- Abstract
Growth, development and nutrient accumulation in Chenopodium album and Senecio vulgaris grown in pure and mixed stands were investigated through several experiments conducted under glasshouse conditions. Results showed that the two weeds were different in their growth, development and tissue concentration and accumulation of mineral elements. The mean concentrations of nitrogen, phosphorus, potassium, calcium and magnesium in shoots of C album were higher than those of S. vulgaris, while root concentrations of nitrogen, potassium and magnesium were lower for C. album. Marked differences between the two weed species in their responses to different potassium levels were found. C. album had a high specific requirement for potassium while the reverse was true for S. vulgaris. The competitive ability and accumulation of nutrients by C. album appeared to be greatly dependent on the availability of high potassium levels in the media.
