The new regulation of organic cultivation starting 2022, and The Action plan for organic production in the EU, have as main aim the extinction of organically cultivated surfaces and to ensure trackability of products in a manner that will allow the significant decrease of the negative agricultural impact on environment and in human health. Due to the restrictions on organic foods, not many inputs as fertilizers or growth promoters are available for organic vegetable application. Products of natural origin are used in horticultural crops as a stimulator of the growth and development of plants. The present study was conducted in frame of a project developed in ADER program. In frame of the project research aims to identify, evaluate, tase, develop and validate methods for the analysis of nutrients and contaminants from inputs usable in organic farming. The project strategy includes application of two organic inputs in condition of certified organic field at SCDL Bacau on three important vegetable species: tomatoes, peppers, and cucumbers. The work presents the developed protocols in terms of application to highlight the potential of products to enhance quality and yield parameters, for two of three species, namely solanaceous. Assessment of total dry matter, total soluble solids, carotenes, lycopene, chlorophylls, and xanthophylls content and yield potential were accomplished. Application of these inputs may contribute to enhanced growth, yield, and resistance against specific pathogens, as well as the positive impact of content and activity of certain bioactive compounds.
