| No sistema de semeadura direta, a dessecação que antecede à semeadura (manejo) é uma das operações mais importantes para maximizar o crescimento inicial das culturas e minimizar a interferência das plantas daninhas no início do ciclo. O objetivo do trabalho foi avaliar o efeito de diferentes sistemas de manejo que antecede à semeadura da soja, no município de Iguaraçu, Paraná, no ano agrícola de 2004/2005. Foram comparados cinco épocas de manejo (10, 7, 5, 3 e o dias, antes da semeadura), com três tratamentos herbicidas (glyphosate 1080 g, glyphosate + flumioxazin 1080 + 25 g ha-1 e glyphosate + flumioxazin 1080 + 40 g ha-1), em relação à velocidade de dessecação, infestação inicial de plantas daninhas e desenvolvimento e produtividade da soja.

| Conservation tillage systems have been used during recent years in many areas of Iran. In this study, the effect of conservation tillage on soybean yield, yield components and phenological characteristics was evaluated in Golestan province located at the northern Iran. Four different treatments including conventional tillage (CT), minimum tillage (MT), no- tillage with no-till planter (NT-Planter) and no-tillage with no-till grain drill (NT-Grain Drill) were considered. A randomized complete block design with four replications was designed for the experiment. Soybean yield and yield components and some phenological characteristics were measured. Data were analyzed using SAS software and Duncan’s multiple range tests was used to compare the means. The... |

| ABSTRACT The aim of this research was to study the effect of thermal and non-thermal processing methods on chemical composition, quality indicators and apparent digestibility of soybean nutrients. For this, four processing methods (unprocessed, extruded, thermal, and gamma radiation) were applied on two soybean varieties (Katol & Caspian). Rations were formulated based on kinds of soybean (processed and unprocessed). The experiment was continued using 600 male Ross broiler chickens during 3 feeding phases (starter, grower, and finisher). Traits were measured and analyzed with the Lsmeans procedure by SAS software. The results showed the interaction effects of soybean varieties and processing methods were significant on the crude fiber, calcium, and... |

| Soybean plants cultivated with 50, 100 and 200 mM of NaCl, revealed that root growth was less affected by salinity than shoots. Salinity led to a reduction in leaf area and an increase in water content of the roots. These factors could contribute to the adaptation of the plant, improving its hydration. Although nitrate and free amino acid levels were reduced by salt treatment in roots, protein content of leaves was not altered. Salinity led to alterations in xylem amino acid composition, with increases in Ser, Ala, Gaba and Pro and a decrease in Asn. Similar changes were seen for Asn and Ser in roots together with a much stronger increase in Gaba. It is suggested that the decline in Asn reflects its conversion to Ala and Gaba (via Glu) in the roots while... |

| Field experiment was conducted at Agricultural and Natural Resources Research Center of Golestan Province, Iran, to determine the effects of tillage system and weed management regime on yield and weed populations in soybean ( Glycin max L.). The experimental design was a split plot where the whole plot portion was a randomized complete block with three replicates. Main plots were tillage system: 1- No-till row crop seeding, 2- No-till seed drilling, 3- Tillage with disc harrow and drill planting, 4- Tillage with chisel packer and drill planting. The subplots were weed management regimes: 1-Weed control with herbicide application, 2- Hand weeding, 3- Herbicide application plus hand weeding, and 4- Non-weeding. Results indicated that the main effects of... |

| Since the anti-inflammatory, antidiabetic and hypolipidemic effects of soy isoflavones may be mediated by activation of peroxisome proliferator-activated receptors (PPAR), the present study investigated whether the methanolic fractions obtained from soybean seeds (E1) and soybean seed coats with hypocotyls (E2) could influence PPARα, PPARγ and PPARβ/δ transcriptional activity. The isoflavones from E1 and E2 were quantified by HPLC analysis. E1 and E2 were rich in isoflavones (daidzin, glycitin, genistin, malonyldaidzin, malonylglycitin, malonylgenistin, daidzein, glycitein, and genistein). Moreover, E1 and E2 showed no evidence of genetically modified material containing the gene CP4 EPSPS. To investigate PPAR transcriptional activity, human promonocytic... |

| Protozoa population, microbial synthesis efficiency and rumen degradability of dry matter and neutral detergent fiber in cattle fed on diets with different lipid rates were evaluated. Nine 16-month-old Nelore young bulls, cannulated in the rumen and duodenum, weighing 232 ± 35 kg, were used in the trial. Experimental design consisted of a 3 x 3 square in triplicate, comprising the following treatments: 2, 4 and 6% lipid in diet. In situ degradability was assessed by rumen incubation of corn silage, soybean, soybean meal and citrus pulp during 0, 3, 6, 12, 24, 48, 72 and 96h. The flow of microbial nitrogen and microbial efficiency were not influenced (p > 0.05) by the inclusion of lipid levels in the diet. When the animals received diet with 4%... |

| Arsenic (As) and Fluoride (F) are present in many soils, affecting crops and posing risks in the food chain. We performed pot experiments on spiked soils enriched in these elements either individually or simultaneously, over a wide range of concentrations. Soybean biomass production, grain yield, As and F accumulation and distribution within the plant, and the antioxidant response to these stresses were analyzed. Arsenic was more toxic than F. At As levels >35 mg/kg and F levels >375 mg/kg, yield loss reached 60% and 30%, respectively. At the highest dose of As plants died within 2 weeks, whereas F showed no lethality. When they were applied simultaneously, detrimental effects were more important. As and F in plants increased in all soybean organs... |

| ABSTRACT The objective of this study was to evaluate the effects of polymer coated slow-release urea (SRU) in high-forage diets of beef steers on nutrient intake and digestibility, ruminal fermentation, microbial protein synthesis, and energy balance. Eight 24-mo-old rumen-fistulated castrated Nellore steers (average body weight = 418.0±40.0 kg) were used in a replicated 4 × 4 Latin square design. Animals were randomly distributed to receive one of the following diets: no urea inclusion; 1.0% inclusion of feed grade urea in the diet (dry matter [DM] basis); 1.0% inclusion of slow-release urea 1 in the diet (DM basis); and 1.0% inclusion of slow-release urea 2 in the diet (DM basis). Slow-release urea 2 had a similar composition to that of slow-release urea... |

| Statistical methods are used to study relationships between research expenditures (adjusted for inflation) made from producer checkoff programs and soybean yields and net revenues in the United States for the years 1978 – 2007. Results presented are for yield and net revenue data and research expenditures for the entire United States. We find that research expenditures over the years 1994 to 2007 are responsible for a 0.95 bushel per acre per year increase in soybean yields. We calculate net producer revenues to be about $17 per acre higher than would have been the case without the soybean research checkoff expenditures. |

| Soybean {Glycine max) is currently the most widely grown and rapidly expanding crop in Argentina, and brown spot caused by Septoria glycines is a major foliage disease that affects this crop. Triáis in the 2005 and 2006 growing seasons were undertaken using soybean (Glycine max) cv. Nidera A4800 RR. A randomized complete block design was used with four replicates. Two biological fungicides, based on Bacillus subtilis or B. pumilus, and four conventional fungicides, pyraclostrobin in combination with epoxiconazole (Opera 25 SC, BASF Argentina), azoxystrobin (Amistar 25 SC, Syngenta Argentina), trifloxystrobin in combination with cyproconazole (Sphere 267,5 EC, Bayer, Argentina), and tebuconazole (Folicur 25 EC, Bayer, Argentina), were evaluated. Fungicides... |
