Description
Summary:Compost improves the physical, chemical, and biological properties of soils. The objectives of the present study were to determine (1) the impact of compost-amended substrate on transplant growth and mineral nutrition and, after transplanting, the effects on plant mineral nutrition and fruit yield in bell pepper and (2) the effects of preplanting compost application to the field on plant mineral nutrition and fruit yield in bell pepper. Trials were conducted at the UGA Tifton Campus and at a grower's field. Bell pepper transplants were grown in peat-based substrate with compost at different concentrations. Transplants grown in compost-amended substrate had increased vegetative growth and increased leaf nitrogen. These transplants, however, when planted to the field, had marketable and total fruit yields similar to those of transplants grown in non-amended substrates. Field compost application (10 t·ha −1 ) before planting resulted in increased soil organic matter and increased concentrations of several leaf nutrients in mature plants although there was no impact on fruit yield and fruit nutrients. In conclusion, bell pepper transplants grown in compost-amended substrate had increased vegetative growth, indicating that compost may be a partial substitute for peat in transplant production.
