The commercial yield increase of asparagus is influenced by the perennial section size of plants commonly named spiders or crowns, which every year produce a greater number of shoots giving rise to commercial turions. The aim of the present work was to study the behavior at harvest of three green asparagus spider sizes. It started in Azul, Buenos Aires, on September 12, 2003. The following variables were evaluated: total fresh weight harvested and for each harvest, number of turions and thickness of each one, by means of USDA patterns defined for Asparagus officinalis. Treatments were performed on three spider sizes: G: large (>200 g), M: medium (100-200 g) and Ch: small (<100 g) with four repetitions. Plants derived from greater spiders achieved a significantly higher production (kg.ha-1 and number of turions). At the beginning of the productive stage, when plants still have enough reserves, their production is quite the same, but once most of the reserve is consumed, they start presenting significant differences according to its reserve capacity. A direct relationship was recorded between spider size for planting and yield (kg.ha-1). Over the first harvest year, a greater amount of medium turions was obtained, followed by small and large ones. [ABSTRACT FROM AUTHOR]
