REAL-ROSAS, Marco A et al. Variedades precoces de brécol para la diversificación agrícola en zonas áridas. INCI [online]. 2002, vol.27, n.5, pp.247-251. ISSN 0378-1844.

Five broccoli varieties were grown under arid conditions in order to compare yield, head quality and precocity. The highest yield was obtained in Ryokurei with 6.8 ton/ha which was achieved by a significant increase of head fresh weight and compactness in comparison with other varieties. However, Ryokurei seeds are produced in Japan, whereby seed availability in local markets is an obstacle which must be overcome. The Galleon variety manifested the highest precocity among evaluated varieties and its head harvest began 7 days before compared to other varieties, and only needed two harvests to accumulate 6 ton/ha, while Ryokurei needed four harvests to produce 6.8 ton/ha. From these results, the Galleon variety is recommended to grow in arid areas because its precocity allows it to save water and the seed is easily found in local markets.
