Integrated effect of inorganic and organic fertilizers with fly ash on total micronutrients uptake by rice crop

Abstract

The present investigation entitled “Influence of integrated effect of inorganic and organic fertilizers with fly ash on total micronutrients uptake by rice crop in acid soil of northern hills zone (C.G.)” was carried out during kharif season of 2014-15 at Ajirma village, Surajpur district (Chhattisgarh). The treatments comprised of control, 100% GRD (100:60:40), 75% GRD + 20 t fly ash ha-1, 75% GRD + 40 t fly ash ha-1, 75% GRD + 60 t fly ash ha-1, 75% GRD + 20 t fly ash ha-1 + 5 t FYM ha-1, 75% GRD + 40 t fly ash ha-1 + 5 t FYM ha-1 and 75% GRD + 60 t fly ash ha-1 + 5 t FYM ha-1 were laid out in Randomized Block Design (RBD) with three replications. The total iron, manganese, zinc, and copper (4141.21, 245.80, 123.05 and 32.96 g ha-1,) uptake was found in T8 (75% GRD + 60 t fly ash ha-1 + 5 t FYM ha-1) where it was minimum (2178.72, 115.04, 50. 99 and 9.72 g ha-1) in control.
