Nutrient accumulation in fruits and grains of black pepper at different ripenin...
Dalazen,Jéssica Rodrigues; Valani,Gustavo Pereira; Vieira,Henrique Duarte; Ramalho,José Cochicho; Lacerda Jr,Valdemar; Romão,WandersonABSTRACT: Nutrients accumulation in plants/fruits varies according to the crop development stage and its quantification is important to determine nutrients exportation for fertilization planning and nutrient balancing. This study determined the accumulation of nutrients in different parts of Piper nigrum ‘Bragantina’ spikes harvested at two ripening stages (still-green and red-colored spikes). Assessments in se...
Soil chemical properties and nutrition of conilon coffee fertilized with molybd...
Rosado,Thiago Lopes; Freitas,Marta Simone Mendonça; Carvalho,Almy Junior Cordeiro de; Gontijo,Ivoney; Pires,André Assis; Vieira,Henrique DuarteABSTRACT Molybdenum (Mo) availability is strongly affected by soil pH, which determines the dynamics of electrical charges and the adsorption of molybdate. This study evaluated the effects of nitrogen (N) and Mo application on the chemical properties of a Latossolo Amarelo (Oxisol) and in Coffea canephora nutrition and productivity throughout two productive cycles under field conditions. The experiment was cond...
Phenomics approaches: genetic diversity and variance components in a S2 guava f...
Silva,Carla Caroline Amaral da; Vieira,Henrique Duarte; Viana,Alexandre Pio; Maitan,Mariana Quintas; Santos,Eileen AzevedoABSTRACT Guava is of great economic importance in Brazil. The development of new cultivars by obtaining inbreeding lines has been a promising option. The objective of this work was to evaluate the S2 families of Psidium guajava using seed attributes. Different characters of physiological quality of guava seeds were studied, in addition to performing digital phenotyping of characteristics of geometry, texture an...
Quality of Stylosanthes Campo Grande seeds coated with different materials
Silva,Flávio Wirlan Andrade da; Vieira,Henrique DuarteABSTRACT The seed coating technique adds value to the seeds. This technique allows changing the seed size and shape, facilitating sowing, and also the application of essential nutrients to the good development of the plant in the post-germination phases. Therefore, the objective of this work was to evaluate the physical and physiological characteristics of Stylosanthes capitata/macrocephala coated with differen...
Physical and physiological quality of seeds of Campo Grande Stylosanthes coated...
Baroni,Danilo Força; Vieira,Henrique Duarte; Silva,Flávio Wirlan Andrade da; Acha,Amanda Justino; Pires,José Inácio CoelhoABSTRACT: The binder materials used in seed coating provide adherence of the filler materials onto the seeds. Adequate concentrations of the binder promote good physical characteristics of coating while not impairing seed physiological characteristics. Thus, the objective of this study was to evaluate the type and the concentration of binder materials that allow the best physical and physiological characteristi...
Physiological responses of seeds from full-sib guava families to different subs...
Maitan,Mariana Quintas; Viana,Alexandre Pio; Vieira,Henrique Duarte; Silva,Carla Caroline Amaral da; Rodrigues,Daniele Lima; Leal,Lucas Souza da SilvaAbstract Guava is an important fruit in Brazil and worldwide. However, research has yet to advance on its breeding and seed technology, an essential factor for the development of productive genotypes with germination potential which would support the continuity of breeding programs. In search of a methodology for routine analysis testing of guava seeds under genetic control, this study examined the effect of te...
Digital image processing of coated perennial-soybean seeds and correlation with...
Acha,Amanda Justino; Vieira,Henrique DuarteAbstract: Perennial soybean (Neonotonia wightii) is a Fabaceae with potential to be used in consortium with Poaceae plants to improve pasture quality. In order to add value to perennial soybean seeds and improve their seed distribution, seeds coated with different materials in coating machine were characterized by digital image analysis and physical attributes related to physiological attributes in order to def...
Coating seeds with fertilizer: A promising technique for forage crop seeds
Baroni,Danilo Força; Vieira,Henrique DuarteABSTRACT Fertilization is not a common management practice at pasture establishment in Brazil. Seed coating technology can be a useful approach to ensure the availability of nutrients to plants during the early stages of development. Thus, the objective of this work was to investigate the incorporation of liquid fertilizer in seeds of Stylosanthes and to evaluate the effect of this technology on seed quality. M...
Soil patterns and foliar standards for two cocoa clones in the States of Espíri...
Oliveira,Marcos Góes de; Partelli,Fábio Luiz; Cavalcanti,André Cayô; Gontijo,Ivoney; Vieira,Henrique DuarteABSTRACT: The objective of this research was to establish soil patterns and foliar standards for clonal crops of cocoa CCN51 and PS1319 in the Atlantic regions within the northern Espírito Santo and southern Bahia States. Samples were collected from September to October 2015, in 45 high productive plots, being 23 plots of clone CCN51 and 22 of clone PS1319. Sufficiency ranges for soil and foliar standards were ...
Andina - first clonal cultivar of high-altitude conilon coffee
Partelli,Fábio Luiz; Golynski,Adelmo; Ferreira,Adésio; Martins,Madlles Queiroz; Mauri,Aldo Luiz; Ramalho,José Cochicho; Vieira,Henrique DuarteAbstract Andina is a conilon coffee variety originated from a selection of clones discovered by farmers. It was cultivated and evaluated for yield and plant vigor an altitude of 850m asl. Five genotypes (A1, NV2, NV8, P1 and Verdim TA), with a mean yield of 51.3 bags per hectare per year.
