This research performed studies about the performance of three bean varieties, during the winter, in Rio de Janeiro state, like an answer, to the application of differents irrigation levels, using a line source sprinkler ...

This research evaluated the effects of different management practices on the yields of irrigated cotton and upland rice crops grown on a saline-sodic alluvial soil of the Açu valley in the Rio Grande do Norte State, ...

A computer program based on regionally weighted regression methods and a generalized Regional Vector (Hiez, 1977, 1978) has been developed to check the consistency of and filling the missing values of the monthly and ...

In this work it was determined by simulations, the probabilities of occurrence of dryspell with different lasting period for a region of the “Cerrado” of the State of Mato Grosso. The data of precipitation were obtained ...

This work describes the procedures and methodology to simulate subsurface drainage of agricultural lands in the margins of the future reservoir of the Hydropower Plant of Porto Primavera, under construction by the Companhia ...

The crop of “murcote” tangerine was irrigated with three differents kinds of sprays providing three wetting areas and four irrigated depth of application and one not irrigated control. Predawn and between 11 and 12 hours ...

This paper's objective is to study the optimization of irrigated land using better-positioned center pivot sistems. Due to spacial complexity of individual situations, linear programming techniques are recommended to ...

The aim of this work it was to estimate by simulations the probability of occurrence of consecutive days with mild wind speed for a site of State of Mato Grosso. Wind speed lower than 172 Km/day it was considered mild. ...

The purpose of this research was to evaluate the water distribution effective diameter for the micro-sprinkler NAAN 7110, operating under laboratory and field conditions. It was verified that, for the field conditions in ...

This work was developed with the goal of evaluating the hydraulic characteristics of Big Swivel rotative micro-sprinkler, manufactured by Dan Sprinklers, such as the variation due to the manufacturing process and the ...
