title: Water stress daily index in the bean plant irrigated with saline water

description: Abstract With the objective of determining the yield of bean cv. Talismã as a function of the daily water stress index, an experiment was conducted in drainage lysimeters under greenhouse conditions at the Universidade Federal de Viçosa, MG. Treatments were arranged in a completely randomized design and consisted of seven leaching fractions corresponding to 40, 31, 25, 23, 16, 14 and 3% of the irrigation water depth. Fresh water (0.07 dS m-1) was used for the leaching fraction of 3%, and saline water (2.0 dS m-1) for the other treatments, both with three replications. The cv. Talismã bean showed to be sensitive to salinity, and the highest efficiency of water use, under saline conditions, was obtained for the leaching fraction of 31%. However, the efficiency tended to decrease as the leaching fractions were reduced. The daily water stress index showed to be efficient to determine the relative yield of the bean plant under saline conditions.

title: Surgical Site Infection after Cesarean Delivery in Times of COVID-19

description: Abstract Objective To analyze effects of the COVID-19 pandemic on the consumption of personal protective equipment and products (PPEP), as well as the frequency of surgical site infection (SSI) among non-COVID-19 patients submitted to cesarean sections. Methods A retrospective study was conducted in a maternity unity of a public teaching hospital which was not part of the reference service for COVID-19 treatment. It compared PPEP consumption and the occurrence of SSI after cesarean sections in monthly periods before and after the occurrence of the first case of COVID-19 in Porto Alegre, state of Rio Grande do Sul, Brazil. Personal protective equipment and products consumption was measured as units of masks, gloves, gowns, and caps, and use of alcohol-based products or soap for hand sanitation asml/patient/day. The SSI index was calculated as the proportion of cases of SSI over the number of cesarean sections performed monthly during the study period. Results There was an increase in all measured items of PPEP, with consumption of disposable masks with a median of 1,450 units in the pre-COVID period, and of 2550 in the post-COVID period (a 75.9% increase). A decrease of 49% in SSI was detected, with a median of 1.74 in the pre-COVID period and of 0.89 in the post-COVID period. Conclusion The increase in consumption of PPEP could be a result of safer practices adopted by healthcare workers with the advent of COVID-19, of which the following reduction in the occurrence of SSI could be a direct consequence. Despite the severity of the crisis, one could state that extreme situations can lead to valuable reflections and opportunities for improvement.

title: Soil attributes as indicators of the stabilization process of erosion in gullies at different formation stages in the southeast region of Brazil

description: Abstract Water erosion is one of the main forms of soil degradation, causing economic, environmental, and social damage. This study evaluated the effects of different formation stages of gullies (initial - IG; juvenile- JG; mature - MG; and senile - SG) on the chemical, organic carbon and microbiological attributes of soil, using a secondary forest (SF) and two areas of pasture as references in the “Mar de Morros” environment of the Brazilian Atlantic Forest biome. Soil samples (depth 0-0.05 m) were collected at the end of the rainy and dry seasons. Gullies in different stages of formation promote a decrease in soil fertility and modification of microbiological attributes, particularly when compared with secondary forest areas. Reductions of over 60% in total organic carbon (TOC), oxidizable organic carbon (POXC), FDA activity, β-glycosidase, acid phosphatase, C and N from microbial biomass, basal soil respiration (BSR) and glomalin-related soil protein (GRSP) were observed in gullies in early (IG) and intermediate (JG and MG) stages when compared to SF. It was found that the effect of erosion on soil chemical and microbiological attributes is more intense in gullies in the initial and intermediate stages compared with those in the senile stage (SG). Using multivariate PCA, the microbiological and chemical attributes of the soil are discriminated between gullies with distinct formation stages. Chemical attributes, TOC, POXC, FDA activity, β-glycosidase, acid phosphatase, MBC and MBN, BSR, and GRSP are good indicators for evaluating the process of erosion stabilization in gullies.

title: Economic analysis of the use of saline water in melon cultivation

description: Abstract In Brazil, the State of Rio Grande do Norte is the largest producer of melons for exportation where in irrigation waters of different salinity are utilized. With the objective of studying economical viability of two melon cultivars (Orange Flesh and Goldex), irrigated with waters of high salinity in combination with different doses of K2O, two experiments were conducted during the years of 2003 and 2004, in the municipality of Mossoró - RN. In the first experimente water of EC of 0.80 and 3.02 dS m-1 were used in two cultivars fertilized with 273 kg ha-1 of K2O while in the second experiment waters of EC 0.52 and 2.41 dS m-1 combined with diferente doses of K (218, 273, 328, 383 and 438 kg ha-1 of K2O) in the cultivar Goldex were tested. The experiments were conducted in a radomized blocks with four replications. The treatments arranged in split plot scheme in the second experiment. Contrary to cultivar Goldex, use of high salinity water (EC = 3.02 dS m-1) in the irrigation of cultivar Orange Flesh showed to be economically viable. In case of cultivar Goldex irrigated with saline water (EC = 2.41 dS m-1) the production economically viable was only possible when higher doses of potassium were applied.

title: Floristic Composition of Buah Hitam Habitats in Lowland Tropical Mixed Forest of West Papua, Indonesia

description: Abstract The biotic factors in tropical lowland forests, especially vegetation, are essential for the sustainable management of forest products. The study aimed to investigate the species richness and diversity of trees in Buah Hitam habitats, and study the tree communities formed by tree species by collecting the data from the habitats of Buah Hitam in Wondama Bay, West Papua, Indonesia viz. primary forest, secondary, and the garden with plots 9, 9, and 8 respectively. The species richness and diversity were higher in the primary forest than that in the secondary and garden. Tree communities indicated that the primary forest differed from the secondary and garden. The habitat types have been shaped as a result of anthropogenic activities for decades. This finding is necessary to set the consensual programs by the government and local people particularly in conservation and sustainable management for the three habitats.

title: Soil chemical characteristics influenced by addiction of swine wastewater

description: Abstract The objective of the present work was to study the effects of the application of swine wastewater (SW) on some chemical characteristics of Latosol and to evaluate the variation in the forms of nitrate and ammonium in relation to the mineralized nitrogen, under different conditions of temperature and water contents in the soil. Samples of Latosol were mixed with SW in amount corresponding to 400 kg ha-1 of nitrogen and incubated under different conditions of temperature and water contents. At 3, 6, 12, 24, 48 and 96 days after incubation the concentrations of ammonium and nitrate were quantified and at 3 and 96 days analysis electrical conductivity, pH, total nitrogen and carbon were also evaluated. The microorganisms accomplished larger nitrification in the temperature of 25 °C. The application of SW contributed to the increase of the pH and of the electrical conductivity, at 3 days after incubation of the soil. On average, at 96 days after incubation there was an increase in electrical conductivity of soil with and without SW.

title: Nutrition of coffee plants under fertirrigation with urban wastewater

description: Abstract This study aimed to evaluate the effects on nutrition of Arabic coffee (Coffea arabica) by fertirrigation using a drip irrigation system with untreated urban wastewater (UW), without application of chemical fertilizers; confronted with irrigation using fresh water (FW) with chemical fertilizers; The study was carried out at the Experimental Unit of Wastewater Treatment and Irrigated Agriculture, of UFV, during 18 months. The fertirrigated treatments (MR’s) consisted of five depths of UW (406, 515, 798, 924 e 1071 mm). FW with fertilization (MC) was used in another treatment. The nutrient (N, P, K, Ca, Mg e S) contents of the leaf were evaluated every three months. The results obtained showed that: the MR presented Mg content of the leaves always higher than MC and contents of Ca and P during the first 12 months. There was no difference in N and S contents of the leaves for the MR’s and MC treatments and the K contente of the leaf for MC was higher than for MR.
