Abstract

Spraying humic acid on a growing plant cauliflower enhances chlorophyll and carotene levels in the leaves; its crucial role in protecting plants from salt stress, water stress, and heavy metals, and its many other advantages in saline soils. The research study was carried out in one of the agricultural fields in the Muqdadiyah area, Haruniyah area, 21km, using a randomized complete block design (RCBD) and a normal factorial experiment during the agricultural season 2019-2020. It was located 40 kilometers North-East of Diyala governorate, Baquba district. This study aimed to determine how adding anti-saline and spraying humic acid affects the yield parameters of Nahar cauliflower. The results demonstrated that the addition of anti-saline when treated with N2 was superior in the majority of the studied traits, including: (head weight, head diameter, percentage of dry matter in the heads, total yield, and total plant weight without the heads). Sequentially, the results demonstrated (4349 g, 26.39 mm, 15.79 %, 13.39 mcg ha-1, 1.971 kg plant-1) superiority over the control treatment. The majority of the analyzed parameters, including (head weight, head diameter, percentage of dry matter in heads, total yield, and total plant weight without heads) (3584 g, 26.52 mm, 16.80 percent, 15.15 tons H-1, 2.182 kg plant-1), were superior to the control treatment (3584 g, 26.52 mm, 16.80 percent, 15.15 tons H-1, 2.182 kg plant-1). The N2H2 treatment was found to be higher in most of the analyzed parameters, including (head weight, head diameter, percentage of dry matter in the heads, total yield, and total plant weight without the heads), which were (4684 g, 29.80 mm, 19.33 percent, 15.47 tons h-1, 3.224 kg plant-1) respectively compared to the control.
