Abstract
Rice, a key staple crop worldwide, is highly vulnerable to lodging, particularly when cultivated for high yields. Although both Nitrogen (N) and Silicon (Si) are known to influence plant growth and structural integrity, their combined effects on enhancing grain yield and reducing lodging have rarely been examined in field-based studies. This study analyzed the effect of nitrogen and silicon fertilizers on rice yield and lodging resistance for rice stem ensuing from farmer holding rice field during kharif 2025. The treatments consists of viz., T1 - No RDF (Control), T2 - Farmers practices, T3- 100% RDN, T4- 75% RDN, T5 - 50 % RDN, T6- 50% RDN +150 kg of Silicon ha-1, T7 - 75% RDN + 150 kg of Silicon ha-1, T8 - 100% RDN +150 kg of Silicon ha-1. The test crop was rice var. ADT 59. The results showed that the significantly increasing rice yield and resistance to lodging in the application of 75% RDN + 150 kg of Silicon ha-1 in over control.
