“…The subsurface drip irrigation system was shown to be more efficient; water was supplied directly to the radicular zone of the cauliflower plants, allowing for better use and a reduction of the rate of evaporation compared to the surface drip system. Geisenhoff et al (2015) saw similar results to those found in this experiment. Whilst studying irrigation systems in cauliflower crops, they obtained comparable differences between subsurface and surface systems; the subsurface system produced advantages for production.…”

The objective of this research is to evaluate the impact of soil management and localized irrigation techniques on water use efficiency in the cultivation of cauliflower. The treatments consisted of 4 different types of soil management: Direct seeding using crotalaria and brachiaria cover crops, a treatment used both in conjunction, and another that employed a conventional system. Two different irrigation techniques were used: Surface and subsurface. The experimental design was completely random in a factorial arrangement (4x2) with four repetitions. Each experimental unit was composed of 20 cauliflower plants, with a density of 1.8 m between rows and 0.5 m between plants. The experiment was carried out in two stages; the first stage consisted of the establishment of the cover crops and the second stage of the planting of cauliflower cv. Avenger in the different treatments. The cover species were cut at ground level 108 days after they had been sown. The cauliflower seedlings were grown in a protected environment and transplanted after 21 days. Irrigation was managed through the use of tensiometry. Water use efficiency was the variable that was analyzed; the Tukey Test at 5% level of probability was applied to the data that was obtained. A combined use of crotalaria/brachiaria cover crops with subsurface drip irrigation is recommended; this was the combination that most efficiently saved water.

“…The performance of an irrigation system is directly proportional to the improvement of crop production variables (Geisenhoff et al, 2015) and minimization of water and energy expenditures (Gris et al, 2015). Distribution uniformity is the main way to determine whether an irrigation system is acceptable or not (Brennan, 2008).…”

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.

“…A irrigação é uma técnica que consiste em fornecer água às culturas agrícolas, com objetivo de minimizar problemas como a falta e a má distribuição das chuvas. Porém, é uma tecnologia que está associada à utilização intensiva de insumos e requer elevados investimentos, sendo necessário um criterioso dimensionamento dos componentes (Geisenhoff et al, 2015;Pereira et al, 2016).…”
