Abstract
The present investigation was carried out to study the influence of staggered
sowing of male parent on synchronization of flowering with the female parent on seed
set, seed yield and seed quality of pearl millet hybrid MH-946 (GHB -558) and split
application of nitrogen on synchronization of flowering on seed set, seed yield and
seed quality of pearl millet hybrid MH-946 (GHB-558) parents.
Male parent flowered late by eight to ten days than female with simultaneous
sowing. Among the different techniques to achieve synchronization of flowering,
Sowing of male parent by 8 days earlier to female along with 50% N at the time of
sowing + 25% N at 25 DAS + 25% N at 35 DAS to male parent resulted in better
synchronization of flowering (1.34 days) and resulted in significantly highest seed
yield (2273.6 kg/ha) over simultaneous sowing (868.3 kg/ha). This treatment also
hastened the days to 50 %flowering in male parent (52.0 days) and increased the ear
weight (28.3 g/ plant), number of seeds per ear (2658), seed weight per ear (21.0 g),
seed set % (91.6), and 1000 seed weight (11.2 g) compared to other treatments.
The results of another field experiment conducted during 2011, to study the
effect of date of sowing on flowering behavior of parental lines of MH-946 (GHB-
558) pearl millet hybrid revealed that, sowing dates influenced the flowering behavior
of the parental lines. Sowing at end of July caused early initial and 50% flowering by
4 days between female and male parents. None of the sowing did not give cent per
cent synchrony and the flowering difference (50%) ranged from 4 to 10 days during
June 1st week to July 4th week under Bijapur condition.
