  In the past few years, the Web of Things (WOT) became a beneficial
game-changing technology within the Agriculture domain as it introduces
innovative and promising solutions to the Internet of Things (IoT) agricultural
applications problems by providing its services. WOT provides the support for
integration, interoperability for heterogeneous devices, infrastructures,
platforms, and the emergence of various other technologies. The main aim of
this study is about understanding and providing a growing and existing research
content, issues, and directions for the future regarding WOT-based agriculture.
Therefore, a systematic literature review (SLR) of research articles is
presented by categorizing the selected studies published between 2010 and 2020
into the following categories: research type, approaches, and their application
domains. Apart from reviewing the state-of-the-art articles on WOT solutions
for the agriculture field, a taxonomy of WOT-base agriculture application
domains has also been presented in this study. A model has also presented to
show the picture of WOT based Smart Agriculture. Lastly, the findings of this
SLR and the research gaps in terms of open issues have been presented to
provide suggestions on possible future directions for the researchers for
future research.
