Resumo:
Radish (Raphanus sativus L.) is a short-cycle tuberous vegetable, which reserves a
significant amount of nutrients from the soil. It has great nutritional requirements, deficits
or excesses, which lead to losses in its physiology, which can hardly be reversed.
Research involving the proper management of fertilization in radishes, aiming to achieve
good productivity with low impact on the environment, are important for increasing
productivity and crop quality. Thus, based on what has been exposed, the objective of this
research was to evaluate the performance of the radish culture regarding its productivity
on organic poultry substrate. The experimental design was completely randomized with
five treatments containing soil and organic matter in the substrate, as follows: T1 – Soil
only; T2 – Soil + 10%; T3 – Soil +15%; T4 – Soil + 20% and T5 – Soil + 25% of poultry
manure, respectively, resulting in 20 experimental plots and 120 pots. The number of
leaves, fresh shoot mass (g), tuber weight (g), dry shoot phytomass (g) plus root dry
biomass (g) and the occurrence of pests were evaluated. The performance showed linear
growth as the percentages of poultry manure increased, however, this is not significant,
due to the fact that there will be a point where the addition of manure will no longer result
in increased productivity. Regarding the occurrence of pests, the species did not present
occurrences that justified the use of pesticides.
