Abstract

Faced with the water crisis in the semi-arid region and the competitiveness of modern agriculture, the efficient use of water becomes a fundamental tool for the sustainability of irrigated production systems. The objective of this work was to evaluate the effects of irrigation depths on the development of beet cultivars in the Submédio São Francisco region. An experiment was carried out in the experimental field of Bebedouro, Embrapa Semiárido, in the municipality of Petrolina-PE. The experiment was carried out in a randomized block design in subdivided plots with five plots of irrigation (50, 75, 100, 125 and 150% of crop evapotranspiration (ETc)) and subplots three beet cultivars (Rubios, Scarlet Super and Early Wonder), with four replicates. Biometric characteristics were evaluated: leaf numbers, leaf length and width, root diameter and length, as well as total and commercial productivity and average shoot weight. The cv Rubios presented higher total and commercial productivities, being the irrigation blade with 125% of ETc and a greater efficiency of water use than the others.
