Abstract
Liquid organic fertilizers are organic solutions that are a valuable choice for sustainable agriculture. In addition, these organic forms play a significant role, in integrated waste management strategies. In this study, a one-way analysis of variance, Pearson correlations and principal component analysis were performed on all traits, to compare the responses of sole application of compost, compost tea, vermicompost tea and their combinations on growth, yield of Allium cepa and on soil properties. The results showed that, in most cases with fertilizers treatments, the soil pH, CaCO3 and bulk density were decreased, while soil organic matter, total N, available P and K were increased. A mixture of 50% compost, 25% compost tea, and 25% vermicompost had more desirable effect on plant height, leaves number, plant fresh weight and plant dry weight. Therefore, application of 50% compost tea and 50% vermicompost tea, it is possible to achieve an acceptable total bulb yield ton/ha, total soluble solids %, and dry matter %. While, available P, K in soil and P % in plant were raised when plants treated with teas sole or combined with compost 50%. Using a mixture of 50% compost, 25% compost tea, and 25% vermicompost tea, was a higher nutrient concentration and had a significant impact on onion plants productivity, and on soil properties.
