| This trial evaluated the addition of Lactobacillus plantarum, L. brevis and Enterococcus faecium combo additive against a control treatment. The silages were made in laboratory silos that were stored for 30, 60, 90 or 120 days before opening. We evaluated the chemical composition of the forage before and after ensiling and the fermentative losses of silages. The additive decreased (p < 0.01) effluent production (11.4 kg ton-1) compared to control silage (14.0 kg ton-1), but it increased (p < 0.01) the Neutral Detergent Fiber (NDF) and Acid Detergent Fiber (ADF) from 45.6% and 24.5% to 47.0 and 25.1% for control and additive silages, respectively. The storage periods affected (p < 0.01) effluent production, Dry Matter Losses (DML), NDF,... |

| The objective of this study was to measure ammonia volatilization from surface application of pig slurry, poultry litter, urea and no fertilization. An experiment was conducted in a randomized block design, in plots repeated over time, with four treatments and four replications. The fertilizers tested were: mineral fertilizer (70 kg ha-1 N, 100 kg ha-1 P2O5 and 30 kg ha-1 of K2O, as urea, triple superphosphate and potassium chloride, respectively), pig slurry (200 m³ ha-1 applied in November 2008 and 200 m³ ha-1 applied in April 2009) and poultry litter (10 t ha-1 applied in November 2008 and 10 t ha-1 applied in April 2009). Five evaluations were performed with 24-hour intervals. Foams were used with glycerin and sulfuric acid, internally fixed in PET... |

| Abstract: Asian soybean rust, caused by the fungus Phakopsora pachyrhizi, is the most severe disease of the crop and can cause yield losses of up to 90%. The disease was first reported in Brazil in 2001. Epidemics of the disease are common in the country, where the fungus can survive year-round. Regulatory measures to reduce the inoculum between seasons and avoid late-season soybean have been adopted to manage the disease. Disease control has relied mainly on chemical control, but a lower sensibility of the fungus to fungicides has been reported in Brazil. Major-resistance genes have been mapped and incorporated into the cultivars. With the reduced efficacy of the fungicides, the adoption of integrated measures to control the disease will be important for... |

| ABSTRACT Assuring the quality of mechanical soybean harvesting is crucial to ensure that investment in other stages of crop production is converted into profit for the farmer. Because the quality of this operation is related to decreased losses, which may be affected by the combine header used and by the harvesting speed, the aim of the present study was to assess the quality of mechanical soybean harvesting in the Southern Cone of Rondônia, using harvesters with different combine headers and travel speeds via statistical process control. The experiment was performed during the 2015/16 harvest in an agricultural area of the municipality of Cabixi, RO, located at the geographical coordinates 13° 27’ S and 60° 41’ W. The study was designed based on the... |

| A model to estimate damage caused by gray leaf spot of corn (Cercospora zea-maydis) was developed from experimental field data gathered during the summer seasons of 2000/01 and during the second crop season [January-seedtime] of 2001, in the southwest of Goiás state. Three corn hybrids were grown over two seasons and on two sites, resulting in 12 experimental plots. A disease intensity gradient (lesions per leaf) was generated through application, three times over the season, of five different doses of the fungicide propiconazol. From tasseling onward, disease intensity on the ear leaf (El), and El - 1, El - 2, El + 1, and El + 2, was evaluated weekly. A manual harvest at the physiological ripening stage was followed by grain drying and cleaning. Finally,... |

| This study was carried out, at Dept. of Agric. Eng., Faculty of Agric., Mansoura Univ., Egypt during 2014 spring season, to design and evaluate a cutting prototype performance and production as a date palm leaves components (fronds, leaflets and spines). The tested treatments include saw speed (167.5, 251.2, 334.9 and 418.7 rad s-1), saw teeth inner spacing (4, 5 and 8 mm) and feeding speed ratio (1:1, 1:1.25, 1:1.67 and 1:2.50). The study concluded that the optimum operation conditions of saw speed of 334.9 rad s-1, saw teeth inner spacing of 8 mm and 1:1.25 feeding speed ratio achieved cut fronds productivity of 1051.5 m h-1, cut leaflets and spines productivity of 183.86 kg h-1, cutting leaflets efficiency of 99.32%, leaflet losses of 0.68 %, frond... |

| A redução da produção de leite em bovinos é um dos aspectos majoritários na composição total do valor de impacto econômico provocado por R. (B.) microplus. Portanto, o objetivo deste estudo foi estimar a perda decorrente da carga parasitária, observada em uma propriedade produtora de leite na região central de Minas Gerais. Para tal, foram consideradas 30 contagens de carrapatos, distribuídas de maneira uniforme durante o período de um ano, em um rebanho bovino com 74 vacas de composição racial 3/4 Holandês x Zebu, mantidas sob sistema de produção intensivo em pastoreio. A partir dos dados observados, foi possível estimar que 937.968 teleóginas completaram o repasto sanguíneo e foram responsáveis pela redução de 6.678 litros de leite durante o período... |

| Because of their potential for N2 biological fixation, legumes are an alternative source of nitrogen to crops, and can even replace or supplement mineral fertilization. A greenhouse experiment was carried out to evaluate temporal patterns of velvet bean (Mucuna aterrima) green manure release of nitrogen to rice plants, and to study the fate of nitrogen from velvet bean in rice cultivation. The isotopic dilution methodology was used. Treatments consisted of a control and 10 incubation periods of soil fertilized with 15N-labeled velvet bean (0, 20, 40, 60, 90, 120, 150, 180, 210, and 240 days). The plant material was previously chopped, sifted (10 mm mesh sieve) and oven-dried (65ºC). Incubation of the plant material (2.2 g kg-1 soil) was initiated by the... |

| Sugar cane silages are characterized by extensive yeast activity, alcohol production and great dry matter - DM - losses. Better knowledge of the fermentation process is fundamental to the development of efficient ensilage techniques for this forage. This study evaluates temporal changes in chemical composition, DM losses and epiphytic microflora in sugar cane silage. Mature sugar cane, variety RB835486 (12 months of vegetative growth), was hand harvested, processed in a stationary chopper and ensiled in 20-L plastic buckets provided with valves for gas release and a device for effluent collection. Laboratory silos were kept at ambient temperature and sampled after ½, 1, 2, 3, 7, 15, 45, 90, 120 and 180 days. Ethanol concentration reached 6.4% in DM after... |

| Fruit yield and bacterial wilt symptoms of eggplant genotypes CNPH006, CNPH171, CNPH658, CNPH778, CNPH783, and CNPH785 were quantified in soil naturally infested with Ralstonia solanacearum(race 1, biovar 3) in Brasília, Brazil.Exceptfor CNPH778, all genotypes developed at least one typical wiltedplant. Besides wilt,other symptoms considered for assessing levels of tolerance/resistance among genotypes wereplant death (CNPH006, CNPH171, CNPH658 and CNPH783), leaf chlorosis(CNPH785) and plant dwarfing (all genotypes). The occurrence of bacterial ooze on cut stems was observed in all plants grown in infested beds, including those that did not exhibit wilt symptoms. Plants grown simultaneouslyin noninfested beds of the same dimensions and soil characteristics... |
