Description |
The present investigation entitled “Effect of graded dose of fly ash applied with and without FYM onrice productivity, microbial and enzymatic activity of soil” was carried out during kharif season of 2015-16 at Gaitara village, Tilda block, Raipur District (C.G.). The field experiment was laid out in Randomized block design with three replications and eight treatments namely control, 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. Rice variety “MTU 1010” was transplanted on 2 August, 2015 with row spacing of 15 × 10 cm. The soil of the experiment washaving normal pH, low in nitrogen, phosphorus and medium in potassium. Results revealed that increased soil microbial and enzymatic activities was observed by the application of graded dose of fly ash with and without FYM. Graded doses of fly ash was integrated with 75 % of recommended fertilizers and 5 t ha-1 FYM imprinted positive effect on crop yield and trended to improve soil fertility status as compared GRD. The highest grain and straw yield was recorded by application of 75% GRD + 40 t fly ash ha-1 + 5 t FYM ha-1, (T7) treatment. |
