Method In a pot experiment, Solanum melongena seeds were sowed in soil mixed with spinach powder and compost while the control pots were without any amendment to the soil. The spinach -amended soil, compost-amended soil, and control soil sample were compared in terms physiochemical characteristics like pH , EC ,TDS, organic matter , nutrients i.e. nitrogen , phosphorus, potassium ,calcium ,magnesium and heavy metals. While, plant morphological traits plant height, root length, numbers of flowers and fruits were recorded. Results The pH of spinach-amended soil was slightly alkaline before plantation as compared to control soil. The nitrogen, phosphorus, and potassium content in spinach dry powder was 15%, 36% and 49%, respectively. The organic carbon content was 56% with moderate amount of micronutrients like calcium, magnesium and iron. Spinach powder-amended soil significantly improved the plant morphological characteristics like stem height, root length and able to produce more flowers and mature fruits as compared to compost-amended soil and control soil. Conclusion The use of spinach in powder and liquid concoction was a suitable alternative to chemical fertilizers. It was able to deliver all major macro- and micronutrients to soil thus improving the fertility and has significant impact on plant growth and yield.   Highlights The organic fertilizer-derived spinach powder is beneficial since it can greatly minimize the amount of chemical fertilizers usage while also produced high-yielding plants that were free of dangerous pollutants.}, journal={International Journal of Recycling of Organic Waste in Agriculture}, publisher={OICC Press}, author={Javed, Hifza and Iram, Shazia and Bilal, Barira and Tassawar, Tehreem}, year={2023}, month={Nov.}, keywords={Food Security, Plants fertilizers, Sustainable approach, Organic amendments, Soil fertility} }
