Desempenho de sistemas consorciados de cenoura e alface avaliados através de métodos uni e multivariados

Abstract: A análise de dados provenientes de experimentos de consorciação geralmente é mais complexa do que as advindas de experimentos em cultivo solteiro. Nesta situação, vários tipos de análises são recomendados, como análise univariada de variância do rendimento das culturas componentes separadamente; dos rendimentos combinados dos sistemas consorciados; da eficiência produtiva por modelos de análise de envoltória de dados (DEA) ou de métodos de análise multivariada dos rendimentos das culturas associadas. Neste tra… Show more

“…In each block, sole plots of the arugula, carrot and lettuce crops were planted to obtain the agro-economic indicators. PDs recommended for monocrops of these vegetables are 1,000,000 plants ha -1 for arugula (Freitas et al, 2009), 500,000 plants ha -1 for carrot (Oliveira et al, 2012) and 250,000 plants ha -1 for lettuce (Bezerra Neto et al, 2007b).…”

“…A significant difference between coriander cultivars was recorded only when they were associated with the -Esplanada‖ carrot cultivar, with the -Português‖ coriander cultivar presenting the highest score (2.05). On the other hand, a significant difference between carrot cultivars was observed when they were associated with the -Português‖ coriander, with the cultivar -Esplanada‖ standing out from -Brasília.‖ Between the cultivars of arugula, a significant difference was also observed, with -Cultivada‖ differing from -Folha Larga.‖ The multivariate analysis of variance of crop yield proved very informative and advantageous due to the higher discriminant capacity, besides the description of the relative superiority of the treatments (BEZERRA NETO et al, 2007).

“…Oliveira et al (2005), evaluating the combination of commercial cultivars of coriander adapted to the conditions of the Brazilian northeast with lettuce cultivars, found greater biological efficiencies in the combinations of Tainá and Asteca, and Babá de Verão and Português, with LERs of 1.62 and 3.21, respectively. The intercropping systems of the carrot -Alvorada‖ + the lettuce -Lucy Brown‖ or the carrot -Brasília‖ + the lettuce -Lucy Brown‖ were those indicated to the producer, with LERs of 1.26 and 1.21, respectively (BEZERRA NETO et al, 2007).…”

“…No caso específico de input constante, único e unitário, o modelo CCR é equivalente ao BCC (Lovell e Pastor, 1999). Bezerra Neto et al (2007aNeto et al ( , 2007b) avaliaram a eficiência produtiva de consórcios de cenoura e alface com o auxílio desse mesmo tipo de modelo.…”
