“…Due to synergistic effect, application of silicon has potential to raise the optimum N rate, thus enhancing the production of existing lowland rice [31]. Rukhsana Jan et al [32] concluded from their two year study that the treatment combination with 120 kg N ha -1 and 15% Si proved to be the best as it produced highest grain yield.…”

Aim: Assess the effect of silicon and nitrogen application on chemical nutrition of plant and soil grown in Typic Ustifluvent soil Study design: Factorial RBD Place and duration of study: Field experiments was conducted in farmers holding in Kuttalam Block, Mayiladuthurai district. The experiment was conducted for two seasons Methodology: Field experiments was conducted in farmers holding during kuruvai and samba seasons to. The treatments consists of silicon levels viz., 0, 50,100 and 150 kg ha-1 and nitrogen levels viz., 0, 50,100, 150 kg ha-1. using rice as test crop var. ADT43 and CR1009.The grain and straw yield was recorded at harvest. The grain and straw samples were analyzed for nutrient contents and corresponding uptake was calculated. The soil samples were analyzed for nutrient status at different physiological stages. Results: The result revealed that graded doses of nitrogen and silicon applied alone or in combination caused significant improvement in rice yield over control. The rice yield reached its pinnacle (5600, 6786 kg ha-1) and straw yield (6811, 8031 kg ha-1) was noticed with 150 kg N ha-1 + 150 kg Si ha-1. However it was comparable with 150 kg N ha-1 + 100 kg Si ha-1 and 100 kg N ha-1 + 150 kg Si ha-1. The uptake increased with nitrogen and silicon levels. The highest nutrient uptake was recorded with 150 kg N ha-1 + 150 kg Si ha-1. It was comparable with 150 kg N ha-1 + 100 kg Si ha-1. Available nitrogen, phosphorus, potassium, and silicon increased with N and Si levels. The highest available N, P, K and Si was maximum when nitrogen and silicon was applied at 150 kg ha-1. Conclusion: Conjoint application of 150 kg N ha-1 and 150 kg Si ha-1 recommended to realize maximum yield of rice grown in soil low nitrogen and silicon
