Effects of Adding Anti-saline and Humic Acid Foliar Spraying on Yield Parameters of Cauliflower (Brassica oleracea var. Botrytis)

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