Atributos de solo-planta e de produção de beterraba influenciados pela adubação com espécies da Caatinga

Abstract: RESUMO: Plantas da vegetação espontânea do bioma Caatinga têm sido usadas como adubo verde nos sistemas de produção de hortaliças na região Nordeste do Brasil com o intuito de aumentar a produtividade das oleráceas e melhorar a exploração do meio ambiente. O presente trabalho foi realizado com o objetivo de avaliar o efeito de três espécies espontâneas da Caatinga como adubo verde em diferentes quantidades de biomassa nos atributos químicos do solo-planta e na produtividade da beterraba. O delineamento experim… Show more

“…When the indices were observed for the differentiated partitions of each culture, the carrot contributed 2.40 and the cowpea-vegetable supplemented with 0.19 in the 2:2 arrangement. According to Bezerra Neto et al (2010), the species with the highest values of partial LER are considered more competitive for the growth limiting factors than the species with lower values of partial LERs.…”

“…An intercrop is considered efficient when the LER value is higher than 1.0, provided that the commercial pattern of the crops is reached (BEZERRA NETO et al, 2012). LER values higher than 1.0 were also obtained in intercropping systems between leafy-vegetables and/or leafy-vegetable and tubers, such as carrot and lettuce (ALMEIDA et al, 2015;BEZERRA NETO et al, 2007), arugula and coriander (MOREIRA, 2011), and carrot and arugula (LIMA et al, 2010). The complementarity nature of the crops involved in the intercropping system can be considered when the yield of the intercropping is higher than that obtained from an area planted with single crops, thus indicating a biological advantage in the process of intercropping (BEZERRA NETO et al, 2007).…”
