Integrated use of organic and inorganic sources of nutrients on growth and yield of rice (Oryza sativa L.)

Author(s): A Rajesh Kumar and M Balusamy
Abstract: Field experiments were carried out at Tamil Nadu Agricultural University, Coimbatore, Tamil Nadu, to study the effect of different sources of organic manures in comparison with different level of recommended dose of fertilizer on growth and yield of rice during rabi season of 2015-16 and 2016-17. The experiments were laid out in split plot design and replicated thrice. Main plot treatments were assigned with five levels of organic manures namely, silt from fish pond fed with desi poultry dropping @ 5 t/ha + vermicompost @ 5 t/ha (M1), silt from fish pond fed with duck dropping @ 5 t/ha + vermicompost @ 5 t/ha (M2), silt from fish pond fed with turkey dropping @ 5 t/ha + vermicompost @ 5 t/ha (M3), farm yard manure @ 12.5 t/ha (M4) and no manure application (M5) and 100% RDF (S1), 75% RDF (S2) and no fertilizer application (S3) were assigned to sub plot treatments. Among the growth and yield contributing characters studied, plant height, productive tillers/m2, panicle length and filled grains/panicle were varied significantly by the different treatments. Most of the growth and yield contributing characters influenced positively in treatment having organic manures over recommended dose of fertilizer. The highest grain yield (6783 and 7122 kg/ha) and straw yield (8177 and 8618 kg/ha) were recorded in application of farm yard manure 12.5 t/ha in combination with 100% recommended dose of fertilizer (M4S1) over rest of the treatments during both the years.
