Emissions of panel (A) NH₃, (B) CO₂, and (C) CH₄ from arable land after co-application of zeolite and biochar along with chemical fertilizers. Error bars represent the standard error (±) of the mean. Data bars of each parameter having dissimilar small or capital letters differed significantly from each other (P ≤ 0.05). The inset table indicates the analysis of variance (ANOVA). Multiple comparisons among treatments were analyzed by LSD test. C = control, Z = zeolite @ 5 t ha^{– 1}, B1Z = biochar @ 3 t ha^{– 1} + zeolite @ 5 t ha^{– 1}, B2Z = biochar @ 6 t ha^{– 1} + zeolite @ 5 t ha^{– 1}, B3Z = biochar @ 9 t ha^{– 1} + zeolite @ 5 t ha^{– 1}.
