Abstract
Field experiment was conducted to study the effect of silicon on vegetative growth and root characteristics of rice during Kharif season during (July-Nov2019) at Department of Agronomy, Annamalai University, Tamil Nadu, India. The experiment was laid out in split plot design with two replications. The main plots comprised of M1- Dry Seeded Rice (DSR), M2- Wet Seeded Rice (WSR) and M3- Transplanted Rice (TR) and sub plots are S1- RDF, S2 - S1 + 100 kg Si ha-1 through Calcium Silicate + Silicate solubilising bacteria (SSB), S3 - S1 + 200 kg Si ha-1 through Calcium Silicate + SSB, S4 - S1 + 100 kg Si ha-1 through Diatomaceous Earth, S5 - S1 + 200 kg Si ha-1 through Diatomaceous Earth, S6 – S1 + 100 kg Si ha-1 through Fly ash + SSB and S7 – S1 + 200 kg Si ha-1 through Fly ash + SSB. Among the methods of rice establishments, transplanted method registered higher vegetative growth (plant height, number of tillers, chlorophyll content, leaf area index and dry matter production) and root characteristics (root length and root volume) of rice, which was followed by wet seeded rice, With respect to silicon sources and its levels, application of 200 kg Si ha-1 through Diatomaceous Earth along with RDF recorded higher vegetative growth (plant height, number of tillers hill-1, chlorophyll content, leaf area index and dry matter production) and root characteristics (root length and root volume) of rice. This was closely followed by 100 kg Si ha-1 through Diatomaceous Earth along with RDF. The interaction effect between establishment methods and silicon was significant. The treatment combination of Diatomaceous Earth @ 200 kg Si ha-1 earth along with RDF and transplanted method registered its superiority over others and recorded higher vegetative growth (plant height, number of tillers hill-1, chlorophyll content, leaf area index and dry matter production) and root characteristics (root length and root volume) of rice. Thus it can be concluded that silicon fertilization through Diatomaceous Earth @200 kg Si ha-1 + RDF to transplanted rice holds immense potentially to enhance the vegetative growth of rice.
