Abstract

An experiment was conducted under dryland conditions at the University of Limpopo experimental farm, Syferkuil, in Capricorn district in 2009/10 and 2010/11 growing seasons to determine the effect of maize density and dry bean arrangement on performance of a maize/bean intercrop. The trial was a 2 x 3 factorial arrangement consisting of ten treatments: three maize densities (18500, 24700 and 37000 plants/ha), and two dry bean arrangements (single and double row arrangement). Sole treatments were added to enable comparison of the performance of sole crops and intercrops. 9c5c4cecc94702b0455ac94cc134323eMaize density of 18500 plant/ha achieved significantly (P<0.05) lower maize yield than 24700 and 37000 plants/ha in both seasons. Intercropping with double rows of dry bean resulted in higher maize yield in both seasons. The Combination of 37000 plants/ha with double arrangement achieved highest maize yield in both seasons. Maize density of 24700 plants/ha produced higher dry bean yield than 18500 and 37000 plants/ha. The double row bean arrangement resulted in higher dry bean grain yield in both seasons. The combination of 24700 plants/ha and double row arrangement attained the highest dry bean yield in both seasons. Intercropping achieved LER values greater that one. Maize density of 37000 plants/ha with double row of dry bean gave the highest LER value of 1.76 in 2009/10 season while in 2010/11 maize density of 18500 plants/ha with double row of dry bean arrangement achieved the highest LER value of 1.92. Maize/bean combination of 37000 plants/ha maize with double row arrangement of dry bean is recommended.
