Fig. 2. Differences in germination percentage between treatments: (H2SO4 18%)=
pre-treatment of seeds with 18% sulphuric acid for 20 min, (H2SO4 50%)=
pre-treatment of seeds in 50% sulphuric acid for 20 min, (EM 1%)= pretreatment
of seeds in 1% effective micro-organisms for twenty-four (24) h, (EM 2%)=
pre-treatment of seeds in 2% effective micro-organisms (EM) for twenty-four
(24) h and (Untreated)= soaking seeds in water only for 24 h to serve as the
experiment's control. Bars with different letters are significantly different
according to the least significant difference (LSD).
