Abstract

Abstract A field experiment was conducted at the Abu Al-Fadl Forest Nursery Station affiliated with the Directorate of Agriculture of Al-Diwaniyah located (8 km north of the city center of Al-Diwaniyah Governorate) within longitude E 44.9 and latitude N 31.9, during the autumn season 2022-2023. In order to study the effect of biofertilization and the addition of organic extracts on the growth and yield of kale plants. Dwarf green seeds were used in cultivation. The experiment included two factors, the first: control biostimulants (adding water only), yeast extract (5 g.L -1 ), Folosyme (2 g. L -1 ) and Biohealth (2 g L -1 ). Factor 2: control organic extracts (water only), Urea (5 gm L-1), amino acids (5 ml L -1 ), humic (7 ml L -1 ) and seaweed (5 ml L -1 ). The averages of the treatments were compared using the least significant difference (L.S.D.). At a probability level of 0.05, the results can be summarized as follows:The results showed that there were significant differences when adding bio-fertilizer in the qualitative traits of kale plants, the treatment of adding yeast extract was excelled in the percentage of potassium in the leaves, the percentage of magnesium in the leaves, the content of vitamin C in the leaves, The addition of Follozyme was superior in the percentage of phosphorus in the leaves, while the treatment of the addition of Biohealth recorded excelled in the percentage of nitrogen, the content of calcium in the leaves, the content of iron in the leaves, and the content of zinc in the leaves. The results of the addition of organic extracts indicated that there were significant differences in the treatments, where the addition of urea excelled in the percentage of nitrogen in the leaves, the percentage of phosphorus in the leaves, the percentage of potassium in the leaves, While humic supplementation treatment excelled on the calcium content in the leaves, the content of magnesium in the leaves, the content of iron, the content of zinc in the leaves, and the content of vitamin C in the leaves. The interaction showed a significant effect, where the Biohealth + seaweed treatment achieved a significantly excelled in the calcium content in the leaves (3.670 mg.g), while the bi-interaction treatment, Folozyme + Humic, showed an excel in the percentage of nitrogen in the leaves (2.793%). The percentage of phosphorus in the leaves was (0.703%), and the bi-interaction of Biohealth + Humec treatment was excelled in the content of iron in the leaves (194.2 mg. kg -1 dry weight), the content of zinc in the leaves (97.22 mg. kg -1 dry weight), gave the overlap Yeast extract + amino acids has a higher potassium content (1.629%). The interaction gave yeast extract + humic excelled in the percentage of magnesium (1.870%) and the interaction gave yeast extract + urea excelled in the percentage of vitamin C (68.6 mg. 100g -1 fresh weight).
