Answer: Only 2, 3, 4 & 5
Notes: Mulching contributes to moisture conservation, improves soil structure, increases soil fertility, and helps in control of pests, corresponding to statements 2, 3, 4, and 5. However, it may inhibit seed germination as it can lower soil temperature and reduce direct soil-soil contact needed by seeds. Hence, statement 1 is not correct.
