Abstract:

ABSTRACT The study aimed to evaluate the water distribution from a medium-size sprinkler working in solid set sprinkler systems. Water distribution radial curves from the sprinkler operating under four nozzle diameter combinations (4.0 x 4.6; 5.0 x 4.6; 6.2 x 4.6 and; 7.1 x 4.6 mm) and four working pressures (196; 245; 294 and 343 kPa) were evaluated on the sprinkler test bench of the State University of Maringá, in Cidade Gaúcha, Paraná, Brazil. The sixteen water distribution curves were normalized and subjected to clustering analysis (K-Means algorithm), identifying the occurrence of normali

Abstract:

Circular self-propelled sprinkler systems are highly efficient equipment for watering crops by sprinkling. Considering the diameter of irrigation, uniformity and productivity of the installation largely depend on the parameters and relative location of sprinklers on the main pipeline of the sprinkler machine, the assessment of the parameters of artificial rain for compliance with the set values for irrigation conditions requires appropriate theoretical and practical studies.

Abstract:

A computer model was developed to simulate the varying depths of water applied to the ground due to the intermittent movements of a typical center pivot. The stop–go model inputs include the sprinkler application depth, the sprinkler pattern, that pattern’s wetted radius, the center pivot’s % timer setting, the move cycle time, and the end tower maximum travel speed. The model outputs were the depth of application in the pivot’s movement direction, the distribution uniformity (DU), and the coefficient of uniformity (CU).

Abstract:

The complexity of assessing the irrigation performance of a solid-set sprinkler irrigation system implies analyzing factors of the sprinkler features, the spacing among sprinklers, the evaluation heights, the meteorological variables and the crop. In this research, a number of solid-set experiments with impact sprinklers were evaluated with different operating conditions and a number of models of irrigation uniformity (CUC) and losses due to drift and wind (WDEL) were assessed at different catch-can heights. Statistical analysis and predictive models were performed for each variable analyzed.

Abstract:

The study and analyses of erosion have shown that the main factors determining erosion processes under equal soil and climatic conditions are the intensity and structure of artificial rain and the ground slope. The main factor, artificial rain intensity, depends mainly on the soil infiltration rate. In sprinkle irrigation, the soil infiltration is preceded by interaction between the soil and the rainfall drops. Failure to observe this interaction has often caused irrigation erosion problems due to the impact drops on the soil. It has been proved that the bigger are rainfall drops and their int

The advantage of a sprinkler irrigation method is that it saves up to 50% of water consumption during the application of water, as compared to any other surface irrigation system.

Abstract:

In the past few decades, several coefficients of uniformity were developed to express the uniformity of water distribution for different sprinkler irrigation systems. Christiansen's uniformity coefficient seems to be the most popular uniformity coefficient used by researchers on the global scale. However, more coefficients have also been proposed by other researchers. Therefore, this study focused on evaluating different uniformity coefficients proposed and on investigating the effects of field conditions on the results obtained by means of those coefficients. In doing so, sprinkler uniformity

Abstract:

Capillary mats and overhead sprinkler irrigation were used in a simulated retail environment to maintain annual and perennial plants in containers for various time periods during summer and winter. Combining the results from both seasons, four species with dense canopies had larger canopy sizes when maintained on the capillary mats, three species requiring more drainage had larger canopies with overhead irrigation, and five species were unaffected by irrigation systems. Substrate electrical conductivity was higher for some species in winter for plants on capillary mats, conserving fertilizer c

Abstract. Analysis of the consumption rate when spraying sunflower with a self-propelled sprayer Horsch Leeb 5.300 VN has been made. By using data from the Horsch Telematics system, data have been downloaded from which the actual operating speed of the self-propelled sprayer during spraying has been determined. The consumption rate per hectare of 200 l/ha has been studied and the factors that cause the fluctuation in the set consumption rate for spraying have been determined. The set spray pressure value has been found to vary from 1.53 to 4.57 bar. Analysis of the sprinkling height of the wor

The task of substantiating the use of a booster pump with an electric drive and a long-range sprinkler apparatus at the extreme section of the sprinkler machine in comparison with the whole section is set in the work. Energy costs, an indicator of cost and operating costs are considered as indicators of comparison. Based on theoretical studies, the application areas of the booster pump were found for operating costs, taking into account the indicators of energy consumption, reliability and cost, calculated for

Abstract:

SUMMARYThe line-source sprinkler irrigation system provides a continuously variable water application rate, which depends on distance from the line-source. The system is simple to set up and minimizes the amount of land required for experimental work. As the irrigation treatments are allocated systematically, the assumptions of analysis of variance are not satisfied. It is proposed that the effects of irrigation treatments be assessed using analysis of covariance, with distance from the sprinkler line as covariate, thus adjusting for a linear fertility trend. This method of analysis provides a
