Abstract:
In the present study, among different inoculation technique at four levels of Urocystis agropyri inoculum load, the maximum flag smut incidence (58.18%) was recorded in inoculation of germinating seed with dry inoculum @ 10 g inoculum/ kg seed followed by its 7.5 g inoculum/ kg seed (55.65%) and inoculation of seed with germinating inoculum at 10 and 7.5 g inoculum/ kg seed with 53.76 and 51.11 per cent, respectively and the least incidence (5.30%) in inoculation of germinating seed with germinating inoculum @ 2.5 g inoculum/ kg seed. However, within effect of inoculum load on seed health parameters, the highest inoculum load of 20 g inoculum/ kg seed showed maximum reduction on seed germination percentage (13.70%), seed vigour index (52.96%), seedling growth rate (54.41%) and seedling dry weight (6.73%) except speed of seedling germination i.e. maximum at 17.5 g inoculum/ kg seed. Yet, the least reduction in each case was noted at 5 g inoculum/ kg seed.
