“…We expect significant differences when it comes to analyzing the leaf development in relation to shading (Llic & Fallik, 2017), nevertheless some vegetables presented different behaviors. Some studies, which were carried out by Ferreira et al (2021), on shading on jambu plants (Acmella oleracea), which is also an unconventional vegetable, showed that the shading screens had not provided significant differences for leaf area considering the evaluated varieties. The same was observed in this study.…”

Climatic factors can decisively influence the growth and productivity of agricultural crops. For unconventional vegetables, such as the Amazon chicory, the influence of sunlight on growing cycle is unknown. The aim of this study was to evaluate the influence of shading levels on the productive performance of Amazon chicory. The authors used a randomized block design, with four treatments and five replicates. The treatments were black polypropylene screens, 30, 50 and 70% shading, and cultivation at full sunlight. Vegetative development and production traits were evaluated. Correlation and principal components analysis (PCA) were performed with the aid of the computer program R. No significant difference between the shading levels for the evaluated traits was noticed. Nevertheless, the cultivation at full sunlight allowed an increase in production, compared to the 70% shading screen. A strong positive correlation between productivity, leaf fresh mass and amount of water in the shoot area was verified, with a coefficient equal to 1. Only the leaf area characteristic was poorly correlated with other traits (angle >90º). Therefore, we suggest growing the Amazon chicory both at full sunlight and under 70% shading.

“…Jambu (Acmella oleracea (L.) R. K. Jansen) is a non-conventional herbaceous vegetable with small size and branching creeping stems, belonging to the Asteraceae family. It is consumed in typical dishes of the Northern region of Brazil and used for medicinal purposes (Gusmão & Gusmão, 2013;Ferreira et al, 2021).…”

Due to the lack of specific fertilization recommendations for jambu cultivation, producers commonly usefertilizers recommended for other vegetables. This study aimed to evaluate the effect of different doses oforganic fertilizers, namely hoof and horn powder and castor bean cake, on jambu plant production under anorganic system. The experiments were conducted at the Experimental Farm of São Manuel, SP, belonging to theSchool of Agriculture (FCA) – UNESP, and at the “Estância Três Nascentes” site, located in Botucatu, SP, Brazil.Twelve treatments were evaluated, in a 2 x 6 factorial design, consisting of two organic fertilizers (castor beancake (CBC) and hoof and horn powder (HHP)) x 6 top dressing N doses (50, 75, 100, 125, 150, and 0 (controlwithout these fertilizers)). The experimental design was a randomized block with four replications. Plant height(PH), number of inflorescences (NI), the fresh weight of inflorescence (FWI), the fresh weight of vegetative parts(FWVP), and the total fresh weight (TFW) were evaluated at each location. Linear increases were observed in allcharacteristics in both locations as the fertilizer doses increased. Comparing the highest dose (150 kg ha-1 of N)with the control, increases of 109%, 251%, 218%, 283%, and 227% were obtained at the farm in São Manuel, and69%, 79%, 111%, 276%, and 118% in Botucatu, for PH, NI, FWVP, FWI, and TFW, respectively. When comparing thetwo fertilizers, HHP presented better results than CBC for most characteristics in both areas.

“…O jambu apresenta propriedades culinárias e medicinais, sendo utilizado na gastronomia (NEVES et al, 2019), na medicina popular (FERREIRA et al, 2021;OLIVEIRA BRITO et al, 2022) e como inseticida (ARAÚJO et al, 2018). Na culinária, o jambu é utilizado no prato paraense tradicional chamado tacacá, uma sopa quente que combina tucupi (caldo extraído da mandioca), camarão, goma de mandioca e jambu (HOMMA et al, 2011).…”
