Peat blocks: an innovative nursery medium vs. peat moss for enhancing chilli (Capsicum annuum L.) seedling growth under nursery conditions. Journal of Tropical Agriculture and Food Science (JTAFS), 53 (1). pp. 83-93. (2025)
Abstract
The selection of an appropriate nursery medium is crucial for optimising seedling growth and development in chilli
(Capsicum annuum L.) This study evaluated the influence of peat blocks and peat moss on seedling growth dynamics
under nursery conditions. A randomised complete block design (RCBD) with four replications was conducted at the
Horticulture Research Centre, MARDI, Serdang, Malaysia. Growth parameters, including plant height, stem diameter,
number of leaves, and leaf area, were assessed over 12 weeks after sowing (WAS). Results demonstrated that seedlings
grown in peat blocks exhibited significantly greater plant height (52.46 cm), stem diameter (0.65 cm), number of
leaves (29.00), and leaf area (524.54 cm²) compared to those in peat moss. Growth rate modelling using the sigmoidal
equation y = A/(1+be−cx) revealed that peat blocks-grown seedlings had a higher potential maximum value for all
parameters, indicating sustained and accelerated growth. Chlorophyll content and fluorescence measurements further
suggested better physiological responses in peat blocks-grown seedlings. These findings highlight the potential of peat blocks as an innovative and efficient alternative to traditional peat moss for enhancing Capsicum annuum L. seedling growth in nursery conditions.
