Field experiment was conducted with two different varieties of rice (Oryza sativa L.) namely, Pooja grown in kharifseason followed by MTU-1001 grown in rabi season. The experiment consisted of nine different treatments, one with recommended dose (RD) of nitrogen, phosphorous, potassium (NPK) fertilizer served as the control and the rest of the treatments were either lone fly ash (FA) or FA applied in two doses in combination with different amounts of fertilizers (100% RD or 50% RD of NPK) and farm yard manure (FYM). Except for the lone FA doses the rest of the treatments were found to have varying degrees of beneficial effects on grain yield over the control without affecting the protein contents. The most effective dose was RD + FA @ 40t ha−1 for both the seasons. The increase in the quantities of FA from 20t ha−1 to 40t ha−1 did not changed the protein contents of the grains significantly. Again no significant cumulative effect of the amendments could be observed in the second season.
