The effect of seaweed, nitrogen, and iron on some medicinally active compounds in the seeds of the fenugreek plant (Trigonella foenum-graecum L.).

Abstract

A field experiment was carried out to study the effect of marine algae, nitrogen and iron on some medically active compounds of fenugreek plant seeds. In the field of experiments of Ibn Al-Bitar Vocational Preparatory School of the Directorate of Education in Holy Karbala, Department of Vocational Education during the winter season 2024-2023, The design of RCBD was used in the order of splinter plates, three repeaters and two factors. The first factor included six nitrogen concentrations, ground + iron addition sprayed on the plant (T1 0-0, T2 0-50 mg L^-1, T3 75 kg E^-1 - 0, T4 75 kg E^-1 - 50 mg L^-1, 150 T5 kg E^-1 - 0 and 150 T6 kg E^-1-50 mg L^-1) Factor II Three levels represent concentrations of Acadian marine algae extract (A0 spraying with distilled water only and A1 Spraying with marine algae at level 1 ml L^-1 and A2 level 2 ml l^-1 spraying). The results showed that the T4 combination treatment was significantly superior to 75 kg E^-1-50 mg L^-1 and gave the highest average protein concentration in seeds (18.33). The T6 combination treatment was significantly superior and gave the highest average total alkaloid content in seeds (3.52 mg 100 mg^-1) and total glycosides content in seeds(825.4 mg 100 g^-1) compared to the comparison treatment that gave the lowest averages.  A1 marine algae spraying at 1 mL^-1 level was significantly superior and gave the highest average protein concentration in seeds and total alkaloid and glycosides content in seeds (17.89%, 3.15 mg 100mg^-1 and 823.9 mg 100 g^-1 respectively compared to the comparison treatment that gave the lowest averages. A2 marine algae spraying at 2 ml^-1 significantly outperformed and gave the highest average carbohydrate content in seeds (84.1 mg g^-1) compared to the comparison treatment. As for the intervention, it did not show any significant effect on the studied qualities.
