ABSTRACT
Nowadays, to produce healthy foods, application of compost and other organic fertilizers has received more attentionas a suitable alternative for utilization of chemical fertilizers. This study was conducted to evaluate the effect of chickenmanure tea and vermicompost application on some quantitative and qualitative traits in seedling and mature greenhousecucumber (Cucumis sativus cv. Extreme), in a research greenhouse in Iran’s Tehran Province. The experiment was factorialin a randomized completely block design with four replications. Treatments were control (without any fertilizer), controlwith chemical fertilizer (20-20-20), vermicompost in two levels (20 and 30%), and chicken manure tea (25, 50, and 75%).Results showed that increasing the amount of chicken manure tea (up to 50%) significantly increased shoot length, stemdiameter, true leaf length and width, shoot fresh and dry weights, and chlorophyll content, days until flowering, yield(40, 65, and 90 days after culturing), marketable fruit ratio to second degree fruit, and total fruit weight of cucumber. Byenhancement in content of chicken manure tea (75%) all traits showed the same result as treatment with chemical fertiliz
