The research aimed to evaluate machine traffic effect on soil compaction and the least limiting water range related to soybean cultivar yields, during two years, in a Haplustox soil. The six treatments were related to tractor (11 Mg weight) passes by the same place: T0, no compaction; and T1*, 1; T1, 1; T2, 2; T4, 4 and T6, 6. In the treatment T1*, the compaction occurred when soil was dried, in 2003/2004, and with a 4 Mg tractor in 2004/2005. Soybean yield was evaluated in relation to soil compaction during two agricultural years in completely randomized design (compaction levels); however, in the second year, there was a factorial scheme (compaction levels, with and without irrigation), with four replicates represented by 9 m2 plots. In the first year, soybean [Glycine max (L.) Merr.] cultivar IAC Foscarim 31 was cultivated without irrigation; and in the second year, IAC Foscarim 31 and MG/BR 46 (Conquista) cultivars were cultivated with and without irrigation. Machine traffic causes compaction and reduces soybean yield for soil penetration resistance between 1.64 to 2.35 MPa, and bulk density between 1.50 to 1.53 Mg m-3. Soil bulk density from which soybean cultivar yields decrease is lower than the critical one reached at least limiting water range (LLWR =0). |

The aim of this study was to evaluate the effect of reducing water supply for watering of Santa In?es ewes on carcass characteristics, non-carcass components and the volume of digestive compartments. Thirty-two crossbred Santa In?es ewes, with an average body weight of 32.2 ± 7.4 kg, were distributed in a randomized block design with four treatments (different supply levels - 100% (ad libitum), 80%, 60% and 40% ad libitum water intake treatment) and eight repetitions. The animals were confined for 63 days until slaughter. The decrease in water availability promoted a linear decreasing effect for the internal carcass length (P = 0.032). A quadratic effect was found for the volume of the omasum (P = 0.018) and abomasum (P = 0.039), with maximum volumes of 0.305 and 1.636 liters, respectively, for 40% supply. The reticulum yield showed a quadratic effect (P = 0.044) with a maximum point in the supply of 100%, with 0.527%. The reduction in water supply promoted a quadratic effect for the weight (P = 0.016) and yield (P = 0.030) of the bladder, with maximum yields found in the supply of 60%, with 0.067 kg and 0.233%, respectively. There was a quadratic effect for weight (P = 0.042) and yield (P = 0.029) of the diaphragm with higher values found in the supply of 60%m with 0.272 kg and 0.927%, respectively. There was a quadratic effect for kidney yield (P = 0.022) with higher yield for 100% supply. Therefore, the reduction in water supply levels by up to 40% in relation to voluntary intake can be a strategy to be used in cases of water scarcity, as it does not cause negative effects on the Santa In?es ewe carcass.
