The more rapid growth of technology allows humans to work effectively and efficiently. Technology proves the way humans change patterns of significant social change, from those that initially used human power to machines. The way humans use machines is inseparable from the ways and techniques of its use which are effective and efficient. One of the technologies used is the technology of crop cultivation without using soil as a planting medium. The technology introduced is hydroponics. Hydroponics as a way of farming is an approach that has several advantages, namely the use of agricultural land that is not extensive, and the system is not too complicated. The introduction of this technology aims to provide insight and knowledge to the public about the technology of crop cultivation in addition to conventional farming systems. This activity was carried out in Rayung gumuk Village, Glagah District, Lamongan Regency. The hydroponic system that we introduce is the NFT hydroponic system (Nutrient Film Technique). The goal is because the hydroponic system is easily applied and has several significant advantages. The first method of implementation is socialization.This is done to find out the extent to which people's insights and knowledge about hydroponics and the interests and interests of the community towards hydroponic using the NFT system. Moreover, the second is training. It aims to provide techniques and methods for assembling NFT hydroponic installations. From the results of our activities, the community's response to hydroponics is still minimal because some of them still consider hydroponic use too costly and their disinterest in agriculture.

Abstract. Hydroponics can allow crops to grow faster and can reduce plant pathogens. However, hydroponic systems have several disadvantages, of which the two most important are: (1) improper management or dramatic changes in the electrical conductivity (EC) and pH of the nutrient solution can harm the plant roots and affect the plant growth, and (2) system operators need to monitor the nutrient solution and replenish it regularly, thereby increasing the labor cost. Therefore, this study developed a micro-electro-mechanical systems (MEMs) based mixing system for hydroponic nutrient solutions based on fuzzy rule-based inference, which uses a micro-controller as the core and controls the output of five nutrient solution tanks to the mixing tank. The proposed system maintained an appropriate range of pH and EC in the mixing tank. Operators can view the changes in pH, EC, dissolved oxygen (DO), and other values in the nutrient solution on a graphic user interface. Moreover, operators can manually or automatically mix the nutrient solution. The system has been implemented in a hydroponic cultivation system, and the analysis results are discussed in this article. Keywords: Fuzzy logic, Hydroponics, Microcomputer.

Full textAbstract:
Hydroponics is crucial for providing feasible and economical alternatives when soils are not available for conventional farming. Scholars have raised questions regarding the ideal nutrient solution flow rate to increase the weight and height of hydroponic crops. This paper presents the turbulent kinetic energy distribution of the nutrient solution flow in a nutrient film technique (NFT) hydroponic system using the computational fluid dynamics (CFD) method. Its main objective is to determine the dynamics of nutrient solution flow. To conduct this study, a virtual NFT hydroponic system was modeled. To determine the turbulent kinetic energy distribution in the virtual NFT hydroponic system, we conducted a CFD analysis with different pipe diameters (3.5, 9.5, and 15.5 mm) and flow rates (0.75, 1.5, 3, and 6 L min−1). The simulation results indicate that different pipe diameters and flow rates in NFT hydroponic systems vary the turbulent kinetic energy distribution of nutrient solution flow around plastic mesh pots.

Full textAbstract:
A comparison of leafy green plant species’ (lettuce (Lactuca sativa L.), dill (Anethum graveolens L.), rocket (Eruca sativa), coriander (Coriandrum sativum L.), and parsley (Petroselinum crispum)) growth rates was performed between an Nutrient Film Technique (NFT)hydroponic system, using standard commercial nutrient solution, and an NFT aquaponic system, using fish waste from Grass Carp, (Ctenopharyngodon idella) which provided the majority of the nutrients required by the plants. The results demonstrated that the aquaponic method performed well, and, in many cases, the growth rates produced were similar to those of the hydroponic method. Lettuce growth was compared across three seasons (summer, winter, and spring), and, in all cases, the aquaponically-grown lettuce equalled, or bettered, the hydroponic equivalent. Herb growth was compared over a five-month period (February to June—summer/autumn), and in 17 out of 23 comparisons, the aquaponic method produced results similar to those of the hydroponic method. Thus, while the NFT method may not be the most appropriate technical approach for aquaponic integration, the results suggest that the overall aquaponic method has the potential to produce plant growth rates at least equal to those of standard hydroponics.

This research helps the farmers to do the humidification control and monitor the condition of hydroponic plants in greenhouses in real-time. When it comes to watching the hydroponic plants in greenhouses, the farmers usually experience difficulties because they still do it manually. Activities such as checking the temperature, air humidity, and also water quality in hydroponic plants by coming directly to the greenhouse are still ineffective. Therefore this research aims to make a smart greenhouse prototype for hydroponic plants. Smart greenhouse hardware was built based on the Arduino microcontroller, DHT11 sensor, pH sensor, TDS, DS18b20 temperature, ultrasonic, and esp8266 wifi module. The monitoring system features information on water quality from hydroponic plants and the ability to record farming activities from planting preparation to web-based harvesting. The test results of smart greenhouse monitoring system can display the hydroponic plant conditions and able to do the humidification control with an upper limit of 35 degrees celsius because plant can survive with disease under 35 degrees celsius, with small average offset for the sensor, and an average offset of 1.49 from TDS sensors, with temperature of 0.50 and pH of 0.34.

With the impact of decreasing arable land and the rapid growth of global population, more people are beginning to attach importance to hydroponic systems, which is an innovative solution that may efficiently solve this problem. The incredible growth of the global hydroponic market has already raised many entrepreneurs’ or even countries’ attentions. There is a multitude of research, which has already proven that plants grow much faster in hydroponic systems, and have more nutrients than plants grown from soil. However, many scientists also found out that having a totally closed system may also promote the spread of pathogens and pests, which can cause a great amount of economic loss to hydroponic operators. Therefore, reliable and efficient methods of preventing harmful organisms to enter the system are imperative and crucial for ensuring successful hydroponics management. This research was done in order to discover if there is a semipermeable membrane which can block the algae or fungus outside, but allow the dissolved nutrients to enter the hydroponic system. In addition, this would reduce the cost of cleaning hydroponic systems and utilize a material that is friendly to the environment. It was hypothesized that by combining several coffee filters, which are biodegradable, this goal may be accomplished. In the first experiment, a cup with coffee filters was placed in algae water to observe if coffee filters can work efficiently for at least 3 days. In the second experiment, a “jar test” was performed for different types of filters, and it was indicated that essential coffee filters can block out algae by 100%. Finally, the last experiment involved implementing the filters in a hydroponic system. The results show that coffee filters in the hydroponic system are capable of blocking out most of algae.

Lettuce (Lactuca sativa L.) is the most commonly consumed leaf vegetable in the Brazilian diet, and it is a good source of vitamins and minerals. It is widely grown in the conventional farming system. However, the hydroponic farming system has been gaining importance in the market, wining confidence from consumers, who are becoming increasingly more demanding on food quality. The objective of this study was to evaluate the performance of two lettuce cultivars on hydroponic and conventional farming systems for the production of fresh mass (FM) and dry mass (DM), photosynthesis, contents of chlorophyll and anthocyanin. The following two experiments were carried out: hydroponics farming (HF) and conventional farming (CF), performed in protect and unprotect environments, respectively, in Florianópolis, SC. Mimosa Verde cultivar (MV) showed greater fresh mass than Mimosa Roxa (MR), in both farming systems and the two cultivars presented better performance in the hydroponic system (287.7 g MV and 139.1 g MR) than the conventional system (129.7 g MV and 111.8 g MR). Mimosa Verde cultivar presented lower average contents of total chlorophyll (7.7 mg g-¹ FM) than Mimosa Roxa (11.8 mg g-¹FM), and both cultivars displayed higher means for this variable in the hydroponic farming system. Mimosa Roxa presented higher contents of anthocyanin in the conventional system (88.24 mg g-¹ FM) than the ones in the hydroponic system (36.89 mg g-¹ FM). The best results for CO2 net assimilation rate regarded to photosyntheticaly active photon flux density were found in the hydroponic system, for both lettuce cultivars. Variation in the contents of chlorophyll were also found. Those variations were higher in the protected system than in the hydroponic system and contents of anthocyanin were higher in the conventional system.

Hydroponic vegetable cultivation for PKK mothers aims to produce safe household-scale vegetables. This activity was an opportunity for the community to increase income. Community service activities were carried out in Pagarawan Village, Merawang Subdistrict, Bangka District in May–August 2018. The purpose of community service activities was to provide counseling and training on plant cultivation with a hydroponic system. Kind of vegetables that are cultivated are mustard greens. The hydroponic system that was socialized to participants was a floating and flowing hydroponic system using a wick. The results of a survey to training participants showed that 38.46 strongly agreed, 61.54 agreed, and 0 disagreed with hydroponic vegetable cultivation. The results of SWOT analysis showed that to increased community motivation in conducting hydroponic crop cultivation there needs a capital/investment, support from academics, and the government. The results of analysis of mustard greens farming in hydroponics require an initial capital of IDR 2,016,000, a profit of IDR 502,570/month, and venture capital can be returned within 4 months. The hydroponic plant system is very good to be developed because besides being able to meet the needs of vegetables for the household it can also increase family income.

Full textAbstract:
Intensive swine farming causes strong local environmental impacts by generating effluents rich in solids, organic matter, nitrogen, phosphorus, and pathogenic bacteria. Insufficient treatment of hog farm effluents has been reported for common technologies, and vermifiltration is considered a promising treatment alternative that, however, requires additional processes to remove nitrate and phosphorus. This work aimed to study the use of vermifiltration with a downstream hydroponic culture to treat hog farm effluents. A treatment system comprising a vermifilter and a downstream deep-water culture hydroponic unit was built. The treated effluent was reused to dilute raw wastewater. Electrical conductivity, pH, and changes in BOD5, ammonia, nitrite, nitrate, phosphorus, and coliform bacteria were assessed. Plants were monitored throughout the experiment. Electrical conductivity increased due to vermifiltration; pH stayed within a neutral to mild alkaline range. Vermifiltration removed 83% of BOD5, 99% of ammonia and nitrite, and increased nitrate by 11%. Hydroponic treatment removed BOD5 (63%), ammonia (100%), nitrite (66%), nitrate (27%), and phosphorus (47% total and 44% dissolved) from vermifiltered water. Coliforms were reduced by vermifiltration but recovered in the hydroponic unit. Plants showed the ability to grow on vermifiltered wastewater, although requiring nutrient supplementation. Vermifiltration combined with hydroponics is a promising treatment for swine wastewater, although optimization will be needed for a sustainable real-scale implementation.

Unlike conventional agriculture, urban hydroponics are widely on a small yard scale. Hydroponics is a term used for farming without using soil as a growth medium. Plants can be planted in pots or other containers using water and other porous materials as growing media. Cheap, easily obtainable, and efficient growing media types are needed for urban communities to cultivate vegetable crops, especially shallots (Allium ascalonicum L.). Shallots have an important meaning, both in terms of high economic value and their nutritional content. It is unknown if the shallots are cultivated in a hydroponic system and how the performance of its roots and the suitable simple growing media for growing shallots in hydroponic will be enhanced. Therefore, this research was conducted to study the performance of shallot roots in several alternative hydroponic media and obtain growing media that can provide the best growth on the performance of shallot roots in the hydroponic system. The experiment was conducted in 3 months at the Glass House and Integrated laboratory of the Faculty of Agriculture, Mulawarman University, Indonesia. This research was arranged in a Randomized Block Design (RBD) with four replications. The factor is the growing media (m) which consists of 4 levels, namely: m1 = sand (± 80-100 mesh); m2 = burnt rice husk; m3 = egg cartons; and m4 = wood shavings (± 90-120 mesh). Data retrieval by observing the following parameters: Leaf length (cm), Number of leaves (strands), Number of plant bulbs (bulbs), bulbs wet weight (grams), bulbs dry weight (grams), Longest root length (cm), and Total root length (m). This research showed that the burnt rice husk and wood shavings growing media influence the growth and performance of the shallots' roots (Allium ascalonicum L.) plants and can be used as the simple growing media in urban hydroponic as Household scale cultivation. On the other hand, the growing media from sand and egg cartons are not recommended for growing shallots in the hydroponic system.

The monitoring system in nutrient solution is something that must be considered in the process of hydroponic cultivation, because it is from this nutrient solution that ensures the result and quality of the hydroponic plant itself. Important variables such as acidity, temperature and concentration of nutrient solution are the values that determine whether or not the nutrient solution will be given to the hydroponic plant. Important variables in improper nutrient solutions will make the hydroponic cultivation process for crop failure. This research uses a PH sensor that serves to detect the acidity level of the nutrient solution and the DHT11 temperature sensor which functions to read the condition of the nutrient solution temperature and the TDS sensor detects the concentration of the nutrient solution. The microcontroller used is the type of Atmega328 which is used as a processing of all inputs and outputs. This monitoring system is connected to the internet so that all sensor reading values can be viewed through an Android phone and can be accessed via the Web, so that the monitoring process can be done remotely. From the test results obtained prove that this system has been successfully integrated and is able to work well according to the desired target, which can monitor the acidity and temperature conditions in hydroponic plants that can be accessed directly through mobile phones and has been integrated with the internet network.

<p style="text-align: justify;">Cauliflower has a high consumption level but its production is limited to its region in the highlands and the planting season. An effort to increase its production outside the highland in all seasons is using hydroponics on tolerant varieties. Selection of varieties and giving the right amounts of nutrients will optimize the production of lowland cauliflower. This study aims to determine the types of varieties and concentration of nutrient solution suitable for the cultivation of hydroponic cauliflower in the lowlands. This research uses a Completely Randomized Design (CRD) which consists of 2 factors namely varieties and nutrient solution concentration level with 9 combination treatments and each treatment consisted of 4 plants. The results showed that variety of Mona and PM 126 are better than the Diamond in the hydroponic cultivation of cauliflower in the lowlands. Concentrations of the nutrient solution did not improve growth and show no significant results, so nutrient solution from EC 2.2 to 2.4 mS/cm is better in the hydroponic cultivation of cauliflower in the lowlands.</p>

Abstract Besides soil cultivation, there are other alternative methods such as the aquaponic and the hydroponic technology. In our research, four lettuce varieties (‘Edina’, ‘Május királya’, ‘Lollo Rossa’, and ‘Lollo Bionda’) were compared by the use of different systems. In hydroponics, the direct nutrient supply resulted higher leaf weight. In addition, multiple values of nitrate (269.50–406.50 mg kg-1) were measured in this system compared to the aquaponic system (23.25–170.00 mg kg-1). The ‘Lollo Rossa’ stood out with higher element content (Zn, B, and Mg) in both cultivation methods. In conclusion, it can be stated that higher nutrient content in hydroponics resulted higher leaf weight, but nitrate values were also higher in this unit. Aquaponic technology can be used to produce high-quality (low-nitrate) lettuce with the ‘Lollo Rossa’ and ‘Lollo Bionda’ varieties.

Dry hydroponic is an emerging system and gaining popularity among some hydroponic businesses, yet investigation on its performance has not been reported. Purpose of this research is to evaluate and compare performance of dry hydroponic system to floating and wick systems on green leafy lettuce cultivation. The experiment used Completely Randomized Design (CRD) with factorial arrangement. Two factors, hydroponic systems and aerator usages, were implemented. The hydroponic systems included Dry, Wick and Floating systems, while the use of aerator were with and without aerators. All treatment combinations consisted of 3 replicates. Parameters to be observed were nutrient solution parameters (pH, temperature, dissolved oxygen, water consumption), plant parameters (height, stem diameter, leaf width, number of leaves, leaf thickness, and canopy area, shoot fresh weight, water content, some chemical contents). Data sets were analyzed using analysis of variance followed by a least significant Difference (LSD) test at level of 5%. Results showed that the interaction between the hydroponic system and the use of aerators were not significantly different for all parameters observed. The hydroponic systems were not significantly different too. The use of aerator was significant for the nutrient solution parameters (pH and Dissolved Oxygen), water content, and phosphorus contents of leaves. In conclusion, Dry Hydroponic System has the same performances as compared to floating and wick systems.

Subsistence and smallholder farmers in the Deccan plateau region of India struggle with a predominantly hot and dry climate and often accumulated debt due to the cost of fertilizer that they need to increase yields for profitability. While a low-cost deep-flow technique hydroponic growing system (DFT) as a supplement to soil-based agriculture could help reduce debt, the cost of electricity needed to operate the DFT makes it inaccessible to these farmers. The objective of this project was to test the viability of electricity-free DFT which would substantially reduce production costs. Two DFT systems were set up in a shade net house and prepared with identical nutrients to grow chili pepper seedlings. Each DFT system was oxygenated for 30 minutes per day, one system using an electrical air pump, and the other system was oxygenated manually. After four weeks of growth, the dry mass of the shoots of the chili pepper seedlings in each system was measured. While the pump-oxygenated DFT system produced more dry matter, the manually-oxygenated system produced a larger number of visually healthier plants. Therefore, we conclude that electricity-free DFT hydroponics may be a viable alternative to pump-oxygenated DFT hydroponics, making hydroponic farming a cost-effective option for poor farmers.

Hydroponics is the cultivation of plants by utilizing water without using soil by emphasizing the fulfillment of nutritional needs for plants. Deep Flow Technic (DFT) is a type of hydroponics that implements a continuous flow of nutrients and there is a pool of half of the diameter of the pipe that inundates the roots of the plant. A common obstacle experienced by DFT is the lack of maintenance of plant growth elements such as water circulation, light intensity, temperature, humidity and pH of the water which causes these plants not to grow optimally. Then it is necessary to monitor and control the circulation of water on DFT-based IoT hydroponics to anticipate changes in plant growth elements. Data on plant growth elements are acquired by sensors integrated with Raspberry Pi. In the monitoring process using the website will display data on plant growth elements in the form of pH, temperature, humidity and water level in the hydroponic reservoir. Temperature and humidity are used as water circulation control parameters that are processed using the Fuzzy Sugeno Method. From the results of the tests that have been carried out, the system can monitor plant growth elements displayed on the website in real time and control water circulation automatically. The system applied in the hydroponics of mustard greens also produces significant growth in leaf number and plant height.

Carbon dioxide is produced by microbial and plant respiration and accumulates in the soil. In previous field studies, CO2 levels were higher under a killed sod soil management system, relative to cultivation and herbicide systems (1.8 vs 0.8 and 1.0%), respectively. Our objective in these studies was to measure the effect of elevated levels of root system CO2 on root and shoot growth and nutrient uptake. Using soil and hydroponic systems in greenhouse studies, we maintained root system CO2 levels between 1.5 and 2.5%. Control CO2 levels were less than 1%. Root length density and dry matter partitioning to the root system were increased by root CO2 in soil and hydroponic studies; shoot growth was unaffected. In hydroponic culture, root CO2 increased P uptake, solution pH, root volume and the number of lateral roots/cm root axis. Elevated levels of CO2 in the root system stimulated root growth in both the soil and hydroponic studies.

Lettuce becomes the main ingredient of salad as one of the healthy foods. The lettuce cultivation in tropical areas is often performed in highland. To reduce soil erosion and pesticide contamination, the cultivation of lettuce plants in high open land needs to be reduced. The lettuce cultivation in hydroponic system at tropical lowland requires cooling. The root zone cooling requires enormous electrical energy. However, it can be solved by controlling the temperature based on the automatically. Therefore, it has been developed control and monitoring system for the root zone on floating raft hydroponic system. This study aimed to evaluate the photosynthetic rate of lettuce cultivated in floating raft hydroponic system whose nutrient solution was controlled by the developed control and monitoring system. Statistical analysis was performed to draw the conclusions about photosynthetic variance of lettuce on two hydroponic systems, namely controlled and uncontrolled system. Furthermore, this paper presents an artificial neural network (ANN) model to estimate the photosynthetic rate of lettuce cultivated in the hydroponic systems. The ANN model was comprised of eight input (nutrient temperature, EC, pH, DO, and ORP, air temperature, air humidity, and photon flux density of photosynthetic) and one output (photosynthetic rate). It was noted that the ANN model predicted accurately the photosynthetic rate of lettuce leaves whose R2 was 0.87 for plants cultivated in floating raft hydroponic system whose nutrient solution was controlled by control and monitoring system. The ANN was useful for identifying the photosynthetic rate of lettuce cultivated in floating raft hydroponic systems on tropical lowland.

The limitations of conventional soil cultivation in producing medicinal plants emerge an interest in searching various alternative cultivation systems, one of which is the hydroponic system. This study aimed to investigate the effect of various substrates in non-circulating hydroponic systems and soil media on the growth of Gynura procumbens. Non-circulating hydroponic cultivation of Gynura procumbens was carried out using stem cuttings. The stem cuttings were transferred to each net pot containing substrates such as rockwool, tree ferns fiber, and sawdust. The net pots were then placed in a tray comprising AB mix 6 ml/L of water. The lower 2-cm-portion of the net pots was immersed in a nutrient solution. Whereas in the conventional soil cultivation, the stem cuttings were transferred to the polybags containing soil media: compost (1: 1). After 28 days of cultivation, the plant growths were measured. The results showed that the use of various substrates in non-circulating hydroponics increased plant growth compared to conventional soil cultivation. Rockwool treatment obtained the highest number of leaves (14,833 ± 5,269 strands), number of roots (20,333 ± 6,121 stands), fresh weight (1.34 ± 0.511 g) and dry weight (0.088 ± 0.031 g).

Hydroponics is an effective means for promoting plant growth as it facilitates water and nutrient uptake by plant roots. For increasing the production of sweetpotato (Ipomoea batatas), we developed the new hydroponic cultivation system in which tuberous roots were grown in solid media in the pots whereas fibrous roots were grown in the nutrient solution. Using this method, the effect of pot volume (1.6, 3.0, and 4.5 L) on the growth of sweetpotato was investigated. When plants were grown in small-sized pots (1.6 L), the fresh weight of the top and that of tuberous roots were decreased compared with plants grown in 3.0 L and 4.5 L pots. No clear difference was observed between the top and the tuberous roots in terms of the dry weight ratio, regardless of the pot size. The number of tuberous roots per plant and the maximum tuberous root weight were not influenced by the pot size either. However, the number of tuberous roots weighing more than 100 g was decreased in plants grown in small pots. Some of the tuberous roots grown in this hydroponic system contained a non-hypertrophic parts with severely lignified metaxylems. These results suggest that the environment surrounding the tuberous root influenced by the pot volume may be important for root enlargement in this hydroponic system.

ABSTRACT The desire for local, fresh produce year round is driving the growth of hydroponic growing systems in the United States. Many food crops, such as leafy greens and culinary herbs, grown within hydroponics systems have their root systems submerged in recirculating nutrient-dense fertilizer solutions from planting through harvest. If a foodborne pathogen were introduced into this water system, the risk of contamination to the entire crop would be high. Hence, this study was designed to determine whether Escherichia coli O157:H7, non-O157 Shiga toxin–producing E. coli, and Salmonella were able to survive and reproduce in two common hydroponic fertilizer solutions and in water or whether the bacteria would be killed or suppressed by the fertilizer solutions. All the pathogens grew by 1 to 6 log CFU/ml over a 24-h period, depending on the solution. E. coli O157:H7 reached higher levels in the fertilizer solution with plants (3.12 log CFU/ml), whereas non-O157 Shiga toxin–producing E. coli and Salmonella reached higher levels in the fertilizer solution without plants (1.36 to 3.77 log CFU/ml). The foodborne pathogens evaluated here survived for 24 h in the fertilizer solution, and populations grew more rapidly in these solutions than in plain water. Therefore, human pathogens entering the fertilizer solution tanks in hydroponic systems would be expected to rapidly propagate and spread throughout the system and potentially contaminate the entire crop.

Hydroponics is a farming technology using water mixed with mineral nutrients which is continuously flowed to the roots of plants for 24 hours every day. The height of the water reserves, the water temperature, the nutrient content of the water and the pH of the water are some of the factors that need to be considered in planting crops using the hydroponic method. Regular observations and control functions of water quality are very important to ensure hydroponic plants can grow well. The function of controlling and observing water quality can be accomplished by developing a hardware system with an embedded Web equipped with a dosing-pump module to determine water quality based on the calculation of input data from the water quality sensor. With the embedded Web application, the control and observation functions can also be carried out remotely and periodically the hydroponic system can report the current state directly via the TCP/IP network. In this study, a second generation minimum system model will be developed which is the result of improvements from previous research. Water pH and water conductivity (EC) sensors can be activated simultaneously. The addition of a dosing-pump module is used to provide a liquid to adjust the pH value of water and plant nutrient fluids, while the addition of an embedded Web application to a Wi-Fi hardware module is to improve the ease of control and monitoring functions.

Full textAbstract:
Aquaponics combines the hydroponic production of plants and the aquaculture production of fish into a sustainable agriculture system that uses natural biological cycles to supply nitrogen and minimizes the use of nonrenewable resources, thus providing economic benefits that can increase over time. Several production systems and media exist for producing hydroponic crops (bench bed, nutrient film technique, floating raft, rockwool, perlite, and pine bark). Critical management requirements (water quality maintenance and biofilter nitrification) for aquaculture need to be integrated with the hydroponics to successfully manage intensive aquaponic systems. These systems will be discussed with emphasis on improving sustainability through management and integration of the living components [plants and nitrifying bacteria (Nitrosomonas spp. and Nitrobacter spp.)] and the biofilter system. Sustainable opportunities include biological nitrogen production rates of 80 to 90 g·m−3 per day nitrate nitrogen from trickling biofilters and plant uptake of aquaculture wastewater. This uptake results in improved water and nutrient use efficiency and conservation. Challenges to sustainability center around balancing the aquaponic system environment for the optimum growth of three organisms, maximizing production outputs and minimizing effluent discharges to the environment.

The occurrence of anaerobic conditions in hydromorphic soils favors the development of anaerobic microorganisms that produce phytotoxic substances representing primarily by organic acids. The selection of promising oat (Avena sativa L.) genotypes for use in those situations requires field evaluations that can be cumbersome, making hydroponics a viable alternative. The objective of this work was to adjust a methodology to use in studies of tolerance to organic acids in oat under hydroponic systems. For such goal, the best germination system was determined in order to reduce the seedling initial establishment effects under hydroponics, the ideal concentration for screening genotypes and the best variable for stress evaluation. It was found that the most efficient germination system was "pleated germination paper" with small and husked seeds. The best concentration for studying organic acid tolerance ranged from 2.3 to 6.2 mM and the most suitable variable for the evaluation was root length.

Aim of the study: We developed a faster micropropagation protocol specifically designed for Eucalyptus grandis. Eucalyptus breeding programs use micropropagation protocols to obtain high quality cloned seedlings, but current protocols are excessively time consuming.Area of the study: The protocol has been developed in Argentina, but it can be applied in anywhere.Materials and methods: We used nodal segments as initial explants to obtain micropropagated shoots, which were then simultaneously rooted ex vitro and acclimated in a hydroponic system. Nodal segments were cultured in a MS medium supplemented with 1 mg l-1 6-benzylaminopurine, 30 g l-1 sucrose, 1 g l-1 active charcoal and 8 g l-1 agar and incubated for four weeks at 25 ± 2°C under 16 h day photoperiod. Then, micropropagated shoots were exposed 15 seconds to 5000 ppm indol-butyric acid prior to being transferred to a hydroponic system, allowing simultaneous ex vitro rooting and acclimatization.Main results: 73 ± 9% of nodal segments grew to generate 1.73 ± 1.03 shoots per explant (length: 0.76 ± 0.44 cm). After four weeks in hydroponic system, 46 ± 4 % of micropropagated shoots developed roots, which represents an acceptable and intermediate rate of success, compared to the reported in vitro rooting rates.Research highlights: Our protocol allowed to obtain micropropagated seedlings in a total timespan of 8 weeks. Our results show that, by utilizing a hydroponic system, traditional protocols to micropropagate Eucalyptus can be substantially enhanced, allowing for improved production dynamics and potentially resulting in better organized seedling manufacturing facilities.Keywords: Woody plants; silviculture; nursery seedlings; rooting methods; hydroponics; acclimatization.

Full textAbstract:
Aquaponic is considered one of alternative culture system to improve production and quality of leafy vegetables by combining soil less culture and fish farming. Utilization of fish manure contained in waste water provides nutrient sources for growing plants. Three kinds of leafy vegetables including water spinach (Ipomoea aquatica F.), green coral lettuce (Lactuca sativa L.), and bok choi (Brassica rapa L.) were grown using both aquaponic and hydroponic system at the Green House in Serut village, Panti District, Jember Regency, from April to June 2019. Productions of each leafy vegetable were evaluated on both culture systems. Water spinach represented 29.12% higher production in aquaponic than hydroponic system, shown by significant value in plant height, number of leaves, root volume, and leaf fresh weight. Otherwise, bok choi production displayed 17.03% increased in hydroponic than aquaponic system. However, leaf production of lettuce was not significant between hydroponic and aquaponic system. Lettuce production in aquaponic only 1.90% lowest than hydroponic system indicated that lettuce was appropriate to cultivate in both farming systems.

Full textAbstract:
Hydroponics is a system of growing plants in nutrient solutions which could be from organic or inorganic sources with or without the use of aggregate medium. It is an alternative way of growing vegetables that would overcome problems encountered in conventional farming like soil acidity, alkalinity, and soil-borne diseases. This study was conducted to evaluate the growth, yield, and profitability of ampalaya varieties grown under aggregate hydroponic systems using different nutrient solutions. The experiment was laid out in a Factorial Randomized Complete Block Design with three replications using ampalaya hybrids as factor A and nutrient solutions as factor B. The two ampalaya hybrids (Galaxy and Jade Star) applied with commercial solution showed significantly greater values in terms of horticultural parameters, yield, and yield components. Between the two ampalaya hybrids, no significant effect was observed in most of the characteristics except on the weight of roots. Galaxy had heavier roots compared to Jade Star. Consistent superiority of plants applied with commercial solution was manifested in most parameters. The overall results revealed that production of ampalaya hybrid using an aggregate hydroponic system is profitable.

Full textAbstract:
The use of desalinated seawater (DSW) as an alternative to conventional water resources is gradually gaining more interest due to the strong water deficit and increasing pressure on water resources in semi-arid regions. Furthermore, the combination of this alternative irrigation with the hydroponic cultivation system would allow continuous production almost through the whole year and hydroponic-related high crop yield. Nevertheless, the effects of DSW irrigation in hydroponic systems on the product quality need to be firstly studied to avoid product quality losses. In this study, we evaluated the effects on the quality of two tomato cvs. (Ramyle and Racymo) of three different irrigation treatments (T1, DSW; T2, DSW/well water mix; and T3, well water) under hydroponic or traditional cultivation systems. The soluble solid content of samples (highly correlated to dry matter content) grown under hydroponic conditions and T3 irrigation showed the highest values (5.8 °Brix) although such differences (<0.6 °Brix) with T1 might not be sensorially appreciated. Similarly, although T3 samples showed higher acidity than T1 samples, such differences (0.06%) would be not appreciated by the consumer. Tomatoes grown in hydroponic conditions had 1.1–1.2-fold higher firmness than conventional soil conditions showing hydroponic T3 samples had the highest value (21–23 N). Tomato cv. Racymo displayed higher color index (chroma) than cv. Ramyle, registering hydroponic T1 samples the most intense red color correlated with the highest lycopene content of 41.1 mg/kg. T1 irrigation of tomatoes cv. Ramyle did not induce significant changes while differences lower than 10% were observed in the tomato cv. Racymo. The highest total antioxidant capacity, which was highly correlated to the total phenolic content (R2 = 0.80), was found for hydroponic T1 samples with 1637/1243 µmol/kg for the tomato cvs. Ramyle/Racymo. Conclusively, the use of DSW would not compromise the consumer acceptance of tomatoes due to the low (not appreciable) quality differences, with even the total antioxidant capacity of these samples being increased. Furthermore, the mix of DSW with conventional water resources (lower cost) would not compromise the tomato quality.

Full textAbstract:
Hydroponics is a modern way of growing plants in special solutions. Using this method, plants dispense with soil, are in the substrate, which serves as a support for the root system and receive the necessary nutrients from the solution. It for each plant, depending on the species, is selected individually. The hydroponic method is of two types: open systems and closed. Most industrial plants are simple open systems. Plants are grown on a mineral wool slab; the nutrient solution circulates several times a day, according to the ambient temperature, and then after each watering 25-30% of the nutrient solution is discharged into the ground. This is to prevent the deposition of salts on the substrate.There are also closed systems where the nutrient solution circulates from the tank to the plants and back to the tank. In this case, all the consumed water is absorbed and evaporated by the plant, thereby increasing the efficiency of water consumption. In addition, the nutrient solution does not come into contact with the soil and does not contaminate the soil, and unwanted nutrients do not enter the groundwater. System closure solves the problem of water loss. Peppermint culture was grown using a closed type of hydroponic system. Passiflora seeds were grown using mineral wool.
