摘要

The objective of this study was to determine the effect of forcing summer asparagus (May-October) on yield, quality and recovery from harvest pressure. Ten-week-old seedlings of cv. UC 157 F1 were planted in the field in September 1986 and forced toemerge from 1988 to 1992 by mowing spring fern in separate replicated plots in May, June, July, August, September or October. Forcing treatments were not spring-harvested. Forced yields were compared with normal spring harvests (first emerging from January to March). Spring yields in 1988 were greatest of all, but declined yearly for 5 harvest years. Summer forcing in either July or August maintained acceptable yields through 1992. Forcing in May and June was too stressful and recovery ability and stands were reduced. Cooler temperatures during the October forcing inhibited spear emergence. Forcing in September yielded less than forcing in July and August, but September asparagus would command higher market prices.
