afs-71806	Erviö, Leila-Riitta	Growth of weeds in cereal populations	1972	10	.pdf	application/pdf	3379	218	68	Figures 3 and 4 illustrate the sharp decline in weed yield caused by cereal seed rate increments from 25 to 200 and 400 kg/ha. This is in accordance with earlier studies of competition between weeds and cultivated plants, which likewise have demonstrated that dense stands of cultivated crops are effective in reducing weed yields (Winifred and Brenchley 1917, Granström 1962, Nelson and Nylund 1962, Weber and Staniforth 1957, Wiese et al. 1964).	cache/afs-71806.pdf	txt/afs-71806.txt
