“…The SMS-treated plots had significantly higher soil-water tension values at 6-inch depths in June and July 2016 compared with the VegApptreated plots but there were no differences between the two treatments at 10-or 14-inch depths for the same time period. This may be because of the relatively shallow placement of the porous tip of the tensiometers (6-8 inches deep), which could result in increasing demand for water at shallower depths compared with the VegApp (Marouelli and Silva, 2007;Marouelli et al, 2004).…”

A new smartphone vegetable irrigation scheduling application (VegApp) was compared with current irrigation scheduling recommendations and soil moisture sensor (SMS)–based irrigation for growing tomato (Solanum lycopersicum) in southern Georgia during Spring 2016 and 2017. Plants were grown using plastic mulch and drip irrigation following standard production. The VegApp-scheduled irrigation based on crop evapotranspiration (ETc) values calculated daily from meteorological data retrieved from nearby weather stations, whereas ETc rates for current water balance (WB)–based recommendations were calculated from historic averages for the region. Water usage, soil moisture tension, fruit yield and quality, and foliar macronutrient content were measured. In 2016, plants grown using SMS-based irrigation applied the least water followed by the VegApp- and WB-grown plants. In 2017, WB-treated plants received the least water, followed by VegApp- and SMS-grown plants. Total marketable yields were similar among treatments and years. Irrigation water use efficiency (IWUE) varied between year and irrigation regime, with SMS-grown plants having a significantly greater IWUE than the other treatments in 2016. Plants irrigated using the VegApp had a greater IWUE than SMS-irrigated plants in 2017. Differences in IWUE were largely the result of variable irrigation volumes and not changes in yield. Fruit total soluble solids (TSS) were unaffected by treatment in either study year. Fruit pH was affected by irrigation treatment in 2017. Foliar nitrogen concentrations were affected by irrigation regime in 2017, with VegApp-grown plants having significantly greater concentrations of foliar N than other irrigation treatments. The results of this study suggest that the VegApp could be a reliable tool that can be used by growers to produce yields comparable to currently accepted irrigation scheduling practices and reduce water use in some seasons.

“…A lâmina de água aplicada por irrigação, medida por coletores de 1.500 mL, posicionados em cada subparcela, foi a suficiente para elevar a umidade do solo à capacidade de campo (6 kPa), na camada correspondente à profundidade efetiva do sistema radicular. As irrigações foram paralisadas quando 50% dos frutos atingiram a maturação (Marouelli et al, 2004).…”

Resumo -O objetivo deste trabalho foi avaliar o efeito da quantidade de palhada sobre o solo (3, 6 e 9 t ha -1 de matéria seca de sorgo forrageiro), em sistema de plantio direto (SPD), sobre o uso de água e variáveis relativas à produção de cultivares de tomate para processamento, tendo como controle o sistema de plantio convencional (SPC). O delineamento experimental foi o de blocos ao acaso, com parcelas subdivididas e quatro repetições. Foram avaliadas as cultivares H9553 e H9992, em 2003, e H7155 e U2006, em 2004. A economia de água nos tratamentos de SPD, até 50 dias após o transplante das mudas, foi de 25%, comparado ao SPC, e de 11% durante todo o ciclo. A resposta relativa das cultivares foi similar para as variáveis avaliadas. A produtividade de frutos foi maximizada na quantidade de palhada de 6 t ha -1 , e a taxa de frutos podres minimizada para 5,2 t ha -1. A produtividade no SPC foi de 10 a 17% menor do que nos tratamentos de SPD. A eficiência do uso de água pelas plantas não foi afetada pela quantidade de palhada, porém, o SPD foi 23% mais eficiente que o SPC.Termos para indexação: Lycopersicon esculentum, cultivo mínimo, plantio na palha, eficiência do uso de água, irrigação. Water use and production of processing tomato under no-tillage system and straw mulching conditionsAbstract -The work aimed to evaluate the effect of straw rates (3, 6, and 9 t ha -1 dry matter of sorghum forage), under no-tillage system, on crop water use and production of four processing tomatoes cultivars, as compared to conventional tillage system. The experimental design was the randomized blocks design with split plots and four replicates. Cultivars H9553 and H9992, in 2003, and H7155 and U2006, in 2004, were evaluated. The water use under no-tillage treatments during the first 50 days, since seedlings were transplanted, was 25% lower as compared to conventional tillage, and 11% lower during the entire crop season. Cultivars relative performance was equivalent for all evaluated variables. Marketable fruit yield was maximized at 6 t ha -1 straw, while rotten rate fruit was minimized at 5.2 t ha -1 . Under conventional tillage system, fruit yield was 10 to 17% lower than under no-tillage treatments. Crop water use efficiency was not affected by cover crop rates, but no-tillage treatments yielded an average water use efficiency 23% higher than conventional tillage system.

“…DI, in fact, can be used both to save water and also to improve the quality of some products; nevertheless, special attention must be given when stress was induced, because the water deficit in sensitive phenological phases (such as flowering) can reduce the content of sugars, acids, and carotenoids (Ripoll et al, 2016). Different authors observed how DI increased the content of lycopene, vitamin C, and β-carotene (Favati et al, 2009; Patanè and Cosentino, 2010; Patanè et al, 2011; Chen et al, 2013), regardless of dependence on period and the degree of water stress (Pulupol et al, 1996; Nuruddin et al, 2003; Marouelli et al, 2004; Favati et al, 2009). DI could, therefore, be considered a useful tool to increase in tomato fruits the content of these nutrients (Juroszek et al, 2009), although it reduces the yield (Nuruddin et al, 2003; Marouelli et al, 2004).…”

Effect of Preharvest Abiotic Stresses on the Accumulation of Bioactive Compounds in Horticultural Produce

The quality of horticultural products is the result of the interaction of different factors, including grower’s crop management ability, genotype, and environment. Sub-optimal environmental conditions during plant growth can induce abiotic stresses and reduce the crop performance with yield reduction and quality losses. However, abiotic stresses can induce several physiological, biochemical, and molecular responses in plants, aiming to cope with the stressful conditions. It is well known that these abiotic stresses are also elicitors of the biosynthesis of many metabolites in plants, including a wide range of bioactive compounds, which firstly serve as functional molecules for crop adaptation, but they have also a great interest for their beneficial effects on human health. Nowadays, the consumer is oriented to low-energy foods with low fat content, but at the same time, growing attention is paid to the presence of bioactive molecules, which are recognized as health-related compounds and concur to the nutraceutical value of plant-derived foods. In this context, fruit and vegetables play an important role as sources of bioactive ingredients in the diet. At the cultivation level, the understanding of crop responses to abiotic stresses and how they act in the biosynthesis/accumulation of these bioactive compounds is crucial. In fact, controlled abiotic stresses can be used as tools for improving the nutraceutical value of fruit and vegetables. This review focuses on the quality of vegetables and fruits as affected by preharvest abiotic stressors, with particular attention to the effect on the nutraceutical aspects.
