It is highlighted that water balance modeling testifies that the trend to an increase in water demands for crop production is obvious reality for all the drip subsurface, micro-sprinkler) should be done to save water resources and provide the best out pay of them [Wang et al, 2021].…”

Global climate change has led to significant shifts in local climatic conditions of Ukraine with the trend to aridity aggravation. Sustainable crop production is at risk due to the aridity level increase. The study is aimed to evaluate aridity index in Ukraine (on the whole country and individual regions' scales) and the needs in irrigation using hydro-meteorological data of the key regional stations for the periods of 1961-1990 and 2010-2020. The results of hydro-meteorological evaluation were supported by the data on the soil moisture regimes provided by Soil Explorer service. The general trend to aridity aggravation in Ukraine was proved. It was found out that modern climate in most territory of Ukraine is semi-arid, dry subhumid and humid zones are observed in the western regions only. Humid soil moisture regimes (ustic and udic) are observed in the West and the North of the country. As a result of combined analysis of both aridity index and soil moisture regimes the conclusion was drawn that 46.05% of Ukrainian croplands cannot provide sustainable crop production without irrigation, 42.65% need irrigation for the cultivation of crops with high water use, and just 11.30% of the arable land require little or no irrigation.

“…In addition, the seed maize CWP increase by drip irrigation at larger farmland scales (15% on average) was less than that at small zone scales (>20%) found by Wang et al [82]. This could help explain why the positive effects of drip irrigation on CWP at the basin scale are not as obvious as those of previous site-scale studies.…”

Water scarcity threatens food security in arid areas, highlighting the importance of water-saving agriculture for food production. Agricultural management practices are developed to improve water-use efficiency, and their water-saving effects are generally evaluated at the field scale rather than the regional scale. To figure out the regional water-saving potential of irrigation methods and mulching practices, the FAO AquaCrop model was first calibrated and validated at the three experimental stations. With aggregating spatial information, a distributed model was constructed and validated in a typical arid river basin of northwest China. Twelve combinations of soil mulching (plastic and straw) and irrigation methods (basin, furrow, drip, and subsurface drip) were simulated using the model to evaluate the effect of agricultural management practices on crop evapotranspiration (ET), crop water productivity, and regional water consumption. The results showed that soil mulching, advanced irrigation methods, and their combinations reduced noneffective soil evaporation (E) and the E/ET ratios and improved crop water productivity. Plastic mulching combined with subsurface drip irrigation is the most promising practice, increasing the crop water productivity of seed maize and spring wheat by 18.2% and 11.1% on average and reducing regional crop water consumption by 7.7% (75.0 million m3) and 7.4% (72.7 million m3), respectively. The reduction in irrigation water extraction ranged from 20.6% under furrow irrigation with straw mulching to 68.7% under subsurface drip irrigation with plastic mulching. This study quantitatively assessed the water-saving potential of soil mulching, irrigation methods, and their combinations to reduce agricultural water use, offering practical implications for the management and development of water-saving agriculture in arid areas.

“…Maize is a plant particularly predestined for cultivation under irrigation conditions, as evidenced by the results of domestic [20,[35][36][37][38][39][40][41] and foreign research [42][43][44][45][46]. In climatic zones where water is the primary yield-forming factor in crop production, modern studies are focused on the impact of the so-called deficit irrigation on the yield and quality of maize grain.…”

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.
