The present study was conducted at the Field Laboratory of the Department of Agriculture, Noakhali Science and Technology University (NSTU), Noakhali-3814, from December 2022 to May 2023 to investigate the effect of vermicompost on the growth, yield, and nutritional content of boro rice. This field experiment consisted of the BRRI dhan97 and four vermicompost (VC) treatments viz. T0 (Control), T1 (vermicompost 3 t/ha), T2 (vermicompost 4 t/ha), T3 (vermicompost 5.5 t/ha). The experiment was arranged in a randomized complete block design (RCBD). It was found that vermicompost have a significant effect on the number of grains/panicles and nutritional value (moisture %). The highest plant height (136.84cm), grain/panicle (114.04), thousand-grain weight (27.9gm), grain yield (6.32 t/ha), panicle length (27.893cm) were observed for T3 (vermicompost 5.5 t/ha) and these are 1.49 %, 31.98 %, 5.006 %, 24.17%, 0.79 % higher than control. The total number of tiller/hill (15.56), and straw yield (7.74 t/ha) were highest for T2 (vermicompost 4 t/ha) which are 10.59 %, 30.41 % higher than control. Nutritional value (protein) (3.73) was highest for T1 (vermicompost 3 t/ha) which is 26.80 % higher than control. Harvest index (46.51%) and moisture content (4.85 %) was highest for control. Vermicompost treatment (5.5 t/ha) provided 6.32 t/ha grain yield which was the highest compare to other treatments.
