Abstract

Uslijed klimatskih promjena dolazi do pojava sve češćih intenzivnih suša koje znatno utječu na poljoprivrednu proizvodnju i sigurnost hrane. Soja kao vodeća proteinska i uljana kultura u svijetu osjetljiva je na stres suše te u sušnim uvjetima dolazi do znatnog pada prinosa zrna. U Republici Hrvatskoj se soja pretežno uzgaja u uvjetima suhog ratarenja, a reakcija dostupnih kultivara na stres suše nije poznata. Provedeno je ispitivanje šest genotipova soje ('DH 5160', 'Pedro', 'Maksimirka', 'Zagorka', 'Toma' i 'Sara') spram tolerantnosti na sušu. Pokus je postavljen u Maksimiru tijekom 2021. i 2022. godine, a u pokusu su provedena dva tretamana (navodnjavanje i induciranje suše). Praćeni su vremenski pokazatelji i tlak vlažnosti tla, a nakon žetve mjerena su agronomska svojstva u oba tretmana te je utvrđen visokosignifikantan utjecaj tretmana i godine na gotovo sva svojstva. Utvrđene su i značajne razlike među genotipovima u smanjenju vrijednosti ključnih komponenti prinosa.

Abstract (english)

As a result of climate change, intense droughts are occurring more frequently which significantly affect agricultural production and food security. Soybean, as the leading protein and oil crop in the world, is susceptible to the drought stress, and in dry conditions there is a significant drop in grain yield. In the Republic of Croatia, soybeans are predominantly grown under dry farming conditions, and the reaction of available cultivars to drought stress is unknown. Six soybean genotypes ('DH 5160', 'Pedro', 'Maksimirka', 'Zagorka', 'Toma' and 'Sara') were tested for drought tolerance. The experiment was set up in Maksimir during 2021 and 2022, and two treatments (irrigation and drought induction) were carried out in the experiment. Weather indicators and soil moisture pressure were monitored, and after harvest, agronomic traits were measured in both treatments, and a highly significant influence of treatment and year on almost all traits was determined. Significant differences among genotypes in the reduction of the values of the key yield components were also determined.
