Study on Assessment of Silicon and Nitrogen Fertilization on Plant and Soil Nutrition and Rice Yield Grown in Typic Ustifluvent Soil

The goal of this study is to see how silicon and nitrogen treatment affects the chemical nutrition of plants and soil in Typic Ustifluvent soil.

Introduction: Nitrogen is an essential nutrient for plants, as it is required for photosynthesis, growth and development, rice yield, quality, and biomass. Silicon interacts well with other applied nutrients, improving their agronomic performance and yield response efficiency.

Factorial RBD was used in this study.

Study Location and Duration: Farmers in Kuttalam Block, Mayiladuthurai district, participated in field trials. For two seasons, the experiment was carried out.

Field tests were carried out in farmers’ fields during the kuruvai and samba seasons. The treatments include silicon levels of 0, 50, 100, and 150 kg ha-1, as well as nitrogen levels of 0, 50, 100, and 150 kg ha-1, using rice vars. ADT43 and CR1009 as test crops. At harvest, the grain and straw yields were recorded. The nutritional content of grain and straw samples was determined, and the associated uptake was computed. The nutritional level of soil samples was determined at various physiological stages.

The results showed that graded doses of nitrogen and silicon applied alone or in combination resulted in a considerable increase in rice production when compared to the control. With 150 kg N / ha + 150 kg Si / ha, rice yields peaked (5600, 6786 kg ha-1) and straw yields peaked (6811, 8031 kg ha-1). However, 150 kg N / ha + 100 kg Si / ha and 100 kg N / ha + 150 kg Si / ha were equal. The rate of absorption increased as nitrogen and silicon levels increased. With 150 kg N / ha + 150 kg Si / ha, the maximum nutrient absorption was reported. It was similar to 150 kg of nitrogen per hectare and 100 kg of silicon per hectare. With higher N and Si levels, available nitrogen, phosphorus, potassium, and silicon increased. When nitrogen and silicon were sprayed at 150 kg/ha, the greatest available N, P, K, and Si were obtained.

Conclusion: For maximum yield of rice grown in low nitrogen and silicon soils, a combined application of 150 kg N/ha and 150 kg Si/ha is advised.
