| In this study, the effect of tillage and irrigation methods on energy use, energy indices, and greenhouse gas (GHG) emissions of grain corn production was evaluated. The research was conducted in the form of a split plot experimental design with three replicates in Fars province, Iran. Main plots were irrigation methods including surface irrigation (gated pipe), drip irrigation, and sprinkler irrigation. Tillage methods including no-till (NT), reduced tillage (RT), and conventional tillage (CT) were considered as sub plots in this research. Results showed that irrigation method had significant effect on energy use, output energy, energy indices, and GHG emissions of grain corn production, while tillage method had significant influence only on energy use,... |

| We examined samples of irrigation water and vegetables from kitchen gardens in Campinas, Brazil. The bacterial analysis condemned 22.3% of the vegetable samples, and the parasitological examination condemned 14.5%. The criteria established by the Brazilian legislation condemned 11.8% of the irrigation water samples. Parasites were significantly more frequent in vegetables in the rainy season, while excessive fecal coliforms were more frequent in the dry season. A proper monitoring of the irrigation water supply is important to avoid the contamination of vegetables. |

| ABSTRACT Inadequate and intensive management of soils can promote changes in their chemical attributes and impair the quality of surface and groundwater, especially in hillside areas. Therefore, the aim of this study was to identify possible changes in soil and water chemical composition of hillside areas cultivated with horticulture. For this, chemical attributes of three soil depths (0-10, 10-30, and 30-60 cm) were determined in three hillside positions (upper, middle, and lower thirds) of five hillside and adjacent forest areas, as well as water from reservoirs for agricultural use and human consumption. Compared with the forest area, horticultural areas present soil with lower organic matter content and CEC, but higher values of pH, base saturation,... |

| A limitação de recursos hídricos dificulta a produção de alimentos em regiões semiáridas, com distribuição irregular de precipitações pluviométricas. Dessa forma, a otimização desses recursos, captando água de chuva para uso doméstico, para a criação de animais e para a produção de alimentos se torna uma necessidade premente. Outra alternativa é utilizar a água armazenada em pequenas bacias de captação (lagoas, barreiros, pequenos açudes) que se formam durante o período chuvoso para cultivos de hortas e pomares. No caso de hortaliças, com espaçamentos pequenos entre plantas, deve-se molhar uma faixa contínua do solo, enquanto em fruteiras, com plantas de maior porte, recomenda-se molhar manchas de solo, aplicando-se uma quantidade menor de água por área,... |
