“…In the soil with chemically enriched bovine biofertilizer, root growth increased linearly from 30.40 to 45.84 cm between plants irrigated with water of 0.5 and 4.0 dS m -1 , representing a gain of 50.8%. Similar behavior was observed for root growth in oiticica (Licania rigida Benth) seedlings irrigated with saline waters (DINIZ NETO et al, 2014). The biofertilizer, through its contribution of humic substances, promoted improvements in physical attributes of the soil, mainly in structure and porosity, which resulted in higher root growth under saline conditions (ALENCAR et al, 2018).…”

“…One approach is the adoption of technologies to allow the use of brackish water in agriculture, without great losses in the quality of seedlings and crop yield. In this context, the bovine biofertilizer Vairo promotes greater root and aerial tissue growth, and greater formation of biomass, in comparison to plants without this organic input, during the formation of seedlings of several nonfruit and fruit species (DINIZ NETO et al, 2014;OLIVEIRA et al, 2017;LIMA NETO et al, 2018).…”

Water scarcity and water quality is a subject of constant debate around the world, with the accumulation of salts in water and on soils causing a negative impact on food production, man and herds, especially in the arid and semi-arid regions. The use of bovine manure biofertilizers that potentiate the use of brackish water, normally restricted in agriculture due to its salinity, has been suggested for seedling formation and crop production, including jackfruit plants. An experiment was carried out from October/2012 to February/2013, in a protected environment, at Agrarian Sciences Center, Federal University of Paraíba, Areia county, Paraíba State, Brazil, to evaluate the effects of saline water and bovine biofertilizer chemically enriched with gypsum, cow's milk and molasses. The experimental design was completely randomized, with five replications of a plant, in a factorial scheme 5 × 2, corresponding at values of electrical conductivity of the water of 0.5, 1.0, 2.0, 3.0 and 4.0 dS m-1 substrate with and without bovine biofertilizer. Measurements were made of substrate salinity, height of growth, stem diameter, length mean root, leaf area, leaf area ratio, and total dry mass (root, shoots and leaves). The biofertilizer enriched with cow's milk, sugar cane molasses and agricultural gypsum increased the salinity of the soil; however, it attenuated the negative effects of the salts during establishment of jackfruit seedlings, to 95 days after emergence. All the growth variables studied were higher for seedlings developed in substrate with bovine biofertilizer chemically enriched.

“…The other biofertilizers (quail, mixed, bovine, and crab) alleviated the salt stress for this variable. Diniz Neto et al (2014) also pointed out that the use of organic inputs as a way to mitigate the effects of salts on plants aims to increase the content of humic substances in the soil as organic matter. Souza et al (2019) found higher RDM in broad bean plants under saline stress and fertilization with bovine and caprine biofertilizer.…”

“…Quanto a MSR, apenas o biofertilizante ovino foi superior estatisticamente quando irrigado com água de baixa salinidade, enquanto para os demais biofertilizantes (codorna, misto, bovino e caranguejo) atenuaram o estresse salino para essa variável. Diniz Neto et al (2014), destacam ainda que utilização de insumos orgânicos como forma de atenuar os efeitos dos sais às plantas, visa incrementar o teor de substâncias húmicas no solo como matéria orgânica. Souza et al (2019), constataram maior MSR em plantas de fava sob estresse salino e adubação com biofertilizante bovino e caprino.…”

Zucchini culture is slightly sensitive to salinity and is among the ten vegetables of highest economic value, with characteristics of precocity and easy cultivation. These characteristics are some of the reasons for the expansion of its cultivation among small producers. Thus, the objective was to evaluate the effect of different levels of salinity in the irrigation water and biofertilizer types on the initial growth of the zucchini (Cucurbita pepo L.) culture. The experiment was carried out in the full sunlight in a randomized block design, in a 5x2 factorial arrangement. The treatments consisted of a combination of five types of biofertilizers (quail, sheep, mixed, bovine, and crab) and two salinity levels of the irrigation water (0.8 and 2.5 dS m-1), with five replicates. At 30 days after transplanting, the following variables were evaluated: electrical conductivity of the substrate, plant height, number of leaves, roots length, stem diameter, leaf area, chlorophyll content, dry mass of the aerial part, root dry mass, and total dry mass. Salt stress negatively interferes with the accumulation of zucchini plant biomass. Quail, bovine, and sheep biofertilizers are more efficient about plant height, number of leaves, and stem diameter. The sheep biofertilizer attenuates the salt stress for the dry mass of the aerial part, the root, and the total dry mass.

“…Uma alternativa utilizada para minimizar os efeitos dos sais sobre o solo e as plantas, é o uso de matéria orgânica no solo, estimulando a redução do potencial osmótico, contribuindo para a absorção de água e, atenuando o dano provocado pela salinização às plantas (DINIZ NETO et al, 2014;FREIRE et al, 2015). No entanto, ainda são escassos trabalhos com ênfase no uso de matéria orgânica como atenuante da salinidade, evidenciando assim a necessidade de pesquisas que resultem em tecnologias viáveis para os produtores; e que possam minimizar os efeitos nocivos do excesso de sais nas plantas, já que é quase obrigatória, em regiões semiáridas, a utilização de águas salinas na agricultura (FREIRE et al, 2016).…”

Crescimento de plantas de rúcula em substratos e níveis de salinidade da água de irrigação

et al. 2019

ResumoO uso de água salina na produção de hortaliças é um dos principais desafios dos produtores, visto que o estresse salino causa diminuição na produção e rendimento das culturas. Objetivou-se avaliar o crescimento de plantas de rúcula em substratos e níveis de salinidade da água de irrigação. O experimento foi conduzido em casa de vegetação, utilizando o delineamento inteiramente casualizado em arranjo fatorial 3 x 5 e com quatro repetições. Os tratamentos consistiram de três substratos (solo; húmus de minhoca + areia + solo e torta de filtro + areia + solo) e cinco níveis de condutividade elétrica (0,5, 1,5, 2,5, 3,5 e 4,5 dS m -1 ). Foram avaliadas as características: altura de plantas, número de folhas, área foliar, massa fresca e massa seca da parte aérea. A interação entre os níveis de salinidade e os substratos testadas não foi significativa para o número de folhas. Níveis crescentes de salinidade da água de irrigação, resulta na redução das características de crescimento de plantas de rúcula cultivar Apreciatta, no entanto, os substratos com adição de matéria orgânica atenuaram os efeitos nocivos da salinidade, sendo uma alternativa viável para o cultivo de plantas de rúcula em condições de salinidade. Palavras-chave: Eruca sativa; condutividade elétrica; estresse salino.
