Deficit irrigation is applied to several agricultural crops as a water-saving strategy. The tomato plant sensitive water stress; however, integration with biostimulant applications, based on seaweed extracts, could be strategy for plants adapting this abiotic condition. objective of study was evaluate agronomic and quality aspects cultivated under deficit combined Ascophyllum nodosum extract (ANE) application. experiment conducted using completely randomized design two replacement levels, 70...
Seaweed extracts have several functions in agriculture due to their composition that is rich nutrients, plant hormones, and bioactive substances. It a natural product used as biostimulant especially promote the growth development of plants tolerance environmental stresses. The objective this study was analyze response containing seaweed extract derived from Ascophyllum nodosum cultivation tomato eggplant seedlings, analyzing physiological parameters two different regions Brazil. Cherry were...
The use of magnetizers for the treatment irrigation water can be used in agriculture as an alternative to increase growth and yield several crops. objective this study was evaluate effect different depths magnetic on eggplant crop cultivated protected environment. carried out two experiments, first one, design completely randomized with four replications factors: (50, 75 100% ETc) qualities (water treated by without treatment). In second five replicates (75 experiment ignored 50% ETc order...

O conhecimento referente a demanda hídrica da cultura, assim como compreensão de seu desenvolvimento vegetativo é base para qualquer pesquisa científica agronômica. presente trabalho teve por objetivo determinar evapotranspiração, coeficiente taxa crescimento do fruto, caule e atividades fotossintéticas meloeiro. experimento foi conduzido em ambiente protegido no Centro Técnico Irrigação (CTI) Universidade Estadual Maringá (UEM), Maringá-Pr. híbrido utilizado o melão Cantaloupe Torreon...
Water management has a direct impact on plant development, and under deficit conditions, it often results in reduced yields. Silicon (Si), however, the potential to alleviate stress enhance performance unfavorable conditions. This study aimed analyze of tomato plants cultivated different water replacement depths forms silicon application. The experiment was laid out completely randomized design with 2 × 4 factorial arrangement represented by two (60% 100% crop evapotranspiration - ETc) four...
Determining the need for water, as well crop coefficients, is essential information management of irrigation and consequently efficiency in use water resources. The study aimed to determine evapotranspiration culture coefficients lettuce radish a monoculture system consortium protected environment. cultivar used was Vanda hybrid 19 used. reference estimated by Penman-Monteith method using data from automatic weather station cultures determined direct lysimeters constant table. demand...
The study aimed to analyze the effect of silicon application on tomato crops subjected different water management conditions. experiment was conducted in a completely randomized design with two replacement conditions (60 and 100% crop evapotranspiration - ETc), four forms (no application, full-dose soil split foliar application) replicates. When plants were reproductive stage, gas exchange analysis performed periods (critical period before after replacement). photosynthesis rates, internal...
AbstractPhotosynthesis is the most important biochemical process that takes place in plants and chlorophyll main pigment involved it. Current destructive methods for determining content are accurate, but time-consuming relatively expensive. The SPAD (Soil Plant Analysis Development) a portable meter provides an instant nondestructive reading of green color leaves. As source vitamins antioxidants such as C, carotenoids fiber content, lettuce (Lactuca sativa L.) plays crucial role human...
The analysis of non-destructive variables in plants, such as the SPAD index, shows a growing trend adoption field. However, it is necessary to determine comparative reference standards, aiming assist interpretation results obtained field and making decisions about management be adopted. study aimed propose levels index oregano leaves based on yield crop. experiment was conducted protected environment, randomized blocks design adopted with four replications 6 x 4 factorial scheme: six water...
A clorofila, molécula responsável pela atividade fotossintética das plantas, pode ser quantificada por métodos diretos e indiretos. O objetivo do estudo foi relacionar os resultados conteúdo de clorofila obtidos diferentes determinação em folhas quiabo. Foi estimado o através índice SPAD (não-destrutivo) da extração dos pigmentos foliares com acetona (destrutivo). As análises foram realizadas quiabo (cultivar Santa Cruz 47) terço médio plantas no estágio reprodutivo coloração variando...
ABSTRACT Vegetables intercropping of results in a better use natural resources, water, light, and nutrients, when properly managed. The objective this work was to evaluate the performance lettuce radish single crop systems under different irrigation water depths. experiment conducted protected environment at State University Maringá, Paraná, Brazil. A randomized block experimental design used 4×2 factorial arrangement, with four replications. first factor consisted depths (60%, 80%, 100%,...
