A field experiment was conducted during 2013-14 at Agricultural Experimental Farm of Calcutta University at Baraipur, 24-Paraganas (south), Kolkata to study the effect of micronutrient on yield and yield attributes of hybrid rice under boro cultivation in lower gangetic alluvial zone. NPK (40/120:60:60) + ZnSO4 + Ammonium molybdate + Di-sodium-tetrahydrateoctaborate as foliar application at active tillering stage and panicle initiation stage respectively of hybrid rice crop growth have profound influence on the yield parameters such as grain yield (6.54t/ha), straw yield (6.79 t/ha) and biological yield (13.33 t/ha). Harvest index (49.07) was higher in NPK (40/120:60:60) + Ammonium molybdate + Di-sodium-tetrahydrateoctaborate. The yield attributing characters such as no. of panicles m-1 (10.838) and filled grains panicle-1 (99.00) were higher in the same treatment although no. of unfilled grains panicle-1 (15.00) was less as compared to others. Length of panicle (27.50 cm) and total no. of grains panicle-1 (120.33) were increased due to NPK (40/120:60:60) +ZnSO4+ Ammonium molybdate at active tilleringstage. Test weight (22.35 g) was higher in NPK (40/120:60:60) +ZnSO4 + Di-sodium-tetrahydrateoctaborate applied in panicle initiation stage.
