ABSTRACT
The present Investigation were carried out on field grown two cultlvars of pigeonpea i.e. H-77-216 (Indeterminate) and ICPL-151 (determinate) type during the years 1989–90, to study the extent, pattern, intensity and periodicity of flower production and shedding. Total number of flowers, shed per plant were more in cv. H-77-216 (81.0%) than cv. ICPL-151 (77.6%). Maximum production and shedding of flowers were observed on 7th and 4th branch in cv. H-77-216 and ICPL-151, respectively. The Intensity of flower shedding was maximum within 24 hours of anthesls and declined subsequently with flower age. Likewise night period enhanced the flower shedding in both the cultlvars. In terms of periodicity the two cultlvars behaved almost similarly for flower production and shedding. The production and shedding of flowers were correlated with environmental factors.
