Changes in the activity of sucrose (SS) enzyme during early (A) and late-season (B) and adenosine diphosphate glucose (AGPase) during early (C) and late season (D) in rice grains under the combination organic and inorganic N fertilization. Vertical bars represent the standard error of the mean. The mean comparison was made using least significant differences (LSD) test for treatments and seasons means based on the LSD test at 5%. ns = non-significant and *^,** = significant at 5% and 1%, respectively. Note: T₁— no N fertilizer, T₂— 100% CF, T₃—60% CM + 40% CF, T₄—30% CM + 70% CF, T₅— 60% PM + 40% CF, T₆—30% PM + 70% CF. Note: CF—chemical fertilizer, CM—cattle manure, PM—poultry manure.
