“…It is known that asparagus plants exhibit a notable resilience to soil water shortages owing to their deep and robust root systems [64][65][66][67][68]. However, much research conducted worldwide confirms the beneficial effect of irrigation on this species, especially during the fern development period, on its yield [69][70][71][72][73][74][75][76][77][78][79][80][81][82][83][84]. Currently, particular emphasis is placed on water-saving irrigation techniques, including drip irrigation, which, following principles, allows for rational management of this extremely valuable natural resource, water [85][86][87][88][89].…”

“…Currently, particular emphasis is placed on water-saving irrigation techniques, including drip irrigation, which, following principles, allows for rational management of this extremely valuable natural resource, water [85][86][87][88][89]. Efforts to reduce the amount of water used to irrigate asparagus are particularly important in water-deficient areas and on light and sandy soils [24,31,36,37,69,71,80,84]. It was found that it is possible to reduce the amount of water used to irrigate asparagus thanks to an appropriate system monitoring this process [72,76,79,80,82,83].…”

Water is a valuable yet scarce resource in agriculture. Optimizing crop production relies on irrigation, but within the framework of sustainable agriculture, efforts should prioritize reducing irrigation water usage. Unfortunately, climate change increases plant water requirements, consequently heightening the need for irrigation. The aim of the research was to estimate the water needs of asparagus during the fern growth period (21 June–31 August) using the Blaney–Criddle method. The study also aimed to determine trends in changing water needs and estimate precipitation deficits. Calculations were carried out for the years 1981–2020 across four provinces in central Poland. The research indicated that water needs varied between 233 mm and 242 mm, depending on the province. Over the forty-year period, all provinces displayed an increasing trend in water needs, with a rise of 3.1 mm to 6.2 mm per decade. Between 21 June and 31 August, rainfall deficits occurred with varying intensity in all provinces during normal, medium dry and very dry years. The values of water needs and rainfall deficit, calculated as a result of the research, are of key importance in the design, construction, and management of drip irrigation systems for asparagus plantations in central Poland.
