The Effects of Organic Manures and Silicon Nutrition on the Productivity of Rice

Abstract

A field experiment was carried out during the Samba season of 2022-2023 at the Experimental Farm, Department of Agronomy, Annamalai University, Tamil Nadu, to study the effect of organic manures and silicon nutrition on the productivity of rice. The treatments comprised of T1 – Recommended dose of fertilizers (RDF) (150:50:50 kg NPK ha-1), T2 – RDF + Farm Yard Manure (FYM) @ 12.5 t ha-1, T3 – RDF + Green manure (GM) @ 6.25 t ha-1, T4 - RDF + Poultry manure (PM) @ 2 t ha-1, T5 – RDF + FYM @ 12.5 t ha-1 + PM @ 2 t ha-1, T6 – RDF + GM @ 6.25 t ha-1 + PM @ 2 t ha-1 , T7 - RDF + FYM @ 12.5 t ha-1 + Si @ 200 kg ha-1 through Diatomaceous Earth (DE), T8 – RDF + GM @ 6.25 t ha-1+ Si @ 200 kg ha-1 through DE, T9- RDF + PM @ 2 t ha-1+ Si @ 200 kg ha-1 through DE, T10- RDF + FYM @ 12.5 t ha-1+ PM @ 2 t ha-1 + Si @ 200 kg ha-1 through DE, T11- RDF + GM @ 6.25 t ha-1+ PM @ 2 t ha-1+ Si @ 200 kg ha-1 through DE. The treatments were laid out in randomized block design and replicated thrice. Among the different treatments imposed, T11- RDF + GM @ 6.25 t ha-1 + PM @ 2 t ha-1+ Si @ 200 kg ha-1 through DE recorded the highest yield Root length (cm), Root volume (cc) of rice.
