Environmental Resource Consumption in Wheat (Triticum aestivum) and Bean (Vicia faba) Intercropping: Comparison of Nutrient Uptake and Light Interception

Abstract

Wheat (Triticum aestivum) and bean (Vicia faba L.) sole crops and their mixture in three planting pattern (M1: alternate-row intercrop, M2: within-row intercrop, M3: mixed intercrop) were used to investigate the amount of resource consumption in terms of PAR interception and nutrient uptake. The experiment was carried out as randomized complete block design with four replications. The results showed that intercropping systems had a significant effect on environmental resources consumption, where intercropping systems had more nutrient uptake and light interception compared to sole crops, suggesting the complementarity effect of intercropping components in resources consumption. The ability of wheat and bean was different in intercropping systems in absorbing nutrients because of their differences in root morphology and cation exchange capacity.
