Effect of N on germination at the mean time taken for 50% seeds to germinate among 21 Indica rice genotypes. The mean time taken for 50% seeds to germinate (t½) in Arnon Hoagland media with or without N for all the 21 genotypes were plotted for each treatment, along with their standrad error values (error bars at Y1 axis). The extent of delay in germination caused by each N source relative to that observed in media without N is shown as an inset in each bar using an expanded scale on the Y2 axis. The data are categorized into statistically distinct classes as denoted by alphabetic character for each set of bars (red and blue). Bars with different alphabets are significant at P < 0.05.
