Adubações mineral, orgânica e organomineral na cultura do rabanete

Abstract

Radish (Raphanus Sativus L.) is a vegetable from the Brassicaceaes family, originated from the mediterranean region and it’s economical importance is dated to over 4.000 years. The organomineral fertilization is an advantage due to the fact that it conciliates advantages from the chemical and organic fertilizations. compensating it’s limitations. The experiment was conducted in a greenhouse located at the Federal University of Mato Grosso, Campus of Rondonopolis - MT, and it was performed in May and June 2018. The experiment had as it’s goal to determine the better source of fertilizer and the best base saturation for the radish crop, it was composed by eight treatments with four repetitions, totalizing thirty-two experimental unities, the treatments were: T1- %BS= 50%, with no fertilizer; T2- %SB= 80%, with no fertilizer; T3- %SB= 50%, mineral fertilizer; T4- %SB= 80%, mineral fertilizer; T5- %SB= 50%, wood ash fertilizer, T6- %SB= 80%, wood ash fertilizer; T7- %SB= 50%, organomineral fertilizer (50% mineral + 50% wood ash) and T8- %SB= 80%, organomineral fertilizer (50% mineral + 50% wood ash). The following variables were analyzed: plants height, culm diameter, leaves number, tuber diameter, tuber length, tuber and roots volume, water consumption and water efficiency use. The only variable that wasn't significant among the others was the leaves number, and the main effects of the fertilizers were observed with mineral and organomineral fertilizers. The best development of the radish crop occurred with a bases saturation at 80% with mineral or organomineral fertilizers.
