“…Still, for the same concentration, the downhill system showed better behavior when compared to the uphill system, as it presents less variability for the data set. Lopes et al (2021a) obtained satisfactory results for flow uniformity when applying a concentration of 3 g L -1 of MPK.…”

“…According to (Szekut et al, 2018) the operation of lateral drip lines is affected by the topography of the irrigated area and represents, depending on the type of water applied, changes in the discharge characteristics of emitters. For example (Lopes et al, 2021a) found excellence in flow uniformity at all slope levels when evaluating fertigation with MPK.…”

The use of statistical process control tools in irrigation is becoming widespread as it allows for quick and effective investigation and detection of possible problems with drippers, especially when fertilizer is used in irrigation water and different slopes. Therefore, the research used statistical quality control charts to monitor urea concentration at different inclinations of the lateral line. The experiment was conducted in a protected environment at the Irrigation and Fertigation Laboratory - LIF) in the city of Cascavel, Paraná State, Brazil. It followed a randomized block design, in a 4x3 factorial arrangement, in which fertilizer concentrations were evaluated at three slope angles. Experimental plots were divided into two factors. The first is the type of water (clean water from an artesian well and water with a nitrogen fertilizer at 44% N) subdivided into four subplots, representing concentrations of urea (0, 2, 4, and 6 g L-1). The second factor was slope angle and represented the sub-plots: uphill (2%), level (0%), and downhill (2%). The results show that Shewhart's statistical control charts were sensitive in observing the change in uniformity due to the increase in fertilizer concentration. Water with fertilizer (4 gL-1) affected uniformity at all studied slope levels. The results also show that high concentrations of fertilizers change the pH of the water. The lowest urea concentrations showed the best distribution uniformity results. Keywords: control charts, drip irrigation, Shewhart, uniformity.

Topographic slope negatively affects irrigation uniformity when associated with fertilizer application via irrigation water. The concentration of the injection solution at the emitter outlet can adversely affect the uniformity of the drip system. Therefore, the objective was to evaluate the ideal concentration that maintains high levels of uniformity for the nitrogen solution, applied via fertigation, in different concentrations of the injection solution, with different levels of slope. The experiment was conducted out in a protected environment at the Laboratory of Irrigation and Fertigation (LIF), Cascavel-, PR. The experimental design was conducted out in randomized blocks in a 4x3 factorial scheme, in which the concentration of fertilizer was evaluated at three levels of slope: with plots divided into two factors, the main factor being the type of water, represented by four plots: clean water (from artesian well) and water with nitrogen fertilizer, urea (44% N) in three concentrations (2 g L-1; 4 g L-1; 6 g L-1); and as a second factor, the slope levels, represented by the subplot: level (0%), uphill of 2% and downhill of 2%. The addition of 4 g L-1 urea concentration affected the uniformity at all slope levels, presenting values for UD< 90%, observed in the Shewhart control chart. The increase in urea concentration by 6 g L-¹ affected the distribution uniformity of the system in level, with values for UD< 70%. The system was able to apply concentrations up to 2 g L-1 in level, presenting Cpl = 2.86.
