- Abstract
This research was conducted to determine the effects of different doses of epibrassinolide (EBR) applications on the yield and some yield components of soybeans. Field experiments were carried out for two years (2022-2023) at the Isparta University of Applied Sciences (ISUBÜ), Faculty of Agriculture, Research and Application Farm, located in Isparta province, Turkey. In the study, seeds of the PG Victoria soybean variety were used as the material. For the hormone application from leaves, epibrassinolide (C28H48O6), a plant growth regulator from the Biosynth Carbosynth company, was used. The experiment was established with three replications according to a randomized complete block design. Before flowering, plants were subjected to foliar application of distilled water (control) and three doses of EBR (0.5, 1.0, and 1.5 μM EBR). In the study, 50% flowering time, plant height, first pod height, number of pods per plant, number of grains per plant, grain weight per plant, harvest index, hundred-grain weight, grain yield, and oil content characteristics of soybeans were examined. In soybeans treated with different doses of EBR, flowering period ranging from 56.0 to 59.7 days, plant height from 67.13 to 102.43 cm, first pod height from 10.23 to 14.03 cm, pods per plant from 16.80 to 80.30, grain number per plant from 42.73 to 193.53, grain weight per plant from 4.85 to 22.79 g, harvest index from %24.66 to %31.28, hundred grain weight from 11.00 to 13.00 g, grain yield from 270.16 to 566.67 kg da-1, and oil content from %20.56 to %21.49. When the results were examined, it was determined that there were wide variations in yield characteristics due to climatic differences appeared between experimental years. The results of the study indicated that the application of 0.5 μM EBR shortened the flowering period and increased plant height, pod number per plant, grain number per plant, grain weight per plant, and grain yield. However, applications above this dose were found to adversely affect yield components. The effect of EBR on the hundred-grain weight of soybeans varied over the years. The oil content, on the other hand, was found to increase at a dose of 0.1 μM EBR. [ABSTRACT FROM AUTHOR]
