Abstract:
Water scarcity has necessitated the adoption of water-saving techniques in both protected and non-protected farming. This study aimed to evaluate the performance of a water-saving soilless cultivation technique and compare it to conventional soil-based cultivation in protected farming. The soilless technique utilized local gravel and a mixture of peat moss, humin-substrate, and perlite in a 4:3:1.5 ratio. During the tomato growth cycle, three irrigation regimes were imposed using drip irrigation: 8 Lh−1 design discharge (D1) emitters, 6 Lh−1 design discharge (D0.75) emitters, and 4 Lh−1 design discharge (D0.5) emitters for both cultivation methods. Vegetative growth, fruit yield, and water consumption were measured and water productivity was determined. Additionally, an economic assessment was conducted by estimating and comparing economic coefficients for both cultivation methods. Estimated coefficients included revenues, net profit, benefit–cost ratio, breakeven levels of production and prices, revenues over variable cost, and revenues on investment. The tomato fruit yield under soil-based cultivation surpassed the yield under soilless cultivation. Water productivity under soilless cultivation was nearly double (24.3 kg m−3) that of soil-based cultivation (15.5 kg m−3). Soilless cultivation saved 50% of the irrigation water applied by the conventional soil-based method, conserving energy and protecting the soil from deterioration. Revenues and net profits, driven by higher yield and lower variable costs, favored soil-based cultivation. The economic assessment demonstrated that both cultivation methods were economically viable. However, the soil-based cultivation method was more profitable due to its higher fruit yield. Overall, the results of this study suggest that the soilless cultivation technique is a feasible option for water-saving cultivation. However, the soil-based cultivation method remains more profitable due to its superior fruit yield. The soilless cultivation technique offers significant water savings but needs further improvements to achieve comparable economic returns to traditional farming.

Abstract:
With the growing challenges of food security and environmental degradation, there is an increasing need for sustainable agricultural practices. Soilless cultivation techniques offer a promising solution by minimizing land and water use while maximizing crop yield and quality. This review examines the potential of soilless cultivation methods in promoting sustainable agriculture. The purpose of this review is to evaluate the effectiveness of soilless cultivation techniques in sustainable agriculture. It aims to analyze the various methods used, their advantages and limitations, and their contributions to environmental sustainability and food security. A comprehensive literature review was conducted to gather information on soilless cultivation techniques, including hydroponics, aeroponics, and aquaponics. Relevant studies and reports were analyzed to assess the performance of these methods in terms of resource efficiency, crop productivity, and environmental impact. The review found that soilless cultivation techniques offer significant advantages over traditional soil-based farming, including higher crop yields, efficient water and nutrient use, and reduced environmental footprint. Hydroponic systems, in particular, have been widely adopted and have shown promising results in various crops. Additionally, soilless cultivation methods can be tailored to different environmental conditions, making them adaptable to a wide range of settings. In conclusion, soilless cultivation holds great potential for sustainable agriculture by addressing key challenges such as land and water scarcity, soil degradation, and climate change. While further research and technological advancements are needed to optimize these techniques and make them more accessible to farmers, the evidence suggests that soilless cultivation can play a significant role in achieving global food security and environmental sustainability goals.

Abstract:
This study assesses the impact of irrigating with desalinated seawater (DSW) on the profitability of greenhouse tomato in south-eastern Spain, comparing different water-quality sources in both traditional sanding cultivation and soilless hydroponic production. The assessment is based on the combination of partial crop budgeting techniques with field data from the LIFE DESEACROP Project experimental activities. Our results show that the exclusive use of DSW for tomato production increases fertilization costs by 20% in soilless systems and by 34% in traditional sanding cultivation, and water costs by 30% in soilless systems and by 48% in traditional soil cultivation. As a result, production costs increase by 5% in soilless cultivation and 3% in soil cultivation, increases that are reduced when DSW is blended with brackish water. However, the lower salinity of DSW, compared with conventional water resources in the area, increases both crop yield and profitability. Soilless cultivation would also increase tomato profitability but only if good quality water is available. The materialization of the potential benefits of soilless production requires improving water quality through the increased use of DSW. Otherwise, the traditional sanding production system, better adapted to the area’s poor soils and bad quality water, would be more profitable.

Abstract:
Traditionally grown in soil, saffron cultivation has been plagued by limited arable land, variable climate conditions, and soil-borne diseases. Phenological studies of the crop during each of its growth stages are crucial for mitigating the detrimental consequences of climate change, to which saffron crop is extremely susceptible. These also help in anticipating the future farming systems that involve crop cultivation methods, irrigation, field, and crop management. In this study, we assess the adaptability of saffron to soilless cultivation. In order to evaluate the performance of saffron grown in soilless media, a crop experiment was carried out over the course of two years, beginning in 2020 and continuing into 2021. Bulbs were planted in plastic polytunnels under two experimental treatments viz. soil-based (PS1) and soilless (PS2), supplemented with adequate nutrients. To evaluate the performance of saffron in soilless culture and to compare it with protected soil-based cultivation, saffron growth indicators were measured a total of twenty-five times at intervals of around twenty days during the entire growing period. The study of growth indices demonstrated that the PS2 (protected soilless cultivation) outperformed PS1 (protected soil-based cultivation) in terms of growth of organs (foliage, roots, mother bulbs, daughter bulbs) and biomass accumulation. In light of these findings, it has been demonstrated that soilless cultivation can be an effective method for the production of saffron.

Abstract:
The objective of this study was to evaluate the growth of micropropagated blueberry and raspberry seedlings under conventional and soilless cultivation systems. Seedlings of two blackberry cultivars (Xavante and Tupy) and two raspberry cultivars (Heritage and Fall Gold) were submitted to two cultivation systems: the conventional system and the soilless system. Under the conventional system, they were kept in polyethylene bags containing H. Decker® substrate and were irrigated with nutritive solution every 15 days. Under the soilless system, they remained in plastic flowerpots containing sand and were irrigated with nutritive solution daily. In regards to shoot length, the Xavante, Tupy, Heritage and Fall Gold cultivars showed the best results under the soilless cultivation system. As for number of lateral shoots, the Xavante, Heritage and Gold Fall showed significant results under the soilless system, unlike the cultivar Tupy, which showed better results under the conventional system. The soilless cultivation system is suitable for the development of the blackberry 'Xavante' and 'Tupy' and the raspberry 'Heritage' and 'Fall Gold' mini-cuttings

Abstract:
The cultivation of plants without using soil as a rooting medium is known as soilless farming. Depending on the requirement and type of crop, there are several soilless systems, including hydroponic, aeroponic, vertical farming, and others. The rate at which megacities are growing is worrying. As a result, urban agriculture needs to undergo a revolution in order to address the problem of food scarcity and hunger. These significant quantitative and qualitative food concerns can be solved by soilless farming in urban environments. In greenhouses and tunnels, about 3.5% of the world's crops are produced utilizing soilless, hydroponic farming methods. People who reside in deserts, the arctic, and other difficult-to-farm places can build up hydroponic farms. Since there is no soil, there are fewer insects and weeds. Vegetables, fruits, flowers, and medicinal plants are among the crops grown in soilless or hydroponic systems. Growth media is used in soilless culture methods in place of soil. As growth media, inorganic or organic substrates (barks, coconut coir, coconut soil, fleece, marc, peat) are used. Aquaponics in Nepal has a promising future because it is still in its early phases and is expected to thrive and expand well. As a result, a variety of crops are produced year, increasing income. Soilless cultures are thought of as a recently found approach to agricultural development, yet they are extremely difficult to put into practice.

Abstract:
Table grape production in soilless cultivation under a controlled environment is a promising solution that addresses many of the challenges of grapevine cultivation, such as factors affecting the quantity and quality of table grape production, cultivation cost, pest management, soil degradation, soil-borne diseases, and adaptation to climate change. However, due to limited knowledge, investigation of many factors is required to effectively implement soilless cultivation, among which are the substrate’s physical-hydraulic properties and suitability for grape production. In this context, we investigate the impact of the properties of organic (coir dust) and mineral (perlite, pumice) substrates and their blend (perlite:coir) on grapevine growth and grape physicochemical characteristics of Sugraone (Superior Seedless) and Prime cultivars. Perlite substrate was the best in qualitative and quantitative production characteristics, whereas pumice substrate proved unsuitable for soilless vine cultivation. Coir and perlite:coir substrates, due to their increased ability to retain moisture, improved plant nutrition and grape quality but delayed ripening. For effective soilless cultivation of grapevines and table grape production, substrates must have the ability to maintain sufficient but not excessive moisture, suitable for supporting physiological processes and plant nutrition, resulting in smooth growth and production.

Abstract:
Soilless cultivation represents a promising method for the future of the horticulture industry as it offers advantages such as improved quality control over the growth environment and mitigation of uncertainties related to soil, water, and nutrient availability. In this study, we aimed to investigate the effects of different environments, specifically greenhouse (GH) and open-field (OF), on the growth, phenotypic characteristics, physio-biochemical properties, qualitative parameters, and antioxidant capacity of strawberries cultivated using a soilless system. The aforementioned parameters were measured in both the GH and OF settings. Our findings revealed that the growth, yield, and morphological parameters were significantly higher in the GH environment compared to the OF. However, when considering fruit quality indices such as fruit texture firmness, fruit dry matter percentage, taste index (TSS/TA ratio), and post-harvest shelf-life, the OF cultivation method exhibited significantly superior results. Moreover, various aspects, related to plant physiology and biochemistry, antioxidant enzyme activity, total antioxidant capacity (DPPH), vitamin C content, and secondary metabolites, were found to be significantly higher in the OF environment compared to the GH. Overall, the results of our study suggest that OF soilless cultivation outperforms GH cultivation in terms of fruit quality, antioxidant capacity, and post-harvest shelf-life. Despite the observed decrease in fruit growth and yield, soilless strawberries grown in OF are likely to yield a final product of higher quality and nutritional value compared to those cultivated in a GH environment. These findings highlight the potential of OF soilless cultivation as a viable approach for strawberry production, emphasizing the importance of considering not only yield but also qualitative aspects and the nutritional value. Further exploration and optimization of soilless cultivation techniques in OF settings could contribute to the advancement of sustainable horticultural practices.

Abstract:
Soilless cultivation systems were primarily developed in response to the excessive spread of soil pathogens; however, they also allow an optimal control of plant grow, high productivity and product quality as well as very high efficiency of water and fertilizer use. At the same time, consumers remain critical towards soilless-cultivated vegetables, mainly due to the perception of these techniques as unnatural, resulting from artificial growth and consequently characterized by low quality. This mini review analyzes the evolutionary process of soilless cultivation within a vision of agriculture that supports environmental sustainability as the central theme of the discussion. Current knowledge suggests that, although apparently opposite, organic and high-tech soilless cultivation have several common or converging points in view of a sustainable use of resources on the planet. As a consequence, new policies should be oriented toward a reduction of environmental “pressure” by introducing a process certification of low environmental impact, which, together with an adequate product certification, related not only to the environmental aspect but also to product quality, can reduce the opposition of the two cultivation systems.

Abstract:
Food security and eutrophication are two issues proven to have severe impacts on both humanity and the environment. This study suggests improving the local food security by utilizing phosphorus and nitrogen, available in severe eutrophic small lakes, in local food production, thus turning eutrophication from a problem into a resource. The study theoretically experiments the possibility of using eutrophic water in a greenhouse, where hydroponics is used as a cultivation method. The eutrophic water is pumped from the lake into the greenhouse, and then to the hydroponic system, which is expected to remediate the water, returning clean water to the lake. The objective of this process is to phytoremediate eutrophic water and simultaneously, produce edible commercial plants. Finding the best matching lake and plant nitrogen to phosphorus (N:P) ratio, is of key importance to optimize the remediation process. Based on data from a literature review, edible plants N:P ratios are found lower than typical lake N:P ratios, suggesting that, in some cases, edible plants in the hydroponic system would require additional nutrients to grow optimally. Finding the best matching lake and plant N:P ratio is thought to optimize the remediation process. Matching the lake and plant N:P ratio was conducted in Python.

Abstract:
La torba è il materiale più utilizzato per i substrati impiegati nelle coltivazioni fuori suolo. Tuttavia, limitazioni relative ai costi e ad un possibile impatto ambientale dell’estrazione, nonchè alla disponibilità sul mercato da un anno all’altro, spingono la ricerca ad interessarsi a materiali alternativi. Sottoprodotti da produzioni/processi di trasformazione, possono rappresentare una fonte di materiali, con i vantaggi legati all’economia circolare. La ricerca ha riguardato fibra e midollo di cocco, compost, residui di canapa, vinacce e fibre di legno. Nella prima parte è stata eseguita una valutazione delle proprietà fisiche, chimiche e biologiche per cocco, compost, canapa e vinacce. I materiali sono poi stati testati in prove di coltivazione. Miscele di fibra e midollo di cocco hanno mostrato spiccate proprietà idrauliche (ritenzione idrica e assorbimento capillare) che aumentano all’aumentare delle percentuali di midollo (70% e oltre). Fibra e midollo di cocco, sono risultati idonei alla coltivazione di alcune specie, con crescite uguali o maggiori rispetto alla torba. Limitazioni sono state riscontrate nell’utilizzo di canapa (scarse proprietà idrauliche) e vinacce (alta conducibilità elettrica). L’idoneità delle vinacce come substrato, è però aumentata dopo il lavaggio, (riduzione concentrazione salina) e la miscelazione con materiali con migliori caratteristiche fisiche (torba e midollo di cocco). L’utilizzo di fibre di legno e compost in sostituzione totale o parziale alla torba ha modificato le proprietà fisiche dei substrati (ritenzione idrica e risalita capillare), sottolineando la necessità di un aumento della frequenza irrigua, quando tali substrati vengono impiegati per la coltivazioni ornamentali irrigate con sistemi di flusso e riflusso. I risultati suggeriscono, inoltre, che lo studio e l’uso di materiali alternativi non può prescindere da fattori quali irrigazione e nutrizione, fondamentali per il successo della coltivazione fuori suolo.<br>Nowadays, the most used constituent for growing media in soilless cultivation is still peat. However, limitations related to their extraction cost, availability on the market from one year to the next and a possible environmental impact, pushed the research to focusing on possible alternative materials. By-products from production/transformation processes could represent a source of materials for growing media, with the general advantage of a circular economy. Different by-products: coir, compost, grape marc, hemp residues and wood fibers were considered. First part of research was focused on the evaluation of main physical, chemical and biological properties of coir, green compost, hemp residues and grape marc. Then materials were tested in a series of comparative cultivation trial (i.e. basil transplant cultivation). Coir showed interesting results, some properties (i.e. water retention and capillary rise), proved to be good, in particular with high percentages of coir pith (70% or more). Coir properly supported plants growth, providing same or better results when compared to peat. Some limitation were found for hemp residues (scarce hydraulic properties) and grape marc (high electric conductivity). The grape marc suitability as substrate increased washing marc to reducing salts concentration and mixing with materials with better physical characteristics (peat and coir). Research also evaluated the totally or partially peat replacement with wood fibers and different types of compost. Wood fibers and compost in peat-based substrates modified the physical properties of the growing media such as water retention and capillary rise, suggesting the need of an increase of irrigation frequency, when alternative substrate are use for ornamental production irrigated with ebb and flow system. According to the presented results, also fertilization and water management are pivotal for successful soilless cultivation.

Thesis submitted in fulfilment of the requirements for the degree Master of Technology: Horticulture in the Faculty of Applied Sciences at the Cape Peninsula University of Technology 2013<br>This study evaluated the effects of different pH levels and supplementary phosphorous concentrations on Salvia chamelaeagnea grown in hydroponics. The treatments consisted of 12 treatments of 4 differing nutrient solutions offering: low concentration of supplementary P (control), balanced concentration of supplementary P, moderate concentration of supplementary P and a high concentration of supplementary P at 3 differing pH levels. Each treatment was replicated 10 times. The objectives of this study were to asses the effect of supplementary phosphorous concentrations and 3 different pH levels on the growth, development and chlorophyll responses of Salvia chamelaeagnea grown hydroponically. Growth and development was recorded by measuring weekly heights, numbers of basal shoots, stem diameters and the number of branches, while root length and wet and dry weights of roots and shoots were measured post harvest. Chlorophyll responses were recorded by measuring weekly SPAD-502 measurements while post harvest DMSO analysis of chlorophyll A, B and total chlorophyll were recorded along with nutrient uptake levels of N, P,K, Ca, Mg, Na, Mn, Fe, Cu, Zn and B in the plant leaves. This study has shown that the use of a hydroponic nutrient system offering a moderate concentration of supplementary P at a pH level of 4 significantly influences the growth and development of Salvia chamelaeagnea grown in hydroponics. Plants treated with a pH level of 4 generally produced higher wet and dry shoot weights, root lengths, stem diameters, basal shoot numbers, branch numbers, and plant heights than that of the control and all treatments delivering nutrients at a pH level of 6 and 8. Although no one treatment offering supplementary P produced consistently high results, in most cases all the plants receiving supplementary P at a pH level of 4 outperformed the pH 6 and pH 8 treatments receiving the same amount of supplementary P. This indicates that at a pH level of 4 the mineral nutrient availability of a nutrient solution is at an adequate level for the growth and development of Salvia chamelaeagnea. Furthering studies into the effects of arbuscular mycorrhiza on the uptake of mineral nutrients, root morphology and growth and development are recommended.

La optimización de la nutrición de los cultivos esw vital para evitar estreses y obtener altos rendimientos y calidades de los productos hortícolas. Los sistemas de cultivo sin suelo son interesantes porque permiten el manejo de los diferentes factores que afectan a la nutrición vegetal, como la composición y concentración de la solución nutritiva o la temperatura de dicha solución. En esta tesis, se ha estudiado el manejo de algunos de estos factores con la finalidad de optimizar la nutrición de plantas de rosal cultivadas para la producción de flor cortada. Este objetivo general ha sido tratado en tres capítulos. En el Capítulo 3 se expone el estudio de los factores que afectan a la absorción diaria de agua y nutrientes por las plantas de rosal. Cinco modelos de absorción mineral (nitratos, fosfatos, potasio, calcio y magnesio) y uno de absorción hídrica fueron desarrollados. El interés de estos modelos reside en la posibilidad de su aplicación en condiciones reales de producción debido a que fueron desarrollados con datos de más de un año de cultivo, y porque incluyen algunas de las prácticas más comunes en la producción de rosas para flor cortada como la renovación de tallos arqueados, el uso de malla de sombreo o la sincronización del desarrollo de los tallos florales para su cosecha en determinadas fechas. Además, otras variables independientes incluidas en los modelos fueron la concentración de la solución nutritiva, el déficit de presión de vapor, la intgegral de la radiación dentro del invernadero, la temperatura del aire y de la solución, la producción de tallos florales o factores internos desconocidos. Los modelos de absorción mineral también integraron el efecto de la absorción hídrica. El Capítulo 4 tiene como objetivo evaluar la tolerancia o sensibilidad de las plantas de rosal a la baja temperatura de la solución nutritiva mediante el estudio de su efecto sobre parámetros fisiológicos.<br>Gorbe Sánchez, E.

Orientador: Arthur Bernardes Cecílio Filho<br>Banca: Leila Trevizan Braz<br>Banca: Max José de Araújo Faria Júnior<br>Resumo: Foi conduzido um experimento em sistema hidropônico-NFT no período de setembro a novembro de 2001, na FCAV-UNESP, Jaboticabal-SP, situada a 21°15'22" S, 48°18'48" W, e altitude de 595 m. Foi utilizado o delineamento experimental de blocos casualizados, em parcelas subdivididas, com quatro repetições. Os fatores avaliados foram concentrações de nitrogênio na solução nutritiva (110, 165, 220 e 275 mg N.L-1) que constituíram as parcelas, e quatro cultivares de almeirão (Pão de Açúcar, Folha Larga, Precoce de Trieste e Catalonha), que constituíram as subparcelas. O experimento teve como objetivo avaliar o efeito da concentração de nitrogênio na solução nutritiva sobre o acúmulo de nitrato e sobre a produtividade de cultivares de almeirão em cultivo hidropônico-NFT. Foram observadas diferenças entre as cultivares quanto ao acúmulo de nitrato. O aumento de nitrato na solução nutritiva aumentou os teores de nitrato em todas as cultivares. Estes teores, foram significativamente reduzidos quando são adotadas concentrações de nitrogênio na solução nutritiva para obter-se 90 % da produção máxima das cultivares, sendo a cultivar Catalonha a que maior teor (1.752 mg NO3-) apresentou nesta condição. A cultivar Pão de Açúcar apresentou a maior produtividade (5,5 kg m-2). A concentração de nitrogênio na solução nutritiva para 90 % da produtividade máxima das cultivares Pão de Açúcar, Folha Larga, Precoce de Trieste e Catalonha foram respectivamente de 110, 151, 117 e 168 mg L-1, representando redução de 30 a 40 % nas concentrações de nitrogênio requeridas para obter as máximas produtividades.<br>Abstract: An experiment was carried in hydroponic system-NFT from September to November of 2001, at FCAV-UNESP in Jaboticabal-SP, located 21°15'22" S, 48°18'48" W and 595 meter high. The experiment was cropped in randomized blocks design, in split-plot scheme and four replications. Nitrogen concentration in nutrient solution (110, 165, 220 and 275 mg N.L-1) and four chicory cultivars (Pão de Açúcar, Folha Larga, Precoce de Trieste, Catalonha) were the studied factors. The objective this work was to evaluate the effect of nitrogen concentration in nutrient solution on nitrate contents and productivity in chicory cultivars under hydroponic system-NFT. It was observed that differences between cultivars on nitrate accumulation. The increase on nitrogen in nutritive solution promoved bigger concentrations of nitrate in all cultivars. This concentrations was reduced when are used nitrogen concentrations in nutrient solution to obtain 90 % of maxim production cultivars. Bigger concentration of nitrate was observed cultivar Catalonha (1.752 mg NO3-). Bigger productivity was observed cultivar Pão de Açúcar (5,5 kg m-2). The nitrogen concentration in nutrient solution to 90 % of maxim productivity cultivars Pão de Açúcar, Folha Larga, Precoce de Trieste e Catalonha was respectively 110, 151, 117 e 168 mg L-1, represented reduction of 30-40 % in nitrogen concentrations required to obtain maxim productivity.<br>Mestre

With the advancement of cultivation techniques, coupled with increasing demand for quality vegetables all year round, It has invested in farming alternatives, such as hydroponics which is a technology for growing plants in nutrient solution, with or without the use of substrate, in a protected environment, allowing the planting of the same species all year, and more efficient use of water and fertilizers. However, information on the nutrient solutions are still widespread, with the need for studies adapted to local conditions and the wide range of existing cultivars. The objective of this work was to study the behavior of Galia melon (Hybrid ‘Babilônia RZ F1) grown in coconut fiber and irrigated with nutrient solutions of different concentratations. The design was a randomized blocks, with five replications and five treatments, which correspond to different macronutrients in the nutrient solution, based on the recommended solution for Furlani et al. (1999), which was considered 100% concentration (C1). Getting other treatments so determined: C2=75%; C3=50%; C4=25% e C5=12,5%. From 15 days after transplanting , the analyzes of growth and nutrient absorption were performed by collecting plants from each plot , in periods of 15, 30 , 45 and 60 days after transplanting. The concentration C3 (50%) provided higher dry matter production of shoots as well as leaf area for the muskmelon. The shoot absolute growth rate showed different trends for concentrations, however C3 (50%) concentration showed the best results. The relative growth rate of shoot and the net assimilation of shoot rate tended to decrease with time for all concentrations. The nutrient uptake by following order, K > N > P, independely of the concentration of the nutrient solution, however, the concentration of C1 (100%) showed the highest levels of N, P and K in the leaves. Considering the productivity, the highest yield was obtained at a concentration of 47% of macronutrients in the nutrient solution<br>Nos últimos anos vem crescendo o cultivo dos melões rendilhados do tipo Gália, que apresentam um sabor realçado e ótimo aspecto visual. Com o avanço das técnicas de cultivo, associadas a crescente exigência por hortaliças de qualidade durante todo o ano, tem-se investido em alternativas de cultivo, dente estas, o cultivo hidropônico que é uma tecnologia para o cultivo de plantas em solução nutritiva, com ou sem o uso de substrato em ambiente protegido, o que permite o plantio da mesma espécie o ano todo, e com maior eficiência do uso de água e fertilizantes. Porém, as informações sobre as soluções nutritivas ainda são muito generalizadas, havendo a necessidade de estudos adaptados às condições locais e a grande variedade de cultivares existente. O objetivo deste trabalho foi estudar o comportamento do melão (Cucumis melo L., tipo Gália, híbrido Babilônia RZ F1), cultivado em fibra de coco e irrigado com soluções nutritivas de diferentes concentrações. O delineamento foi o de blocos casualizados, com cinco repetições e cinco tratamentos, que corresponderam a diferentes macronutrientes na solução nutritiva, tomando como base a solução recomendada por Furlani et al. (1999), que foi considerada a concentração de 100% (C1). Ficando os demais tratamentos assim determinados: C2=75%; C3=50%; C4=25% e C5=12,5%. A partir dos 15 dias após o transplantio, foram realizadas as análises de crescimento e absorção de nutrientes, através da coleta de plantas de cada parcela, nos períodos de 15, 30, 45 e 60 dias após o transplantio. A concentração C3 (50%) proporcionou maior produção de matéria seca da parte aérea, como também de área foliar para o meloeiro. A taxa de crescimento absoluto da parte aérea apresentou diferentes tendências para as concentrações, sendo que a concentração C3 (50%) apresentou os melhores resultados. A taxa de crescimento relativo da parte aérea e a taxa de assimilação líquida da parte aérea tenderam a diminuir com tempo para todas as concentrações. A absorção foliar dos nutrientes no meloeiro seguiu ordem, K > N > P, independentemente da concentração da solução nutritiva, sendo que a concentração C1 (100%) apresentou os maiores teores de N, P e K nas folhas do meloeiro. Considerando a produtividade, o maior rendimento foi obtido na concentração de 47% de macronutrientes na solução nutritiva<br>2016-11-10

Essas melancias quando conduzidas em ambiente protegido, requerem sistema de condução na vertical e manejo de plantas para garantir elevada produtividade por área e frutos de qualidade. Com base nisso, esse trabalho teve por objetivos avaliar o desempenho de híbridos comerciais de minimelancia em diferentes espaçamentos, orientação do crescimento, e número de plantas. Para isso, foram conduzidos dois experimentos, cultivados sob ambiente protegido em substrato de fibra da casca de coco, com fertirrigação. A primeira etapa foi instalada utilizando o delineamento experimental de blocos ao acaso, em esquema fatorial 5 x 3, com quatro repetições. Os fatores avaliados foram: cinco híbridos de minimelancia (‘Beni Kodama’; ‘Ki Kodama’; ‘Smile’; ‘New Kodama’; e ‘Beni Makura’) e três espaçamentos entre plantas (E1= 0,35; E2= 0,50; E3=0,65). A segunda etapa foi conduzida utilizando o híbrido ‘Smile’ no delineamento experimental de blocos ao acaso, esquema fatorial 2 x 2, com oito repetições. O primeiro fator foi constituído de número de hastes por planta (1 e 2 duas hastes), e o segundo fator foi composto de número de plantas por vaso (1 e 2 plantas). Em ambas as etapas avaliaram-se características de produção, qualidade, assim como, parâmetros fisiológicos da planta. Na etapa 1 não houve interação significativa entre os fatores avaliados (híbridos e espaçamentos). Para híbridos é possível observar que houve diferença significativa apenas para massa fresca de frutos, onde ‘Smile’ apresentou melhor desempenho. Enquanto que para o fator espaçamento houveram diferenças, sendo que, espaçamentos maiores (0,50 m e 0,65 m) proporcionaram maior massa fresca dos frutos, área foliar, firmeza de frutos, diâmetros e percentual de frutos extragrandes. Já as maiores densidades (0,35 m) aumentaram a produtividade total e o índice de área foliar. Para a etapa 2 foi possível observar interação entre o manejo de hastes e o número de plantas/vaso, nas características de área foliar, índice de área foliar, massa seca da haste, massa de frutos, produtividade total, sólidos solúveis e percentual de frutos grandes. Os tratamentos conduzidos com duas hastes e uma planta/vaso proporcionaram altas produtividades sem prejudicar a qualidade dos frutos, tornando-se viável ao produtor. Dessa forma, recomendase o cultivo dos híbridos avaliados, no espaçamento de 0,50 m entre plantas, em fibra da casca de coco, aliado ao manejo de uma planta/vaso conduzida com duas hastes.<br>In recent years, it has highlighted the group of smaller watermelons, one to three kilos, called minimelancias. These watermelons when conducted in a protected cultivation, require training system vertically and management plans to ensure high productivity per area and fruit quality. Based on this, this study aimed to evaluate the performance of commercial hybrid minimelancia in different spacings, growth orientation, and number of plants. For this, two experiments were conducted, cultivated under protected environment in fiber substrate of coconut shell, with fertigation. The first stage was installed using the experimental design of randomized blocks in a factorial 5 x 3, with four replications. The factors evaluated were: five hybrids of minimelancia (‘Beni Kodama’, ‘Ki Kodama’, ‘Smile’, ‘New Kodama’, and ‘Beni Makura’) and three spacings between plants (E1 = 0.35; E2 = 0.50; E3 = 0.65). The second stage was conducted using the hybrid ‘Smile’ in the experimental design of randomized, factorial 2 x 2 with eight repetitions. The first factor is constituted by the number of stems per plant (stems 1 and 2) and the second factor consisting of the number of plants per pot (plants 1 and 2). In both stages were evaluated production characteristics, quality, as well as physiological parameters of the plant. In step 1, there was no significant interaction between the factors evaluated (hybrid and spacings). For hybrids is observed that there was a significant difference only for fresh fruit mass where ‘Smile’ performed better. While for spacings there were differences, and that greater spacing (0.50 m and 0.65 m) provided higher fresh fruit weight, leaf area, fruit firmness, diameter and percentage of oversized fruit. Already the highest densities (0.35 m) increased total productivity and the leaf area index. For step 2 was observed interaction between the management stems and the number of plants/pot, the leaf area characteristics, leaf area index, dry mass of the stem, fruit mass, total soluble solids and fruit percentage big ones. The treatments conducted with two stems and a plant/pot provided high yields without harming the quality of the fruit, making it viable for the producer. Thus, it is recommended the cultivation of hybrids, spaced 0.50 m between plants in coconut fiber shell, together with the management of a plant/vessel conducted with two stems.<br>FAPESP: 2013/05587-0

Desta forma, com o objetivo de avaliar a influência de concentrações de nitrogênio (N) e potássio (K) em cada fase fenológica (vegetativa e reprodutiva) do meloeiro e obter a melhor relação N:K para cada uma delas, um experimento foi conduzido em casa de vegetação, em sistema hidropônico. Na primeira fase, foram avaliadas quatro concentrações de N (8, 11, 14 e 17 mmol L-1) e duas concentrações de K (4 e 5 mmol L-1), em delineamento experimental de blocos ao acaso, esquema fatorial 4x2, com cinco repetições. Na segunda fase, em esquema fatorial 2x2, foram avaliadas as combinações das duas concentrações de N que geraram as melhores características na fase anterior (maior área foliar, altura de planta e número de folhas) e duas concentrações de K (4,5 e 9,0 mmol L-1). Com base nas características de crescimento, a melhor relação N:K para a fase vegetativa foi a de 17:5 mmol L-1. O aumento das concentrações de N na fase vegetativa promoveu o aumento dos teores foliares de N, P e S e a redução de K, Ca e Mg. As concentrações de N e K não influenciaram a área foliar, produtividade e qualidade dos frutos do meloeiro, e assim considerou-se 14:4,5 mmol L-1 como a melhor relação N:K para a fase reprodutiva.<br>The correct establishment and balancing of the N:K ratio for each phenological growth stage of melon is essential to maximize the plant growth and development and avoid nutritional disorders. Thus, in order to evaluate the influence of nitrogen (N) and potassium (K) concentrations in each phenological growth stage (vegetative and reproductive) of melon plants and obtain the best N:K ratio for each of them, an experiment was carried out in a greenhouse, in a hydroponic system. In the first stage, four N concentrations (8, 11, 14, and 17 mmol L-1) and two K concentrations (4 and 5 mmol L-1) were evaluated. The experimental design adopted was a randomized block in a 4x2 factorial scheme with five replicates. In the second stage, in a 2x2 factorial scheme, the combination of the two N concentrations which generated the best characteristics in the previous stage (higher leaf area, plant height and number of leaves) and two K concentrations (4.5 and 9.0 mmol L-1) were evaluated. Based on the growth characteristics, the best N:K ratio for the vegetative stage was 17: 5 mmol L-1. The increase of N concentrations in the vegetative stage promoted the increase of leaf N, P, and S content and the decrease of K, Ca and Mg. The N and K concentrations did not influence the leaf area, yield and fruit quality, so 14:4.5 mmol L-1 was considered as the best N: K ratio for the reproductive stage.

Uma dieta deficiente neste mineral resulta na maior suscetibilidade a uma série de doenças, dentre elas câncer, hipertireoidismo e doenças cardíacas. Nesse contexto, a biofortificação de alimentos é uma alternativa promissora para a inserção do Se na alimentação humana. Assim, objetivou-se avaliar o efeito de doses de Se no crescimento, produção e biofortificação da rúcula. Plantas de rúcula foram cultivadas em ambiente protegido no sistema hidropônico. Foram avaliadas sete concentrações de Se (0, 10, 20, 30, 40, 50 e 60 µmol L-1), utilizando-se o selenato de sódio como fonte de Se. O número de folhas, área foliar, altura, massa fresca e seca da parte aérea, massa seca da raiz e produtividade foram influenciados pelas concentrações de Se. Os melhores resultados foram obtidos entre as concentrações 20 a 29 µmol L-1 de Se. Os teores de enxofre (S) e potássio (K) aumentaram linearmente com incremento no fornecimento de Se. Constatou-se a biofortificação agronômica da rúcula, pois o aumento da concentração de Se na solução nutritiva resultou em aumento no teor deste elemento na planta. Os tratamentos com o fornecimento de Se na solução nutritiva proporcionaram rúculas com teores que variaram de 598,96 a 1437,56 µg kg-1 de Se, em relação às plantas cultivadas em solução nutritiva sem Se que apresentaram 167,84 µg kg-1 de Se.<br>Selenium (Se) is an essential micronutrient for humans and animals. However, food often presents low content of this micronutrient, which is resulted mainly due to the low content of Se in the soil. The insufficient consumption of this mineral can increase the susceptibility to several diseases, including cancer, hyperthyroidism and heart disease. In this context, the biofortification of food is a promising alternative for Se insertion into the human diet. The objective of this study was to evaluate the effect of Se doses on the growth, production, and biofortification of rocket plants. Rocket plants were grown in a protected environment in the hydroponic system. Seven concentrations of Se (0,10, 20, 30, 40, 50 and 60 μmol L-1) were evaluated. Sodium selenate was used as a source of Se. The number of leaves, leaf area, height, fresh and dry shoot mass, root dry mass and productivity were influenced by the concentrations of Se. The best results were obtained between the concentrations 20 to 29 μmol L-1 of Se. With the supply of Se was possibly observed a linear increase in the sulfur (S) and potassium (K) contents. Agronomic biofortification of rocket plants was verified since the increase of the Se concentration in the nutritive solution resulted in an increase in the content of this element in the plant. Treatments with the supply of Se in the nutrient solution provided rocket plants ranging from 598.96 to 1437.56 μg kg-1 of Se, in relation to plants grown in nutrient solution without Se that presented 167,84 μg kg-1 Se.

Abstract:
The research presented in this article reflects on the theme of vegetables byproducts as a material to encourage the consumption of plant-based food in a sustainable perspective. We present a case study of cultivation of tomatoes optimized for the synthesis of bioactives such as polyphenols, which usually concentrate in the peel and are normally discarded during industrial and domestic processing. It is estimated that the European tomato industry produces more than 200,000 tonnes of waste - peels and seeds - annually, which constitute an environmental problem and an economic cost. Currently, industrial tomato waste is used in the production of animal feed and biogas, with low efficiency.In our project, the feedstock produced in hydroponic and aeroponic cultivations, is transformed into food enriched with bioactive components and transformed through additive manufacturing, to offer an innovative, engaging and sustainable consumption experience. Our objective is to transform enriched tomato peels into nutritious 3D printed pasta.The development of food ingredients from sustainably sourced bio-based feedstock leverages hydroponic and aeroponic systems to grow plants under controlled conditions. Hydroponics, a soilless cultivation method, utilises nutrient-rich water solutions to precisely control the growing environment, leading to accelerated plant growth and increased yields. Similarly, aeroponics is a soilless technology that optimises efficiency by using minimal nutrient solutions and water. This method allows for even more precise nutrient delivery to plants, resulting in reduced environmental impact and energy savings. Both hydroponic and aeroponic systems enable meticulous control over various plant growth parameters, which can be adjusted to enhance the synthesis of bioactive compounds. This approach aims to boost polyphenol content by exposing plants to specific abiotic stressors, such as increased UV light, extreme temperatures, controlled drought, and moderate salt levels. These stressors stimulate polyphenol synthesis enhancing the nutritional and health benefits of the plants. Polyphenols are naturally occurring compounds present in a variety of plant-based foods. Renowned for their antioxidant and anti-inflammatory properties, polyphenols are instrumental in lowering the risk of chronic diseases such as cancer, heart disease, and diabetes. Our plant to fork process develops in different phases:1)Tomato plants are grown in hydroponic and aeroponic systems to increase polyphenol production in response to stress conditions like drought, UV exposure, and pathogen attacks, particularly in exposed plant parts like leaves and fruit peels, enhancing flavor, shelf life, and resistance. 2)Tomatoes obtained with this type of cultivation are harvested and peeled, and the peels are analyzed to measure the polyphenol content.3)The tomato peels are then dried at 45° centigrade, in total dehydration at 0° humidity for 6 hours, with a fan power of 2 on a scale of 1 to 7.4)The dry peels are then pulverized into a very fine powder and mixed with water and flour until a soft, elastic dough is obtained. The dough is obtained mixing 40 gr of tomato peels, 50 gr of semolina flour, 50 gr of durum wheat flour, 60 ml of water, 2 gr of salt, extra virgin olive oil to taste.5)The resulting dough is processed with the Foodini 3D food printer to obtain various shapes of tomato pasta that can be consumed as fresh or dry pasta. The dry pasta is obtained throgh a new drying process in two next steps using the following parameters: a) 8 hours, 12% humidity, 40°/50° temperature; b) 6 hours, total dehydration at 0° humidity, 50°/60° temperature.6)The pasta is analysed again to measure the amount of polyphenols after transformation.The project is a concrete example of a sustainable process from plant to fork to valorise food byproducts such as tomato peels enriched with bio-active components and transformed with 3D printing technologies to allow for an aesthetically attractive rendering of food with beneficial properties for health and environment.

Abstract:
Soilless crop production in protected cultivation requires optimization of many environmental and plant variables. Variables of the root zone (rhizosphere) have always been difficult to characterize but have been studied extensively. In soilless production the opportunity exists to optimize these variables in relation to crop production. The project objectives were to model the relationship between biomass production and the rhizosphere variables: temperature, dissolved oxygen concentration and water availability by characterizing potential growth and how this translates to actual growth. As part of this we sought to improve of our understanding of root growth and rhizosphere processes by generating data on the effect of rhizosphere water status, temperature and dissolved oxygen on root growth, modeling potential and actual growth and by developing and calibrating models for various physical and chemical properties in soilless production systems. In particular we sought to use calorimetry to identify potential growth of the plants in relation to these rhizosphere variables. While we did experimental work on various crops, our main model system for the mathematical modeling work was greenhouse cut-flower rose production in soil-less cultivation. In support of this, our objective was the development of a Rose crop model. Specific to this project we sought to create submodels for the rhizosphere processes, integrate these into the rose crop simulation model which we had begun developing prior to the start of this project. We also sought to verify and validate any such models and where feasible create tools that growers could be used for production management. We made significant progress with regard to the use of microcalorimetry. At both locations (Israel and US) we demonstrated that specific growth rate for root and flower stem biomass production were sensitive to dissolved oxygen. Our work also identified that it is possible to identify optimal potential growth scenarios and that for greenhouse-grown rose the optimal root zone temperature for potential growth is around 17 C (substantially lower than is common in commercial greenhouses) while flower production growth potential was indifferent to a range as wide as 17-26C in the root zone. We had several set-backs that highlighted to us the fact that work needs to be done to identify when microcalorimetric research relates to instantaneous plant responses to the environment and when it relates to plant acclimation. One outcome of this research has been our determination that irrigation technology in soilless production systems needs to explicitly include optimization of oxygen in the root zone. Simply structuring the root zone to be “well aerated” is not the most optimal approach, but rather a minimum level. Our future work will focus on implementing direct control over dissolved oxygen in the root zone of soilless production systems.
