This study aimed to investigate the effect of compost on the flowering and fruiting of Raphanus sativus cv Pusa chetki, a specific radish cultivar. Pot culture experiments were conducted under natural environmental conditions to replicate real-world growth scenarios. Pots filled with air-dried garden soil were used, each containing 20 seeds of Raphanus sativus variety Pusa chetki. Municipal compost was applied at concentrations of 5%, 10%, 15%, and 20% on a weight basis, with a control group without compost. No flowering and fruiting were observed in the compost-treated plants, while the control group exhibited 13-15 flowers and 7-8 fruits per plant. Even at 5% compost concentration, flowering and fruiting initiation were not effective. The application of compost seemed to hinder the physiological processes responsible for flowering and fruiting, as all compost levels, including 5% and 10%, inhibited these reproductive stages. More intensive investigations are required to understand the underlying cause of flowering inhibition under compost application. Due to varying experimental conditions, direct comparisons with other studies may not always be applicable, emphasizing the need for further experimentation. In conclusion, this study highlights that compost application at different concentrations negatively impacted the flowering and fruiting of Raphanus sativus cv Pusa chetki. Understanding the effects of compost on plant development is essential for optimizing its use in radish cultivation. Additional research will contribute to the knowledge of compost interactions with plants and assist in sustainable agricultural practices.
