Pulse drip application is a management option to prevent clogging and improve water-use efficiency. The measurement of distribution uniformity opportune for pulse irrigation projects ensure efficiency since the shorter time, more negative influence transition periods have. objective present work was monitor quality system with different emitter models times. experiment conducted under laboratory bench conditions, 25 tests were performed each (2, 3, 6 12 minutes) model (non-compensated...
The purpose of this study was to evaluate the uniformity distribution coefficient (UDC) and variation (CV) a familiar set irrigation, classifying it ASAE standard. irrigation fertigation are determined by two methods KELLER & KARMELI DENÍCULI . experiments were subjected varying pressures: 12, 14, 16 18 kPa, in completely randomized design twenty samples composed flows with three replications. Urea, potassium chloride (KCl) ammonium phosphate (MAP) elements used for fertigation. system...
In arid and semi-arid regions, irrigation is extremely important for agricultural production. However, water salinity a major threat both to the soil-plant combination longevity of materials that make up system. Drip with direct intermittent photovoltaic pumping can play key role in optimizing saline water. This article compares two pump models understand which has greatest capacity reduce risks irrigated agriculture. The evaluation ideal was conducted using electrical hydraulic parameters...
Irrigation is crucial for agricultural production in dry regions. However, water salinity a risk the soil–plant combination and longevity of materials that make up irrigation system. Drip using direct intermittent photovoltaic pumping can be key optimizing with saline water. This article compares two pump models to understand which has greatest capacity reduce risks irrigated agriculture, aiming system more sustainable through efficient irrigation, without need highly expensive corrective...
Abstract. Boas M, Urim J, Iamba KS. 2025. Impact of planting rotations and tree age on insect pests weeds in balsa plantations East New Britain, Papua Guinea. Biodiversitas 26: 1618-1629. Balsa (Ochroma pyramidale) is an income-generating crop Britain Province (ENB) Guinea, repetitive (rotations) the same piece land can result pest weed incursions. We sampled insects from three rotations: rotation 1, 2, 3, across two groups: 1-9 months 10-18 old trees within each rotation. found that did not...
AbstractThe effects of cycle time (CT) (8, 12 and 16 h) C/N ratio (3, 6 9) on nitrogen removal efficiencies in a bench top sequencing batch reactor treating slaughterhouse wastewater were investigated under different operating conditions: condition I, the reaction comprises an aerobic/anoxic phase II, anoxic I/aerobic/anoxic II phases (with pre-denitrification). The greatest percentages obtained CT range from to h ratios 3 6, with mean efficiency values 80.76% 85.57% I 90.99% 91.09% II....
Estimation of evapotranspiration is a key factor to achieve sustainable water management in irrigated agriculture because it represents use crops.Satellite-based estimations provide advantages compared direct methods as lysimeters especially when the objective calculate at regional scale.The present study aimed estimate actual (ET) scale, using Landsat 8 -OLI/TIRS images and complementary data collected from weather station.SEBAL model was used South-West Paraná, region composed dry...
Este trabalho teve o objetivo de avaliar desenvolvimento, a produção e qualidade sanitária da cultura alface irrigada com águas residuárias originadas suinocultura piscicultura. Os tratamentos avaliados foram: T1 - água origem subterrânea adubação suplementar; T2 residuária viveiro peixes alimentados ração; T3 originária lagoa estabilização dejetos suínos, T4 cultivo algas, alimentada resíduo biodigestor dejeto suíno. não apresentaram diferenças significativas para altura alface, diâmetro...
The objective of this research was to evaluate the performance aquatic macrophyte Eichhornia crassipes applied in situ a slaughter house treatment system, located west Paraná state, Brazil, regarding nutrients removal and organic matter. Moreover, it aimed obtain data from production, management composting practices biomass generated system. During 11 months macrophytes development, physic chemical parameters were monitored plant density controlled by periodical excess biomass, which weekly...
Analisar a qualidade da irrigação, além de avaliar seu bom funcionamento, é uma forma verificar viabilidade sua implantação e operação. Como uniformidade distribuição um dos parâmetros mais utilizados para essa avaliação, este trabalho objetivou utilizar técnicas engenharia qualidade, usando o índice capacidade do processo (Cpl) água em sistema irrigação por aspersão convencional. Os ensaios foram conduzidos no Núcleo Experimental Engenharia Agrícola, UNIOESTE, com dois aspersores modelo...
O presente trabalho foi realizado visando à avaliação do movimento nitrato (N-NO-3) proveniente de águas residuárias frigorífico, em colunas solo. No experimento, foram utilizados dois tipos solo, um textura argilosa e outro arenosa, ambos corrigidos com calcário, quatro PVC, 500 mm comprimento 75 diâmetro. Após saturação CaCl2 0,01 M, mantida na parte superior cada coluna, por meio frasco Mariotte, uma lâmina 100 da água residuária, que permitiu total infiltração correspondente a 2,5 vezes...
The use of anaerobic reactors with media support in the treatment wastewater from cassava starch industry has emerged as a viable option because it allows application high organic loads and significant reduction HDT needed for treatment. This research aimed at studying process biodigestion two bamboo support, effluent starch, by evaluating their performance. used present following diameter: length ratio, 1:6 1:3. applied to systems were 0.519, 1.156, 1.471, 3.049, 4.347, 4.708...
ABSTRACT: The objective of this study was to evaluate the use statistical quality control tools in analysis uniformity a microsprinkler irrigation system. For Christiansen coefficient (CUC) and distribution (DU) were statistically analyzed by means Shewhart charts process capability index (Cp). experiment 25 tests carried out with single micro sprinkler subsequently seven different spacing between sprinklers simulated. Control contributed diagnosis treatments be under satisfactory outcomes....
The current study used statistical methods of quality control to evaluate the performance a sewage treatment station. concerned station is located in Cascavel city, Paraná State. evaluated parameters were hydrogenionic potential, settleable solids, total suspended chemical oxygen demand and biochemical five days. Statistical analysis was performed through Shewhart charts process capability ratio. According charts, only BOD(5.20) variable under control. Through ratios, we observed that except...
The determination of volumetric water content soils is an important factor in irrigation management. Among the indirect methods for estimating, time-domain reflectometry (TDR) technique has received a significant attention. Like any other technique, it advantages and disadvantages, but its greatest disadvantage need calibration high cost acquisition. main goal this study was to establish model TDR equipment, Trase System Model 6050X1, estimate Distroferric Red Latosol. carried out laboratory...
When cultivated areas are used with intense agricultural production, the soil presents spatial and temporal alterations in its hydrophysical attributes so that economical viability of production depends on those attributes, requiring detailed studies consequently about variability soil. Thus, objective this work was to evaluate saturated hydraulic conductivity water infiltration soil, an area 20 ha, characterized by intensive grain a grid 50 x m grating, using Guelph Permeameter. In...
The generalized extreme value distribution (GEV) has had great acceptance for discretion of the maximum natural events. Previous studies show that GEV fits values closer to reality when there is need extrapolation sampling data longer periods returns. In order contribute planning activities are influenced by intensity precipitated water, we adjusted a model probability heavy rain through GEV, using LH moments estimating its parameters and statistical test proposed Wang (1998) checking...
