Foliar Spraying of a Seaweed-Based Biostimulant in Soybean

et al. 2021

Biostimulants currently available on the market include those containing seaweed extract. There is sufficient scientific evidence to conclude that applying biostimulants to agricultural crops can positively impact plant growth and yield. However, results differ between plants species and environmental conditions. As such, the present study aimed to assess the effects of doses and application times of a biostimulant based on seaweed (Ecklonia maxima) extract on the morphology and yield of soybean crops. The experiment was conducted in a field in the municipality of Uberaba, Minas Gerais state (MG), Brazil, in dystrophic red latosol. A randomized block design was used, with four repetitions, in a 3 x 5 factorial scheme consisting of three application times (phenological growth stages: V4, R1 and V4+R1) and five doses of foliar -applied biostimulant (0, 250, 500, 750 and 1000 mL ha-1). In general, biostimulant application influenced the number of branches, nodes, flowers, and pods on the soybean plants and, consequently, crop yield. A dose of 607 mL ha-1 promoted a 6.1% greater grain yield (5379 kg ha-1) than that obtained without biostimulant spraying (5070 kg ha-1). Application in stage R1 resulted in plants with more flowers and pods.

“…O manejo da irrigação por TENS proporcionou melhores resultados que por PM, para as variáveis NVP e NGV (Tabela 2), isso pode estar relacionado a maior disponibilidade de água deste manejo, principalmente entre os estádios fenológicos R7 e R8, onde o PM na comparação com TENS (Figura 4), proporcionou momentos em que a AD ficou abaixo da AFD, podendo ter influenciado diretamente nessas variáveis, já que restrições hídricas podem reduzir parâmetros relacionados a produtividade (Bastos et al, 2016).…”

Entre os fatores que influenciam na produtividade do feijoeiro, a precipitação e a nutrição são consideradas limitantes. O objetivo deste trabalho foi avaliar o manejo da irrigação, adubação nitrogenada e a inoculação de sementes, no feijoeiro de inverno, em Aquidauana - MS. O trabalho foi realizado na área experimental da Universidade Estadual de Mato Grosso do Sul, utilizando a cultivar TAA Dama com semeadura em 24 de maio de 2018. O delineamento experimental foi em blocos casualizados, em esquema de parcelas subsubdivididas, com quatro repetições. As parcelas foram os manejos de irrigação Penman-Monteith e tensiometria. As subparcelas foram com e sem inoculação de Rhizobium tropici semia 4077 e, nas subsubparcelas, foram empregadas as doses de nitrogênio em cobertura (50, 100, 150 e 200 kg ha-1 e um com ausência de nitrogênio). Foram avaliados o número e massa seca de nódulos, número de vagens por planta, massa média de 100 grãos, número de grãos por vagens, produtividade de grãos, eficiência no uso da água. Maiores doses de adubação nitrogenada em cobertura proporcionam maiores produtividades de grãos e eficiência no uso da água pelo feijoeiro. A presença ou ausência de inoculação não influencia na produtividade de grãos do feijoeiro irrigado.

“…The common bean crop (Phaseolus vulgaris L.) is one of the most traditional foods, with significant social and economic importance, moreover, is the most important crop legume for human consumption, accounting for 50% of the grain legumes consumed worldwide (Bastos et al, 2016;Ayra et al, 2018). Brazil stands out as the largest producer and consumer of beans in the world (Bastos et al, 2016).…”

When it is said about quality and quantity of water supplied through irrigation, for common bean cultivation, it is considered sensitive to water and saline stress. The objective of this work was to evaluate the biomass accumulation and growth of common bean plants (Phaseolus vulgaris L.) subjected to irrigation with different water depths, using water with different electrical conductivities. The experiment was carried out in pots under a protected environment located in an experimental area of the Federal Institute of Goiás, Rio Verde Campus, in the city of Rio Verde, Goiás. The design was a randomized complete block design in a 4 × 2 factorial scheme with three replications. 25, 50, 75 and 100% of the evapotranspiration of the crop, and two types of electrical conductivity of irrigation water equal to 0.6 and 3.0 dS m-1. All variables were analyzed using the SISVAR® software, whose mean values for the electrical conductivity treatments were compared by Tukey test at 0.05% probability and water replacement by regression analysis, when significant. The use of irrigation water with electrical conductivity of 3 dS m-1 reduces plant height, number of green leaves and stem diameter at 35 days after sowing, thus reducing dry biomass accumulation and aerial part water accumulation at 20 and 70 days after sowing. The deleterious effects under the dry mass of the aerial part at 70 days after sowing, when using an electrical conductivity of 3 dS m-1, are accentuated by the increase of the water dephts.
