“…As lâminas totais aplicadas por tratamento foram obtidas pelo cálculo da lâmina real necessária, levando-se em consideração as precipitações efetivas que ocorreram no período do experimento (Tabela 1). De maneira geral, o requerimento hídrico para as espécies do gênero Capsicum varia de 400 a 1.250 mm para condições de campo (Doornenbos e Kassam 2000, Azevedo et al 2015, Mashhor et al 2020 ou ambiente protegido (Chaves 2008, Paula 2008, Júnior et al, 2015. Os resultados obtidos para as lâminas de água em C. frutescens cultivadas por 301 dias nos diferentes tratamentos foi semelhante aos obtidos por Chaves (2008) e Paula (2008) para a mesma cultura, porém em ambiente protegido, onde os com valores de lâminas de 459 mm para o ciclo de 245 dias e 461 mm, num ciclo de 188 dias, respectivamente.…”

As hortaliças são culturas bastante susceptíveis às deficiências hídricas, principalmente às grandes variações do nível de água no solo, resultando num crescimento reduzido e desuniforme dos frutos. Este trabalho teve como objetivo avaliar as trocas gasosas foliares e os componentes de produção de pimentas malagueta em função de diferentes tensões de água no solo. O experimento foi conduzido no campo de horticultura da Universidade Estadual de Santa Cruz – UESC em delineamento experimental de blocos casualizados com quatro tratamentos em quatro blocos, sendo a unidade experimental composta por cinco plantas por parcela em espaçamento 1,0 x 0,6 m, num total de 80 plantas. Foram aplicados os tratamentos, quando os potenciais matriciais atingiam os valores de 5, 10, 20 e 25 kPa, para os tratamentos T1, T2, T3 e T4, respectivamente, para o tensiômetro instalados a 0,15 m de profundidade. Para a determinação das trocas gasosas foliares foi utilizado o analisador de gases por infravermelho onde foram medidos a taxa fotossintética líquida, a condutância estomática e a transpiração. A colheita foi realizada semanalmente sendo retirados os frutos de coloração avermelhada totalmente maduros e sem danos físicos. Estes foram pesados e a partir dessas informações foram analisados a massa média dos frutos e o número médio de frutos por planta. Os dados foram submetidos à análise de variância e teste de médias. A análise de trocas gasosas foliares obtidas nos tratamentos não apresentaram diferença estatística ao longo do período experimental. Além disso, não houve diferença significativa entre os tratamentos para a massa e quantidade de fruto.

“…In addition, ongoing disruptions in fertilizer production and subsequent supply chains issues driven by political issues have resulted in a marked increase in input costs, which continue to challenge food production [2]. Soilless production practices have the potential to reduce fertilizer inputs and water loss, thereby offering the means for effective and environmentally friendly production of food [3][4][5]. However, there is concern as to the sustainability of soilless/hydroponic production systems, as they depend on excessive use of synthetic fertilizers to prepare nutrient solutions [6], which may cause harm to the environment if not correctly disposed of or treated [7].…”

Nutrient Solution Electrical Conductivity Affects Yield and Growth of Sub-Irrigated Tomatoes

et al. 2023

Sub-irrigation of greenhouse crops has the potential to increase water and nutrient use efficiency; however, fertilizer salts that are not absorbed by the plants tend to accumulate in the substrate and eventually raise the substrate’s electrical conductivity (EC). The objective of this study was to determine the optimum EC of the nutrient solution in sub-irrigated tomatoes to allow maximum yield. Total fruit yield was higher in sub-irrigated plants with solutions at 2.0 dS m−1 (5105 g per plant), and it was comparable to that obtained for drip-irrigated plants (4903 g per plant); however, the yield of fruits from the second truss was 37% higher in sub-irrigated than in drip-irrigated plants when the EC was 2.0 dS m−1. In contrast, at the end of the growing season, the yield of plants sub-irrigated with nutrient solutions of 2.0 dS m−1 was the lowest, being surpassed by 37% by that of plants treated with 1.4 dS m−1. The dry weight of vegetative plant parts was reduced in sub-irrigated plants, suggesting a shift in dry mass partitioning. Our results show that with sub-irrigation, the growing season should be started using nutrient solutions with higher EC, but eventually, this EC should be decreased to maintain proper substrate EC and high yield.

“…Meanwhile, micro-irrigation techniques have high efficiency by directly flowing water into the soil (sub-irrigation). In this method, plant roots can absorb water without water loss (drainage), and the soil maintains moisture to break down the evaporation rate [4]. The water flowing in the micro-irrigation system is known as an emitter, and its design is important with the deepest parameters that are used for operation.…”

This study aimed to design and implement a subsurface irrigation system using porous emitters of various materials such as bubblegum, flannel, cotton, and spandex. It was carried out using descriptive methods, namely designing, measuring, observing, calculating, and analyzing data quantitatively. The results showed that the soil conductivity ranges from 1.0 to 3.01 cm3/hour, and the flannel material transmitter has a maximum hydraulic conductivity of 4.681 cm/hour. The largest and smallest porous irrigation discharges were found in flannel and bubblegum materials, with values of 2.4 l/hour and 0.59 l/hour, respectively. Emitter flannel had the best absorption capacity of 1.9348 l/hour, and the growth of porous emitter plants had the highest values of 228.6 cm, 158, 133, and 92 for height, leaves, flowers, and fruit. The daily water requirement in the vegetative phase was 112.15 ml/day, and the flowering stage continued to increase by 211.95 ml/day, while the fruiting stage was 176.63 ml/day. Tomato water requirement decreased to 156.96 ml/day at the ripening stage, and irrigation application one day after the vegetative, flowering, fruiting, and vegetative stages required 118.33 ml/day, 141.30 ml/day, 194.28 ml /day, and 264.93 mm/day, respectively. Furthermore, subsurface irrigation produced flannel optimally to meet the needs of plant growth, had no surface runoff and water loss due to percolation, with efficient use of water, and can reduce or prevent salinization.
