Özet:

 


Applying mineral fertilizers is one way
of re-fertilizing soils being exploited in agricultural production. However, fertilization
quantity should be controlled and pre-evaluated, as excessive amounts have
negative influence on both the plants and the soil. Drought stress has negative
effects on both the quantity (yield) and the quality (seed content) of crops,
especially drought-sensitive crops such as soybean; however, fertilization, if
adequately applied, can partially ameliorate those negative effects. An
experiment was conducted in Debrecen, Hungary in 2017 and 2018 to study the effects
of nitrogen fertilization application under drought stress on the yield and the
seed protein and oil concentrations of two soybean cultivars. Three N
fertilization rates; 0, 35 and 105 kg ha-1 were applied under two
irrigation regimes; Irrigated (control) and drought stressed (non-irrigated) regimes.
Results showed that yield trait responded differently to fertilization and
irrigation in the two cultivars. Protein concentration was enhanced by
irrigation and by the high rate of N-fertilizer, whereas oil concentration
decreased by irrigation and by high-rate fertilization under drought
conditions, whereas increased by high-rate fertilization under irrigated
regime. It was concluded that high rate of N-fertilizer can decrease the yield
of both cultivars under no-drought conditions.
