| Description |
In the period 2012-2015, on the experimental field of the Institute, under the conditions of organic and conventional agriculture and in laboratory conditions, has been experimented in Sadovo with 24 varieties of winter wheat (Triticum aestivum L.). The purpose of the study is to assess the ability of varieties to extract nitrogen, its exports and unit production cost and its efficiency in organic and conventional farming.The results of this test give us the right to recommend varieties of common winter wheat as suitable for organic farming. Under the conditions of organic farming, nitrogen is most effectively accumulating the varieties Pobeda, Katia and Momchil, as the concentration of nitrogen in the grain is high and its concentration in the straw is low. Agronomically effective are the Enola and Geya-1 varieties. They have a low nitrogen consumption per 100 kg of basic and additional output and a high nitrogen harvest index (NHI).
