The objective of this work was to estimate the effects of genotype x environment interaction and the genetic potential of flood-irrigated rice cultivars, released between 1972 and 2017, for the state of Rio Grande do Sul, Brazil. The experiments were carried out in the field, in all agroclimatic regions of floodirrigated rice crop in the state, between the 2005/2006 and 2015/2016 crop years, totaling 60 environments (trials), with 1,961 experimental units. Twenty-five cultivars of irrigated rice were evaluated for the traits grain yield, plant height, days to flowering, and whole grain quality after milling. The values of adaptability and stability were estimated with the aid of mixed models. The rice cultivars BRS Pampa, BRS Pampeira, and BRSCIRAD 302 showed simultaneously high-genotypic grain yield, adaptability, stability, good agronomic traits, and good whole-grain yield after milling. 'BRSCIRAD 302' and 'BRS Pampa' show high-yield stability and can be recommended for all rice cultivation regions of Rio Grande do Sul. 'BRS Pampeira' is responsive to environmental improvements and is indicated for high-technology conditions. |

Integrated farming systems lead to high quality and quantity of food as well as better environmental quality, but these systems can provide some disadvantages, such as the possibility of occurrence of soil compaction, which can be detected through soil physical quality indicators. The aim of this work was to analyze the effect of long term Integrated Crop?Livestock (ICL) and Integrated Crop?Livestock?Forestry (ICLF) systems on soil physical quality. The experiment (randomized complete block design) was carried out from 2006 until november of 2012 at IAPAR research farm, Ponta Grossa, Paraná state, under soils with sandy loam texture. Soil depths of 0.00?0.05, 0.05?0.10, 0.10?0.20, and 0.20?0.30m were sampled in November 2012 to analyze soil physical quality. The soil relative density, structural stability index, S index, relative field capacity, plant-available water capacity, bulk density alert value, and least limiting water range were evaluated. Both integrated systems (ICL and ICLF) provided adequate soil physical quality; nevertheless, overall, the ICL system resulted in better quality. Our results showed that the forestry component in the ICLF system negatively affected the soil physical quality mainly at the 0.05?0.10 and 0.20?0.30m layers. |
