Nitrogen fertilization in wheat: influence on yield and water use efficiency. Semi-arid Pampas Region.
During wheat season 1985/6 the fertilization influence was studied at sowing (100 kg N/ha applied in early growing = CT) and a combined fertilization (30 kg N/ha in early growing + 70 kg/ha - in hearing) on both. a modern wheat cultivar (Buck Pucará) and a traditional one (Buck Napostá). In both cultivars. the fertilization treatments increased yields significantly (greater number of heads per unit area grain per ear and 1000 seeds weight). The traditional cultivar did not show significant differences in water consumption under fertilization treatments. However, fertilization increased the efficiency of water consumption (tester = 1.77; CT = 4.25 and CT+E = 3.85 kg/ha mm).

En la campaña 1985/86 se estudi6 la influencia de la fertilización a siembra (100 kg/ha de N aplicado en crecimiento temprano = CT) y fertilizaci6n combinada (30 kg/ha en crecimiento temprano + 70 kg/ha en espigazón = CT+E) en un cultivar moderno de trigo (Buck Pucará y otro tradicional (Buck Napostá). En ambos cultivares los tratamientos de fertilización incrementaron significativamente la producción (mayor número de espigas logradas por unidad de superficie. de granos por espiga y peso de 1000 granos). No se registraron diferencias sustanciales en el consumo de agua para los tratamientos de fertilización evaluados en el cultivar tradicional. Sin embargo la aplicación de N incrementó la eficiencia en el uso del agua (testigo = 1.77; CT = 4.25 Y CT+E = 3.85 kg/ha.mm).
