| dc.description.abstract | The present investigation was carried out to study the influence of seed treatment with hydration, gibberellic acid and soil application of additional nitrogen in combination with urea spray to female parent (CI-4) and only Abcisic acid seed treatment to male (KDMI-10) on synchronization of flowering between the parental lines, seed yield and quality of hybrid maize DMH-2 at MARS, UAS Dharwad during kharif 2010. Female parent flowered late by six days than male with simultaneous sowing. Among the different techniques to achieve synchronization of flowering, pre sowing seed hydration(6hrs) + 10 % additional N soil application to female parent resulted in better synchronization of flowering (1.34 days) and resulted in significantly highest seed yield (38.33 q/ha) over simultaneous sowing control (23.07 q/ha). This treatment also hastened the first flowering in female parent (47.33 days) and increased the cob length, cob weight (163.00 g/ plant), number of seeds rows per cob (14.00), seed weight per cob (132.07 g), seed set % (96.45), 100 seed weight (29.79 g) and fodder yield (3.33 q) compared to other treatments. The results of another field experiment conducted during 2010-11, to study the effect of time of sowing on flowering behavior of parental lines of DMH-2 maize hybrid revealed that, sowing dates influenced the flowering behavior of the parental lines. Sowing in mid July caused early initial and 50% flowering by 4 days and 3 days between female and male parents respectively and the difference was gradually increased up to January 1st sowings. None of the sowing did not give cent per cent synchrony and the flowering difference (50%) ranged from 3 to 11 days during June 1st 2010 to January 15th 2011 under Dharwad condition. | en_US |
