13. SPATIAL VARIABILITY OF THE WATER DEPTH APPLIED BY FIXED SPRINKLER IRRIGATION SYSTEMS
Abstract The uniformity of water application is an important factor in the evaluation of sprinkler irrigation systems. This uniformity depends on the type of sprinkler and its operating conditions, such as the arrangement and spacing between the sprinklers in the area; velocity and wind direction during the period of water application and the pressure variat

14. PEANUT CULTIVARS SUBMITTED TO IRRIGATION LEVELS AND NITROGEN ADUBATION IN TROPICAL CLIMATE
ABSTRACT: The objective of this study was to define the best irrigation level in a sprinkler system, submitted to nitrogen doses in covering in the municipality of Tangará da Serra - MT, for two cultivars of peanut (Arachis hypogaea L.). The experiment was carried out in the experimental field of the State University of Mato Grosso (UNEMAT), located geograp

15. IRRIGATION STRATEGIES WITH WATER DEFICIT IN ‘TOMMY ATKINS’ MANGO TREE
ABSTRACT With the limited availability of water in semi-arid regions, it is necessary that irrigation is accurate and there is high water use efficiency. This study aimed to evaluate the regulated deficit irrigation (RDI) and partial rootzone drying (PRD) in yield, water use efficiency and gas exchange of ‘Tommy Atkins’ mango tree in semi-arid conditions

16. Leaf gas exchange and yield of three upland rice cultivars
Studies of physiological parameters associated with crop performance and growth in different groups of upland rice (Oryza sativa L.) may support plant breeding programs. We evaluated the role of gas exchange rates and dry matter accumulation (DMA) as traits responsible for yields in a traditional (cv. ‘Caiapó’), intermediate (cv. ‘Primavera’) and mo

17. Variabilidade espacial da uniformidade da lÃmina de Ãgua aplicada por sistemas fixos de irrigaÃÃo por aspersÃo / Spatial variability of water level uniformity applied by fixed sprinkler irrigation systems
Water application uniformity is an important factor to be considered in the evaluation of sprinkler irrigation systems. The uniformity depends on the type of sprinkler and its operational conditions, the display and space among the sprinklers on the field, and also the wind speed and direction during the water applying period. This work contributes to develo

18. Depósito de calda sobre linhagem de milho aplicada por pulverização terrestre e aérea e por quimigação para o controle de Spodoptera frugiperda (Smith, 1797) (Lepidoptera: Noctuidae) / Spray deposits of aerial, ground and through sprinkler irrigation applications on corn crop for control of Spodoptera frugiperda (SMITH, 1797) (Lepidoptera: Noctuidae)
A aplicação de produtos fitossanitários pode ser feita utilizando pulverizadores terrestres, avião agrícola ou via água de irrigação, contudo a seleção da melhor técnica é difícil, dada a pequena quantidade de estudos comparativos entre elas. Assim, o objetivo deste trabalho foi estudar a deposição do inseticida clorpirifós na cultura do milh

19. PropagaÃÃo vegetativa de miniestacas de Cordia trichotoma em funÃÃo de auxinas e Ãpocas de coleta / Vegetative propagation of Cordia trichotoma cuttings according to auxin and harvest time
It was developed a study on vegetative propagation on the rooting of Cordia trichotoma semi-woody in Summer and Fall of 2011. Therefore this study aimed to evaluate the effects of different concentrations of IBA (indolbutiric acetic) and NAA (naphthalene acetic) acids on the rooting and establishment of Cordia trichotoma semi-woody cuttings gathered from the

20. Controle do processo da irrigaÃÃo no sistema de aspersÃo convencional em Palotina-PR / Process control in a conventional irrigation sprinkler system in Palotina - Pr
IrrigaÃÃo por aspersÃo, mÃtodo artificial de aplicaÃÃo de Ãgua, supre total ou parcialmente as necessidades hÃdricas das plantas. Pode ser utilizada em vÃrias culturas, alÃm de ser facilmente adaptada a diferentes tipos de solos e topografias. A irrigaÃÃo deve ser feita em quantidade e uniformidade satisfatÃrias, pois à um importante fator a se

21. Performance and radial distribution profiles of a variable flow rate sprinkler developed for precision irrigation
Variable rate sprinklers (VRS) have been developed to promote localized water application of irrigated areas. In Precision Irrigation, VRS permits better control of flow adjustment and, at the same time, provides satisfactory radial distribution profiles for various pressures and flow rates are really necessary. The objective of this work was to evaluate the
