Jambu varieties performance under shading screens

The 50%-shading screen for instance provided both higher fresh weight accumulation and higher shoot water content. [...]50%-shading screen led to an increase in both productivity (Kg m-2) and yield (bunch m-2) by 46%, respectively. According to Menezes Júnior & Vieira Neto (2012), the performance of jambu depends on its adaptation to the environment and cultural practices adopted in the field. [...]for non-conventional vegetables such as jambu, studies exploiting shading screens and plant yield are quite limited. [...]this work aimed to evaluate the effect of shading screens on the agronomic performance of jambu varieties. Six plants per plot were evaluated for main branch length, by measuring along the neck to the main branch apex (expressed in centimeters); the number of inflorescences, by counting the total of inflorescence per plant; dry inflorescence weight, by drying the inflorescence in an oven at 65 ° C for 48 hours before being weighted; the number of secondary branches, by counting the total of secondary branches per plant; shoot fresh weight, by weighing the shoot (stems, leaves, and inflorescences); shoot dry weight, by drying the shoot in an oven at 65 ° C for 48 hours before being weighted; dry leaf weight, by drying the leaves in an oven at 65 ° C for 48 hours before being weighted; and shoot water content, estimated by the difference between shoot fresh weight and shoot dry weight.
