Resumo: Water deficit in cauliflower cultivation may impair its development and yield. This study aimed to analyze the agronomic performance of cauliflower grown in a protected environment, under different water conditions and silicon (Si) doses. The experiment was arranged in a randomized block design, in a 3 x 4 factorial scheme, with three levels of water replacement [40, 70 and 100 % of the evapotranspiration (ETc)] and four Si doses (0, 50, 100 and 150 kg ha-1), with four replications. Leaf (SPAD index, area, fresh and dry weight), stem (diameter, height, fresh and dry weight) and inflorescence (diameter, fresh weight, dry weight, water content and commercial classification) characteristics were evaluated. The replacement of 40 % of the ETc showed lower results for the SPAD index in the phases II and III, leaf area, leaf and stem fresh weight and inflorescence diameter. The 70 % replacement cultivation showed a yield similar to that of the 100 % of the ETc. The use of Si was beneficial for the productive performance of the cauliflower at all levels of water replacement. KEYWORDS: Brassica oleracea var. botrytis, water stress, irrigation management.

Objetivou-se analisar o desempenho agronômico de couve-flor cultivada em ambiente protegido, em diferentes condições hídricas e doses de silício (Si). Utilizou-se delineamento em blocos ao acaso, em esquema fatorial 3 x 4, sendo três níveis de reposição hídrica [40, 70 e 100 % da evapotranspiração (ETc)] e quatro doses de Si (0, 50, 100 e 150 kg ha-1), com quatro repetições. Foram avaliadas características das folhas (índice SPAD, área, massa fresca e seca), do caule (diâmetro, altura, massa fresca e seca) e da inflorescência (diâmetro, massa fresca, massa seca, teor de água e classificação comercial). A reposição de 40 % da ETc apresentou menores resultados para o índice SPAD nas fases II e III, área foliar, massa fresca das folhas e do caule e diâmetro da inflorescência. O cultivo com reposição de 70 % apresentou produtividade semelhante à de 100 % da ETc. A utilização do Si foi benéfica para o desempenho produtivo da couve-flor em todos os níveis de reposição hídrica.
