Resumo: The growth and yield of sunflower plants can be influenced by the plant population arrangement and the type of irrigation system adopted to meet the water requirements of the crop. This study examines the influence of different irrigation systems and spacings between planting rows on the development of sunflower cultivars for the sub-middle region of São Francisco Valley. The experiment was laid out in a randomized block design with a split-plot arrangement in which the plots consisted of three irrigation systems (drip, micro-sprinkler and sprinkler); sub-plots were represented by three spacings between planting rows (0.65, 0.55 and 0.45 m); and sub-sub-plots corresponded to two sunflower cultivars (Hélio 251 and Hélio 360). The following variables were analyzed: plant height; number of leaves; stem diameter; number of heads; head diameter; dry biomass of stems, leaves and heads; and achene yield. The different irrigation systems and row spacings markedly influenced the growth of the sunflower cultivars. The highest yield of cultivar Hélio 251 was obtained with the drip irrigation system and 0.55 m spacing. Cultivar Hélio 360 achieved the highest yields when irrigated by the micro-sprinkler system at 0.55 and 0.45 m spacing. In the sprinkler irrigation system, cultivar Hélio 360 obtained the highest yield at 0.45 m spacing.

O objetivo com este trabalho foi avaliar a influência de diferentes sistemas de irrigação e espaçamentos entre linhas de plantio no desenvolvimento de cultivares de girassol, para a região do Submédio do Vale do São Francisco. O delineamento experimental foi em blocos casualizados dispostos em parcelas subsubdivididas, sendo as parcelas três sistemas de irrigação (gotejamento, microaspersão e aspersão), as subparcelas três espaçamentos entre linhas de plantio (0,65; 0,55; e 0,45 m) e as subsubparcelas duas cultivares de girassol (Hélio 251 e Hélio 360). As variáveis analisadas foram: altura de plantas, número de folhas, diâmetro do caule, número de capítulos, diâmetro do capítulo, biomassa seca do caule, folhas e capítulos e produtividade de aquênios. Os diferentes sistemas de irrigação e de espaçamento entre linhas influenciaram o crescimento das cultivares de girassol de forma singular. A maior produtividade da cultivar Hélio 251 foi obtida quando submetida ao sistema de irrigação por gotejamento e ao espaçamento de 0,55 m. A cultivar Hélio 360 irrigado pelo sistema de microaspersão, alcançou as maiores produtividades, com os espaçamentos 0,55 m e 0,45 m. No sistema de irrigação por aspersão, a cultivar Hélio 360 expressou maior produtividade no espaçamento de 0,45 m.UEL2020-11-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa Empírica de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3858910.5433/1679-0359.2020v41n6Supl2p2899Semina: Ciências Agrárias; Vol. 41 No. 6Supl2 (2020); 2899-2910Semina: Ciências Agrárias; v. 41 n. 6Supl2 (2020); 2899-29101679-03591676-546Xreponame:Semina.
