Optimum plant population for maize-bean intercropping system in the Brazilian semi-arid region

Abstract: Establishment of the ideal number of plant is a crucial point for obtaining maximum profits while cropping different species together. The main objective of the study was to investigate the effect of different plant populations of maize and beans, at two nitrogen levels, on the performance of the component crops. Two maize (20,000 and 40,000 plants ha -1 ) and three bean (30,000; 60,000 and 90,000 plants ha -1 ) populations were tested in a randomized complete block design with tree replicates.

“…Throughout the day, the attenuation of light is higher due to the inclination of the sun, which is one of many factors affecting the reception of light (STEWART et al, 2003), explaining the reduced productivity of certain cultures intercropped with maize, such as beans, even with maize rows spacing of 3.0 m, which is very common in northeastern Brazil (MORGADO;WILLEY, 2008).…”

“…This accords with observations by Li et al [9],. Morgado and Willey[10] and Dybzinski et al [11] that biodiversity could increase soil fertility and LER. In crop systems, there is great potential for the use of mixed cropping to enhance productivity, but this must be tested at a scale relevant to agricultural production[12]–[13].…”

“…Entre os manejos que visam à reposição de nutrientes há aplicação de estercos, quando disponíveis. As sementes de milho e feijão utilizadas são dos próprios agricultores (sementes crioulas), armazenadas e conservadas por eles cujas estratégias de conservação de sementes podem ser verificadas em Catão et al (2010) O plantio é realizado em covas e em consórcio, com média de cinco sementes de milho e três de feijão; o espaçamento entre linhas é variável (~ 1,0 x 0,5 m) em função do número de fileiras de feijão (2 a 3) entre as plantas de milho, Morgado & Willey (2008) relatam o consórcio de milho e feijão em região semiárida; não há uso de fertilizantes sintéticos.…”
