“…The increase in Na + uptake induced under salinity stress generates an antagonistic effect on the absorption of other ions, with K + , Ca +2 , Mg +2 , and NO 3 − being particularly affected under these conditions (Yildirim et al, 2009). The sensitive RIL-66 showed a significant decrease of K + and Mg 2+ under salinity and salinity +heat, whereas RIL-76 only showed a slight decrease on K + concentration under salinity stress and Ca 2+ under the combination of salinity and heat (Wang et al, 2013;Gouiaa and Khoudi, 2015;Plaza et al, 2017).…”

The development of plant varieties with a better nitrogen use efficiency (NUE) is a means for modern agriculture to decrease environmental pollution due to an excess of nitrate and to maintain a sufficient net income. However, the optimum environmental conditions for agriculture will tend to be more adverse in the coming years, with increases in temperatures, water scarcity, and salinity being the most important productivity constrains for plants. NUE is inherently a complex trait, as each step, including N uptake, translocation, assimilation, and remobilization, is governed by multiple interacting genetic and environmental factors. In this study, two recombinant inbred lines (RIL-66 and RIL-76) from a cross between Solanum lycopersicum and Solanum pimpinellifoilum with different degree of tolerance to the combination of salinity and heat were subjected to a physiological, ionomic, amino acid profile, and gene expression study to better understand how nitrogen metabolism is affected in tolerant plants as compared to sensitive ones. The ionomics results showed a different profile between the two RILs, with K + and Mg 2+ being significantly lower in RIL-66 (low tolerant) as compared to RIL-76 (high tolerant) under salinity and heat combination. No differences were shown between the two RILs in N total content; however, N-NO 3 − was significantly higher in RIL-66, whereas N-N org was lower as compared to the other genotype, which could be correlated with its tolerance to the combination of salinity and heat. Total proteins and total amino acid concentration were significantly higher in RIL-76 as compared to the sensitive recombinant line under these conditions. Glutamate, but more importantly glutamine, was also highly synthesized and accumulated in RIL-76 under the combination of salinity and heat, which was in agreement with the upregulation of the nitrogen metabolism related transcripts studied (SlNR, SlNiR, SlGDH, SlGLT1, SlNRT1.2, SlAMT1, and SlAMT2). This study emphasized the importance of studying abiotic stress in combination and how recombinant material with different degrees of tolerance can be

“…The horticultural crop selected was Cucumis melo and the ornamental crop was Rosmarinus officinalis because both crops coincide in the crop cycle and as a consequence the drainage generated by the horticultural crop can be used to irrigate the ornamental crop. Although there are references about these fertigation techniques in a sequential production (Citrullus lanatus and Cordyline fruticosa) [15,16], very little is known about the establishment of these techniques in other horticultural-ornamental crop systems. Therefore, in this study, a pot experiment with C. melo and R. officinalis was established in order to study the effects of different water treatments on plant growth, water saving and nutrient removal.…”

Abstract:The blending of drainage with water of low electrical conductivity and the sequential reuse of the drainage water are innovative technologies to manage salts in agricultural drainage. Plants of Cucumis melo were grown in coir grow bags, and Rosmarinus officinalis and Cacti spp. were grown in pots with a mixture of sphagnum peat-moss and perlite. In order to assess the effect and evolution over time of these water treatments on plant growth and water management and removal of nutrients, three water treatments were applied over a period of eight weeks. These were: (1) standard nutrient solution; (2) blended water treatment (drainage water blended with water of low electrical conductivity (EC)) and (3) sequential reuse of drainage water treatment. During the experimental growing period, samples of water supplies and drainages generated in each water treatment were collected weekly and from these data water volume and nutrient loads were calculated. At the end of the experiment, leaf fresh weight of rosemary plants decreased under the fertigation with the blended and sequential reuse water treatments. Nevertheless, the application of blended and sequentially reused water allowed for the saving of significant amounts of water and nutrients in comparison to the standard nutrient solution treatment. Considering these advantages, we strongly recommend the setting-up of these water treatments in areas with water scarcity such as in the Mediterranean Basin.

“…For instance, Lao and Jimenez [40] reported 46% and 58% of water and NO 3 − , respectively, leached in a tomato greenhouse crop (246 DAT) grown with traditional management in a mulched sandy soil (Table 6). Also, Plaza et al [46,47] reported 34% and 39% of water and NO 3 − , respectively, leached with watermelon grown in rockwool (80 DAT), and Garcia-Caparros et al [48] reported 28% and 17% of water and NO 3 − , respectively, leached with melon grown in perlite (91 DAT) ( Table 7).…”

Integral Management of Irrigation Water in Intensive Horticultural Systems of Almería

Abstract:The development of intensive horticulture in Almería, with a huge increase in greenhouse surface area, is related to three essential factors: climatic characteristics, groundwater use and mulching sandy soil. The purpose of the present paper is to draw a picture of the integral management of water irrigation in the intensive horticultural systems in the region, by identifying the most significant water resource contributions and alternative water resources. Results indicate that the use of groundwater for the irrigation of horticultural crops in the greenhouses presents a high degree of overexploitation of the aquifers, but due to the continuous search for alternative water resources, such as desalinated and reclaimed water, as well as in-depth knowledge of the integral management of water irrigation through automated fertigation and localized irrigation systems, the current status of the water resources could be sustainable. Moreover, being conscious of the pollution generated by agricultural leachates, the horticultural system of Almería is implementing complementary sustainable systems such as recirculation, cascade cropping systems and phytodepuration for the reuse of the leachate. Considering all these factors, it can be concluded that the intensive horticultural system is on the right path towards respecting the environment and being sustainable in terms of water use.
