The climate change is already affecting many agricultural systems and human environments, the implementation of adaptation strategies, especially those related to irrigated agriculture in semiarid regions, urgent. In this regard, deep knowledge about effects that irrigation has on food quality parameters will allow us estimate potential benefits deficit (DI) strategies. This work presents three almond cultivars (Marta, Guara, Lauranne) subjected doses: (i) full-irrigated treatment (FI) at...

Deficit irrigation (DI) strategies are considered essential in many arid and semi-arid areas of Mediterranean countries for proper water management under drought conditions. This fact is even more necessary crops such as almond (Prunus dulcis Mill.), which the last recent years has been progressively introduced irrigated areas. An aspect to be would ability improve fruit-quality parameters when DI imposed, can boost final price ensure sustainability competitiveness this crop. work examines...

The Mediterranean region is one of the most water-scarce areas worldwide and considered a climate-change hotspot. To assure viability competitiveness irrigated agriculture, it vital to implement strategies that can maximize water saving without compromising yield. Deficit irrigation (DI) for cultivating drought-tolerant species such as almond (Prunus dulcis (Mill.) D.A. Webb) help in achieving this goal, while at same time improving fruit chemical composition. This work evaluated effect DI...

This work examines the long-term effects of deficit-irrigation (DI) practices in almond crop (Prunus dulcis Mill.) agronomical and physiological terms. The trial was conducted during four-year monitoring period (2014–2017), an experimental orchard (SW Spain), subjected to three irrigation regimes; i) a full-irrigation treatment (FI), which received 100% evapotranspiration (ETC); ii) regulated-deficit (RDI50), 50% ETC kernel-filling period; iii) low-frequency deficit (LFDI), that continuous...

Mango (Mangifera indica L.) is one of the most important fruit crops in tropical and subtropical regions worldwide. On coast Granada Malaga (SE Spain), irrigated species have been introduced cultivated on terraces with a considerable economic importance as only European production region. The this zone possible intensive irrigation terraces, which are economically more profitable than traditional rainfed (almond olive), replaced or abandoned. A 2-year monitoring period was conducted using...

This work examines the use of thermal imaging to determine crop water status in young almond trees under sustained deficit irrigation strategies (SDIs). The research was carried out during two seasons (2018–2019) three cultivars (Prunus dulcis Mill., cvs. Guara, Lauranne, and Marta) subjected treatments: a full treatment (FI) at 100% requirements (IR), SDIs that received 75% 65% IR, respectively. Crop monitoring done by measurements canopy temperature, leaf potential (Ψleaf), stomatal...

Almond (Prunus dulcis Mill. (D.A. Webb)) plantations in irrigated semi-arid areas need to successfully face the new scenarios of climate change combining sustainable irrigation strategies and tolerant cultivars water stress. This work examines response young almond (cvs. Guara, Marta, Lauranne) subjected different doses under conditions (South-West Spain). The trial was conducted during two seasons (2018–2019) with three strategies: A full-irrigated treatment (FI), which received 100%...

The hydraulic traits of plants, or the efficiency water transport throughout plant system, could help to anticipate impact climate change and improve crop productivity. However, mechanisms explaining role on photosynthesis thus, growth yield, are just beginning emerge. We conducted an experiment identify differences in patterns at leaf, root whole level among four wild olive genotypes determine whether may explain such through their effect photosynthesis. estimated relative rate (RGR), its...

Fruit growth is a biophysical process that depends mainly on the daily balance between vascular (xylem and phloem) transpiration flows. This work examines seasonal behaviour of apricot fruit as well their Seasonal patterns shoot growth, surface conductance dry matter accumulation, were monitored at regular times intervals during season “Farbela” “Ladycot” cultivars. In addition, courses leaf stem water potentials gas exchanges 66 109 DAFB. On cultivar “Farbela”, phloem, xylem, flow to from...

In recent years, the area dedicated to modern irrigated almond plantations has increased significantly in Spain. However, legal irrigation allocations are lower than maximum water requirements of crop most cases. Therefore, growers forced implement regulated deficit strategies on their farms, applying stress certain resistant phenological periods and avoiding it sensitive periods. Given need monitor status crop, especially stress, objective this work was evaluate sensitivity two UAV-based...

Water is the most limiting resource in many semi-arid areas of Mediterranean countries. Among strategies to improve water productivity, implementation deficit irrigation (DI) and introduction drought-tolerant crops irrigated (such as almond) are being widely studied. Recently, use biostimulants enhance crop tolerance drought under water-scarcity scenarios increasing. This work examines response three almond cultivars (‘Guara’, ‘Marta’, ‘Lauranne’) terms yield associated physiological...

One of the challenges that European agriculture will have to face be adapt conventional procedures new agricultural policies. In this way, organic farming more importance in coming years. most important crops worldwide is grapevine. The main objective research work focuses on physiological, agronomic, and enological characterization Pedro Ximénez with purpose knowing viability cultivation cultivar a warm climate zone. Two experimental plots were selected two different types management,...

Water scarcity in many semi-arid agricultural areas, particular for the Mediterranean basin, is promoting changes irrigated agriculture, with alternative strategies being introduced water-use optimization. The coast of Granada and Malaga (Southeast Spain) an economically important area subtropical fruit cultivation. This intensively agriculture characterized by requiring extra amounts water adoption sustainable practices to improve management. A two-season experiment was conducted assess (1)...

The Pedro Ximénez grape variety is one of the authorised varieties in Jerez-Xérès-Sherry DO, although it currently occupies only 1% region's total cultivated area. With intention promoting its cultivation, as well diversifying production a historic wine-growing area such Marco de Jerez (Spain), work being carried out through research project which both public and private entities are participating. This focuses, among other aspects, on organic cultivation this minor grapevine region,...

The global warming is increasing the variability of rainfall and temperature, peculiarly, in arid semiarid environments worlwide. Alterations precipitation patterns evapotranspiration these areas will provoke an augmentation water requirements for crops, therefore, a collapse resources systems contemplated. This work presents deficit irrigation as adaptation tool shortage reducing vulnerability woody-fruit crops Mediteraean area. In this context, almond (Prunus dulcis Mill.) pistachio...

Abstract There is a controversy regarding when it appropriate to apply the irrigation restriction in almond trees (Prunus dulcis Mill.) save water without penalizing yield. We hypothesized that knowing plants demand fewer photoassimilates would be good indicator of less sensitivity crop deficit. One parameter defines photosynthetic capacity triose phosphate utilization (TPU). Due its connection export sugars from leaves other sink organs, candidate for being such an indicator. The objective...
