Abstract
A field experiment to study the “Effect of fly ash, phospho-gypsum and chemical fertilizers on soil properties and nutrient uptake, growth and yield of wheat (Triticum aestivum L.)” was conducted at farmer’s field during Rabiseason during the years 2014-15 and 2015-16. The treatments were consisted 15 combinations of fly ash and phosphogypsum was laid out in randomized block design with three replications.The application of 75% RDF + 15 t FA ha-1 + 2 t PG ha-1 significantly enhanced the yield attributes, seed, straw and biological yield, chlorophyll, content and uptake of N, P, K, Ca, Mg and S in seed and straw, protein, total sugar and starch content of seed and straw of crop during both the years and in pooled analysis.The results revealed that incorporation of 75% RDFwithfly ash and phosphogyspum decreased bulk density whilewater holding capacity, urease, dehydrogenase activity, alkaline phosphatase, electrical conductivity, pH, CEC and organic carbon, available N, P, K, Ca, Mg and Scontent of soil at harvest of crop were increased during both the years and in pooled mean.
