Additive containing homo and heterolactic bacteria on the fermentation quality of maize silage - doi: 10.4025/actascianimsci.v35i4.18833 Animal Sciences
Junges, Daniel; Universidade de São Paulo; Schmidt, Patrick; Universidade de São Paulo; Novinski, Charles Ortiz; Universidade Federal do Paraná; Daniel, João Luiz Pratti; Universidade de São Paulo.
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,...

Asian soybean rust in Brazil: past, present, and future PAB
Godoy,Cláudia Vieira; Seixas,Claudine Dinali Santos; Soares,Rafael Moreira; Marcelino-Guimarães,Franscismar Correa; Meyer,Maurício Conrado; Costamilan,Leila Maria.
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...

Can combine headers and travel speeds affect the quality of soybean harvesting operations? AGRIAMBI
Menezes,Patricia C. de; Silva,Rouverson P. da; Carneiro,Franciele M.; Girio,Lucas A. da S.; Oliveira,Mailson F. de; Voltarelli,Murilo A..
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...

Critical-point yield model to estimate yield damage caused by Cercospora zea-maydis in corn Trop. Plant Pathol.
Reis,Erlei M.; Santos,Jones A.P.; Blum,Marta Maria C..
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,...

Fate of nitrogen (15N) from velvet bean in the soil-plant system Scientia Agricola
Scivittaro,Walkyria Bueno; Muraoka,Takashi; Boaretto,Antonio Enedi; Trivelin,Paulo César Ocheuze.
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...
