Conteúdo: | Field experiments were conducted in 1990 and 1991 in Tucson, Arizona, to examine the effects of spatial arrangement and density on yield and biomass of an annual cotton/cowpea/maize intercrop. In lhe 1990 experirnent, treatments were combined inan unconfounded 4 x 4 factorial, which consisted offour spatial arrangements ofcotton, cowpea, and maize crossed with four cowpea/maize densities. in the 1991 experiment, treatments were combined in an unconfounded 5 x 2 + 1 factorial, which consisted ofílve densities ofcotton crossed with two densities of cowpea and maize, plus one additional treatment. The results ofthese cxperiments indicate that component-crop yield and biomass in an annual cotton/cowpeaimaize intercrop can be significantiy affected by lhe manipulation ofspatial arrangement and density as management factors. The most appropriate arrangements and densities in particular circumstances deperid on either lhe combined intercrop yield and biomass or Lhe yield and biomass of a specific component crop that is more highly valued.
