Special Issue Information

Dear Colleagues,

Climate change has become a major challenge impacting world food production and crop water management. Crop production substantially relies on irrigation. At present, irrigated farmlands have contributed more than 50% of global available calories; meanwhile, crop irrigation consumes more than 60% of water withdrawn worldwide. Given the expansion of irrigated farmland, water shortage is escalating in the agricultural sector. Great efforts should be made to balance the water needs and supply while achieving high crop productivity. However, the climate system is changing, and the global average surface temperature has increased 0.65–1.06 °C. Climate change brings about temperature rises and erratic rainfall, increasing crop vulnerability in yield formation. Crop water needs are expected to markedly increase with global warming, further accelerating the world’s water crisis. In this context, global food security should be guaranteed by optimizing crop water management and improving crop adaptation to climate change. Understanding crop water needs under climate change is of irreplaceable importance for the sustainable development of agriculture. This Special Issue aims at providing an overview of the latest developments in the major fields of crop water needs, water physiology, drought mitigation, water-saving techniques, smart irrigation, and strategies for optimizing crop water management in the context of climate change. With its paramount importance to meet the goal of global food and water safety under climate change, we welcome original research articles and reviews to this Special Issue entitled “Water Needs of Crops and Irrigation Management under Climate Change”.

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. Agriculture 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 2600 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.

Periods of heat and water deficit often occur together and are especially dangerous for plants grown in pots, where the substrate volume for roots is limited. The purpose of the present research was to understand the response of shrubs planted in containers to the addition of a starch-based superabsorbent to their growing medium. The growth parameters, physiological conditions, and oxidative stress of Cornus alba ’Aurea’, Hydrangea paniculata ‘Limelight’, and Physocarpus opulifolius ‘Red Baron’ were assessed by adding a hydrogel (1, 2, or 3 g·dm−3) to their growing medium. The use of the superabsorbent improved the stomatal conductance and photosynthetic rate, resulting in better growth parameters. The application of 1 g·dm−3 hydrogel increased the chlorophyll content in hydrangea and ninebark leaves (8%) and increased the content of total soluble sugars in these plants (12% and 15%, respectively). The highest increase in reducing sugars was caused by a dosage of 3 g·dm−3. The lowest dose of hydrogel resulted in a decrease in hydrogen peroxide content in the leaves of all the taxa. The relationship between the contents of biologically active components and oxidative stress proved ambiguous for all the taxa. Oxidative stress was reduced, as evidenced by lower hydrogen peroxide and an increase in pigment content. In summary, a hydrogel dosage of 2 g·dm−3 in the medium could be optimal in pot nursery production using 3 dm3 pots. Full article

Dual use of water for fish and crop production could be a promising approach to improve irrigation under arid conditions. A watercress pot study was carried out to assess the effects of irrigation by catfish and tilapia aquaculture water on the sandy soil properties as well as the growth parameters of watercress with various combinations of artificial NPK fertilizers at El-Minia Governorate of Egypt (28°18′16″ N latitude and 30°34′38″ E longitude). Catfish aquaculture water had the greatest phytoplankton abundance at 83,762 units (×104/L), while the minimum number of phytoplankton existed in tilapia aquaculture water, recorded at 14,873 units (×104/L). There were significant average changes that varied from 120 to 237 (×104 cfu/mL−1) in total bacterial counts in tilapia and catfish waters. Watercress growth quality parameters closely paralleled at all NPK application rates, indicating that the highest quality plants were produced in pots receiving 25% of the recommended levels and irrigated with catfish aquaculture water. Nitrate concentrations of watercress plants were determined under pollution levels established by the European Commission for leafy and tuber vegetables. In conclusion, the use of microbial and phytoplankton-rich aquaculture water to irrigate vegetables and as fertilizer can maintain a balanced soil ecosystem. Full article
