“…J. F. Canjá et al (2021) According to SANTOS et al (2019), biofertilizers favor further development of cultures. Similar results regarding the effect of organic inputs on root length were reported by Mesquita et al (2012) in papaya culture and by Véras et al (2015) in cashew seedlings.…”

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.

“…En ausencia de biofertilizante (SB), los sustratos de las plántulas de maracuyá amarillas aumentaron sus CE de 0,41 a 1,50 dS m -1 en la salinidad del agua estimada de 0,5 y 4,0 dS m -1 , respectivamente (Figura 1A). Estos resultados son más bajo a los presentados por Mesquita et al (2012a), donde se encontró en los substratos de plântulas de maracuyá los valores de CE del orden de 3.28 e 4.91 dS m -1 , en el suelo sin y con aporte orgánico a 65 DAE. Este resultado se debe a la acumulación de sales en el sustrato con riegos periódicos con agua salina.…”

“…El exceso de sales en el agua de riego causa varios efectos, entre los cuales: el efecto osmótico, el desequilibrio nutricional y el efecto tóxico de los iones, particularmente el cloro y el sódio (MELO FILHO et al, 2017). Se sabe que la salinidad afecta drásticamente el crecimiento y la producción de varias frutas, incluida la fruta de la maracuyá agria (MESQUITA et al, 2012b) y fruta de la maracuyá amarillo Passiflora edulis f. flavicarpa (MESQUITA et al, 2012a;MEDEIROS et al, 2016).…”

El objetivo fue evaluar los efectos de la salinidad del agua de riego en la formación de plántulas de maracuyá amarillas utilizando biofertilizantes bovinos comunes y enriquecidos, respectivamente. En este sentido, se realizó un experimento en un invernadero, en la ubicación del Centro de Ciencias Agrícolas y de Biodiversidad CCAB / UFCA, municipio de Crato (CE), desde octubre de 2018 hasta marzo de 2019. El sustrato era material de los primeros 20 cm de un Latosol rojo-amarillo. El diseño experimental fue completamente al azar en un esquema factorial 5 × 2 × 2, con tres repeticiones, en referencia a los valores de conductividad eléctrica del agua de riego: 0,5; 1,0; 2,0; 3,0 e 4,0 dS m-1, en suelo sin y con biofertilizante común, sin y con biofertilizante químicamente enriquecidos con leche y yeso agrícola, empacado en bolsas de polietileno negro con una capacidad máxima de 5.0 kg, totalizando 60 tratamientos. Las variables estudiadas fueron: conductividad eléctrica del suelo, altura de la planta, número y área de la hoja, diámetro del tallo y raíz. El aumento en la salinidad del agua de riego afectó negativamente el comportamiento inicial de las plántulas, pero con menos intensidad en los tratamientos con biofertilizantes ricos y comunes, respectivamente.

Foliar application of biofertilizer in semi-hydroponic lettuce fertigated with saline nutrient solution

Water scarcity in the world is a problem diagnosed especially in countries with large semi-arid regions such as Brazil. Research has been conducted with a view to making use of saline waters as an input for cultivation, particularly in hydroponics, with especial focus on lettuce, the most prominent leafy vegetable in Brazil. The objective of this study was to evaluate the development of lettuce in a semi-hydroponic system fertigated with saline water and under foliar fertilization with biofertilizer. The present study was carried out in a greenhouse located in the experimental area of the Department of Environmental and Technological Sciences (DCAT) of the Federal Rural University of the Semi-Arid Region, in the municipality of Mossoró, RN, Brazil. The experimental design was a randomized complete block design, with treatments arranged in a 2 x 4 factorial scheme, with 4 replicates, two salinity levels of the water used to prepare the nutrient solution (0.5 and 3.5 dS m-1) and four biofertilizer concentrations (0, 20, 40 and 60%) applied by foliar spraying. The evaluated characteristics were: shoot diameter, stem diameter, number of leaves, fresh mass, dry mass, leaf succulence, leaf area and specific leaf area. The use of saline water to prepare the nutrient solution reduces fresh mass and dry mass production in the lettuce crop. The biofertilizer can be applied through the leaves at concentration of up to 20%, promoting greater plant growth.
