abstract={Field experiments were carried out during kharif season of 2017 and 2018 to evaluate the effect of integrated use of lignite fly ash (LFA) with organics and fertilizers separately or in combinations on growth, yield parameters, yield and nutrient uptake of rice (<i>Oryza sativa</i> L) in Vertisol. The results revealed that incorporation of 10 t LFA ha<SUP>-1</SUP> alone or in combination with organics plus fertilizers was most effective in enhancing the growth, yield attributes, rice yield and nutrient uptake over control. Interaction effect between LFA and fertilizers was realized in straw and nutrient uptake only. Application of 10 t LFA ha<SUP>-1 </SUP>caused 6.2, 6.6 % (grain yield), 5.5, 12.4% (straw yield) over no LFA in 2017 and 2018, respectively. Among conjoint application of organics and fertilizers, addition of 100 % NPK +10 t SPM ha<SUP>-1</SUP> recorded the maximum grain (6.89, 6.92 t ha<SUP>-1</SUP>) and straw yield (8.26, 8.44 t ha<SUP>-1</SUP>) during 2017, 2018 respectively, besides growth and yield attributes. In the presence of LFA, grain and straw yield improved further with all the fertilizer treatments. Addition of RDF or combination with organics resulted in higher uptake and interaction with LFA was significant and the maximum nutrient uptake were noticed with 100 % NPK + SPM + LFA of 122 and 127 (N), 35 and 39 (P), 97 and 103 kg ha<SUP>-1 </SUP>(K) in 2017and 2018, respectively.},
