The effect of different doses of magnesium treatments on the fenugreek (Trigonella foenum-graecum L.) yield

Abstract

Fenugreek (Trigonella foenum-graecum L.) is an annual plant belonging to the legumes (Fabaceae) family. The plant is a Mediterranean one, native to the Mediterranean coast. It is a multi-use plant that is used as a herb, spice, and fodder plant. Fenugreek has high protein content and is well suited for feeding domestic and wild animals. Our open-field experiment was set up at the beginning of April 2018 in John von Neumann University, Faculty of Horticulture and Rural Development (Kecskemét). The treatments were: treatment 1 = 150 kg/ha, treatment 2 = 300 kg/ha, treatment 3 = 450 kg/ha complex fertilizer. The treatments were carried out in plots of 50-50 m². In the experiment, different nutrient supply treatments were set up to achieve the highest fresh biomass weight. The fertilizer used in the research was Novatec premium (15 N - 3 P₂O₅ - 20 K₂O - 2 MgO). When measuring fresh weight of fenugreek, the highest value was measured after 300 kg/ha treatment (14.45 kg). The values of treatment 1 (7.8 kg) and the treatment 3 (8.5 kg) were almost the same. The highest dose of treatment (450 kg/ha) resulted a decrease in the yield of T. foenum-graecum in our experiment.
