Abstract The phenological development of one variety of
chickpea (
Cicer arietinum L. `Hernandez') was studied in Canterbury, New
Zealand using eight sowing dates in 1992-93 (July and September), 1993-94 (July
until November), and 1994-95 (October). The duration of all phases was
predicted based on thermal time above 4deg.C. For emergence to flowering (E-F),
photoperiod-corrected thermal time with a base photoperiod of 10 h was
calculated, but thermal time gave a better relationship with flowering rate.
The mean accumulated thermal times for the different phases were 133, 447, 761,
and 377deg.C days for sowing to emergence (S-E), E-F, flowering to mature pod
(F-MP), and mature pod to harvest maturity (MP-HM) respectively. An accurate
prediction of time to flowering was made based on an accumulated mean thermal
time requirement of 447deg.C days from E to F. The relationship between the
actual and predicted dates of flowering was highly significant
(
r2 = 0.983), and data from an independent source fitted the
model well.
