Abstract

Most bean varieties (Phaseolus vulgaris) are susceptible
to zinc deficiency and, if grown where
zinc deficiency occurs, are invariably listed among
those crops with the greatest need for zinc fertilization
(1, 2, 3, 4). Bean plants with mild to moderate zinc deficiency
symptoms early in the growing season may
recover and produce essentially a normal yield. However,
as several individuals have observed (1, 2, 3)
this early-season zinc deficiency invariably results in
delayed maturity. This is a critical factor in geographical
areas where beans may be damaged by fall
rains or early frost.
The research reported here establishes quantitative
relationships between the zinc level in bean tissues
and the number of days required for maturation. The
results support previous observations of delayed maturity
when bean plants have inadequate zinc during
early growth.
