Winter wheat genotype ability to recover nitrogen supply by precedent crops under combined nitrogen and water scenarios

Legumes offer the opportunity to reduce nitrogen (N) fertilizer requirements of crop rotation but capacity subsequent recover N provided by legume determines saving. Therefore, breeding for genotypes capable take up under different limiting conditions is essential understanding performance and optimizing fertilization. The objective this work was test ability four wheat ( Triticum aestivum L.) with drought-tolerance (Cellule, Apache, Allez-y, Nogal) from precedent water scenarios. Two field experiments pea–wheat barley–wheat rotations, two irrigations levels, three treatments were conducted in central Spain over 3 years. biomass, uptake, nutrition index (NNI) determined at flowering, grain yield (GY), concentration (GNC), output harvest. crops enabled a reduction fertilizer, its effect depended on genotype climate conditions. drought-tolerant (Apache Cellule) had highest NNI, GY, low inputs, whereas Allez-y Nogal obtained better non-limiting study confirms differences between genotypes, root system, uptake levels highlights potential NNI assess status. • Barley-wheat pea-wheat rotations various × levels. Study bread drought-tolerance. Drought-tolerant present higher N. Nitrogen identified capability. Identification translocation should be improved.
