Treść
A three year experiment was intended to evaluate the effect of intercropping and soil type on specific root length (SRL). Crop mixtures included: (i) linseed with pea; (ii) linseed with vetch. Experiment was conducted on different soil type: Chernozem (A) and Cambisol (B). Roots length demonstrated high degree of plasticity in development in response to local heterogeneity of the soil profile - determined by water availability, and plant diversity. The studies found significant differences of SRL between species. Significantly greater SRL value was noticed for species in pure sowing, while lower values were observed for plants in mixture. Higher SRL was noticed for plants in Cambisol soil, which was characterized by higher soil humidity, regardless of drought periods occurring. Better soil conditions, described by higher amount of precipitation, significantly influenced the SRL of the species tested. The value of specific leaf area index significantly increased with increasing amount of precipitation (TP) in Olszanica (Cambisol). Higher value of SRL to TP association was noticed for legumes (pea or vetch) in mixture with linseed. Significant positive relations exist between SRL and TP of legumes cultivated in mixture with linseed; SRL increased with increasing amount of precipitation (TP). The highest correlations of SRL and TP were observed for pea in mixture with linseed (for pea r=0.982: P≤0.05).
