Abstract
The objective of this work was to evaluate the vegetative development of radish seedlings in different organic substrates with seeds from two types of commercial packing. The completely randomized design was used in a 4 x 2 factorial scheme, consisting of four substrates (commercial, tanned bovine manure, mixed organic compound and vermicompost) and two seed packings (aluminized envelope and can), with eight replications, totalizing 64 seedlings. The biometric evaluations of the seedlings were carried out on the 14th day after sowing, and the following phytotechnical parameters were evaluated: leaf number, total fresh mass; fresh mass from aerial part and fresh mass from the root. According to the results, the commercial, vermicompost and mixed organic substrates provided the best results for the variables evaluated when the can was used.
