Effect of nitrogen fertilization and the environment on the yield and baking quality of two wheat varieties in the semi-arid Pampas region
Wheat is a cereal of great importance in human nutrition, so the quality assessment is proportional to production. You should not only think about the quantity of grains that are going to be produced but also about their ability to achieve quality flour with efficient use of resources. The objective of this work was to characterize environmental and management factors that determine the quality and productivity of wheat cultivation in the province of La Pampa. Two varieties of wheat belonging to two different quality groups (GC) (GC 1 and 2) were evaluated, in the coarse plain and in the medanous plain. The treatments were an unfertilized control, fertilization at sowing with two doses of nitrogen (N) (40 and 80 kg.ha-1), postponed (40 and 80 kg N.ha-1) and divided into sowing and tillering. At each site, an initial characterization of edapho-climatic variables was carried out. In tillering, heading and harvest maturity, edaphic humidity, nitrates in soil and total dry matter were determined. At maturity, the yield components and baking quality attributes were determined. No variety-site-management interaction was found. The 40S+40M and 80S treatments achieved the highest growth rate, therefore, more biomass and yield. Protein content had site-management interaction. Sites differentiated by their nutrient supply and edaphic quality have different N requirements to achieve 11% protein with the highest yield, and optimizing efficiency in the use of N. The higher N content increased the gluten content and W. The varieties did not present differences between them and their behavior was more influenced by their site than by the GC. The site and fertilization had a notable influence on productivity and the expression of quality. Director: Funaro, Daniel Oscar Co-director: Quiroga, Alberto Raúl

Director: Funaro, Daniel Oscar Co-director: Quiroga, Alberto Raúl El trigo es un cereal de gran importancia en la alimentación humana por lo que la valoración en la calidad es proporcional a la producción. No solo se debe pensar en la cantidad de granos que se van a producir sino también en su aptitud para lograr harina de calidad y con un uso eficiente de los recursos. El objetivo de este trabajo fue caracterizar factores del ambiente y del manejo que determinan la calidad y productividad del cultivo de trigo en la provincia de La Pampa. Se evaluaron dos variedades de trigo pertenecientes a dos grupos de calidad (GC) diferente (GC 1 y 2), en la planicie con tosca y en la planicie medanosa. Los tratamientos fueron un testigo sin fertilizar, fertilización a la siembra con dos dosis de nitrógeno (N) (40 y 80 kg.ha-1), postergada (40 y 80 kg N .ha-1) y fraccionada en siembra y macollaje. En cada sitio se realizaron una caracterización inicial de variables edafo-climáticas. En macollaje, espigazón y madurez de cosecha se determinaron humedad edáfica, nitratos en suelo y materia seca total. En madurez, se determinaron los componentes del rendimiento y atributos de calidad panadera. No se encontró interacción variedad-sitio-manejo. Los tratamientos 40S+40M y 80S lograron la mayor tasa de crecimiento, por lo tanto, más biomasa y rendimiento. El contenido de proteína tuvo interacción sitio-manejo. Los sitios diferenciados por su aporte de nutrientes y su calidad edáfica tienen requerimientos de N distintos para lograr un 11 % de proteína con el mayor rendimiento, y optimizando la eficiencia en el uso del N. El mayor contenido de N incrementó el contenido de gluten y W. Las variedades no presentaron diferencias entre ellas y su comportamiento estuvo más influenciado por su sitio que por el GC. El sitio y la fertilización influyeron notablemente en la productividad y en la expresión de la calidad.
