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 techniques that increase Water Productivity. This paper includes results of the joint analysis of three seasons (2012-2013-2014). A split plot experimental design trial was conducted in the Experimental Unit located in Tacuarembó (32.11S, 55.10W).
Treatments 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 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) without reducing rice grain yield (average = 7713 kg rice/ha) 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 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).

ABSTRACT.- Potential trade-off among weaning (WWT) and yearling weights (YWT), greasy fleece weight (GWT) genetic resistance to gastrointestinal nematodes assessed by faecal worm egg account (FEC), residual feed intake (RFI) and methane (CH4) and carbon dioxide (CO2) emissions were investigated in 217 Corriedale female lambs. Improving RFI was strongly associated with lower dry matter intake (DMI) and independent of metabolic body weight (MWT) and average daily gain (ADG). Person correlation coefficients were also no significant (P>0.05) with WWT, YWT, GFW and FEC expected progeny differences (EPD). FEC EPD was not correlated with any of the traits investigated here. Both CH4 and CO2 were not associated with RFI, although the moderate correlations with DMI. Higher EPD for WWT, YWT and GFW were correlated with higher DMI, CO2 and CH4. Optimising higher productivity and environmental sustainability requires further research for a more comprehensive understanding of these associations. |
