Abstract:
A pot culture experiment entitled Impact of inorganic nitrogenous fertilizers and FYM combinations on plant height at various phases of rice growth and combinations on number of tillers per hill at various stages of effective tillers per hill during rice harvest (Oryza sativa L.)” was conducted at Institute of Agricultural Sciences farm, Siksha ‘O’ Anusandhan (Deemed to be University), Bhubaneswar Odisha. on sandy loam soil during kharif 2018-2019. The experiment consisted of eight treatments viz. T1-Control, T2- 50% RDF, T3-50% RDF + FYM @ 5 t ha-1, T4-75% RDF, T5-75% RDF + FYM @ 5 t ha-1, T6- 100% RDF ( NPK 80:40:40), T7-100% RDF + FYM @ 5 t ha-1 and T8-150% RDF. The experiment was laid out in a Randomized Block Design with three replications. The results revealed that highest and significant values were recorded with respect to growth parameters i.e., plant height, number of tillers per hill, effective tillers per hill and yield attributes i.e., number of panicles per hill, panicle length, number of filled grains 1000 seed weight (test weight) in the treatment that received 100% RDF + FYM @ 5t ha-1. Combination of FYM (5 t ha-1) with lower levels of RDF (50 and 75% RDF) also registered higher increase in the above parameters as compared to the application of inorganic fertilizers alone with the corresponding levels. Grain and straw yields followed the same trend as that of growth parameters and at higher levels of nitrogen in the inorganic form (150 % RDF) the values of the various parameters including grain and straw yield were significantly lower than the treatment where 100% RDF +FYM @ 5 t ha-1was applied.. More nutrient content (N, P, K) in grain and straw was observed with the application of 100% RDF + FYM @ 5t ha-1 as compared with 100 and 150% RDF. With the combined application of 100 percent RDF as an inorganic source and 5tha-1 FYM as an organic source, improvements in physico-chemical characteristics such as organic carbon, bulk density, porosity, and accessible macro nutrients (N,P,K) were found.
