“…In recent years, heavy metal toxicity has become one of the most serious threats to agricultural production, which may become even more urgent in the coming decades (Tonkha et al, 2020). In particular, the effect of heavy metal toxicity on cowpea is evident in almost all plant tissues and at all stages from seed germination to ageing, although these effects are strongest during seed germination and root system growth (Riyazuddin et al, 2021).…”

Determining the ecological plasticity and stability of varieties and hybrids of agricultural crops helps to comprehensively assess them, considering the productivity potential, qualitative technological indicators, and the level of resistance to stressful conditions. The purpose of this study was to investigate the development of the yield of beans of cowpea varieties with high ecological stability, plasticity, and adaptability. The leading methods of studying this problem are field-based – to determine the interaction of the research object with biotic and abiotic factors; statistical – to evaluate the results to determine the parameters of cowpea adaptability. Within the studied varieties, a direct and inverse correlation was established between the yield of cowpea and the sum of effective temperatures. For Groik (r = 0.36) and Kafedralna (Control) (R = 0.36), U-Cha-Kontou (r = -0.64) varieties, the correlation was average, while for Gasson (r = 0.96) and American improved (r = -0.98) varieties, it was strong. Based on the regression equations, an increase in the amount of precipitation by 1 mm can increase the yield of cowpeas by 3.4 kg/ha in the American improved variety and by 20.8 kg/ha – U-Cha-Kontou, and for the Gasson, Kafedralna (control), Groik varieties, there will be a decrease in yield by 6.4 kg/ha, 10.8 kg/ha, and 20.7 kg/ha, respectively. Varieties with high overall adaptive capacity, defined as the ability of genotypes to maximise the manifestation of traits under all environmental conditions, are valuable. High indicators of total adaptive capacity for plant yield were observed in the varieties Gasson (TAC = 5.16) and Groik (SAC = 2.16). The lowest value of this indicator was observed in the U-Cha-Kontou variety (TAC = -3.44). Varieties that produce high but unstable yields are not able to guarantee maximum yields in conditions of improper farming and difficult climatic conditions. The genotype breeding value is a complex indicator that determines the totality of productivity and stability of varieties. Studies have obtained such fluctuations in this indicator from 0.84 to 13.63. The best varieties in terms of genotype breeding value were Gasson (GBVi = 13.63) and Kafedralna (GBVi = 8.06). There is a relatively low yield stability and the ability to respond to improved growing conditions in the U-ChaKontou variety (GBVi = 0.84)

“…This crop also has fodder value and is promising, but until recently it has been insufficiently studied and too poorly distributed to increase the production of fodder and plant protein in EU countries, including Latvia. The agronomic importance of fenugreek for increasing soil fertility due to the ability of this plant to form nitrogen-fixing nodules is known (Bobos, 2015;Shelyuto, 2013;Plechishchik et al, 2010;Randhaw et al, 1996;Tonkha et al, 2020;Pavlista & Santra, 2016;Xalxo & Keshavkant, 2020). In this regard, the study of the economic features of Greek fenugreek and blue fenugreek as crops, recently introduced and little studied in Ukraine and Latvia, is of great scientific and practical interest.…”

The article presents the results of studies of two samples of fenugreek: blue (Trigonella coerulea (Desr.) Ser.) and hay (Trigonella foenum graecum L.) on the set of economic, biological and biochemical parameters. The researched samples of fenugreek have a wide range of variability of indicators depending on the terms of sowing and weather conditions. More rapid development was shown by fenugreek species on the summer sowing dates (III decade of June) with a vegetation period of 36–37 days. To obtain a high yield of green mass of fenugreek plants, the early spring (II–III decade of April) and late spring (I decade of May) sowing terms were more suitable. The obtained green mass yield was: 5.7–6.9 t∙ha–1 – blue fenugreek, and 7.3–9.3 t∙ha–1 – hay fenugreek, with the content of the dry matter being 12.4–28.4%, the sum of sugars 2.5–5.0% and vitamin C – 38.0–51.8 mg∙(100 g)−1. To obtain spices called “mushroom grass”, it is promising to use hay fenugreek with early spring (II–III decade of April) and late spring (I decade of May) terms of sowing, as a more developed vegetative mass is formed with the dry weight yield of plants 1.3–1.4 t∙ha–1. An increase in the amount of precipitation by 1 mm resulted in fluctuations of green mass yield from 15.0 to 77.3 kg∙ha–1 and dry mass yield from 0.693 to 25.9 kg∙ha–1.
