20.500.12556/RUL-164459 Effects of pre- and post-transplantation humic acid biostimulant treatment and harvest date on yield quantity and quality parameters of sweet peppers (Capsicum annuum L.) The quality of sweet pepper seedlings is of paramount importance for optimal growth and yield in terms of both quality and quantity. This study examines the impact of two commercially available humic acid-based biostimulants applied pre- and post-transplantation of seedlings on the growth, yield, and fruit quality of a snack-type sweet pepper, Capsicum annuum L. ’Cuccino Orange’, at three key harvest dates. The results demonstrated that the application of the first biostimulant (Humic Blast) pre- and post-transplantation, significantly increased both yield (108.4 %) and fruit number per plant (123.9%) compared to control. Treated plants exhibited fruit with higher levels of glucose and fructose compared to untreated plants (10 to 18 %). However, other fruit parameters, such as length, width, and pericarp thickness, were not affected by the biostimulant treatments. While phenolic content varied among treatments, no consistent trend could be established, suggesting a complex interplay between humic acid application and secondary metabolite synthesis. The findings highlight the significance of selecting an optimal biostimulant application pattern. The application of biostimulants to seedlings has been demonstrated to enhance fruit growth and development, particularly when additional treatments are administered during the growing season. This has the additional benefit of improving yield. Overall, this research provides valuable insights into the optimal use of humic acid-based biostimulants in pepper production and offers practical guidance for growers seeking to maximize crop productivity. biostimulants growth rate metabolism humic acids harvest time bazilika biostimulanti Capsicum annuum paprika rast metabolizem true false true Angleški jezik Slovenski jezik Članek v reviji 2024-10-25 13:31:21 2024-10-25 13:31:27 2024-11-27 15:07:41 0000-00-00 00:00:00 2024 0 0 10 str. art. 113747 Vol. 338 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 635 0304-4238 10.1016/j.scienta.2024.113747 212999427 1-s2.0-S0304423824009002-main.pdf 1-s2.0-S0304423824009002-main.pdf 1 6ED1F08E7B25E826075CFB0EAFAD5F21 15dca19e3ddcff23b9568308e09f4e8f591bd9aaf4c88bc62c426bdd4360a1c1 ed036de5-92c4-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=194878 https://www.sciencedirect.com/science/article/pii/S0304423824009002 1 5fd412b5-92c4-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=194877 Biotehniška fakulteta 0 0 0
