasibility analysis. Thus, the aim of the present study is to select table grape cultivars through multiple criteria, using a new method for eliciting scale constants: the Flexible and Interactive Tradeoff (FITradeoff), for the purpose of assisting a rural producer to expand production while minimizing inconsistencies in the decision-making process. With the assistance of a decision maker, the Decision Matrix and Consequence Table were constructed on Microsoft Excel® – composed by 11 criteria and 3 alternatives, all closed source grape cultivars (with patents). Then, the data were applied on the FITradeoff software for the ranking problematic. Thus, it was possible to arrive at a ranking of the best alternatives, where the cultivar Timpson (SNFL) (U2) was found to be the optimal solution proposed for the rural producer. The application of FITradeoff provided a satisfactory result with little time and effort spent, leading to a final suggestion for the decision maker. In addition, at the end of the process, it provided graphical visualization of the performance and dominance of each criterion selected, as well as a ranking of the grape cultivars through the Hasse Diagram, with the order of the best alternatives. Ordering the grape genotypes considering Multi-Criteria Decision Analysis methods is crucial to selection of commercial table grape cultivars. The method can be applied to other segments of agriculture that require multi-criteria evaluations.

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.

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 fluorescence, 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 efficiency was assessed by measuring chlorophyll a fluorescence . Results: Both cultivars showed significant 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 efficiency (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 significant in the dry season.
