In all experiments phosphorus and potassium were applied in amounts necessary to bring up the soil content to 80 mg P and 200 mg K per 1 liter of soil, according to soil analysis after the modified Spurway method (Nowosielski et al 1976). In all experiments the cauliflower plants were spaced 50 cm between the rows and 50 cm within the rows.…”
