2.3. Mulching treatments
Five mulching [farmyard manure (FYM)] treatments were applied as follows: 0 ton ha−1 (FYM0) as a control, 10 ton h−1
was spread on the soil surface or incorporated with surface layer
(FYM10s or FYM10m) as a second or a third treatment, respectively.
In addition, 20 ton ha−1 was spread on the soil surface or incorporated
with surface layer (FYM20s or FYM20m) as a forth or fifth treatment, respectively.
The chemical analysis of the used FYM is shown in Table 2.
