摘要:The effects of phosphorus (P) and iron (Fe) supply on nitrogen concentration in vegetative organs of soybean plantsgrown in well-watered and stressed conditions have been studied. Experimental results have been established that adequateP and Fe nutrition increased signifi cantly the concentration of nitrogen in leaves and nodules indifferent of moisturelevel of soil. Fe supplemental application induced the production of nitrogen compounds in well-watered as well as inplants subjected to water stress conditions. The combined supply of P and Fe increased plant productivity in both normaland water stress conditions. Hence, the adequate mineral nutrition of soybean contributes to maintain physiological activityand to reduce the negative impact of drought on the plant production
