After application of treatments in the soil, the results of the study showed that vegetable waste had the highest yield per head (355.5 g) followed by synthetic fertilizer and no fertilizer treatment (control) with 283.2 g, and 253.1 g, respectively. The vegetable food waste liquid fertilizer was analysed and the NPK values were found to be 0.83 %, 16.5 mg/kg, 20.62 cmol/kg, respectively. The vegetable food waste was processed in a closed container along with addition of stillage and sugar in anaerobic conditions for 3 weeks. There were three replications per treatment. The experiment was a randomized block design with N:P:K at ratio of 2:3:2(37) inorganic fertilizer, organic fertilizer (vegetable food waste) and no fertilizer as the three treatments using no fertilizer as a control. The main aim of this study was to investigate the effect of organic food waste on the condition of soil and the yield of vegetables. ) Grown in the malkerns area, a region in the kingdom of eswatini.
