INFLUÊNCIA DA PULVERIZAÇÃO DE SILICIO NAS CARACTERÍSTICAS AGRONÔMICAS DA COUVE-FLOR (Brassica oleracea var Botrytis)NO SUDESTE GOIANO.

Abstract

Abstract – Cauliflower (Brassica oleracea var botrytis) is among the most cultivated and consumed vegetables in Brazil, being one of the main cultivated brassicas. The objective of this work was to evaluate the effects of silica fertilization on the quality and post-harvest yield of the Sharon cauliflower. The experiment was conducted in the municipality of Urutaí - Goiás, from October to December 2016, in a commercial vegetable garden. The experimental design was completely randomized (DIC), with 4 treatments and 3 replicates. Eight seedlings per plot were used, with the criterion of planting uniformity of size. The treatments applied corresponded to the following doses of silicon: 0 mg L-1 (T1), 20, 0 mg L-1 (T2), 30, 0 mg L-1 (T3) and 40, 0 mg L-1 (T4). The parameters evaluated were: number of leaves (NF) stem length and diameter (cm), inflorescence diameter (cm), complete cauliflower weighing (kg), inflorescence weighing (kg) and post-harvest quality of cauliflower through a scale of notes. The results indicate that there was no influence on the agronomic performance of the cauliflower; however, it is possible to observe an improvement in the post-harvest quality of the cauliflower from the silica fertilization via the leaf, justifying its use and the accomplishment of studies Later.
