초록
The study was conducted to observe the effects of compost of faecal sludge (FSC) and food waste (FWC) on seed germination and initial growth performance of Acacia auriculiformis and Swietenia mahagoni seedlings at the nursery of Chittagong University, Bangladesh. Before sowing the seeds, different combinations of FSC and FWC were incorporated with nutrient-deficient natural forest soils. Seed germination and growth parameters of seedlings were recorded after two, three and four month of seed sowing. We observed that seed germination (%) and seedlings growth parameters varied significantly (p＜0.05) in the soil added with FSC and FWC in comparison to control. The highest germination was observed 88.89% for A. auriculiformis in combination of soil and FSC at 3:1 and 92.59% for S. mahagoni where soil combined with FWC at 4:1. The seedling biomass and other growth parameters of A. auriculiformis and S. mahagoni was also observed with combinations of soil with FSC 3:1 and soil with FWC 4:1. Therefore, the study revealed that the compost of both FS and FW can be a good soil conditioner for the initial growth of forest seedlings and the proven combinations can help to grow quality seedlings in the nursery.
Abstract
The study was conducted to observe the effects of compost of faecal sludge (FSC) and food waste (FWC) on seed germination and initial growth performance of Acacia auriculiformis and Swietenia mahagoni seedlings at the nursery of Chittagong University, Bangladesh. Before sowing the seeds, different combinations of FSC and FWC were incorporated with nutrient-deficient natural forest soils. Seed germination and growth parameters of seedlings were recorded after two, three and four month of seed sowing. We observed that seed germination (%) and seedlings growth parameters varied significantly (p＜0.05) in the soil added with FSC and FWC in comparison to control. The highest germination was observed 88.89% for A. auriculiformis in combination of soil and FSC at 3:1 and 92.59% for S. mahagoni where soil combined with FWC at 4:1.
