Field experiments were conducted in two seasons in farmer’s field in Typic Ustifluvent soil to assess the impact of silicon nitrogen interactions on physiological traits of lowland rice. The treatment consists of factor A- N levels (0, 50, 100 and 150 kg/ha) and factor B- Silicon levels (0, 50,100,150 kg Si/ha)., totalling sixteen treatment combination laid out in Factorial RBD with three replications employing test crop Rice var. ADT 43 (kharif) and CR1009 (rabi) seasons Physiological traits viz., tiller count, chlorophyll, growth analysis viz., CGR, RGR, NAR, root density and rice yield. The results revealed that physiological traits were significantly improved by silicon or nitrogen alone or both over control. The physiological traits increased with nitrogen and silicon levels and the maximum value was recorded when both were applied at 150 kg/ ha each. Grains and straw increased linearly with increase in nitrogen and silicon levels. The highest grain yield was observed with 150 kg N/ha + 150 kg Si/ha (5600, 6786 kg/ha) in kuruvai and samba season respectively. It was comparable with 150 kg N/ha+ 100 kg Si/ha, and 100 kg N/ha + 150 kg Si/ha in kuruvai and samba seasons. The maximum straw yield was observed with 150 kg N/ha + 150 kg Si/ha (6811, 8031 kg/ha) in kuruvai and samba season respectively
