Integrated Effect of Fly ash, Organic Additives and Fertilizers on Yield and Uptake of Rice (Oryza sativa L.)

K. Theresa | S. Vijayakumar [2]


Abstract: Investigation into the effect of fly ash in combination with three organic manures viz. , Farm yard manure (FYM), green leaf manure (GLM) and Humic acid (HA) and inorganic fertilizers on the yield and uptake of rice was studied. The test crop was rice variety (ADT 49). Field experiment was conducted during 2014-15 in Krishi Vigyan Kendra, Tirur. Fly ash generated from Mettur Thermal Power Station was selected for the study and examined for its physical and chemical properties. Analysis of fly ash revealed that it is neutral to alkaline (pH 8.1) in reaction. The results confirmed that fly ash contains all the essential elements required for the plant growth as that of soil except organic carbon and nitrogen. It was observed that fly ash (@ 20 t ha-1) + GLM (@ 6.25 t ha-1) with RDF (1505050) supported maximum growth, yield and uptake. The treatment which received fly ash + GLM with RDF (1505050) recorded the highest grain (5.49 t ha-1) and straw yield (6.59 t ha-1). The highest nutrient uptake by the grain and straw were observed under the treatment of fly ash+ GLM with RDF. Thus the integrated effect of fly ash, manures and fertilizer was well pronounced in improving the productivity of rice.
