“…In the North and Northeast regions of Brazil, cowpea (Vigna unguiculata (L.) Walp.) constitutes one of the main components of the population diet, especially in the rural area, due to its high nutritional value (Silva et al, 2018). In these regions, it also stands out for its commercial value, representing one of the main sources of income for rural populations (Públio-Júnior et al, 2017).…”

Silicon and proline play important physiological, metabolic and functional roles in plants, especially under water deficit conditions. Their application can mitigate the adverse effects of stress in crops by increasing water use efficiency and antioxidant activity. The objective of this study was to evaluate silicon (Si) as attenuator of the effects of water deficit on cowpea cultivars, through physiological, biochemical and growth indicators. The experimental design was randomized blocks with four cultivars (BRS Guariba, BRS Itaim, BRS Aracê and BRS Rouxinol) and four irrigation treatments associated or not with Si application (W100 - 100% ETo; W50 - 50% ETo; W50+100Si and W50+200Si, with 100 and 200 mg L-1 silicon, respectively), in a 4 x 4 factorial scheme, with five replicates. Leaf water potential, proline concentration, antioxidant enzymes and growth indicators were evaluated in cowpea plants. Under water deficit conditions, all cultivars showed reductions in leaf water potentials, which compromised plant growth. However, Si applications of 200 mg L-1 in the cultivar BRS Guariba and 100 and 200 mg L-1 in the cultivar BRS Itaim minimized the effects of stress, by increasing leaf water potential and the activity of the enzyme ascorbate peroxidase, in both cultivars, besides increasing proline concentration in the former and reducing proline concentration in the latter, which ensured the maintenance of growth. Despite the no contribution to the increase in water potential, Si applications of 100 and 200 mg L-1 in BRS Rouxinol and BRS Aracê, respectively, reduced the deleterious effects of the stress on their growth by regulating the enzymatic metabolism and proline.

“…Nessa região, a produção na segunda safra de 2020 foi estimada em 295,9 mil toneladas, e os maiores estados produtores são Ceará, Piauí e Pernambuco (BRASIL, 2020). Contudo, apesar de ser cultivado em larga escala, os níveis de produtividade da cultura são inferiores ao seu potencial genético e produtivo (ROSOLEM, 1987;SILVA et al, 2018).…”

“…Cowpea (Vigna unguiculata), also known as black eyed pea in the USA, is traditionally known as Gorutubano bean in the semiarid region of the state of Minas Gerais, Brazil; it presents high yield potential when grown under ideal conditions of soil fertilization and water availability, and when is from a good genetic material (BRITO et al, 2012;MONTEIRO et al, 2012). Cowpea is typically grown by family farmers; it is an excellent source of proteins, essential amino acids, carbohydrates, vitamins, and minerals, mainly for low-income populations (SILVA et al, 2018a;CONAB, 2018).…”

Grain Yield and Microbiological Quality of Cowpea Plants Grown Under Residual Effect of Sewage Sludge Fertilization1

et al. 2020

Cowpea plants produce protein-rich grains and present high yield potential when grown under irrigation and organic fertilization, enabling to substitute part of the mineral fertilizer with sewage sludge, reducing costs and generating environmental benefits. Thus, a field study about residual effect of sewage sludge fertilization on cowpea was developed to evaluate this substitution. The experiment was conducted using a randomized block design with four replications, in a 2×5 factorial arrangement consisted of two fertilization types (residual effect of sewage sludge fertilization, and mineral fertilizers) and five cowpea cultivars (BRS-Pajeu, BRS-Xiquexique, BRS-Marataoa, BRS-Pujante, and BRS-Cauame). The residual fertilizations were from applications of sewage sludge and NPK mineral fertilizers for pineapple crops grown in the area before the cowpea crop. The experiment was conducted using 80,000 plants ha-1 and micro-sprinkler irrigation. Vegetative and yield components, grain yield, and microbiological quality were analyzed. BRS-Pujante had the highest cowpea grain yield (4,124 kg ha-1) and the highest means for vegetative and yield components. The soil with residual sewage sludge fertilization improved the cowpea root growth and grain yield (3,854 kg ha-1); the latter was 19% higher than that of treatments with mineral fertilization. These results were related to the great soil organic matter content provided by the sludge fertilization, which promotes nutrient mineralization, increasing grain yield. Fresh and dry grains of cowpea plants grown under residual effect of sewage sludge fertilization have similar microbiological quality to those of plants grown under mineral fertilization.
