Note: T1-CF0, T2-100% CF, T3-60% CM + 40% CF, T4-30% CM + 70% CF, T5-60% PM+ 40% CF, T6-30% PM + 70% CF, CF—Chemical fertilizer, CM—cattle manure, PM—poultry manure, BD—Bulk density, SOC—Soil organic carbon, TN—Total nitrogen, AN—Available nitrogen. Values followed by the same letters, within column are statically same at p ≤ 0.05. The mean comparison were made using tukey tests for treatments mean in both seasons and the lettering was done on basis of Tuky HSD test at 5% using simple effect. ns = non-significant
*, ** = significant at 5% and ** at 1%, respectively.
