“…Limited screening and evaluation of cowpea landrace material have been done with regard to the rest of abiotic stresses. However, several cowpea genotypes and cultivars have been identified [ 209 , 210 , 215 , 216 ], and breeding lines with high temperature tolerance have been developed [ 49 , 217 ]. Landraces and other cultivated material were screened and appeared also to be promising in cultivation under calcareous and high alkaline soils [ 56 , 203 ].…”

Cowpea (Vigna unguiculata (L.) Walp.) is a legume with a constant rate of cultivation in Southern European countries. Consumer demand for cowpea worldwide is rising due to its nutritional content, while Europe is constantly attempting to reduce the deficit in the production of pulses and invest in new, healthy food market products. Although the climatic conditions that prevail in Europe are not so harsh in terms of heat and drought as in the tropical climates where cowpea is mainly cultivated, cowpea confronts with a plethora of abiotic and biotic stresses and yield-limiting factors in Southern European countries. In this paper, we summarize the main constraints for cowpea cultivation in Europe and the breeding methods that have been or can be used. A special mention is made of the availability plant genetic resources (PGRs) and their potential for breeding purposes, aiming to promote more sustainable cropping systems as climatic shifts become more frequent and fiercer, and environmental degradation expands worldwide.

“…Tão importante quanto à manutenção da atividade enzimática, o sincronismo do padrão de comportamento entre estas enzimas é fundamental para a defesa contra as EROs produzidas na célula vegetal (Barros et al, 2021), e refletirá diretamente na produtividade da planta. A primeira defesa contra as EROs é a SOD.…”

O cultivo do sorgo em ambientes salinos provoca alterações importantes nos processos fisiológicos que são diretamente relacionados com a produtividade das plantas. O estudo objetivou avaliar o efeito da irrigação, com água salina, na produtividade, na atividade enzimática e nas trocas gasosas em variedades de sorgo granífero. Três variedades de sorgo foram submetidas a frações de lixiviação com água salina com condutividade elétrica de 4,19 dS m-1, em esquema de parcelas subdivididas. Foram avaliadas as variáveis distribuição de sais no solo, taxa de fotossíntese e transpiração, temperatura foliar, condutância estomática, atividade das enzimas catalase, ascorbato peroxidase e superóxido dismutase, e produtividade de biomassa da parte aérea. A aplicação de frações de lixiviação com água salina proporciona melhor distribuição dos sais no perfil do solo. Plantas de sorgo submetidas a irrigação com água salina apresentam redução nas trocas gasosas e no estado hídrico das células. A defesa antioxidativa foi ativada em plantas de sorgo cultivadas em ambientes salinos para evitar o acúmulo de espécies reativas de oxigênio, sendo que o sincronismo entre as enzimas refletiu em uma resposta positiva na produtividade das variedades 1011-IPA e Ponta Negra, com aumentos de 126% e 54%, respectivamente, na produtividade de grãos com a aplicação de lâminas de lixiviação. A utilização de água salina com condutividade elétrica média de 4,19 dS m-1 é uma alternativa viável para o cultivo irrigado das variedades 1011-IPA e Ponta Negra em Argissolo Vermelho Amarelo.

“…The main value of cowpea is its high drought, heat, and salt resistance, which allows growing this crop for seeds, green manure, feed, and vegetables (Sysh & Bobos, 2011; Barros, 2021). However, an increase in temperature is associated with accelerated growth and the duration of the phenological phases of the crop.…”

“…Acceleration of development occurs due to the plant's response to stress, increased respiration (Schmidt et al, 2017). In this context, studying how cowpea plants respond to increased water scarcity and rising air temperatures, in the long run, can help growers change their management practices to maintain sustainable production (Barros, 2021).…”

The search and selection of cowpea varieties with optimal economic characteristics is a key factor in the development of cultivation technologies to increase yields. The purpose of the study was to determine the phenological and morphological characteristics of cowpea varieties and establish the relationship between economically valuable indicators and weather conditions. The leading approaches to studying this problem are field method – to assess the growth and development of cowpea varieties; statistical – to conduct variance and correlation analysis of the assessment of morphological features and economically valuable indicators of cowpea. Five cowpea varieties were studied: Groik (Israel), Kafedralna (Ukraine), Gasson (Vietnam), American improved (USA), and U-Cha-Kontou (China). It was found that the duration of phenological phases of cowpea varieties depended on weather conditions. Varieties of cowpea were characterised by early maturation periods for the sum of effective temperatures of 192.0-207.5°C and precipitation of 30.54-31.65 mm. Earlier maturation periods were the varieties American improved, Kafedralna, Gasson with the duration of the period from germination to the beginning of harvesting ripeness of the pod – 58-62 days and the duration of the period from germination to biological ripeness of seeds – 92-94 days. For the vegetable industry, bush varieties Kafedralna and U-Cha-Kontou with a plant height of 48.5-54.9 cm were promising, which formed tender long beans with a weak parchment layer (22.8-23.6 cm). Groik and Gasson varieties proved valuable for growing seedlings due to the small light-coloured seeds with a plant height of 61.8-100.5 cm and the formation of a large number of short beans on the plant (12.8-15.6 cm). A strong relationship between morphological features and economically valuable indicators of cowpea has been established. The average bean yield had a direct strong relationship with the total number of beans per plant (r=0.93) and a strong inverse relationship with the length of the bean (r=-0.88). As the length of the beans increased, the average yield of beans and the number of beans on the plant decreased, as evidenced by a strong inverse relationship between these indicators (r=-0.93). The materials of the paper are of practical value for increasing the species diversity of vegetable crops and improving the provision of valuable food products to the population
