- Abstract
The paper presents the behavior of some wheat and barley varieties under 2018 conditions in Dobrogea area. In demonstrative plots carried out at S.C. SPORT AGRA SRL Amzacea, Constanța County is presented data about the main pathogens and yield results. Climatic conditions of autumn 2017 and spring 2018 favoured a major attack of pathogens. For barley a high attack of Rhyncosporium secalis with an attack rate (AR) of 6-30% and Pyrenophora teres in a lower attack rate of 3-20% in most varieties was reported in the April 17 observations. For wheat, Septoria tritici showed an AR between 18-23.5% and Pyrenophora tritici-repentis showed a low attack (AR= 4.5-17.5%). The pathogen Puccinia striiformis was present in low percentage (AR= 1-13.5%) in the April 17 observations. For crop protection against pathogens, 2 foliar treatments with fungicides were applied, Artea 330 EC in March and Priaxon EC in April respectively. After the last treatment with very good efficacy, there was noticed a decrease in the attack on most pathogens in May 8 observations. Fungal treatments have stopped the development of foliar and ear diseases. The beneficial effects were found in the good yields obtained. For barley crop, yields were 7800 kg/ha for Predator and 8500 kg/ha for Panonic variety. Wheat cultivation yields ranged from 7425 kg/ha for Miranda and 8025 kg/ha for Avenue to 8300 kg/ha for Kraljica variety. Quality indices ranged from 70.4 to 77.5% for hectolitre weight and 11.9-14.5% for protein. All these special yields have been obtained under non-irrigated conditions.
