Special Issue Information

Dear Colleagues,

The high demand for water and food due to an increase in population necessitates innovation in agricultural practices by developing irrigation practices to increase crop yield and improve water use efficiency. Irrigation is an unavoidable practice in arid and semi-arid regions. Therefore, there is a need to estimate actual irrigation water applied and to evaluate irrigation practices and techniques managing by farmers. Accordingly, the Special Issue aims to study maximizing the utilization of irrigation water using computer modeling techniques, such as artificial intelligence and computer programs, in determining crop water requirements, as well as studying the ability of field crops, fruit trees, and medicinal and aromatic plants for water stress. Moreover, this issue will focus on studying the application of modern agricultural strategies, such as various additions of mineral and biofertilizers and soil conditioners, which play a role in maximizing crop yield and quality and increasing water productivity. The so-called deficit and partial root-zone drying irrigation techniques in conjunction with surface and subsurface drip irrigation of high crop water use efficiency can maintain high crop yields if used properly. A proper and effective use of deficit irrigation requires knowledge of specific crop growth stages during which they are water-stress tolerant.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Relation between crop production and water;
  • Agronomical practice to improve crop water use efficiency;
  • Irrigation techniques (including fertigation);
  • Evapotranspiration
  • Water reuse;
  • Remote sensing applied to irrigation management;
  • Machine learning.

Oil palm is the second most cultivated oilseed crop in the world after soybeans, with more than 23 million hectares cultivated worldwide; it has become crucial for the economy of many countries. In Colombia, it is one of the most developed agricultural sectors, and every year the sector promotes the development of technologies that lead to greater sustainability of agricultural and food systems and address the challenges and opportunities of agribusiness. In this research, the central focus was the adoption of irrigation technologies, which is limited despite significant efforts and investments in physical and human capital. On many occasions, the typology of farmers has been associated with low technology implementation. Thus, linking the typology of farmers according to certain commonalities or differences is an essential step in exploring the factors that explain the adoption. In addition, the ranking also helps in the understanding of existing adoption constraints, as well as finding opportunities for change. This study aimed to determine the socioeconomic and demographic typology of those who adopt irrigation technologies. The analysis was performed using categorical principal component analysis to reduce dimensionality and fuzzy cluster analysis to classify the groups. As a result, four groups of producers that differ in terms of their demographic and socioeconomic characteristics were obtained, where the groups “population with female leadership” and “diversified population” were the adopters of irrigation technologies. The most outstanding characteristics of these two groups were the profitability of the harvest and the age of the producers. Determining the typology of farmers is a fundamental step in expanding the technology adoption process through agricultural extension services, which represent a way of reaching producers directly. In addition, these results allow decision makers to participate in this dynamic reflectively and intentionally (such as governments, researchers, and technology transferors). Full article

As the most important resource for life, water has been a central issue in the international agenda for several decades. Yet, the world’s clean freshwater supply is steadily decreasing due to climate change and extensive agricultural water demand for irrigated lands. Therefore, in addition to rational water use, we should use non-traditional water resources like Reclaimed Wastewater (RW). The present experiment was carried out in China over three years (2017, 2018, and 2019) to study the effects of two types of water qualities (reclaimed wastewater (RW) and clean water (CW)), two types of irrigation methods (Full irrigation (FI) and alternate partial root-zone irrigation (APRI)), and two types of irrigation techniques (Furrow irrigation (FUI) and subsurface drip irrigation (SDI)) on the main tomato fruit quality parameters. The APRI treatments obtained 70% of the FI irrigation water volume. The irrigation treatments of this study were: (1) SDI with APRI; (2) SDI with FI; (3) FUI with APRI; and (4) FUI with FI. These treatments were under RW and CW. Thus, the experiment consisted of eight treatments. The tomato fruit quality parameters studied were vitamin C (VC), total acidity (TA), protein content (PC), and total soluble sugar content (TSS). The results reveal that many measurements under reclaimed water (RW) had the highest values compared with clean water (CW), except in protein content (PC). The vast majority of values measured for PC under CW were slightly greater than the values under RW. Moreover, the results reveal that tomato quality in many measurements under APRI treatments increased compared with FUI. The statistical analysis generally shows that the fruit quality parameters were not significantly (p > 0.05) affected by the interaction between the irrigation treatments. In conclusion, the treatment SDI-APRI under RW can be an efficient irrigation method to reduce the consumption of clean water. Additionally, SDI-APRI offers a safe option because the physical contact between the wastewater, crops, and the farmers is minimized compare with the FUI treatment. Full article
