Resumo: | Biofertilizers based on seaweed extract are a source of nutrients that can replace conventional synthetic fertilizers, allowing their use in organic agriculture. The objective of this research was to evaluate the effect of Ascophyllum nodosum (L.) Le Jolis seaweed extract on tomato (Lycopersicon esculentum) yield and vegetative development. The experiment was carried out under protected cultivation and in the field, using the Piccolo F1 cultivar. The experimental design was completely randomized in 5 × 2 × 5 factorial arrangement (five combinations of doses and frequency of seaweed extract application; two environments: greenhouse and field, with five assessment dates) for the variables: stem diameter, average number of leaves and relative chlorophyll content. For the other variables, a 5 × 2 factorial design was used (five combinations of doses and frequency of seaweed extract application; two environments); the following variables were evaluated: stem diameter, leaf relative chlorophyll content, number of leaves, average fruit weight, number of fruits, longitudinal and transverse fruit diameter, rachis length and average yield. It was possible to verify that the 0.3% seaweed extract dose under protected cultivation and in the field, applied every two weeks, increased the tomato yield, without altering the characteristics of fruits and vegetative growth. |

Biofertilizantes a base de extrato de alga marinha podem substituir os fertilizantes sintéticos convencionais permitindo sua utilização na agricultura orgânica. O objetivo foi avaliar o efeito do extrato de alga Ascophyllum nodosum (L.) Le Jolis no desenvolvimento vegetativo e na produção do tomateiro (Lycopersicon esculentum). O experimento foi conduzido em ambiente protegido e a campo utilizando-se a cultivar Piccolo F1. O delineamento experimental foi o inteiramente casualizado com quatro repetições em arranjo fatorial 5 × 2 × 5 (cinco combinações de doses e frequências de aplicação de extrato de alga, dois ambientes: cultivo protegido e campo e 5 datas de avaliação) para as variáveis diâmetro médio do caule, número médio de folhas, teor relativo de clorofila, já para as demais variáveis o delineamento foi em esquema fatorial 5 × 2 (cinco combinações de doses e frequências de aplicação de extrato de alga, dois ambientes). Foram avaliadas as seguintes variáveis: diâmetro do caule, teor relativo de clorofila da folha, número de folhas, massa média dos frutos, número de frutos, diâmetro longitudinal e transversal dos frutos, comprimento da ráquis e produção média. Verificou-se que a dose de 0,3% de extrato de alga em cultivo protegido e a campo, aplicados a cada quinze dias proporcionou o aumento da produção, sem alterar as características dos frutos e o crescimento vegetativo da planta.
