ABSTRACT: The radish cultivation (Raphanus sativus L.) has been conducted mainly by family farming, for which demands for more economically and sustainable strategies, and in this case, the use of organic fertilizers have been a fundamental tool in relation to increase the productivity and improve the quality production. The objective of the research was to analyze the agronomic characteristics related to height, stem diameter and number of leaves of R. sativus plants grown under different sources of organic fertilizers. The experiment was conducted in the University of Araraquara (UNIARA), composed by four treatments and six replicates, in a randomized block design, characterized by a control (without fertilization) (T1), and also by three sources of organic fertilizers: cattle manure (20 %) (T2), vegetable compost (20 %) (T3), and earthworm humus (20 %) (T4). The parameters analyzed were the average plant height (cm), average stem diameter (mm), and average number of leaves (n), with the evaluation performed at 35 and 50 days after sowing. Organic fertilization based on earthworm humus provided a significant increase compared with the control in terms of plant height at 35 and 50 days after sowing, with positive and significant results related with the stem diameter at 50 days after sowing. The organic fertilized characterized by cattle manure provided a higher height of R. sativus plants at 50 days after sowing, when compared with the control, while the vegetable compost did not assist the development of radish culture related to agronomic characteristics analyzed. Organic fertilizer related to earthworm humus, at a concentration of 20%, helps the growth and development of radish plants, especially concerning the agronomic characteristics of height, and stem diameter, while cattle manure provides greater growth of R. sativus plants.
