INFLUENCE OF INTEGRATED USE OF FLY ASH WITH INORGANIC FERTILIZER AND FYM ON SOIL HEALTH AND YIELD OF RICE IN ENTISOL

摘要

A field investigation was carried out at farmer field, Gaitara, Raipur, Chhattisgarh during kharif season of 2013-14 to evaluate the impact of combined use of fly ash with inorganic fertilizer and FYM on soil health & yield of rice in Entisol. The result indicated that significant improvement of yield and yield attributes in terms of number of tillers hill~(-1) (6.32), effective tillers hill~(-1) (6.04), number of grain panicle~(-1) (95.47), test weight (24.02 gm), grain yield (42.11 q ha~(-1)) and straw yield (61.18 q ha~(-1)) were recorded with application of treatment 75% GRD + 40 t Fly ash ha~(-1) + 5 t FYM ha~(-1). Treatment 75% GRD + 40 t Fly ash ha~(-1) + 5 t FYM ha~(-1) significantly increased available nutrient status in terms of N (159.52 kg ha~(-1)), P (3.52 kg ha~(-1)) and K (239.75 kg ha~(-1)) in soil.
