A field experiment was carried out during Kharif 2016 at the Main Agricultural Research Station, University of Agricultural Sciences, Dharwad to investigate the effect of staggered sowings and application of additional dose of nitrogen to late parent on synchronization of male and female parents of pearl millet hybrid BPMH-3. The field experiment comprised of twelve treatments with three replications in split plot design. The results revealed that staggered sowing of male parent nine days earlier than female (S4) took less number of days for 50 per cent flowering in male (66.33 days) and also recorded the highest seed set per cent (78.10 %), test weight (9.90g) and seed yield per plant (21.01g) compared to other staggered sowings. On the other hand simultaneous sowing of female and male parent recorded the lowest values for growth parameters and it took more number of days to 50 per cent flowering (S1:67.44) and recorded least seed set percent, test weight and seed yield per plant viz. 61.08%, 7.04g and 18.43g respectively. With respect to application of additional dose of nitrogen (N), recommended dose of fertilizer (N0) recorded least seed set percent, test weight and seed yield per plant (62.77%, 8.00g and 18.82 g respectively). While, N2: Application of additional N @ 10 kg ha-1 at 35 DAS to late parent recorded less number of days for fifty per cent flowering (65.92days) and the highest seed set percent (73.26%), test weight (8.68g) and seed yield per plant (20.53 g). Further the combination of staggered sowing of male parent by nine days earlier than female parent coupled with the application of additional dose of nitrogen @ 10 kg ha-1 at 35 days after sowing to male parent (N2), decrease the difference in flowering between female and male parent to -0.74 days (S4N2) from 11.00 days (S1N0). This revealed that sowing of male parent nine days earlier than the female parent and application of additional 10 kg N ha-1 to male parent at 35 days after sowing was appropriate to achieve nicking between female and male parental lines of pearl millet hybrid, BPMH-3.
