This study aimed to evaluate of productive characteristics in integrated livestock-crop systems with or without winter grazing and fertilization strategies. The experimental design used was a randomized complete block split plots (3 replications per treatment). Treatments were composed four strategies (COMB = combination for both soybeans pasture applied during the phase; FSBP REC recommended fertilizations soybean their respective phases TRAD traditional recommendation, N phase P K...
Current fertilizer recommendations often neglect nutrient cycling across crop rotations. This study aimed to assess the decay rate and (N, P, K) release patterns of sorghum, black oat, corn residues their effects on yield in an integrated crop-livestock system. The experiment used factorial treatments based two sward heights (high low) nitrogen fertilization levels (N-Pasture at 200 kg N ha-1 N-Corn 0 ha-1. Litter bags were collected various intervals from each measure decomposition rates....
This study evaluated the effects of two chemical additives or a microbial inoculant on composition and DM losses in whole-plant soybean silage. One-hundred twenty mini-silos were used completely randomized design experiment with following treatments: water without chloride (control, CON); (INO); additive containing 35–45% formic acid (FA type); another 50–60% propionic (PA type). Data analyzed using mixed models SAS, treatment differences by orthogonal contrasts: C1 = CON vs. (INO + FA type...
ABSTRACT: This study aimed to evaluates some physical chemical aspects of chilled raw milk that meet Brazilian quality standards in smallholder farms from southern Region Brazil. The fat content, crude protein (CP), total solids (TS), somatic cell count (SCC), and plate (TPC) the 78 was analyzed between Oct 2014 Feb 2017. It found 96% samples met regulations for 87% CP, 91% TS. mean values TPC SCC were higher than maximum limits established by regulations. Smallholder Southern Brazil produce...
ABSTRACT: In integrated crop-livestock systems, overseeding annual summer pastures over grain crops can reduce forage shortages in autumn without altering production. This study evaluated the influence of pearl millet (Pennisetumglaucum L.) and sudangrass (Sorghum Sudanese) overseeded on a soybean (Glycine Max) crop or no-tillage seeding after harvest productive aspects pasture. The experimental design was randomized block with treatments 2 × factorial arrangement (pearl sudangrass, full...
Objetivou-se com este estudo avaliar o estabelecimento de lavoura sorgo para silagem ou sem a utilização tratamento sementes. Adotou-se delineamento em blocos casualizados, dois tratamentos: presença e ausência do Neste as sementes foram tratadas Standak (Fipronil-0,250 g/Kg semente), Cropstar 5 mL/kg (Imidacloprido-0,450 g/kg sementes+Thidiocarb 1,350 sementes), Derosal (Carbendazin 0,300 sementes+Thiran 0,700 sementes) 3 mL PackSeed (Spraytec®). Foram avaliadas seguintes variáveis: i)...
Current fertilizer recommendations often neglect nutrient cycling across crop rotations. This study aimed to assess the decay rate and (N, P, K) release patterns of sorghum, black oat, corn residues (omitido) in an integrated crop–livestock system. The experiment used factorial treatments based on two sward heights (high low) nitrogen fertilization levels (N-pasture at 200 kg N ha−1 N-corn 0 ha−1). Litter bags were collected various intervals from each measure decomposition rates. results...
O controle leiteiro é uma ferramenta de gestão alta relevância dentro da bovinocultura leite, a qual tem por objetivo acompanhar situação produtiva das vacas forma individual e todo o lote, bem como estabelecer melhorias diagnosticar erros. Este manejo permite ainda, obter um melhor resultado produtivo econômico do rebanho. No presente estudo foi realizado acompanhamento produção leiteira no Tambo leite Unipampa, registrando diariamente os resultados posteriormente comparando-as com...
Objetivou-se com este trabalho determinar a liteira depositada, oferta de forragem, seus os componentes estruturais e valor nutricional em pastagens azevém manejadas sob diferentes alturas. Adotou-se o delineamento blocos casualizados quatro alturas pastejo (5; 10; 15 20 cm) ausência (30 repetições, totalizando unidades experimentais. Sessenta dias após implantação cv. Estanzuela 284 iniciou-se utilização ovinos testers, pastejando por 45 dias. Posteriormente foi realizada amostragem para...
ABSTRACT: The objective was to evaluate the animal production and ingestive behavior of steers fed different supplements during growth phase in Aruana grass, influence this supplementation on performance feedlot phase. treatments consisted three growing phase: mineral salt (0.12 g/kg body weight - BW), low intake energy-protein supplement (1.26 medium (3.76 BW). Forage canopy characteristics, production, pasture were evaluated a completely randomized design with replicates (paddocks)....
This study aimed to evaluate levels of potassium and nitrogen fertilizer inversion in the black oat crop on corn yields. The experimental design was a randomized block with subdivided plots three repetitions. treatments were four fertilization strategies, two managements (forage cover crop). strategies involved winter (oats) summer (corn) application, respectively, following combinations (200-0; 150-50; 50-150; 0-200 kg N ha-1) (80-0; 60-20; 20-60; 0-80 K ha-1). We evaluated morphological...
Nitrogen (N) losses by leaching are significant in terms of environmental contamination. Thus, attention has been given to urination points ruminant urine because they contain high levels N. Integrated crop-livestock systems (ICLS), turn, seek intensify production and, at the same time, make more sustainable. Therefore, it is crucial know behavior N boost its cycling consequently, minimize impacts (environmental and economic). The objective this study was evaluate from bovine a mixed pasture...
Carrot is an edible tuberous root with high economic value in Brazil. seeds may present uneven germination due to the presence of inhibitors epithelium. The cover crops growing area generate allelopathic compounds, potential inhibit or stimulate cultivated species. work objective was verifying effect pigeon bean extract levels on and development carrot seedlings. research conducted a completely randomized design, 3x5 factorial scheme (cultivars,Danvers, Flakker Giant Nantes Milena...
O objetivo do trabalho foi estimar a diversidade genética e avaliação de cultivares trigo para ambientes com sem estresse hídrico em estágio inicial. delineamento experimental inteiramente casualizado esquema fatorial 2 x 26, o primeiro fator excesso segundo 26 trigo.

Currently, floriculture has drawn the attention of farmers as an option for income on their properties. The gladiolus is a culture destined to produce cut flowers, widely used by florists and decorators. Despite its wide use, there still not much information about behavior different cultivars in some places cultivation country possibility producing quality stems. In this sense, objective work was evaluate stems from subtropical environment. performed city Chopinzinho/PR. experiment conducted...
