Abstract

CARVALHO, JOSÉ EDUARDO B. DE et al. Legume plants in the integrated weeds control to improve orange 'Pera' yield. Rev. Bras. Frutic. [online]. 2002, vol.24, n.1, pp.82-85. ISSN 0100-2945.  http://dx.doi.org/10.1590/S0100-29452002000100018.

Aimed to evaluate the productivity of sweet orange "Pera" grown considering two different ecosystems and under two soil management systems to control weeds. This work was carried out at the cities of Rio Real and Conceição de Almeida, Bahia State, during the period from 1994 to 1999. The soil management used by the farmer comprised three hoeings within planting lines and three harrowings between the planting lines. The new soil management proposed used a green cover of pig beans (Canavalia ensiformes, L.) between the planting lines along with subsoiling, associated with a chemical control of the weeds by Gliphosate, on the planting lines, twice a year. The soil management proposed yielded better results than the farmer soil management at both ecosystems for fruit weight of fruit, number, and plant productivity. At Conceição do Almeida and Rio Real the proposed soil management was 56,8% and 64,9%, respectively, superior than the farmer system.

Keywords : citrus; soil management; pig beans; weeds.
