Sugar beet responce to sulfur and nitrogen and plant resistance to aphids

Popis výsledku v původním jazyce

The importance of sulfur (S) nutrition for utilization of nitrogen (N) by plant for their growth and the role of S in resistance of plants to aphids were studied in sugar beet (Beta vulgaris, L.) infested with black bean aphids (Aphis fabae). Plants weregrown at constant cultivation conditions on soil well supplied with nutrients. N and S were applied into the soil before sawing in the form of ammonium nitrate and sodium sulfate resp. in doses 0,1 and 0,2 g /kg dry soil in several combinations. 3 weeksold plants were treated with aphids. Both N and S stimulated plant growth, but their effects were significantly increased when applied simultaneously. Aphids feeding on plants fertilized only with nitrogen reproduced significantly more quickly. Sulfur supplement decreased the stimulatory effect of N on plant infestation. Sulfur at concentration corresponding to the best utilization of N for plant growth was the optimal for resistance of plants. Not only decrease of free amino acid conte
