Condições hidrológicas de uma bacia hidrográfica com diferentes usos do solo na região de taquaritinga, SP

In areas where human activities, as agriculture, are developed land use contributes to physical, chemical and biological characteristics of water. This study aimed to identify physical and chemical variations of the water monitoring network in 4 first magnitude watersheds with different land use/occupation in the hydrographic basin of the Glori Farm Creek in the city of Taquaritinga, State of Sao Paulo, from February to July, 2005. The methodology consisted of weekly sample water collections to naalyze turbidity, temperature, dissolved oxygen, pH and electric conductivity. The characterization of the hydrological conditions of the watersheds showed that agricultural activities, including the productive system of the sugarcane cultivation, have affected the quality of water resources.

Fungigação no controle do mofo branco e produtividade do feijoeiro em condições de cerrado brasileiro

The aim of this research was to evaluate the white mold severity (Sclerotinia sclerotiorum (Lib.) of Bary), bean production components and yield (Phaseolus vulgaris L.), variety Perola, according to the application of procimidone fungicide (Sialex 500), through fungigation (center pivot) and automotive sprayer (Uniport). The study was carried under field production commercial conditions, in Primavera do Leste - MT - Brazil. The experiment consisted of 5 treatments (with 4 repetitions of 4 ha each), all with two procimidone applications (1.2 kg ha-1 each application, same as, 0.6 kg a.i. per hectare) to the 42 and 52 days after seeding. The water depths of 5.5 and 11.0 mm were tested in the application through central pivot (this had your checked uniformity), providing volumes of 55.000 and 110.000 L ha-1, respectively, and the volumes of 120 and 200 L ha-1 in the automotive sprayer. The severity of disease was evaluated by the percentage of the area affected by plant damage using diagramatic grade scale of white mold severity, as described by Azevedo (1998). The values were used to calculate the area under the disease progress curve (AUDPC). They were also analyzed, the number of the fungus apothecia during the crop cycle and the residual sclerotias weight in harvest. On this occasion, it was also evaluated the crop yield parameters: number of plants per plot (final stand), pods per plant, grains per pod, medium weight of 200 grains and productivity of grains. The AUDPC values, apothecia to 42, 49 and 56 days after seeding, sclerotias in 2 soil kg and the crop productivity parameters were submitted to the variance analysis and Tukey Test at 0.05 of probability. This test was also applied in the comparison among the different fungicide application methods, independent of spray volumes in each one. The statistical processing was accomplished by STAT program. The results showed that weren't differences among application techniques studied in relation to productivity parameters, however, best white mold control, smaller apothecia number to 49 and 56 days after seeding and smaller weight of residual sclerotias in the harvest were obtained with the fungigation, independently of the spray volume used.

Sistema de cuentas ambientales y económicas del agua. Borrador final

El Sistema de Cuentas Ambientales y Económicas del Agua (SCAE-Agua) proporciona el marco conceptual para la organización coherente y consistente de la información hídrica y económica. El presente manual está basado en el Sistema de Cuentas Ambientales y Económicas 2003 (Naciones Unidas, 2003) que describe la interacción entre el sistema económico y el medio ambiente, cubriendo todo el espectro de los recursos naturales y el medio ambiente. Tanto el SCAE-2003 como el SCAE-Agua, tienen como marco básico el Sistema de Cuentas Nacionales 1993 que es el sistema estándar para la compilación de estadísticas económicas y de los indicadores económicos derivados, entre los que destaca el Producto Interno Bruto.

Efeito das condições pré-abate sobre a qualidade da carne de suínos pesados

The objective of this study was to evaluate pig fasting time at the farm (FT= 9, 12, 15 or 18 hours) and pig position into the pig lorry compartment on pork quality through liquid drip loss (DLL), pH1 evaluated at 45 minutes post slaughter and pHu evaluated 24 hours post slaughter. One hundred ninety two females, weighing 133±11 kg, from two farms were used. Pig locations were evaluated on truck compartment considering front, middle and rear (TCL) position and top or botton decks (LUD). The following effects were considered in the statistical model: block (BL= farm), FT, TCL, LUD and the interaction between BL and FT. The FT affected significantly the pH1 of Longissimus dorsi (LD) muscle, and pHu of Semispinalis capitis (SC), Longissimus dorsi (LD) and Semimembranosus (SM) muscles. Fasting time at farm equal or shorter than 12 hours resulted in carcasses with lower pHu values at LD and SM muscles and fasting time above 15 hours resulted in higher pHu on SC. There were no observed effect (p>0.05) of the evaluated sources of variation on DLL. TCL affected pH1 of SC, LD and SM muscles, and pHu of LD and SM muscles. Pigs located in middle or rear position in the lorry had no difference in pH1 of the evaluated muscles. But pigs located in the middle position of the lorry had greater values of pHu on LD and SM. It is stated that pigs fasting time at farm need to be close to 15 hours in aim of obtain higher frequency of pHu values in the normal range (5.55
