Abstract
This study aimed to evaluate the effects of applying the organic soil salinity corrector Neutra-Sol 335 and boron fertilization at different levels on vegetative growth characteristics and yield performance of broccoli (Brassica oleracea var. italica). The experiment was conducted during the winter growing season of 2023–2024 in the vegetable field of the Department of Horticulture and Landscape Engineering, College of Agriculture, Al-Qasim Green University. The study was arranged in a randomized complete block design (RCBD) with a factorial layout and three replications. The treatments included three levels of salinity corrector (0, 10, and 20 mL L-¹) and three levels of boron (0, 5, and 10 mL L-¹), which were applied through the drip irrigation system. The results showed significant effects of salinity corrector and boron application, as well as their interaction, on most of the evaluated growth and yield parameters. Application of the salinity corrector at 20 mL L-¹ significantly increased leaf number, chlorophyll content, and dry matter percentage compared with the control treatment. Boron fertilization, particularly at 10 mL L-¹, improved photosynthetic performance and increased head weight and head diameter. The combined treatment of 20 mL L-¹ salinity corrector and 10 mL L-¹ boron produced the highest values for most measured traits, including maximum head weight (497.7 g) and total yield (9.707 t ha-¹), significantly exceeding most other treatment combinations. These findings highlight the role of salinity corrector and boron fertilization in improving soil physicochemical properties, enhancing nutrient availability, and ultimately promoting plant growth and yield.
