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