About article:
Providing nutritional sources is crucial in order for plants to achieve optimum yield and quality of the produced yield; this becomes more important under stress conditions, to which drought belongs, representing one of the mainly increasing abiotic stresses. P fertilizer has a special role in enhancing the rooting system of plants, which might help in overcoming negative drought influence by enhancing water and nutrient uptake. Soybean is classified as a drought-sensitive legume, providing cheap source of both protein and oil. To evaluate the influence of P fertilizer on soybean yield and quality under moderate drought, an experiment was conducted in 2018 by applying three P fertilizer rates (0, 45 and 90 kg ha-1 of P2O5) to soybean (cv. Boglár) under two irrigation regimes; irrigated and moderate-drought-stressed regimes. Results showed that drought had negative effects on both yield and oil concentration; however, P application could alleviate drought's effects by enhancing both traits, moreover, it could enhance these traits when drought was waived off as well. P application had very small effect on protein concentration which was significantly higher under moderate drought conditions. Applying relatively-high rate of P could further increase oil concentration compared to lower P rate, however, it did not enhance yield or protein concentration. It was concluded that applying P fertilizer has positive effects on both yield and seed quality of soybean, especially under moderate drought, however, higher rate of P fertilizer had little influence on oil concentration only.
