Fig. 1. The land equivalent ratio (LER) on a biomass basis for the pea and barley components and their combined intercrops affected by (a) row configuration and (b) fertilizer N at Western Agricultural Research Center (WARC) during the period between 2000 and 2002. Different letters atop each bar within a crop component represent a significant difference based on Fisher's protected LSD (P < 0.05).

Fig. 2. The land equivalent ratio (LER) on a biomass basis for the pea and barley components and their combined intercrops affected by (a) row configuration and (b) fertilizer N at Central Agricultural Research Center (CARC) during the period between 2000 and 2002. Different letters atop each bar within a crop component represent a significant difference based on Fisher's protected LSD (P < 0.05).
