The effect of temperature and crown size on asparagus yielding
Gąsecka, Monika | Krzesińsk, Włodzimierz | Stachowiak, Jerzy | Knaflewski, Mikołaj
In order to determine the effect of temperature on asparagus yielding in the case of different crown sizes, asparagus plants were planted in growth chambers, in an aeroponic system with recirculation. The results show that asparagus yield was dependent on air temperature and crown size; however, crown size had a greater influence on the yield. The diameter and weight of the asparagus spears were also dependent on crown size. Higher dry weight content, degrees Brix, fructan and total carbohydrate content in storage roots were documented in large crown asparagus plants before and after harvest. Large sized crowns were also shown to build thicker and higher ferns.
