  1. Values with similar lower-case letter within a column for each scenario are not significantly different at P < 0.05 according to Tukey’s HSD. CA2- Conservation agriculture followed for 2 years; CA4- Conservation agriculture followed for 4 years; CA8- Conservation agriculture followed for 8 years; CA12- Conservation agriculture followed for 12 years; CT- Conventional tillage.
