摘要
During the period 2019-2022a field experiment was carried out with durum wheat variety 'Progress', grown after three predecessors - peas, cotton and sunflower on the experimental field in Field Crops Institute - Chirpan under the conditions of organic farming. The beginning and duration of the following phenological phases were tracked: emergence, third leaf, tillering, spindle, outgrowth and full maturity. In organic cultivation of durum wheat after a pea predecessor, the phenological phases from budding to full maturity occur 6 days earlier than in the other two predecessors. It was found that during the study period the yield was greater after the predecessor pea. In the same variant, durum wheat plants are taller and have higher values of the reported indicators. The highest number of emerged 539 and recovered plants 492 was reported after predecessor cotton in the 2019/2020 crop year.
