The research was carried out from 2013 to 2019 in the Institute of Horticulture (LatHort). The aim: to evaluate the influence of agroecological factors on the rarely-grown vegetables yield and quality on three morphological different species: stinging nettle (Urtica dioica L.), globe artichoke (Cynara cardunculus L. var. scolymus) and vegetable soybean (Glycine max L.). The tasks of the research: • to evaluate the growth and development of stinging nettle, globe artichoke and vegetable soybean under various agrotechnical factors and meteorological conditions; • to evaluate the influence of various agrotechnical factors and meteorological conditions on the yield of selected vegetables; • to determine and evaluate the nutritional value changes under various agrotechnical factors and meteorological conditions. Work novelty: for the first time in Latvia the investigations on the influence of agroecogical factors on stinging nettle, globe artichoke and vegetable soybean are performed. All these vegetables have high potential for the healthy human diet. Work hypothesis: ensuring suitable agrotechnical factors and reducing effect of meteorological conditions can increase studied vegetables yield and the content of biologically active compounds. Scientific actuality of work: obtained results are important and useful for commercial vegetable producers, the research gives insight in the yield formation and crop quality changes under various agrotechnical factors and meteorological conditions. The structure of the Thesis: introduction, literature review, materials and methods of the research, results and discussion, conclusions, references and appendix. Introduction. Topicality of the work is justiefied, research goal and tasks are formulated, research novelty and hypothesis are estimated.
