Characterization of artificial rainfall produced by a portable rainfall simulat...
Costa, Antônio Reynaldo de Sousa; Alvarenga, Lívia Alves; Thebaldi, Michael Silveira; Lima, Luiz Antonio; Colombo, Alberto; Green, DanielRainfall properties and drop spectra characterization is essential when designing and using rainfall simulators to properly replicate natural rainfall characteristics. This study considered a small-scale rainfall simulator operating under varying nozzle, pressure and rotating disc scenarios. A dynamic rainfall gauge system developed at the Federal University of Lavras was used to quantify the impact velocity of...
Water use efficiency of different production techniques for zucchini
Silva, Anita Cristina Costa da; Almeida, Willian Fernandes de; Lima, Luiz Antonio; Oliveira, Mayra Carolina de; Guimarães, Alexandre LasmarThe effects of pulse drip, drip line position and soil mulch on water use efficiency in yields of zucchini cv. Clarinda were evaluated. The experiment was conducted in the experimental area of the Engineering Department of the Federal University of Lavras, Lavras, Minas Gerais State, Brazil, for two years. For the first year of the experiment, the experimental design was a randomized block design with a 2 x 2 ...
Option of intercropping for irrigated coffee with corn and beans in the semiari...
Silva, Vânia; Pasqualotto, Allan Teixeira; Andrade, Fabrício Teixeira; Lima, Luiz Antonio; Carvalho, Gladyston Rodrigues; Rezende, Ramiro MachadoThe objective was to appoint an intercropping option for the cultivation of sprinkler irrigated coffee crops with corn and beans. During the first three semesters after its planting, the cropping coffee was carried out with different intercropping systems: two corn crops planted in 3 rows and one crop of 4 rows of dry beans; one crop of corn in 3 rows followed by one crop of dry beans in 6 rows and one crop of ...
Uniformidade de aplicação de água na irrigação de mudas de espécies florestais ...
Thebaldi, Michael Silveira; Lima, Luiz Antonio; Colares, Matheus de Figueiredo Braga; da Silva, Antônio Carlos; Lima, Pedro Luiz TerraSistemas de irrigação mal dimensionados aliados a manejos inadequados podem afetar o uso satisfatório da irrigação em viveiros, ocasionando desperdício de água e energia e, consequentemente, o desenvolvimento inferior das espécies. Sendo assim, os objetivos do trabalho foram avaliar a uniformidade de irrigação de um sistema de microaspersão, já instalado em um viveiro de mudas de espécies florestais, bem como a...

Economic and tecnical feasibility of coffee intercropped with papaya in Norther...
Silva, Vânia; Colares, Matheus Figueiredo Braga; Andrade, Fabrício Teixeira; Lima, Luiz AntonioThe objective of this study was to determine the technical and economic feasibility of intercropping coffee with papaya in different tillage systems. The systems were evaluated in monoculture coffee, coffee intercropped with papaya in the rows and intercropped with coffee planting papaya between the lines. The experiment was installed in a randomized block design with eight replications. The coffee grown in lin...
PRODUCTIVE CHARACTERISTICS OF ARABIC COFFEE IRRIGATED BY CENTRAL PIVOT IN THE R...
Silva, Antonio Carlos; Lima, Luiz Antonio; Evangelista, Adão Wagner; Martins, Carla PáduaIrrigation management in coffee (Coffea sp.) has been studied by several researchers in order to set the crop coefficientvalue (Kc) to be used to estimate evapotranspiration of coffee plantations. The adoption of a single value for different times of the yearcan result in water deficit or wastage of water and inputs. This work aimed to evaluate the productive characteristics of the coffeecultivar “Rubi” (Coffea...
