Abstract
The objective of this work was to formulate a peat-free substrate for organic production (OP) of potted parsley and coriander. Substrates were prepared with coconut coir fiber (F) and forestry wastes compost (C) in the following proportions (by volume): 1F:0C; 1/3F:2/3C; 2/3F:1/3C and 0F:1C. All the peat-free substrates were fertilized with an organic fertilizer, certified for OP. An OP certified commercial substrate (black Sphagnum peat, coir and organic fertilizer) was used as control. Parsley (Petroselinum crispum (Mill.) Fuss) and coriander (Coriandrum sativum L.) seeds were sown in 290 mL pots (diameter: 8.5 cm, height: 8.2 cm) and grown for 2 months. The compost substrate (0F:1C) had an electrical conductivity of 73 mS m-1 (water extract 1:5, v v-1), slightly higher than the adequate range, and the highest nutrient availability. Mixing compost with coir had a positive effect on the substrate properties, increasing nutrients availability as well as plants growth. The shoot mass of the plants (parsley and coriander) growing in the coir and compost mixes (2/3F:1/3C and 1/3F:2/3C) was significantly higher than the shoot mass of the plants growing in the peat-based control substrate. Furthermore, the cost of the peat-free substrates formulated in this study (0.045-0.063 € L-1) was significantly lower than the cost of the commercial substrates (0.109 € L-1). Compost and coir mixes proved to be a low cost efficient alternative to the commercial substrates for the organic production of potted parsley and coriander.
