“…Where, average fruit weight and flesh thickness of fruit were decreased by increasing deficit rates, and the opposite trend with regard to fruit firmness and TSS, which were increased by increasing deficit rates. These results are in agreement with those of Ibrahim (2012), Li et al (2012), and de Azevedo (2016). Most fruits quality parameters, i.e., fruit shape index, average fruit weight, flesh thickness of fruit, and fruit firmness, were significantly affected by the cvs.…”

“…The most important problems facing the horizontal expansion of cantaloupe in greenhouses or in open field are the water shortage, especially in the new reclaimed lands. Whereas, deficit irrigation had an opposite influence on production of fruits (Al-Mefleh et al 2012;de Azevedo 2016;Elvis et al 2017) and physical fruit quality expressed as weight, length, diameter average weight, and size are severely decreased (Zeng et al 2009;de Azevedo 2016 as well as on watermelon Ibrahim 2012 andElvis et al 2017). This leads the researcher to use some new trends to mitigate these negative impacts.…”

Background: Water use efficiency (WUE) is becoming a decisive factor for agricultural expansion to face water shortage. To meet the needs of high population density in Egypt, we have to use modern irrigation systems and new cultivation technologies. The current study is aiming to apply grafting technique for ameliorating the impact of deficit water on cantaloupe productivity and fruit quality. Two commercial cultivars (Ideal and Veleta) were grafted on two rootstocks (Cobalt and Strong-Tosa) and self-grafting. The seedlings were treated with three different irrigation levels: 100, 75, and 50% of Class A pan Evapotranspiration (ETc). Results: The results showed that moderate irrigation level (75% ETc) increased the early yield, fruits number, by 15.3 and 17.4%, respectively, compared to control irrigation treatment (100% ETc). No significant variation was found concerning total yield between 100 and 75% ETc, so this led to an increase in WUE of moderate irrigation level (75% ETc) by 34.3%, compared to control irrigation treatment (100% ETc). Increasing deficit levels up to 50% ETc reduced the total yield by 47.4%, but it increased the WUE by 8.8%, compared to the non-deficit irrigation level (100% ETc). Meanwhile, grafting both cultivars on Cobalt rootstock improved the fruit number, total yield, and WUE by 39.2%, 26.9%, and 24.1%, respectively when irrigated with the moderate irrigation level (75% ETc), as compared to the non-grafted plants which recorded the highest decrease when irrigated with deficit irrigation level (50% ETc). Conclusion: Finally, the combination treatments of Ideal/Strong-Tosa, Veleta/Cobalt, or Ideal/Cobalt irrigated with moderate irrigation level (75% ETc) increased the WUE by 97.3, 83.4, and 65%, respectively, compared to the control treatment (non-grafted plants of the same cv. at 100% ETc) and recorded higher flesh thickness, TSS and firmness.

“…Water-yield relationships:The crop response factor (Ky) is the coefficient used to indicate plant sensitivity to water stress at any stage of its cycle (De Azevedo et al, 2016). The Ky values lower than 1.0 indicate that the crop showed some adaptability to the water stress (de Carvalho et al, 2016).…”

Common bean (P. vulgaris L.) is the most important food legume in the diet of people and drought stress causes severe yield loss in this crop. This study was conducted to investigate morpho-physiological responses, yield and WUE of four common bean (P. vulgaris L.) cultivars (namely : “Sarýkýz”, “Sazova”, “Kýrk günlük”, and “Gina”) under different (I1.00: 100%-control of field capacity, I0.75: 75% of field capacity and I0.50: 50% of field capacity) water regimes. The investigation was conducted in a pots and experiments were carried out randomized plot design with ten replicates. The results of this investigation show that yield, yield components, LRWC, leaf area and chlorophyll contents were reduced, while WUE increase depending on the different water regimes in all cultivars. Consequently, cv. “Gina” may have the potential to be used in drought areas.

“…Silva et al (2019) mostraram que o manejo eficiente no uso da água favorece a convivência com o Semiárido e a mitigação dos efeitos que a alta variabilidade climática proporciona sobre as plantas cultivadas. Por sua vez, Azevedo et al (2016), ao estudarem a cultura do melão irrigado por gotejamento em uma área inserida no Semiárido do Brasil, verificaram que o déficit hídrico controlado pode ser uma alternativa para aumentar a eficiência no uso da água. Por sua vez, Mila et al (2017) constataram que a irrigação deficitária é uma técnica eficaz para regiões com escassez de água, os autores alcançaram a eficiência máxima no uso da água irrigando 60% do déficit da zona radicular em estágio vegetativo e pré-florado na cultura do girassol (variedade: BARI Surjomukhi-2) nas condições de clima semiárido de Bangladesh.…”

Em regiões suscetíveis a desertificação, como é o caso do Semiárido, o uso de tecnologias hídricas pode servir como ferramenta para mitigar os impactos ambientais, aumentar a eficiência no uso da água e garantir uma menor estacionalidade da produção. Nesta revisão, buscamos abordar as principais estratégias que podem contribuir para a sustentabilidade, intensificação e planejamento da atividade agrícola nas regiões com riscos de desertificação. Para isso, discutiu-se os problemas e as principais características ambientais das áreas suscetíveis a esse processo; abordou-se o uso de tecnologias hídricas (e.g. adoção de espécies vegetais resistentes ao estresse hídrico, uso de clones/cultivares mais adaptados à condições estressantes, intensidade de corte, cultivo, uso de cobertura morta), práticas que visam aumentar a eficiência do uso da água na agricultura; destacou-se o modelo AquaCrop da FAO como ferramenta para inferir sobre o impacto de possíveis cenários ambientais na agricultura, bem como simular as melhores estratégias de resiliência; e, por fim, frisou-se outros conceitos relacionados a sustentabilidade da agricultura como: eficiência no uso da água, agricultura verde, e caracterizadores de um sistema agrícola. Nossos achados reforçam a necessidade de uma visão holística dos agroecossistemas para integrar as tecnologias hídricas a outras estratégias de aumento da eficiência no uso dos recursos e de redução a liberação de gases de efeito estufa (GEE), de modo a contribuir com a sustentabilidade da atividade e a mitigação dos impactos no meio ambiente. Outrossim, com a utilização da modelagem é possível prever os impactos que as condições climáticas futura proporcionarão ao planeta, de modo a planejar estratégias mais eficazes para a convivência da agricultura com as mudanças do clima.Palavras-chave: AquaCrop; eficiência no uso da água; estratégias de resiliência agrícola. Water technologies and modeling: strategies in the search for sustainability and intensification of agriculture in susceptible environments to desertification A B S T R A C TIn regions susceptible to desertification, such as the semi-arid region, the use of water technologies can serve as tool to mitigate environmental impacts, increase water efficiency, and ensure a lower state of production. In this review, we seek to address the main strategies that can contribute to the sustainability, intensification and planning of agricultural activity in regions with desertification risks. To this end, the problems and main environmental characteristics of the areas susceptible to this process were discussed; the use of water technologies (e.g. adoption of plant species resistant to water stress, use of clones/cultivars more adapted to stressful conditions, cutting intensity, cultivation, use of mulch), practices aimed at increasing the efficiency of water use in agriculture; the FAO AquaCrop model was highlighted as a tool to infer about the impact of possible environmental scenarios on agriculture, as well as to simulate the best resilience strategies; and, finally, other concepts related to the sustainability of agriculture were emphasized, such as: efficiency in the use of water, green agriculture, and characterizations of an agricultural system. Our findings reinforce the need for a holistic view of agroecosystems to integrate water technologies with other strategies to increase resource efficiency and reduce the release of greenhouse gases (GHG), to contribute to the sustainability of the activity and the mitigation of impacts on the environment. Moreover, with the use of modeling it is possible to predict the impacts that future weather conditions will bring to the planet, to plan more effective strategies for the coexistence of agriculture with climate change.Keywords: AquaCrop; efficiency in water use; agricultural resilience strategies
