“…According to hydrotropism, each root serves as a water sensor which can perceive water potential gradients and modify their growth direction towards higher moisture [27]. It can be assumed that plants with fewer roots distributed in the dry soil can perceive wet zones more precisely, which is preferable in subsurface irrigation to make more e cient use of the irrigation water in the wet zone [8,54,55]. Our study provides a method to quantify root distribution that is against hydrotropic responses.…”

BackgroundSubsurface irrigation has been confirmed to have high water use efficiency due to it irrigating only the crop root zone. Hydrotropism allows roots to grow towards higher water content areas for drought avoidance, which has research interests in recent years. However, most hydrotropism studies focused on a single root and were conducted in air or agar systems. The performance of hydrotropism in subsurface irrigation is not clear. ResultsWe developed a method to observe and analyze hydrotropism in soil under water-saving cultivation. A wet zone was produced around the whole root system based on using subsurface irrigation method and micro soil water dynamics were observed using high-resolution soil moisture sensors. This method enabled the observation and analysis of plant water absorption activities and the hydrotropic response of the root system. In the analysis, we first applied a high-pass filter and fast Fourier transform to the soil water dynamics data. The results indicated that the plant’s biological rhythm of photosynthetic activities can be identified from the soil moisture data. We then observed root growth in response to the dynamics of soil water content in the wet zone. We quantified root distribution inside and outside the wet zone and observed the shape of the root system from the cross-section of the wet zone. The results showed that the root hydrotropic response is not uniform for all roots of an individual plant. ConclusionsThis study verified the feasibility of using high-resolution soil moisture sensors to study root hydrotropic responses in soil during water-saving cultivation. To further evaluate a plant’s hydrotropic ability, it is necessary to use statistical analysis and/or a non-deterministic approach. Future studies may also explore developing an automated experimental system and robotic manipulations for getting steady repeatable observation of hydrotropism in water-saving cultivation.

“…The deficiency of this method needs to be addressed. Subsurface capillary irrigation has the potential of achieving precision irrigation and improves water use efficiency as reported by Li et al, (2018), Zainal Abidin et al, (2014 and Idham et al, (2018). Capillary irrigation is a subsurface type of irrigation, where water is transported from the water source directly to the root zone of the plant using different capillary media such as fibrous, wicks, mat and flow system (Semananda et al, 2018).…”

The demand for freshwater and food is on the increase due to the rapid growth in the world’s population, while the effect of global warming and climate change poses a severe threat on water use and food security. Conventional irrigation system suffers due to an inefficient management of water and energy, while insufficient supply of water to plant increases their stress which often affects its growth and development. Hence, there is a need to increase research focus on water use efficiency in irrigation agriculture. This paper is aimed at investigating the performance of smart drip and subsurface fibrous capillary irrigation experiment for the cultivation of cantaloupe plant to increase the yield and quality of fruit while decreasing the water and energy usage. To achieve enhancement of subsurface fibrous capillary and drip irrigation system, an Internet of Things (IoT) approach was used to improve monitoring of soil, weather, plant and control of water application. The performance comparisons of both methods was evaluated in terms of water-saving in greenhouse cultivation experiment. The results obtained, shows that the smart fibrous capillary irrigation has water use efficiency of 19 g/Litre with average fruit sweetness of13.5 Brix. While, drip irrigation has 4.85 g/Litre and average sweetness of 10 Brix on the harvested fruit after 90 days of cantaloupe plant cultivation experiment. These have shown that precision irrigation through enhanced smart fibrous capillary irrigation can be used to achieve high water-saving and a good quality yield. It is expected that the research output will help to improve water-saving agriculture towards achieving food security.Keywords: Water Saving; Capillary Irrigation; Drip Irrigation; Internet of Things; Water Use Efficiency

“…Part 5, the study of point sources, relates to the design of SDI systems and crop planting methods for optimized efficiency. The distribution of point sources not only has a significant impact on soil water depletion and moisture peak, but also limits the amount of tilling and crop spacing [37][38][39][40]. However, the timeline node distribution indicated that point source research was initially a hot topic but has gradually become less popular in recent research.…”

To investigate the research hotspots and development trends of subsurface drip irrigation (SDI) over the past 20 years, this study analyzed relevant literature from the Web of Science Core Collection spanning from 2002 to 2022. The data were visualized using CiteSpace, showcasing the publication volume trends, countries, keywords, cited references, authors, and affiliated institutions. Based on 1079 articles, the annual publication volume showed an overall upward trend. The United States had the most extensive research coverage and highest publication volume, whereas China had the fastest growing publication rate in recent years. However, relatively little cooperation occurred among research teams and institutions. Over time, research topics became increasingly diverse, with water conservation and yield increases being the primary research objectives. In addition to improving irrigation and fertilizer use efficiency, SDI has also been applied in research on the safe utilization of unconventional water resources (wastewater and salt water) and the optimization of soil conditions. Among these, aerated irrigation technology—aimed at improving root growth in the rhizosphere—may become a new branch of SDI research. Currently, the main research focus in the field of SDI is the diffusion and distribution of water in the crop root zone, for which Hydrus model simulation is a particularly important method.
