Abstract
A field study was conducted to evaluate the effect of establishment methods and integrated nutrient management practices on growth, yield attributes and yield of rice (Oryza sativa L.) was carried out during late samba season 2021 at the farmers field of Sadhurvedhamanagalm village, Sivagangai district. It was laid out in a factorial randomized block design, replicated thrice with two establishment methods (A1- Direct seeded rice (DSR) and A2-Transplanted rice (TPR)) as factor A and five INM practices (B1-RDFRecommended Dose of Fertilizer (120:40:40 kg NPK ha-1) alone, B2-RDF + Poultry manure compost @ 5 t ha-1, B3-RDF + Coir pith compost @ 5 t ha-1, B4-RDF+ Green manure (Daincha) @ 6.25 t ha-1 and B5-RDF-Green leaf manure @ 6.25 t ha-1) as a factor B. Among the establishment methods, transplanted method recorded highest growth attributes (plant height, leaf area index, number of tillers m-2 and dry matter production), yield attributes (number of productive tillers m-2, number of filled grains panicle-1) and yield (grain yield and straw yield) of rice. Similarly, among the different INM practices, the highest growth, yield attributes and yield were recorded under the treatment RDF+ poultry manure compost @5 t ha-1 than the other treatment combination.
