Changes in the activity of soluble starch synthesis (SSS) enzyme during the early (A) and late-season (B) and granule bound starch synthesis (GBSS) during the 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 the 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.
