- Abstract
The Food and Agriculture Organization (FAO) reports that fruits and vegetables have the highest wastage rates, possibly reaching 60% and they are valuable sources of phytochemicals. Among these phytochemicals are allelochemicals, a subset derived from plants' secondary metabolism. Allelochemicals offer advantages over herbicides, including lower toxicity, shorter persistence, and increased water solubility. A substantial reduction in crop yield has occurred due to weed infestations. To address this issue, it is imperative to employ modern control methods, including biological approaches. Recent research has proposed the utilization of allelochemicals to manage weeds, with the peels of papaya and pumpkin being identified as abundant sources of phytochemicals. Consequently, we conducted an evaluation of the allelopathic effects of papaya and pumpkin peels on the growth of Wheat and Ragi seeds using a sandwich method. Three different concentrations (0.05, 0.10, and 0.15 gm) of powdered peels were administered as treatments. The test species demonstrated both allelopathic potential and stimulatory effects. The results obtained suggest that papaya and pumpkin peels can serve as effective organic herbicide, albeit at specific concentrations. This application has the potential to reduce the reliance on conventional herbicides, which persist in the soil for extended periods compared to natural compounds.
