The objective of this work was to evaluate the performance of a drip irrigation system with photovoltaic energy without the use of energy storage system. The experiment was conducted at the State University of the West Parana - UNIOESTE, Campus of Cascavel, in the laboratory CASA project, during six days, analyzing the coefficients of uniformity of Christiansen (CUC), coefficient of uniformity of distribution (CUD) for measurement of 16 drippers by sector (Keller method) and later the coefficient of variation (CV). In the energy part, the irradiance and the current generated by the panel were analyzed. The irrigation set was also classified according to the ASABE standard. The statistical quality control of the system was also performed in order to evaluate the quality of the set considered, with the means being compared by the Tukey test at 5%. The coefficients of each treatment reached an excellent level according to their classifications. The main results allowed to evaluate that the flow control by dripper showed a significant effect for the factors analyzed. The system obtained excellent processability according to the analyzes of distribution uniformities. It was also concluded that there was a significant relationship between the coefficients (CUC, CUD and CV) with the process capacity of the flow data.

Initial Flow

The use of water in agriculture should be monitored in order to be more efficient, with irrigation being the largest consumer of water in rural areas. Small farmers who are part of family farming have few resources to develop profitable activities and aiming their well-being, have created family irrigation kits which is a small drip irrigation system. The systems durability depends of some factors like clogging risk of drippers, which is often caused by the quality of the water used or the application of fertilizers to the irrigation water. This research aimed to analyze a family irrigation system with application of red potassium chloride, followed by a chemical agent to clear drippers (calcium hypochlorite) with water application before and after the fertilizer and chemical products (four treatments). At the after, the evaluations were analyzed with statistical quality control charts where the problem was detected in the final of application of the fertilizer, and the process capacity was analyzed showing that it was capable and also was analyzed the degree of system clogging in relation to the obstruction with the fertilizer and clearing with the chemical agent, which resulted in the recovery of the irrigation system (initial flow and distribution uniformity same the final) with recommendations for the use of fertilizers by drip irrigation like open the end lines after the fertigation and dissolve the fertilizer fully before application.

Experiment was carried out in the department of Agricultural and Bioresources Engineering, during the period of August to October, 2017. The hydraulic performance of a developed drip irrigation system was assessed. The experimental work was conducted on field with irrigated field area of 7 m x 3 m and lateral spacing was 0.35 m. Sixty (60) hospital drip sets (given sets) were used for the experiment as improved emitters. Volumetric method was used to determine application rate (PR) and emitters discharge. The emission uniformity, emitter flow variation, co-efficient of uniformity and co-efficient of variation were determined accordance with the equations described by the American Society of Agricultural Engineering (ASAE). Soil chemical properties were determined accordance with the American Public Health Association (APHA). The findings revealed that the soil in the area is classified as sand clay loam and normal soil. Results indicated that the mean and standard deviation of the emitters were 9.639 L/hr and 0.07 L/hr respectively. There were no emitters clogging. The emitter flow variation was 2.5 % and less than 10 % which was desirable range, while coefficient of variation was 0.07 and less than 0.11 which was marginal. The application rate was 17 mm hr-1 which was within the recommended range of 15 – 25 mm hr-1. The emission uniformity and coefficient of uniformity were 99.4% and 99.2% respectively, which shows that the system was well-designed. This finding indicated that hospital drip sets proved to the high quality. Therefore, it can be used as standard emitter.

In the Caborca area, water scarcity is the main problem for the farmers, because of the depletion of the aquifer. This is the main reason why they are focusing on orchards and vegetables. Melon is the vegetable annual crop more extensively grown in this area and is furrow-irrigated with 120 cm of water. But, because of the scarcity of water, it is necessary to use drip irrigation. The objective of this study was to validate in a commercial field (15 ha) the effects of drip irrigation system on the water use, yield, and quality of two honeydew melon varieties (green flesh and orange flesh) in the Caborca area. Our results indicate that, with 50 cm of water applied, yields were 2146 to 2802 boxes/ha for green flesh and orange flesh, respectively. The predominant sizes were 4s and 5s with 25% and 38% for green flesh, and 5s and 6s with 42% and 36% for orange flesh. These sizes are the best for the exportation market.

This work aimed to evaluate the performance of a drip irrigation system with photovoltaic energy directly connected to the water pumping system through the irrigation uniformity coefficients using the statistical quality control, with the control chart of Shewhart. The experiment was conducted at the State University of West Parana (UNIOESTE), campus of Cascavel, in the Project CASA (Center of Alternative Energy System Analysis), during six days of open sky. The irrigation system contained four lines with 18 drippers each, collecting the flow of each dripper for five minutes, along with the parameters of temperature and solar radiation. In the energy part, the current and the voltage generated by the panel were analyzed. The main results allowed to evaluate that the flows of the drippers showed changes directly proportional to the decrease or increase of the radiation. Even with the changes in radiation levels during the collection period, the system obtained excellent process capability according to the analyzes of the distribution uniformities. It was also concluded that there was a significant relationship between the coefficients (CUC, DUC and CV) with the process capacity of the flow data. The control plot was adequate to diagnose the treatments. Statistical control proved to be effective for the determination of process variability, thus recommending the use of a drip irrigation system with a solar photovoltaic system directly connected to the pump on open sky days with few clouds due to the lower variability in relation to the graph of control and greater uniformity of water distribution.

Shewhart Control

This study monitored a drip irrigation system with different hydraulic heads, using control charts. The study included 25 tests, and was conducted at the Experimental Nucleus of Agricultural Engineering of the State University of Western Paraná, located in the municipality of Cascavel, Paraná. The drip irrigation system was operated by gravity, and had four hydraulic heads (10, 11, 12 and 15 kPa). The uniformity of the system was determined based on uniformity distribution. Uniformity monitoring was performed using Shewhart and exponentially weighted moving-average (EWMA) control charts. An increase in the hydraulic head increased uniformity. The use of 12 and 15 kPa hydraulic heads yielded good performance, whereas 10 and 11 kPa yielded regular performance. The use of control charts proved to be efficient; the Shewhart control chart was more robust, whereas the EWMA control chart, which indicated trends and deviations not shown by Shewhart control charts, was more sensitive.

Statistical Quality

The topography directly influences the functioning of an irrigation system, being necessary the determination of the uniformity to verify its performance. Statistical quality control is a powerful tool for verifying the quality of a process. Thus, it was aimed to use the statistical control of quality in the evaluation of the uniformity of a drip irrigation system in different slopes. The Christiansen’s uniformity coefficient (UC) and Uniformity of Distribution (UD) were determined and analyzed by the control graphs of Shewhart, Zones and CUSUM and by the indices of process capacity (Cp, Cpl and Cpk), in different slopes (0%, 2% and -2%). The slope irrigation was more uniform (UC = 99.03% and UD = 98.45%), however, for all the graphs studied it was out of statistical control. Zone charts were more sensitive than the CUSUM and Shewhart charts.
