To evaluate adequate and alternative techniques of production for vegetable crop nursery, the growth rate and quality traits of three vegetable - lettuce (Lactuca sativa L.), cabbage (Brassica oleracea L. var. capitata L.) and celery (Apium graveolens L.) - seedlings grown on a cocopeat medium added with different organic and natural fertilisers were evaluated and compared to seedlings grown on a peat medium and fertigated with the same fertilisers. Seedlings grown on cocopeat medium added with organic and natural fertilisers showed an increase of growth rate and higher quality traits compared to the ones grown on the traditional medium. On the contrary, the cocopeat added with organic fertiliser determined only a reduction of seedling quality. The seedlings grown on cocopeat and manure generally presented a decrease of growth rate, leaves number and area, but an increase of dry matter content. In all species, mineral fertilisers supplied by fertigation increased the quality traits of seedlings compared to organic fertilisers. The traits of seedlings grown on cocopeat medium added with organic and natural fertilisers and fertigated with organic fertilisers were similar to the ones of seedlings grown with the traditional method of growth, based on peat medium and mineral fertiliser for the fertigation. The cocopeat results a substrate suitable for the production of vegetable seedlings and moreover it allows a reduction of irrigation water because it slows down water release
