1. Agronomic performance of white oats cultivated under fertigation with treated sewage effluent and definition of critical limits of Normalized Difference Vegetation Index
ABSTRACT One of the benefits of irrigation with wastewater in agriculture is the reduction in the use of mineral fertilizers and the increase in crop yield. For wastewater application, the use of remote sensing can help to define specific management areas. The aim of this study was to evaluate the yield and the growth of irrigated white oats (Avena sativa L.

2. SPATIAL VARIABILITY OF THE SATURATED HYDRAULIC CONDUCTIVITY OF SOIL IN COCOA FARMING IN RECÔNCAVO BAIANO
RESUMO O cultivo de cacau irrigado abriu espaço para a produção em solos de Tabuleiros Costeiros. Porém, nesta região, a camada coesa formada próxima da superfície, pode ser um fator limitante para sua produção. O conhecimento dos atributos físico-hídricos do solo possibilitará um manejo eficiente da irrigação em solos coesos. Com isso, objetiv

3. DIMSUB, a computer program for designing microirrigation subunits. Tool definition and case studies
ABSTRACT: DIMSUB is a computer program to complement a decision support tool (DST) to effectively study different hydraulic design alternatives in microirrigation systems. We developed environments in Visual Basic for applications for Microsoft Excel® that allow specific step-by-step functions to be created for the design of irrigation subunits. Different a

4. Genetic variability and breeding potential of Flintisa Composite of maize in two levels of technology
Abstract The purpose this study was to verify the breeding potential of Flintisa Composite for low (LT) and high (HT) technology of cultivation, and the best selection strategy to be adopted. For this reason half-sib progenies were evaluated in the two technological levels. In HT, it was used basic fertilization, two top dressing and supplementary irrigation

5. Distribution of rainfall probability in the Tapajos River Basin, Amazonia, Brazil
Resumo Estudos sobre a probabilidade de chuvas e suas variações espaço-temporais são importantes para o planejamento de recursos hídricos e otimização do calendário de atividades agrícolas. O presente estudo identifica a ocorrência de chuvas pela cadeia de Markov de primeira ordem (CM) e por dois estados da bacia hidrográfica do rio Tapajós (BHRT

6. Comparison of two rotary systems in bacteria/lps removal from endodontic infections: randomized clinical trial
Abstract: This clinical study compared the effectiveness of two rotary systems: HyFlex CM (Coltene-Whaledent, Altstetten, Switzerland) and ProTaper Next (Dentsply Sirona, Ballaigues, Switzerland) on the removal of cultivable bacteria and endotoxins from primarily infected root canals. This study was designed as a randomized single-blinded, 2-arm, clinical tr

7. Characterization and selection method of Venturi injectors for pressurized irrigation
ABSTRACT Venturi-type chemigation injectors are widely used due to their advantages: they do not require electric power and are cheap to operate. However, they also generate considerable energy losses which affect the pressure in the system. The correct characterization of these systems requires pressures to be correctly set at the inlet, injector and outlet

8. ENERGY EFFICIENCY OF A CENTER PIVOT IRRIGATION SYSTEM
ABSTRACT This study aimed to evaluate the energy efficiency of a center pivot irrigation system operating in a terrain of variable topography. Values of Pumping Energy Efficiency (PEE), Supply Energy Efficiency (SEE), Global Energy Efficiency (GEE) and Specific Energy (Es in kWh m-3) computed at 18 different angular positions of the lateral line were used as

9. Diallel analysis in cotton (Gossypium hirsutum L.) for water stress tolerance
Abstract Information about combining ability is important in determining breeding strategies. The objective of this study was to estimate the general (GCA) and specific (SCA) combining abilities among twenty cotton hybrid combinations submitted to water stress, based on agronomic traits. The trails were carried out in semiarid environment (Barbalha, CE), dur

11. Liquid Bovine Biofertilizer and Cultivation Effects on the Porosity of a Typic Haplocambids as a Function of Cultivation and Dose
ABSTRACT The soil porous space is where processes related to gases and soil solution occur, and provides an adequate guide for agricultural practices. This study aimed to evaluate the integrated effects of cultivation and the application of liquid bovine biofertilizer on the porous network of a Typic Haplocambids (Cambissolo Háplico Ta Eutrófico) cultivate

12. Sphingomonas from petroleum-contaminated soils in Shenfu, China and their PAHs degradation abilities
Abstract Members of the Sphingomonas genus are often isolated from petroleum-contaminated soils due to their unique abilities to degrade polycyclic aromatic hydrocarbons (PAHs), which are important for in situ bioremediation. In this study, a combined phenotypic and genotypic approach using streptomycin-containing medium and Sphingomonas -specific PCR was de
