Coir-Based Growing Media with Municipal Compost and Biochar and Their Impacts on Growth and Some Quality Parameters in Lettuce Seedlings

The purpose of this study was to develop substrates with little or no peat by combining coir-based growing media municipal compost and/or acacia biochar, two locally produced renewable resources, and assess their effects on lettuce seedling emergence growth, as well content in photosynthetic pigments total phenols. Two experiments were carried out, the first six mixes using biochar blended perlite, pine bark, blonde adjust some physicochemical characteristics. coir: compost: bark: (73:12:5:10, v/v) biochar: (73:12:10:5, had characteristics closer within normal range substrates. presence 12% 10% mixtures adverse effect seed germination cumulative emergence, which ranged from 90 99%. growth those vigorous higher than other mixtures.
