Use of macroalgae Porphyra umbilicalis in the emergence, growth and production in the cultivation of radish "Raphanus sativus L"

Radish (Rhapanus sativus) is a vegetable that is grown worldwide, so many producers use chemicals to increase production. An alternative to avoid the use of chemicals in radish cultivation is the use of algae-based green manures. For their nutritional advantages that they can contribute to agriculture. The objective of this work was to evaluate the agronomic and productive behavior of radish “Raphanus sativus” under the effect of fertilization based on the macroalga Porphyra umbilicalis also known as “Nori”. A Completely Random Design (DCA) with four treatments and an experimental control with five repetitions is used. The treatments correspond to T0: experimental control (0% Nori seaweed); T1 100% Nori seaweed; T2 at 75% Nori seaweed; T3 at 50% Nori seaweed; T4 at 25% Nori seaweed. 10 plants per experimental unit were used, that is, 50 plants per treatment with a total of 250 plants for all treatments. The results indicated that the exposure of the Nori seaweed prior to planting did not represent any advantage in the percentage of emergence, however, in the variables of height (34.32 cm), width of leaves (9.18±1.45), length of leaf (2 ±0.69), weight (31.6±3.14 g), fresh biomass (23.90±2.59), dry biomass (1.57±0.41) and yield 31.2 kg for treatment T4 fertilized with 100% Nori seaweed presented the highest values. Concluding that the use of nori seaweed as a biofertilizer can give advantages in the production of vegetables such as radish.
