Intercropping of common bean and green corn in off-season crops. Performance of common bean cultivars

Abstract

Green corn demand, production of quality bean grain and better use of land and water resources can be used by small farmers through the intercropping of common bean and green corn in off-season crops. Field experiments were conducted in the Polo Regional Extremo Oeste- APTA, in Andradina -São Paulo State, in 2005 and 2006. The objective was to evaluate the performance of common bean cultivars grown in single crop and intercropped with green corn. The randomized blocks design with 9 treatments constituted by the combination of three common bean cultivars of different growth habits: IPR Colibri (Type I), IPR Juriti (Type II) and IAC Carioca (Type III), and two corn cultivars: CATIVERDE 02 (variety) and XB 7012 (hybrid), with four repetitions was used. The intercropping influenced the performance of all common bean cultivars. The green corn CATIVERDE 02 is more appropriate for intercropping with common bean. IAC Carioca, IPR Juriti and IPR Colibri cultivars present same behavior. IPR Colibri presented potential for intercropping.
