Rice farming systems in the North Region of Uruguay are mainly irrigated from water stored in dams. Increases in Water productivity would contribute to augment annually rice planted area, allows the allocation of water to irrigate other crops in a rotation and could contribute to reduce pumping irrigation costs. The aim of the experiments is to determine irrigation managem entpractices and field layout techniques that increase water productivity contemplating economic and environmental sustainability of rice farming systems in Uruguay. In this paper the results of the joint analysis of three seasons experiments conducted in the Experimental Unit Paso Farías, Artigas (30.30S, 57.06W) are presented (2012-2013-2014) .Treatments (split plot experimental design) included two types of systematization with different vertical interval between levees (big plots): I. Conventional (VI-8cm) and II. Alternative (VI-4cm), and three irrigation management practices (small plots): 1.Continuous (C), 2.Intermittent until panicle initiation (IP), and 3.Intermittent during all crop cycle (I). In C a water layer of 10cm is maintained after flooding
throughout all the crop cycle. In IP and I the water layer is allowed to decrease and is re-established when the soil is still saturated.
Crop was direct drilled on 21 st October (average) with 160 kg seed/ha with cultivar INIA Olimar (Indica). Basal fertilization was 100 kg ha -1 of 18-46-0 (NPK), and urea was 100 kg ha -1 fractionated at tillering and panicle initiation. Rainfall was on average 733 mm year -1 from October to March. Intermittent irrigation led to a significant savings in water inputs (38 % or 5567 m 3 water ha -1 ) and a significant increase in water productivity, affecting negatively industrial quality and grain yield (950 kg rice ha -1 less) (P< 0.05). Water productivity considering only irrigated water were: 0.57(c), 0.73(b) and 0.88(a) (kg grain m3 water -1 ) for C, IP and I respectively (P< 0.05). Regarding Systematization, there was no significant differences in any of the parameters evaluated between treatments (P <0.05).

Debido al gran aumento del uso del maíz para silo se plantea la necesidad de estudiar la adaptación de este cultivo a las condiciones de Uruguay. Se contó con los datos se de rendimiento en materia seca total de 133 cultivares evaluados en el período 1992/93 - 1998/99. La estimación de los componentes de varianza se realizó utilizando el método REML. Para el estudio del comportamiento de los cultivares en los ambientes de evaluación se utilizó un análisis de Regresión de Sitios. Para la caracterización de dichos ambientes se realizó un Análisis de Componentes Principales. Siendo que los componentes de varianza que afectan al genotipo son significativos, la elección de un cultivar no es una decisión menor. Dentro de los cultivares evaluados en el país existen tres grupos, uno de ellos que presenta adaptación general, otro que presenta adaptación específica, y finalmente otro pobremente adaptado. La adaptación específica se encuentra evidenciada sólo en los ambientes de alto rendimiento. Las variables ambientales vinculadas a la disponibilidad de agua explican el rendimiento de materia seca total y podrían explicar parte de la IGS. Esto sugiere que sería posible seleccionar cultivares con adaptación específica a situaciones de producción de alto potencial como sistemas bajo riego. |
