Fig. 2.

Fluorescein diacetate hydrolases (FDH) (μg fluorescein g⁻¹ soil hr⁻¹) and Aryal sulphatase activity (μg p-NP g⁻¹ soil hr⁻¹) in rhizosphere and bulk soils at maximum tillering stage of crop under different tillage, residue and crop rotations.

Where, R: rhizosphere; ARS: aryal sulphatase activity; FDH: Fluorescein diacetate hydrolases activity.

Same upper case letters among the CSA systems and same lower case letters between rhizosphere and bulk soils in each system are not significantly different at P < 0.05 according to Duncan Multiple Range Test (DMRT) for separation of mean.
