Strawberry fruit quality traits can be affected by genotype–environment interactions, determining the final consumer acceptance of fruits. Trait stability under varying environments is necessary to ensure strawberries selected breeding programs. Hence, inter- and intra-annual variation organoleptic functional parameters five strawberry varieties throughout four consecutive cropping seasons was analyzed assess their relative stability. In most varieties, showed higher inter-annual but greater...

The growth of the global population, together with climate change and water scarcity, has made shift towards efficient sustainable agriculture increasingly important. Undoubtedly, recent development low-cost IoT-based sensors actuators offers great opportunities in this direction since these devices can be easily deployed to implement advanced monitoring irrigation control techniques at a farm scale, saving energy decreasing costs. This paper proposes an economic periodic predictive...

Strawberry (Fragaria×ananassa Duch.) production requires the input of large amounts water provided by irrigation during entire cycle. However, availability is shrinking in many important strawberry cropping areas, such as Huelva (in Europe), compromising environmental sustainability and economic viability production. Besides technical approaches, water-saving strategies are necessary for improving productivity use low water-consumptive cultivars with high or allowing deficit (DI) strategies....

Four rectangular sluice gates were calibrated for submerged-flow conditions using nearly 16,000 field-measured data points on Canal B of the B-XII irrigation scheme in Lebrija, Spain. Water depth and gate opening values measured acoustic sensors at each structures, recorded electronic loggers. Several calibration equations tested it was found that can be used accurate flow measurement. The Energy-Momentum (E-M) proved to sound. contraction coefficient, energy equation, allowed good...

Developing an appropriate irrigation schedule is essential in order to save water while at the same time maintaining high crop yields. The standard procedures of field evaluation distribution uniformity do not take into account effects filling and emptying phases system. We hypothesized that, sloping sandy soils, when short drip pulses are applied it important total from beginning until To compute uniformity, we sought characterize filling, stable pressure, a strawberry found that shorter...

The experiment evaluates the food production and water treatment of TAN, NO2−–N, NO3−–N, PO43− in two aquaponics systems using dynamic root floating technique (DRF). A separate recirculation aquaculture system (RAS) was used as a control. fish cultured Nile tilapia (Oreochromis niloticus). hydroponic culture one (PAK) pak choy (Brassica chinensis,) other (COR) coriander (Coriandrum sativum). Initial final weights were determined for culture. Final edible fresh weight plant measured once week...

Berry crops have transformed the province of Huelva, in Southwest Spain, transforming it into a prosperous area Andalusia. Since 1990 s, there has been debate this about balancing agricultural production with environmental preservation, because 75% berry is vicinity Doñana National Park, natural high ecological value designated as World Heritage by UNESCO. Therefore, necessary to improve efficiency water use area. The advancement mobile devices allowed their wide technicians and farmers...

In Bogotá, as in most large Latin American cities, urban informality is a persistent phenomenon. Although the expansion of new informal land has decreased, densification existing settlements one mechanisms driving persistence informality. While lot known about factors that triggered American, less recent processes production cities and role process. We analyze build-up area 2007 2018 formal zones. Information was reduced through principal components analysis, we evaluated with linear...

There is renewed interest in developing calibration methods for gates operating submerged conditions irrigation canals. In the present study, a new method based on generalization of standard energy-momentum that accounts variations energy and momentum velocity coefficients proposed, following reasons. First, it was found assumption uniform jet to account kinetic head flux reality equivalent assuming parabolic relationship between Coriolis Boussinesq coefficients. Second, literature...

Greenhouse horticultural crops are characterized by high levels of efficiency and productivity irrigation water nutrients applied. However, these indices may be affected poor distribution uniformity fertigation (DU). Different previous prospective studies show that there is a significant percentage facilities with low level DU. no precise relationship between DU the fertilizers. This different factors, especially dose. The objective this work was to determine effect volume (FV) on bio...

The high productivity and efficiency of the use irrigation water that characterizes greenhouse horticultural crops can be affected by poor distribution uniformity. objective this work was to estimate average uniformity (DU) greenhouses in Almería, determining influence quality as well production system on A prospective study carried out which commercial farms were selected used different qualities (groundwater vs. reclaimed) with systems (organic conventional/integrated). Almería 80%....

Abstract Measuring water flow is essential for sound irrigation management. New commercial flowmeters based on acoustic technology have become popular measuring discharge in open channels of schemes Spain and various other countries.
