Manejos do solo associados a telas de sombreamento no cultivo da cebolinha no verão

Abstract: RESUMO Telas de sombreamento são amplamente utilizadas no sistema produtivo das hortaliças folhosas, todavia são desconhecidos os efeitos dessa tecnologia na cultura da cebolinha cultivada no verão. O objetivo desse trabalho foi avaliar a redução do preparo de solo, associado a telas de sombreamento, em cultivos sucessivos da cebolinha no verão. O experimento foi implantado no esquema de parcelas subdivididas com manejos do solo nas parcelas (1= grade aradora + grade niveladora + enxada rotativa encanteiradora… Show more

“…In general, all treatments showed similar responses, in terms of height there was a difference in the Aluminet colored mesh, number of leaves showed similar results, number of branches resulted significantly only in full sun, and leaf area showed similar results, this is due to the decrease of luminosity in the environment causing the etiolation of many species (Table 1). Hirata et al, (2017) discovered that plants cultivated beneath shading screens grew taller than plants grown in direct sun. Lone et al, (2009) observed lower plant height when grown in full sun, a behaviour due to excess luminosity, above the capacity that each plant species has for its development, resulting in stress known as photoinhibition of Scientia Naturalis, Rio Branco, v. 5, n. 2, p. 794-801, 2023 p. 798 photosynthesis, and thus decreasing plant biomass production capacity (BARBE; ANDERSON, 1992).…”

“…Similar tendencies have been described by Cavalcante et al (2011); when cultivating 'pitaya' in a protected environment, they verified a good performance in plant height. Likewise, Hirata et al (2017) evaluated the chives crop 49 days after transplanting and found higher plant height in a protected environment of 50% shading than in full sunlight.…”

“…Amarante et al (2009) evaluated the effect of screens on photosynthesis in apple trees and concluded that black shading screens similar to those used in this study reduced the solar radiation and, consequently, sunburn and the potential photosynthetic rate. There are few studies that relate the effect of shading screens and the etiolation of plants in fruit farming, but many studies on vegetables relate the use of shading screens with higher plant length (Costa et al 2011b, Hirata & Hirata 2015, Hirata et al 2017. Screens with 35 and 40 % of shading provided fruits with larger diameter, when compared to the screen with 80 % of shading, in the summer.…”
