. "The effects of fertilization of sugar beet (Beta vulgaris) plants with sulfur (S) in combination with nitrogen (N) on their growth and resistance to aphids (Aphis fabae) were studied. Plants were grown in constant conditions, on soil fertilized before sowing with different rates of N and S. Nitrogen in the form of ammonium nitrate and S in sodium sulfate were applied. Already single N and S stimulated plant growth but their effects were highly increased when applied simultaneously. Plants fertilized with single N had the highest infestation with aphids. Addition of S to N decreased stimulatory effect of N on infestation. The positive effect of S manifested namely when the amount of aphids per unit of plant matter were calculated. The ratio of applied N and S optimal for utilization of N for plant growth was optimal for plant resistance to aphids."@cs . . "RIV/00027006:_____/03:#0000030" . . "2002-01-01+01:00"^^ . "369-371" .
