Características morfológicas e produtivas do rabanete sob diferentes lâminas de irrigação

Abstract

Water stress throughout the crop cycle of the radish may interfere with its development, causing changes in the morphology, physiology, and the biochemical reactions of the plant. The objective of this work was to evaluate the development, morphological characteristics and productivity of the radish submitted to different irrigation slides during the crop production phase. The present work was carried out in the vegetable sector of the experimental farm of the UFMG campus in Montes Claros-MG, in the period of April and May. The experimental design was in a randomized block design, where 16 plots were assembled and from the 21-st day the plots were submitted to 4 treatments and 4 replicates each. These treatments consisted of four irrigation slides being 50%, 75%, 100% and 125% of ETo. The diameter of the stem (mm), diameter of the bulb (mm), weight (gram), temperature in ° C, number of leaves, height (cm) and chlorophyll content were evaluated. Irrigation slides did not present significant effects on the variables: leaf number, temperature, chlorophyll content and stem diameter. The height of the plant, the diameter and the weight of the bulb were increased with the Water Blade, being this linear relation. Therefore, irrigation blades had an increasing effect on development and productivity.
