Abstract:

Exploratory research was conducted at Gobabeb Training and Research Centre, with the aim of obtaining data that could be used as a baseline study for future student research in desert agriculture and to help Topnaar communal farmers along the Kuiseb make use of available resources. The general objective of this research was to investigate the potential benefits of water recycling in crop production. Selection of three crops to be used in the experiment was based on salt tolerance levels of each crop; the three selected were peppers, tomatoes and beetroots. Each crop was divided into two groups and received two irrigation treatments, normal Gobabeb tap water from the borehole and recycled water. Height was recorded throughout the duration of the experiment to compare the growth of each crop, and water analysis was also done regularly to determine the amount of total dissolved solid (TDS) in the water. The result of the experiment shows significant differences between the two treatments of each crop. Crops irrigated with recycled water did better than the ones irrigated with tap water. The results were presented to Gobabeb Centre and the local Topnaar communities with the emphasis that, in future this system could be used as a water conservation process.
