Special Issue Information

Dear Colleagues,

The main topic of this Special Issue is “Trends in Agricultural Surface Drip and Sprinkler Irrigation”. Considering that water is becoming an increasingly scarce and valuable resource, pressurized irrigation systems must not only seek water savings but also maintain the greatest possible amount of good quality water in reservoirs. By increasing water use efficiency, we not only increase the amount of water available for other uses, but also improve the environmental quality of irrigated areas, decreasing fertilizer and phytosanitary product losses and the contamination of groundwater. This increase in efficiency goes hand in hand with an improvement in the design of irrigation systems and an improvement in water management, linked to greater automation and support for control elements. In this sense, the latest trends in sprinkler and drip irrigation have a lot to say. The field is committed to developing increasingly efficient systems that support the greater sustainability of irrigation. Saving water is vital in many areas of the world, and applying the right amount of water at the right time is key to improving water use efficiency. Thus, the interaction of high-precision irrigation systems with an adequate estimation of the irrigation needs of crops can give rise to research and works of great interest. In this Special Issue, we hope to publish papers on new water application methodologies, improved designs and control systems, and novel applications of different existing sprinkler and drip irrigation systems. We welcome the submission of articles that improve or diversify current design systems to improve adaptation to invasive species or new crops. In short, we expect that this Special Issue will cover interesting news for both scientists and technicians and for society in general, which will benefit from these advances.

Maize is a plant of a global cultivation range and great economic importance, which is mainly due to its high yield potential and versatile use as food, fodder, and energy source. To evaluate the effects of drip irrigation and nitrogen fertigation on maize growth in light soil in the climate conditions of Central Poland, a field experiment was carried out in 2015–2017, as a dependent split-plot design with four replications. Two factors were used: I. drip irrigation (W0—no irrigation, W1—optimal irrigation, ensuring 100% coverage of the water needs of maize during the period of increased water needs), II—method of top dressing application of two doses of nitrogen 2 × 40 kg·ha−1 (T—traditional application as broadcasted urea, F—fertigation with the use of a 6% aqueous solution of urea). The results presented in the paper concerning the absolute, relative and unitary average increases in corn grain yields under the influence of drip irrigation indicated the potential for increasing significantly the productivity of corn under the condition of optimizing the water factor. The average yield increase was 2.35 t·ha−1, varying depending on rainfall pattern: in the dry season it was 4.79, and in the wet season 1.03–1.22 t·ha−1. The application of top-dressing nitrogen fertigation resulted in a significant increase in the yield of maize grain in relation to the traditional method of nitrogen fertilization. Drip irrigation and fertigation are treatments that, ensuring the stability of maize yield over the years, contribute to an increase in plant yield by approximately 25% on average, and over 80% in the dry seasons.
