Crescimento e produção do jambu submetido a lâminas de irrigação

Abstract

This study evaluated the effect that different irrigation depths have on the growth and crop production of jambu plants. The treatments consisted of five irrigation depths corresponding to 40%, 70%, 100%, 130% and 160% of field capacity. We used randomized blocks with four replications for the experimental design. The plot consisted of four plants in separate pots. For comparison of treatments, at 27 days after transplantation, the following variables were analyzed: plant height, stem diameter, leaf fresh matter, stalk fresh matter, root fresh matter, inflorescence fresh matter, leaf dry matter, stalk dry matter, root dry matter, inflorescence dry matter and water use efficiency. The effect of irrigation depth was significant for the analyzed variables, except for stem diameter and inflorescence dry matter. There was a quadratic behavior of the variables regarding the applied irrigation depths. The maximum values of each parameter were obtained with irrigation depths close to 100% field capacity. Although the efficiency of water use was higher for the irrigation depth of 40% field capacity, the use of irrigation depth at 100% field capacity is recommended since it provided the best answers of the variables analyzed.

Adubação orgânica na produção de massa seca e acúmulo de nutrientes em plantas de jambu

“…O jambu tem despertado o interesse da indústria farmacêutica e cosmética, devido a presença do espilantol, pois inúmeros testes comprovaram a ação antiinflamatória, analgésica e anestésica desse composto (Gaia et al, 2020). A produção para comercialização geralmente é feita em pequenas propriedades, na forma de agricultura familiar, e enfrenta diversos problemas técnicos que tornam o processo ineficiente, gerando baixas produtividade, padronização e qualidade do produto (Sampaio et al, 2018).…”
