The influence of calyx maturation stage and types of packaging on the germinati...
Santana, Weslley Rosário; Silva, Érica Duarte; Oliosi, Gleison; Altoé, Jalille Amim; de Oliveira, Jeniffer Ribeiro; Sesquim, Larissa AndreataStudies of the optimum harvest time for obtaining seeds for the sexual propagation of the goldenberry are essential to help maintain seed viability. This study aimed to determine the optimum harvest time for the goldenberry based on the calyx maturation stage and viability of stored seeds. The design was completely randomized a in factorial design (5 x 3), with three replications. The treatments consisted of a ...
Agronomic performance and genetic divergence between genotypes of Manihot escul...
Giles, João António D.; Oliosi, Gleison; Rodrigues, Weverton P.; Braun, Heder; Ribeiro-Barros, Ana I.; Partelli, Fábio I.The morphoagronomic characterization of 12 genotypes of M. esculenta was performed during the 2013/2014 and 2014/2015 crop years. The 12 genotypes were planted in a randomized block design, with four replicates per genotype. Number of tuberous roots per plant, weight of tuberous roots, root yield, total plant weight, harvest index, plant height, height of first branch, number of shoots, stem diameter, number of...
Ammonia volatilisation from coated urea in conilon coffee crop
Rodrigues, José de Oliveira; Partelli, Fábio Luiz; Pires, Fábio Ribeiro; Oliosi, Gleison; Espindula, Marcelo Curitiba; Monte, José AntônioAmong the sources of nitrogen (N) used in agriculture urea is the most widely used fertilizer in Brazil. However, this source presents problems with the application on the soil surface due to N losses by NH3 volatilisation, resulting from the action of the enzyme urease. This study aimed to determine the losses of nitrogen (N) by Ammonia volatilisation and yield of Conilon coffee plants fertilized with protecte...
Chlorophyll a fluorescence transient and vegetative growth in conilon coffee un...
Oliosi, Gleison; Rodrigues, José de Oliveira; Falqueto, Antelmo Ralph; Pires, Fábio Ribeiro; Monte, José Antônio; Partelli, Fábio LuizThe use of nitrogen fertilizers is an effective resource to increase the coffee yield, so that the improvement and /or generation of new techniques that assist in the management of nitrogen fertilization are essential, as will contribute to increase nitrogen use efficiency (N). Thus, this study aimed to determine the chlorophyll a fluorescence transient and vegetative growth in Conilon coffee under different ni...
