Abstract

Background: A study was carried out during kharif season of 2021. Field experiment was laid out in a randomized block design having 8 treatments which were randomized thrice viz. T1-Control; T2-100% RDF (100:60:40 N: P2O5:K2O kg ha-1); T3 -75% RDF + 25t/ha Fly ash; T4-75% RDF + 25t/ha Fly ash + 5t/ha FYM; T5-75% RDF + 30t/ha Fly ash; T6-75% RDF + 30t/ha Fly ash + 5t/ha FYM; T7- 75% RDF + 45t/ha Fly ash; and T8 -75% RDF + 45t/ha Fly ash + 5t/ha FYM. The results showed that application of fly ash with fertilizer and FYM could be viable source for increasing the production of crops under degraded land conditions. The experiment resulted a significant effect on the soil enzymatic activity viz. dehydrogenase (47.21 µg TPF 24 hr-1g-1 soil), urease (38.65 μg NH4+- N g-1 soil h-1), acid phosphatase (27.41µg p-nitrophenol g-1 hr-1) and alkali phosphatase activity (69.54µg p-nitrophenol g-1hr-1) which were found highest with the 75% RDF + 45t/ha Fly ash + 5t/ha FYM. Overall result concluded that use of 75% RDF + 45t/ha Fly ash + 5t/ha FYM can save 25% of fertilizer (NPK) and increase the soil biological activity. N, P, K were significantly enhanced with the incorporation of fly ash with FYM whereas there was no effect on content of micronutrients (Fe, Mn, Zn,Cu) in soil.

Keywords: Fly ash, farm yard manure, dehydrogenase, urease, acid and alkali phosphatase
