Growth and yield of tomato cultivated on a substrate with organic fertilizers

Abstract

Project's main goal is to develop a so called biological cultivation method for tomatoes grown in a greenhouse. Research is done at Martens Vegetable Research Station in Finland. Different organic fertilizers are examined during 1995 in greenhouse experiments. The fertilizers are dried, granulated peat bedding from broiler farm, loose, composted peat bedding from broiler farm and biolite. Different fertilizer methods, e.g. timing, are examined. Amounts of nutrients are examined with leaf and substrate analyses. Yield and it's quality during period of growth are measured. Weight of leaves and sprouts which are taken away during period of growth, are measured.
