Morphological and productive influence of harvest on coffee plants
(2019-01-01)
The harvest of coffee, manual or mechanical, causes damage to the plants in several ways. Such damage manifests negatively in the following harvest, increasing the bienniality of coffee. Therefore, the aim of this work was ...
Phytoextraction by arsenic hyperaccumulator Pteris vittata L. from six arsenic-contaminated soils: Repeated harvests and arsenic redistribution
(2008)
This greenhouse experiment evaluated arsenic removal by Pteris vittata and its effects on arsenic redistribution in soils. P. vittata grew in six arsenic-contaminated soils and its fronds were harvested and analyzed for ...
Repeatability and genotypic stability of agronomic characteristics in Panicum maximum Jacq.
(Inst Investigaciones Agropecuarias, 2019-10-01)
In experiments with selection of perennial plants, the initial performance is expected to be maintained throughout the productive life. The probability of repeating the agronomic response can be evaluated by the repeatability ...
Experimental study of the variations in the electromechanical properties of piezoelectric energy harvesters and their impact on the frequency response function
(Academic Press, 2019)
This work presents a comprehensive study of the uncertainties involved in the FrequencyResponse Function (FRF) of Piezoelectric Energy Harvesters (PEHs) based on experimentalresults. A proper experimental setup is designed ...
Repeated applications of cppu on highbush blueberry cv. Duke increase yield and enhance fruit quality at harvest and during postharvest
(INST INVESTIGACIONES AGROPECUARIAS, 2014)
Applications of N-(2-chloro-4-pyridyl)-N'-phenylurea (CPPU) can increase blueberry (Vaccinium corymbosum L.) yield and fruit size, but their impact on postharvest is unknown. We studied repeated CPPU applications effects ...
Number of cuts for estimating forage productivity in panicum maximumNúmero de cortes para estimativa da produtividade de forragem em panicumm maximum
(2016-01-01)
The evaluation of the coefficient of repeatability (r) allows verify if the superiority or initial inferiority of an individual remains over the measurements, being important for genetic breading programs with forages. ...
Análise económica da colheita mecanizada do café utilizando repetidas operacòes da colhedora
(2015-01-01)
Despite the mechanized harvest of coffee is more economical than manual harvesting in general, it is not able to fully replace the workforce, especially in high crop load. One of the ways to reduce the cost ofproduction ...
Characterizacion of bananas after application of different fungicide in post-harvest
(Fundacion General Univ Politecnica Madrid, 2014-01-01)
Little information exists about the postharvest behavior of bananas after application of fungicides in the Registro-SP region. This study aimed to evaluate the soluble solids (degrees Brix), pH, and total acidity of the ...
