“…The density of 28 plants m -2 resulted in the highest number of pods per plant and, consequently, a higher grain yield. Oliveira et al (2015), evaluating the interaction between water depths and plant densities in the cowpea growth and yield, using a conventional production system, observed a grain yield of 1,668.86 kg ha -1 , using 390.88 mm of water depth and density of 24.1 plants m -2 , for the BRS Itaim cultivar. Souza et al (2011) evaluated cowpea under a conventional production system and observed a grain yield of 1,376.9 kg ha -1 , with 449 mm of water depth, being 29 % higher than the one used in this study.…”

RESUMOin recent years, it has become an excellent income alternative for small growers and large farmers.However, despite being a genetically improved crop, concerning size and architecture for mechanized cultivation, its growing is still rudimentary in the main producing regions of Brazil. As a result of the low level of technology applied, the average grain yield is low, reaching the national average of 400-500 kg ha -1 (Alves et al. 2009). In the Piauí state, the average yield is 256 kg ha -1 , lower than the crop PALAVRAS-CHAVE: Vigna unguiculata (L.) Walp.; produtividade de grãos; irrigação.

“…It is observed that this combination is the result of the highest water depth with the lowest population density under study. Plant density (plants/m2) It is observed that the larger the plant population, the lower the production of pods per plant, a fact observed by several authors (BEZERRA et al, 2014;OLIVEIRA et al, 2015;MONTEIRO et al, 2017). This is justified by the high inter-and intra-plant competition at high population densities, a fact that is related to flower abortion and reduction in the number of lateral branches.…”

“…In this context, some studies have been conducted to define the density and/or spacing of cowpea plants that promotes maximum grain yield in irrigated or rainfed production system (SOUZA et al, 2011;BEZERRA et al, 2012;SANTOS, 2013;BEZERRA et al, 2014;LOCATELLI et al, 2014;OLIVEIRA et al, 2015;COSTA JÚNIOR et al, 2017;MONTEIRO et al, 2017;CARDOSO, MELO and RIBEIRO, 2018). However, the optimal planting density is variable due to the conditions of soil, climate and plant growth habit.…”

“…In addition to growth habit, the adopted water regime influences the adequate number of plants per area. Oliveira et al (2015), working with the cowpea cultivar BRS Itaim, of upright habit, found maximum grain yield of 1,668.86 kg ha -1 with the irrigation depth of 390.88 mm and plant density of 24.1 plants m -2 . Monteiro et al (2017), evaluating the effects of water regimes and plant densities on the production and yield components of the cowpea cultivar BRS Itaim in a conventional cultivation system, in the municipality of Teresina, PI, found the number of pods per square meter of 73.3, obtained with the combinations of irrigation depths and plant densities of 320 mm and 28 plants m -2 , respectively.…”

Cowpea is a legume of great socioeconomic importance for the North and Northeast regions of Brazil. However, studies to evaluate its production performance when cultivated under irrigated regime and under different plant densities are necessary. The objective of this work was to evaluate the effects of different water regimes and different plant densities on grain yield, production components and water use efficiency, and on the correlation between grain yield and production components of BRS Tumucumaque cowpea cultivar. The experiment was carried out at Embrapa Meio-Norte experimental area, in Teresina, Piauí State, Brazil, from June to September 2017, in an Argissolo Vermelho-Amarelo eutrófico (Ultisol). A randomized complete block design was used, in a split-plot scheme with four replicates, in which the water regimes occupied the plots (187.7; 233.5; 263.5 and 288.7 mm) and plant densities, the subplots (12; 16; 20 and 24 plants m-2). The number of pods per plant, number of pods per square meter, pod length, dry grain yield and water use efficiency were evaluated. The maximum dry grain yield reached was 1,694.46 kg ha-1, with application of 288.7 mm and density of 20.4 plants m-2. The production component number of pods per square meter was the most correlated with dry grain yield.

“…Em maiores populações, a competição intraespecífica é mais intensa no dossel o que potencializa a dominância apical, em detrimento do desenvolvimento das ramificações laterais (BEZERRA et al, 2010). Oliveira et al, (2015), trabalhando com a cultivar BRS Itaim, planta de porte ereto, em condições de sequeiro, observaram rendimento máximo de grãos 1668,86 kg ha -1 , na densidade de 241.000 plantas ha -1 .…”

Densidade de plantio do feijão-caupi na produtividade da cultura e na supressão das plantas daninhas. Planting density in cowpea productivity and weed suppression. ________________________________________________________________________________ ResumoObjetivou-se avaliar a influência da densidade de plantio do feijão-caupi sobre a produção e a supressão de plantas daninhas. Foram utilizados as cultivares BRS Aracê e BRS Guariba. Utilizou-se o esquema em parcela subdividida no delineamento de blocos casualizados. Os tratamentos da parcela foram as densidades e a subparcela os métodos de controle de plantas daninhas. Para a cultivar Aracê as populações de plantas que maximizaram a interceptação da irradiância foram de 166.667 e 181.739 plantas ha -1 , antes do florescimento e no florescimento pleno, respectivamente. Os maiores números de vagens por parcela e produtividade de grão foram encontrados nas populações de 128.000 e 121.000 plantas ha -1 na cv.BRS Aracê. Palavras-chave: Vigna unguiculata L, competição, população de plantas AbstractThe objective of this research was to evaluate the influence of the planting density of cowpea on the production and weed suppression. The cowpea cultivars used were BRS Arace and BRS Guariba. The experiment was a split plot scheme in a randomized complete block design. The plots treatments were the densities and the subplots were the weed control methods. The BRS Arace populations that maximized the interception of irradiance were 166,667 and 181,739 plants ha -1 , before flowering and during the full bloom, respectively. The highest numbers of pods per plot and grain productivity were found in the populations of 128,000 and 121,000 ha -1 plants in BRS Arace.
