Table 2.

Biomass attributes of maize seedlings applied with various sources of sulfur fertilizers viz. K₂SO₄, FeSO₄, CuSO₄ and Na₂SO₄ at 0, 15, 30 and 45 kg ha⁻¹. Shoot length = SL, Root length = RL, Shoot fresh weight = SFW, Root fresh weight = RFW, Shoot dry weight = SDW and Root dry weight = RDW. Different alphabets represent significant difference between mean values ± standard error.
