One hundred seeds of each of the 21 genotypes were plated in triplicate (300 seeds per treatment) on moist cotton and soaked with distilled water, Arnon Hoagland medium with or without nitrate, ammonium, or urea as the sole source of N. Percent germination in each plate was monitored every 3 h until all the seeds have germinated and the time taken for 50% seeds to germinate (t_½) were deduced for each replicate under different N regimes using X₀ function in SigmaPlot ver. 9 and subjected to two-way classified ANOVA. Mean values for all genotypes and all N treatments are categorized into statistically distinct classes as denoted by their superscripted alphabetic character. Values with different alphabets are significant at P < 0.05.
