Influence of various predecessors on the grain quality of durum wheat under organic farming conditions
Krasimira Tanevaorcid
Резюме: The experiment was conducted on a soil type Pellic Vertisols in the experimental field of the Institute of Field Crops - Chirpan in the period 2020 - 2023. The aim of the present study is to determine the influence of various predecessors on the grain quality of durum wheat grown under the conditions of organic farming in the region of Chirpan. Some indicators related to the quality of durum wheat grain were studied - protein content, wet gluten content, vitreousness, test weight, yellow pigments content. By the analysis of variance was found a proven influence of the predecessors, the year of cultivation and the interaction between the two factors on the variation of all the studied traits. The influence of the year of cultivation in the variation of the traits is significant: protein content of grain (79.99%) and wet gluten of grain (88.02%). The influence of various predecessors on the investigated parameters related to grain quality was established. The experiment was conducted with the Saya variety. Averaged over the study period under the specific agro-ecological conditions, the highest grain protein content was found for durum wheat after the predecessor pea (11.9% d.b.) and after the predecessor sunflower (11.7% d.b.) and after predecessor cotton, a lower value (11.3% d.b.) was found for this indicator. The wet gluten content of pea and sunflower predecessors (22.7% d.b.) was higher compared to the wet gluten content of cotton predecessor (21.1% d.b.). On average over the study period, the highest content of yellow pigments was found for durum wheat after predecessor cotton (19.26 b*), followed by that after sunflower (18.86 b*) and with the lowest content of yellow pigments was the variant after peas (18.51 b*).
