Produtividade de rabanete cultivada com diferentes fontes e percentuais de matéria orgânica.

Abstract

Raphanus sativus L. is a vegetable belonging to the Brassicaceae family, which has a short cycle of approximately 30 days. The plant has a good economic and nutritional importance, as they contain a high nutritional value. The objective of this study was to evaluate the productivity of Raphanus sativus, grown in pots using goat and bovine organic substrate with different percentages, as well as to observe the best source of fertilization for greater productive performance. The experiment was conducted at the Olho D'água Novo site, Picuí, Paraíba, from June 7 to July 12, 2022. The experimental design was completely randomized, containing five treatments, with T1 = Soil only; T2 = Soil + 10% cattle manure; T3 = Soil + 20% cattle manure; T4 = Soil + 10% goat manure and T5 = Soil + 20% goat manure with four replications, totaling 20 experimental plots. The productivity of Raphanus sativus L. had a better performance in treatments T3 = Soil + 20% bovine manure and T5 = Soil + 20% goat manure, due to the higher percentage of organic matter contained in the substrate. It is concluded that the recommended source of organic matter is that contained in the T5 treatment with goat manure in its composition. The percentage of the most suitable organic fertilizer for growing Raphanus sativus in pots is 20%. The occurrence of insect pests in the crop did not reach 10%, which would be the level of economic damage to the crop.
