Special Issue Information

Dear Colleagues,

Water scarcity is a significant problem in many areas across the globe, and agriculture is the greatest division of water consumption. During the 20th century, water demand grew at twice the rate of population growth, and by 2025, ≈ two-thirds of the world population is expected to be found in countries experiencing water-stress circumstances. Furthermore, climate change increases this risk by causing numerous harsh drought events or longer/dryer seasons. Although a water deficit can harmfully affect agriculture and result in noteworthy economic losses, one of the most promising approaches might be reducing water supplies during certain stages of crop growth. Thus, water conservation practices in the production of irrigated crops are crucial when managing soil water status in soils.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Horticulturae is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2200 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Sugarcane is a highly productive crop with high water requirements. In addition, its growth and sugar content are limited by the water deficit, a major problem affecting agriculture due to climate change. However, monitoring strategies are being developed worldwide that seek to increase productivity in the same area and with less water consumption. The sugarcane plants are produced sugar table, ethanol, and, from the hydrolysis of biomass, produce second-generation bioethanol, in addition to generating energy in thermoelectric plants. This research described the strategies and mechanisms used by sugarcane to tolerate water deficit. For this, a series of physiological, biochemical, enzymatic, morphological, anatomical, and ultrastructural analyses were developed. We used four commercial varieties of sugarcane, two tolerant and two sensitives, which were tested in all phases of the study. It was concluded that the variety RB92579 is drought tolerant as well as RB867515 and RB72454 genotype is sensitive to drought stress. Therefore, we proposed that variety RB855536 be assigned as an intermediary due to tolerance and sensitivity to water deficit. Full article

In order to explore water distribution in sprinkler irrigation systems under dynamic water pressure, an irrigation test was conducted in a sprinkler irrigation system equipped with the Hunter MP2000 full circular rotator ray sprinkler under “trapezoidal” waveform pressure to explore the influencing factors such as basic water pressure, dynamic pressure period, and the sprinkler combination spacing. The result shows that the basic pressure, sprinkler combination spacing, and their interaction significantly affected the coefficient of variation, average intensity, and coefficient of uniformity. The normalized comprehensive evaluation indexes were selected as the measurement standards. The optimal factor combination was found to be the basic pressure of 250 kPa, the dynamic pressure period of 200 s, and the sprinkler combination spacing of 6 m, and the corresponding evaluation index values were 0.08, 10.54 mm/h, and 93.20%, respectively. The uniformity coefficient was increased by 6.54% compared with the constant pressure of the same flow rate. Compared with the constant pressure of the same flow rate, the sprinkler area and the average intensity increased by 39.67% and decreased by 8.62% when the basic pressure was 250 kPa and the dynamic pressure period was 200 s. The average uniformity coefficient increased by 11.76% at the combined spacing of 6.0, 6.5, 7.0, 7.5, and 8.0 m. The results provide a theoretical basis for sprinkler irrigation decisions under dynamic pressure. Full article
