Актуальність проблеми. У статті представлені дані дослідження функціонального стану рівноваги дітей 10 років із депривацією зору. У дітей із депривацією зору, за даними сучасних наукових досліджень, спостерігається тенденція до збільшення проявів порушення координації рухів та наявність патологічних рухових моделей та стереотипів, що супроводжуються і труднощами візуального орієнтування у просторі. Мета роботи – аналіз стану функціональної рівноваги дітей 10 років із депривацією зору. У науковому дослідженні взяли участь 14 дітей 10 років із депривацією зору різного ступеня прояву. Дослідження проводилось на базі НРЦ «Зоресвіт» м. Одеси. Для реалізації поставленої мети дослідження були застосовані такі методи: теоретичні (аналіз наукової й методичної літератури, теоретичний аналіз та узагальнення, системний аналіз), педагогічні (експеримент, тестування), математичні. Для виявлення порушень балансу під час функціональної діяльності та планування необхідних розвивальних заходів для розвитку рівноваги та рухливості досліджуваних було використано шкалу балансу Берга. Результати, отримані за шкалою, порівнювалися з тестовими нормами, що дало можливість виявити рівень функціонального стану рівноваги дітей 10 років із депривацією зору. Дослідження загальних особливостей фізичного розвитку дітей реалізовувалось з використанням первинних методів математичної обробки: для опису стану рівноваги застосовано методи оцінки центральної тенденції (середнього арифметичного значення, моди розподілу) та варіативності розподілу (стандартного відхилення, квартилів розподілу). Вторинні методи математичної статистики: для підготовки даних до застосування статистичних процедур, зокрема для вибору адекватних статистичних критеріїв використано процедуру перевірки результатів дослідження на нормальність за допомогою критеріїв узгодженості Колмогорова–Смирнова з виправленням Лілієфорса та Шапіро–Уїлка. Статистичне опрацювання результатів дослідження відбувалося за допомогою використання програмного забезпечення IBM SPSS Statistics 21, графічний матеріал підготований у пакеті Microsoft Excel. Результати. Результати дослідження показали, що значення загального показника балансу розташовані в діапазоні від 44 до 51 балу із середнім значенням у точці 48,2 бала та стандартним відхиленням – 2,29 бала (48,2±2,29), а отже, у досліджуваній виборці є такі, хто має порушення балансу у разі функціональної діяльності (7,14%) та потребують певних розвивальних заходів, які забезпечують рівновагу. Висновки. Більшість досліджуваних здатні підтримувати рівновагу. Найкращим чином це стосується випадків стояння, сидіння, ходьби на місці, усаджування та переміщення з незначною допомогою рук. Лише дехто має певний ризик падіння у таких випадках. Найгіршим чином ці діти були спроможні стояти на одній нозі та виконувати стійку на двох ногах, одна попереду іншої.

На сучасному етапі в Україні особливо гостро постає питання поліпшення рівня здоров’я, фізичної та функціональної підготовленості студентів на заняттях із фізичного виховання. Масштабність цієї проблеми підтверджується результатами наукових досліджень, згідно з якими у вищих навчальних закладах неухильно збільшується кількість студентів підготовчих і спеціальних медичних груп, що свідчить про тенденцію до погіршення здоров’я випускників. Застосування кондиційного плавання на заняттях із фізичного виховання диктує необхідність врахування функціонального стану дихальної системи до плавального навантаження кондиційного спрямування, водночас на сьогодні майже відсутні публікації, які стосуються саме кондиційного плавання у студентів. Мета – визначити роль кондиційного плавання в підвищенні функціональних можливостей системи зовнішнього дихання студентів підготовчої групи. Методи дослідження. У роботі були застосовані методи теоретичного рівня дослідження: аналіз, порівняння, індукція, дедукція, систематизація та узагальнення науково-методичної літератури. Результати. У межах проблеми поліпшення рівня здоров’я студентів підготовчої групи особливо актуалізуються питання підвищення ефективності їхнього фізичного виховання, у якому плавання відіграє важливу роль, зокрема кондиційне плавання. Заняття кондиційним плаванням здатні скорегувати та покращити рівень рухової та функціональної підготовленості студентів, зокрема поліпшити вплив на функціональний стан системи зовнішнього дихання. Висновки. Результати проведеного дослідження свідчать про те, що низькі показники фізичного розвитку, фізичної підготовленості та функціонального стану системи зовнішнього дихання у студентів підготовчої групи детермінують необхідність систематичних і правильно організованих занять кондиційним плаванням. Сприятливий вплив таких занять можливий лише за умови відповідності застосовуваних засобів і методів індивідуальним особливостям функції зовнішнього дихання студентів та рівню їхньої фізичної підготовленості.

La propiedad intelectual como herramienta estratégica de protección y valorización del diseño industrial. Propuesta de curso inductivo al tema de la propiedad intelectual para alumnos de diseño industrial
Authors:   , Lara Vergara Fernanda Virginia
Published: November 2023

El tema de propiedad intelectual suele ser controversial e interesante para diversas disciplinas, incluyendo aquellas que tienen que ver con la creatividad y solución de problemas como es el caso del diseño. Esto se refleja en las dudas y confusiones existentes en los profesionistas y diseñadores en formación, quienes suelen tener un conocimiento limitado o nulo sobre el tema, que se ven involucrados en controversias o dificultades legales con respecto a la propiedad, originalidad y explotación de sus creaciones. No obstante, aunque el interés en la PI existe en muchas ramas del diseño, el presente trabajo aborda el tema de PI desde la disciplina del diseño industrial. Este documento proyecta el resultado de una investigación cualitativa, desde una perspectiva pragmática y subjetivista. La cual ha consistido en recabar información documental, así como la realización de entrevistas con especialistas y usuarios experimentados en el tema. La obtención de esta información a su vez, ha permitido proponer un estudio de caso, en el cual se analiza la integración del tema de propiedad intelectual, y el ejercicio de protección de esta, dentro del plan de estudios de la licenciatura en diseño industrial de la Universidad Autónoma Metropolitana Unidad Azcapotzalco, presentado al Colegio Académico en su sesión 480. En este trabajo se integran conocimientos de campos ajenos al diseño como los que conciernen al jurídico-legal, al económico y al social. Con esto se busca que, a partir de conocimientos adquiridos e integrados durante este proceso de investigación, genere un interés en la pertinencia de la PI y la protección de sus creaciones durante la formación y praxis de los estudiantes de la licenciatura mencionada.

Published: November 2023

The effects of foliar spraying of salicylic acid and proline on Echinacea purpurea under different soil moistures were investigated in the field conditions in the Southwest of Iran (2017–2019). The experiment treatments were the foliar application of salicylic acid (SA) and proline (both at 1 mM concentration) and 2 irrigation frequencies (6 and 10 every day based on 75–80% and 40–45% field capacity, respectively). The field experiment was set as a complete randomized block design with 3 replications. The volatile oils were analyzed using GC-FID and GC-MS. Germacrene D, p-cymene, β-caryophyllene, α-pinene, and β-bisabolene were detected as the main constituents. Deficit irrigation decreased the growth parameters of the plants; however, it improved the contents of the volatile oil and the major compounds of volatile oil. In addition, the maximum values of the volatile oil content and the main constituents of volatile oil were extracted from the plants under SA × water deficit treatment. In conclusion, the foliar spraying of SA under water deficit conditions was an applicable strategy to maintain and stabilize the growth and yield of E. purpurea.
Monitoring of basic physicochemical parameters in the flow and their possible influence on the quality of the small water source
Authors: Oppeltová Petra , Boráková Jana
Published: November 2023

The ground source of drinking water for the village of Skalice nad Svitavou is located 35 km North of Brno (Czech Republic). An evaluation of developments in selected indicators of water quality in this groundwater source in the period 2013–2017 was the essence of this work. The data was provided by Vodárenská akciová společnost, a.s., i.e. the operator. At the same time, annual monitoring of water quality in the Úmoří stream, which flows through the catchment area and can affect the quality of groundwater, was carried out. Water samples were collected in 2017–2018 from 6 profiles on the Úmoří stream and its two tributaries. Raw water from the groundwater source does not meet the requirements for drinking water in some indicators and needs to be treated. Monitoring of surface water shows that the most problematic indicator is total phosphorus, the concentration of which exceeded limit values on all sampling profiles. The highest values were found in the tributaries, where total phosphorus concentrations exceeded 10 mg∙dm–3. There are 12 municipalities in the area of interest, only two of which have their own sewage treatment plant. It is clear from the results that wastewater in some municipalities is discharged directly into the recipient and is the cause of above-limit concentrations of both phosphorus and nitrogen. Intensively used agricultural land is another major source of pollution. Based on an analysis of sources of pollution, corrective measures have been proposed to improve the quality of surface and groundwater in the area.

Published: November 2023

Tropical regions such as Java, Indonesia, still lack publication of soil water retention (SWR) information, particularly at upper Citarum watershed. The SWR is one of the critical elements in water storage and movement in the soil and very important to solve ecological and environmental problems. However, getting the access requires a lot of laboratory meas-urement that is time-consuming and expensive. Therefore, utilizing pedotransfer functions (PTFs) to estimate the water in the soil is needed. This study aims to define soil properties related to the SWR and to evaluate the performance of existing PTFs in predicting SWR. The study was carried out at agroforestry land system soil at upper Citarum watershed, Indonesia. Ten point and two continuous existing PTFs developed for tropical regions were applied in this study. Pearson's correlation (r), mean error (ME), root mean square error (RMSE), and modelling efficiency (EF) were used for evaluation. Cation exchange capacity (CEC), organic carbon (OC), bulk density (BD), and clay were considered as potential soil properties for soil water retention prediction. The performance of PTFs by MINASNY, HARTEMINK [2011] at matric potential of –10 kPaand BOTULA [2013] at matric potential of –33 kPa and –1500 kPa were recommended for point PTFs, while PTFs by HODNETT, TOMASELLA [2002] was for continuous PTFs in predicting SWR. The accuracy of the point PTFs is almost better than the continuous PTFs in predicting SWR in agroforestry land system soil at upper Citarum watershed, Indonesia.

Authors: Ożóg Karol
Published: November 2023

The Land and Property Register (LPR) also called the Cadastre by the legislator should function in accordance with regulations in force, meet expectations of the public and provide universal access to Register data for its users. Beyond any doubt, credibility and usefulness of data in this public register are affected by the manner it is kept, which generally in-cludes active and passive approach. If the LPR is kept in an active manner and constantly up to date, its data is very useful. The qualitative aspect of the land and buildings database’s records establishes the calculation accuracy of the owners’ land parcels evidenced in the Land and Mortgage Registers, which protect the ownership right to the property. In order to ensure that the plot of land is unequivocally and correctly measured, it is necessary to establish breakpoints of the parcels’ bounda-ries in the presence of the interested parties. Research conducted on the possibility of using the unmanned aerial vehicle (UAV) for measuring purposes indicates immense probability where this technology may be used for the selected details of group I (most accurately located) in modernization of land and buildings registers.

Published: November 2023

The paper presents results from social research on the Polish business representatives potentially interested in using the floating buildings. The main purposes of the study were to assess the level of knowledge about floating buildings and diag-nose stimulants and inhibitors of their development in the hotel, catering, and water tourism industry. Combining the quantitative and the qualitative methodology, research was conducted using an on-line survey (CAWI)and Focused Group Interviews (FGI). Both involved a non-probabilistic, purposive sampling to reach a specific subgroup of the industry: owners or employees of catering, hotel or water tourism companies having or considering having a floating building. The group included both new and long-standing companies using facilities on water or with direct and indirect access to the water. The study identified stimulating and inhibitory factors broken down into internal (context-independent) and external (context-dependent) conditions. Results show that in Poland floating commercial buildings are a niche topic but also a de-velopable one. Although 71% of the respondents notice difficulties resulting from the insufficient infrastructure and 66.5% of them indicate the lack of legal regulations, they also see the potential of floating buildings: depending on the industry, from 90 to 95% respondents find them “definitely attractive” or “rather attractive”. The most common reason for rejecting floating development is the lack of attractive moorages in the area (43.5% answers).

Published: November 2023

Improving water productivity (WP) through deficit irrigation is crucial in water-scarce areas. To practice deficit irriga-tion, the optimum level of water deficit that maximizes WP must be investigated. In this study, a field experiment was con-ducted to examine WP of the three treatments at available soil water depletion percentage (����) of 25% (reference), 45% and 65% using a drip irrigation system. Treatments were arranged in a randomized complete block design. The water deficit was allowed throughout the growth stages after transplanting except for the first 15 days of equal amounts of irrigations during the initial growth stage and 20 days enough spring season rainfall during bulb enlargement periods. Physical WP in terms of water use efficiency (WUEf) for treatments T1, T2, and T3 was 9.44 kg∙m–3, 11 kg∙m–3and 10.6 kg∙m–3 for mar-ketable yields. The WUEf and economic water productivity were significantly improved by T2 and T3. The WUEf differ-ence between T2 and T3 was insignificant. However, T2 can be selected as an optimal irrigation level. Hence, deficit irriga-tion scheduling is an important approach for maximizing WP in areas where water is the main constraint for crop produc-tion. The planting dates should be scheduled such that the peak water requirement periods coincide with the rainy system.

Published: November 2023

Flood risk management are considerably influenced by several factors, such as all sources of flooding, social circum-stances, policy and even the potential for local economic growth. To encourage government, business, community and oth-er parties to continue investing in flood risk management projects, it is necessary to give understanding that the projects can also provide economic benefits through systematic predictions and assessments of costs, benefits and social values, espe-cially on flood-affected communities. This study aims: (1) to develop knowledge and understanding on small-scale flood risk management project in Malang City, Indonesia, and; (2) to assess the economic efficiency of the project investment considering all benefits, both monetary and non-monetary. The research method is a mixed method combining quantitative questionnaires (N = 53 from 162 families) with qualitative in-depth interviews (N = 10) and field observations. The runoff discharge and the inundation depth were calculated using hydrology and hydraulic analysis, while the economic efficiency was analysed using cost benefit analysis (CBA). The results show that the community-based flood risk management system can reduce the flood risk up to 30% compared to before the implementation of that system. This system also provides direct financial benefits through the use of drainage channels for fish and vegetables farming. It causes the increase of the net so-cial benefit about 70–90% and the net present value (NPV) greater than zero (NPV > 0). Therefore, the project investment is recommended to be proceeded.

Published: November 2023

The analysis of ecological hazards on soil pollution by oil products has been provided in the impact zone of the railway. The results of oil product migration in soils in the area of influence on section Lviv–Khodoriv are given. To study this problem, a method was used to take soil samples according to the standard DSTU ISO 10381-4: 2005. To determine the content of petroleum products used the method MVV No. 081/12-0116-03 Pochvy. Based on the results of the study it was found that contamination with petroleum products in the study area exceeds the norm in the area of influence of the railway at a distance of 5 to –50 m on average 3.5 times. It is proposed to make management decisions to prevent violations of the sanitary protection zone of the railway and the placement of agricultural plots on it. For rehabilitation of contaminated soils, it is advisable to use a natural sorbent – glauconite, which is widespread in the bowels of Ukraine. The adsorption capacity of glauconite relative to diesel fuel has been experimentally established. According to our experiments it is proved the high efficiency of the proposed sorbent, which is 90%. Therefore, in the future it is necessary to periodically monitor the condition of the soil in the area to prevent pollution. This study proves that this practice is necessary.
Field and modelling study for deficit irrigation strategy on roots volume and water productivity of wheat
Authors: Abdelraouf Ramadan E. , El-Shawadfy Mohamed A. , Dewedar Osama M. , Hozayn Mahmoud
Published: November 2023

In many regions of the world, including Egypt, water shortages threaten food production. An irrigation deficient strategy in dry areas has been widely investigated as a valuable and sustainable approach to production. In this study, the dry matter and grain yield of wheat was decreased by reducing the amount of irrigation water as well as the volume of the root system. As a result of this, there was an increase the soil moisture stress. This negatively affected the absorption of water and nutrients in the root zone of wheat plants, which ultimately had an effect on the dry matter and grain yield of wheat. The values of dry matter and grain yield of wheat increased with the ʻSakha 94ʼ variety compared to the ʻSakha 93ʼ class. It is possible that this was due to the increase in the genetic characteristic of the root size with the ʻSakha 94ʼ variety compared to the ʻSakha 93ʼ class, as this increase led to the absorption of water and nutrients from a larger volume of root spread. Despite being able to increase the water productivity of wheat by decreasing the amount of added irrigation water, the two highest grain yield values were achieved when adding 100% and 80% of irrigation requirements ( IR) needed to irrigate the wheat and no signif-icant differences between the yield values at 100% and 80% of IR were found. Therefore, in accordance with this study, the recommended irrigation for wheat is at 80% IR which will provide 20% IR. When comparing the water productivity of two wheat varieties in study, it becomes clear that ʻSakha 94ʼ was superior to ʻSakha 93ʼ when adding the same amount of irrigation water, and this resulted in increased wheat productivity for ʻSakha 94ʼ. The SALTMED results confirmed good accuracy (R2: 0.92 to 0.98) in simulating soil moisture, roots volume, water application efficiency, dry matter, and grain yield for two varieties of wheat under deficit irrigation conditions.

The article presents an assessment of the effects of anthropogenic activities on the quality of water in four streams flowing through a camp based on a combined assessment of environmental impacts and the water quality index. The quantitative and qualitative assessment of environmental impact was made after identifying the anthropogenic activities carried out in the camp. The water quality index ( WQI) was calculated after monitoring seventeen physicochemical and microbiological variables and the Montoya index was applied. The samples were collected during 48 sampling campaigns, organised over the period of six months in eight stations. Two stations were located in each stream, one before and one after it passed through the camp. The results indicated that streams 1, 3, and 4 show a slight deterioration in water quality, affected by anthropogenic activities carried out in the said camp; meanwhile, stream 2 shows an increasing deterioration in water quality. The water quality of the streams before passing through the camp was determined to be between “uncontaminated” and “acceptable”, while after passing through the camp it was classified between “acceptable” and “slightly contaminated”. The results indicated a non-significant difference between the downstream and upstream WQI values for streams 1, 3, and 4; while stream 2 did show a significant difference in the WQI between upstream and downstream; indicating that anthropogenic activities alter the quality of the water.
Mean flow characteristics in a flat and eroded bed curved channel

The mean flow characteristics in a curved channel are really different from those in a straight channel. The main cause is the existence of secondary flow within the flow in the curved channel. This paper will discuss the differences in mean flow characteristics due to changes in the bed topography in the curved channel. Acoustic Doppler Velocimetry (ADV) measurements have helped to analyse characteristics of the mean flow on flat and eroded beds in a 180° curved channel. Sand (mean diameter d 50 = 0.001 m and specific gravity Gs = 2.65) was selected as the bed material. The condition of flow in the approach section was steady and uniform with 0.159 m depth. One of the mean flow characteristics in the curved channel is the free surface superelevation due to the presence of centrifugal force. The second is the circular motion toward the inner-bank region at the lower layer and toward the upper layer outer-bank region. The cause of the circulation is the difference in centrifugal forces between the two layers. The magnitude of velocity near the bed surface is more significant than the flow near the water surface. This causes erosion in the outer bank region and deposition in the inner bank region. In general, tangential velocity vθ in flat bed is greater than its tangential velocity in eroded bed. The maximum velocity path in a flat and eroded bed of the curved channel resembles a sinusoidal curve, where the minimum value is located at 90° and 120° of the curve.

With the emergence of climate change and the increasing human intervention in the global climate, floods have affected different parts of the world. In practice, floods are the most terrible natural disaster in the world, both in terms of casualties and financial losses. To reduce the adverse effects of this phenomenon, it is necessary to use structural and non-structural methods of flood risk management. One of the structural methods of flood control is to allocate a certain part of reservoir dams to flood control. In order to safely exit the flood from the dam reservoir, the spillway structure should be used. One of the important issues in designing a spillway structure is reducing its construction costs. In order to safely exit the flood with a specified return period from the dam reservoir, as the length of the spillway decreases, the height of the water blade on the spillway increases. In other words, decreasing the spillway length increases the height of the dam and its construction and design costs. In this study, the design and comparison of the performance of two glory spillways and lateral spillways have been considered. The results showed that for a given length for the drain edge of both types of spillways, the height of the water blade on the glory spillway is always higher than the lateral spillway. For example, when a 10,000-year-old flood occurs, it is about 8 m.

This work aimed to evaluate the yam peel in a bed column packaged as a chromium(VI) ion adsorbent in an aqueous solution. Yam peel was used as adsorbent, prior washing, drying, size reduction, and selection. The experimental work consisted in determining the effect of bed depth, particle size, and temperature, keeping inlet flow = 0.75 cm 3∙s –1, pH = 2 and initial concentration of 100 mg∙dm –3. The Adsorption Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray (EDS) analysis on yam ( Dioscorea rotundata) peel showed a heterogeneous, porous structure, with functional groups characteristic in lignocellulosic materials. It was analysed regarding the influence of temperature, bed height, and adsorbent particle size on the removal efficiency; it was found that the decrease of particle size and the increase of the bed height favour the elimination of the metallic ion, with removal rates between 92.4 and 98.3%. The bed maximum adsorption capacity was 61.75 mg∙g –1, and break time of 360 min. The break curve’s adjustment to the Thomas, Yoon–Nelson, Dose–Response and Adams–Bohart models was evaluated, concluding that the Yoon–Nelson and Dose–Response models best described the behaviour of the break curve with a coefficient of determination ( R2) of 0.95 and 0.96, respectively. The results show that the bio-adsorbent studied can be used to eliminate Cr(VI) in a continuous system.

The use of unmanned aerial vehicles (UAVs) is booming in almost every sector of the economy, especially in the agricultural industry. According to some reports, the agricultural UAV market is expected to increase from USD 2.6 billion in 2020 to USD 9.5 billion in 2030. In this paper a brief overview devoted to the use of UAVs in the Russian State Agrarian University – Moscow Timiryazev Agricultural Academy (RSAU-MTAA), including the results of studying the equipment use effectiveness for automatic driving of tractor equipment when sowing grain crops and planting potatoes. In the course of studying the equipment use effectiveness for automatic driving of tractor equipment, the deviations of the guess row spacing from the standard row spacing provided for by the seeder design were established; in the case of sowing barley using a marker, it was up to 4.3 cm, and in the case of winter wheat it was up to 5 cm. When using the autopilot system, these values were no more than 1.5 and 2.3 cm, respectively, which indicates the high accuracy and efficiency of the automatic driving systems. The autopilot system use provided a deviation of adjacent rows from the straightness when planting potatoes from 2.8 to 3.0 cm. The paper concludes that the use of unmanned robotic systems in agriculture, in conjunction with modern means of receiving and processing information, opens up new opportunities for increasing agriculture efficiency.

This work describes the behaviour of organic pollutants along the wadi Mouillah watercourse and its main tributaries and their impacts on the Hammam Boughrara dam, located in the NW of Algeria, in the Wilaya of Tlemcen. The use of a database relating to physico-chemical, biotic and hydrological variables, covering the period from January 2006 to December 2009, contributed to the understanding of the spatiotemporal evolution of each variable. The application of a mathematical model of the diffusion by convection-dispersion with a reaction on two characteristic parameters of organic pollution, the biochemical oxygen demand (BOD 5) which records values above the norm, with peaks that can reach 614%, and total phosphorus (P tot), which the concentration is always higher with maxima reaching 53 mg∙dm –3 favouring eutrophication; this made it possible with precision to synthesise the propagation of pollutants in the liquid mass. The results obtained on the waters of Wadi Mouillah are therefore of poor quality; there is a need to set up a rigorous water quality monitoring system, with water treatment and decontamination devices to preserve the water resources. This will allow to contribute to better management of water quality in terms of combating the spread of pollution. Therefore, they can be used to support decisions in the context of sustainable development.

Published: November 2023

Polluted water poses significant health risks when it is part of the water sources used for irrigation, leading to the contamination of soil and plants by various pollutants. This work aims, firstly, to assess the degree of pollution of Wadi El Gourzi water (Batna, Algeria), and then to verify the consequences on their use for the irrigation of market garden plants for everyday consumption (lettuce, cilantro, parsley and spinach), both in the aerial part (stems and leaves) and in the soil where they are grown. This study focuses on trace metals (Cr, Pb, Zn and Cd). Soil pollution was assessed by calculating the soil pollution index ( PI), while the uptake of these elements by plants was monitored by the transfer factor ( TF). The analyses of the Wadi El Gourzi water with the flame atomic absorption spectrophotometer (FAAS) show a maximum abnormal concentration of Cr (17.37 mg∙dm –3), Pb (0.71 mg∙dm –3) and Cd (0.45 mg∙dm –3). For the analysis of the soils irrigated by these waters, the results of the PI show that the soils used for the cultivation of parsley and lettuce are polluted by several metals ( PI > 1). The concentrations of trace metals elements (TMEs) in the sampled plants show a significant accumulation of Zn, Cd, Pb and Cr by the vegetables (coriander, parsley, spinach and lettuce). These concentrations are above the permitted standards.

The configuration of the smart irrigation system was designed on the basis of data specific to the parameters concerning characteristics of the plant and the pedological properties of the local soil (permeability, pH, humidity, porosity, etc.), including the meteorological factors. In the Chlef area, the water availability is dependent on meteorological data. The objective of this work is to estimate irrigation water needs in crop gardening (potato) based on a smart irrigation system (SIS). Thus, to ensure an equilibrated growth of crops, we have developed a system with parameters, such as soil moisture and soil temperature, which are the input variables of this smart irrigation system. This system was applied for the irrigation of potatoes (‘Bartina’ variety), planted in the agricultural experimental station of Lard El Beida at Chlef. The results obtained in terms of production yield led to a conclusion that the smart irrigation system allows achieving production of 124.83% with lower water consumption (–19.31%), compared to that of a drip irrigation system. Moreover, the granulometric analysis of the potato tuber size showed that 80.83% of the production is within the size range between 30 mm and 55 mm. By comparison, we observed that 77.4% of products obtained from drip irrigation follow a uniform distribution. We conclude that this smart irrigation system is very economical in terms of water use for gardening crops. Given these encouraging results, it would be wiser to generalize its application and implement it to guarantee food self-sufficiency in the water-deficient regions.
