Hydroponic farming for saffron cultivation in South Africa

Abstract

In South Africa, saffron has exclusively been cultivated using traditional farming methods. Although farmers face an increasing range of challenges and uncertainties, hydroponic farming offers an opportunity to alleviate many of these challenges, while simultaneously increasing output and reducing input expenses. The primary objective of the planned business venture was to investigate the possibility for hydroponic saffron farming in South Africa. The study focused on the development of a hydroponic system to cultivate saffron, aiming to mitigate the daily difficulties and risks faced by conventional farmers. The study adopted a qualitative exploratory research approach. The study gathered substantial information through interviews with farmers in both the traditional saffron and non-saffron hydroponic industries. Interviewing farmers provided insights into the perspectives of persons involved in both the traditional saffron industry and the non-saffron hydroponic growing sector. Three hydroponic cultivators and one saffron farmer were interviewed face-face. Another Saffron farmer was interviewed telephonically. The study examined the necessary requirements for hydroponic saffron cultivation in South Africa, covering technical factors for saffron cultivation, operational prerequisites, financials, market analysis, and challenges. The research findings highlighted the significance of hydroponic systems within an overall context. The main driving force for the transition from traditional farming to hydroponics was climate change among the participants. An essential challenge in hydroponic saffron growing is its relatively lower profitability compared to other crops like herbs, lettuce, and tomatoes. Including the concept of opportunity cost into the breakeven analysis will lead to a reduced repayment period, hence justifying the concept of saffron cultivation with a hydroponic system. In conclusion, cultivating saffron with hydroponics is a sustainable solution when considering opportunity costs due to the value of the spice, and the increasing uncertainty of climate change affecting output.
