Agriculture plays a vital role in the food security and economies of Asian countries. Annually, numerous metric tons of vegetable and fruit wastes are disposed of. This research aimed to convert the food wastes encompassing the vegetable and fruit wastes into solid and liquid organic fertilizer and to evaluate their influence on the growth (germination, phytochemicals, and biomolecules) of Solanum lycopersicum and Capsicum annum. Solanum lycopersicum, known as tomato, and Capsicum annum, known as bell pepper or chili pepper, are globally significant crops valued for their medicinal properties and economic importance. The pot experiment was performed with organic fertilizers (solid and liquid organic fertilizer) and compared with the influence of chemical fertilizer and control soil without fertilizers. Interestingly, the liquid organic fertilizer effectively enhanced the biometric profile and chlorophyll content of S. lycopersicum and C. annum Viz., 1.23 mg g and 0.89 mg g, respectively. The results of a 30-days pot experiment with various fertilizer treatments showed significant influence of liquid organic fertilizer on the fresh and dry weight biomass of both S. lycopersicum and C. annum. Subsequently, the solid organic fertilizer showed considerable influence on test crops, and the influence of these organic fertilizers was more significant than the chemical fertilizer on crop growth in 30-days experiment. These results suggest that the sustainable approach can effectively convert vegetables and fruit waste into valuable organic fertilizer enriched with plant growth supporting essential nutritional elements.
农业在亚洲国家的粮食安全和经济中发挥着至关重要的作用。每年都有大量公吨的蔬菜和水果废弃物被处理掉。本研究旨在将包含蔬菜和水果废弃物的食物垃圾转化为固体和液体有机肥料，并评估它们对番茄和辣椒生长（发芽、植物化学物质和生物分子）的影响。番茄和辣椒是全球重要的作物，因其药用特性和经济重要性而受到重视。采用有机肥料（固体和液体有机肥料）进行盆栽试验，并与化肥和无肥料的对照土壤的影响进行比较。有趣的是，液体有机肥料有效地提高了番茄和辣椒的生物特征参数和叶绿素含量，分别为1.23毫克/克和0.89毫克/克。对不同肥料处理进行的30天盆栽试验结果表明，液体有机肥料对番茄和辣椒的鲜重和干重生物量有显著影响。随后，固体有机肥料对试验作物也有相当大的影响，在30天的试验中，这些有机肥料对作物生长的影响比化肥更显著。这些结果表明，可持续方法可以有效地将蔬菜和水果废弃物转化为富含支持植物生长的必需营养元素的有价值有机肥料。
