A high proportion of rice farming irrigation in the Central Region of Uruguay is done with water stored in dams. Maximizing water productivity is important as savings in water inputs would reduce pumping irrigation costs, increase rice area planted and allows to allocate water to irrigate other crops in a rotation. The aim of the experiment is to determine irrigation management practices and systematization field layout techniques that increase Water Productivity, contemplating the economic and environmental sustainability of rice farming systems in Uruguay. A split plot experimental design trial was conducted in the Experimental Unit located in Tacuarembó (32.11S, 55.10W). tThis paper includes results of the joint analysis of three seasons (2012-2013-2014). Treatments included two types of systematization with different vertical interval between levees (big plots): I. Conventional (VI-8 cm) and II. Alternative (VI-4 cm), 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 10 cm is maintained after flooding throughout all the crop cycle. In IP and I the water layer is re-established when the soil is still saturated. Rainfall was above the historical average throughout the crop cycle, 738 mm. Crop was direct drilled on 10th October with 160 kg seed/ha with cultivar INIA Olimar (Indica). Basal fertilization was 160 kg ha-1 of 19-19-19 (NPK) and Urea was 100 kg ha-1 fractionated at tillering and panicle initiation. Intermittent irrigation (IP and I) in low-infiltration rate soils (planosols) allowed for significant water savings input (35% or 2798 m3 water ha-1) without reducing rice grain yield (average = 7713 kg rice ha-1) but affecting negatively industrial quality compared to Continuous irrigation (C) (P<0.05). Water productivity considering only irrigated water were: 0.99(c), 1.31(b), 2.00(a) kg grain m3 water-1 for C, IP and I respectively (P< 0.05). There was no significant effect of systematization in any of the parameters evaluated (P< 0.05).

RESUMEN.- La agricultura extensiva en Uruguay es la actividad que utiliza la mayor parte de los herbicidas comercializados en el país, siendo la soja el principal cultivo agrícola. La evolución de malezas resistentes a herbicidas ha implicado, de modo general, un aumento del uso de estos productos. El objetivo del trabajo fue evaluar diferentes densidades de avena y centeno sembradas previo a la cosecha de soja en combinación con diferentes métodos de terminación (Químico "Q", rolado "R" o químico reducido + rolado "QR") sobre el enmalezamiento y rendimiento en el cultivo de soja siguiente. --------------- SUMMARY.- Extensive agriculture in Uruguay utilizes the majority of herbicides marketed in the country, with soybean being the main agricultural crop. The evolution of herbicide resistant weeds has generally led to an increase in the use of these products. The
objective of this study was to evaluate different densities of oats and rye sown prior to soybean harvest, combined with different termination methods (chemical "C" rolling "R", or reduced chemical + rolling "CR"), on weed infestation and yield in the following soybean crop. |
