Enhancement of agronomic traits and yield of rice var. ADT 43 grown in typic ustifluvent soil through silicon fertilization

Rice is a rich accumulator of silicon and its supply essential for the growth economic yield rice. Hence, field experiment was conducted in sandy clay loam soil belonging to Padugai series (Typic ustifluvent) at farmers holding Kuttalam block, Mayiladuthurai district, Tamil Nadu assess role improving agronomic characters rice ADT 43, Oryza sativa. The treatments included T1 - Recommended dose fertilizer (RDF), T2 RDF + Potassium silicate (FS) 0.25%, T3- FS 0.50%, T4 +FS 1.00%, T5­ -RDF T6 T7­ T8 SA 50 kg ha-1, T9 100 ha-1 T10 SA- 150 ha-1. From T4, foliar spray done tillering stage from T5 T7, panicle initiation stage. applied through with crop. application relatively recorded higher compared application. Besides different rice, Si registered highest grain (6183.3 ha-1) straw (6740 comparable single 1% Si. Growth increased concentration 0.25% 1%. Thus, @50 potassium advocated realize maximum yield.
