2. Phenotypic variance of black oat growing in crop seasons reveals genetic effects predominance
Abstract: This work aimed to determine variance components and genetic parameters, as well as phenotypic, genetic and environmental correlations among black oat (Avena strigosa) families grown in different crop season. Seventy-six black oat families and three controls (BRS Madrugada, BRS Centauro, BRS 139 Neblina) were evaluated in two crop seasons (2016 and

3. Crop coefficients of tropical forage crops, single cropped and overseeded with black oat and ryegrass
ABSTRACT: Crop coefficient (Kc) is the ratio between crop evapotranspiration (ETc) and reference evapotranspiration (ETo), representing the phenological effects on crop water consumption. Kc is fundamental to estimating ETc by agrometeorological methods. This research study aimed to determine Kc and ETc values for Guinea grass (Megathyrsus maximus cv. Momba�

4. Wilting whole crop black oat with glyphosate for ensiling: effects on nutritive, fermentative, and aerobic stability characteristics
ABSTRACT We aimed to evaluate the effects of glyphosate as a chemical desiccant on the nutritional quality, fermentation pattern, and aerobic stability of wilted black oat (Avena strigosa Schreb) silage. Black oat sowing occurred in the first fortnight of May 2013. Desiccant application took place when oat reached milky/dough grain stage (96 days after plant

5. EVALUATION OF THE USE OF Acacia mearnsii TANNIFEROUS EXTRACT AS MODULATOR OF RUMINAL FERMENTATION IN CATTLE / AVALIAÇÃO DO USO DE EXTRATO TANÍFERO DE Acacia mearnsii COMO MODULADOR DA FERMENTAÇÃO RUMINAL EM BOVINOS
The effect of levels of Acacia meanrsii tannin extract addition in cattle diet (0, 0.8, 1.6 or 2.4%, dry matter (DM) basis) on rumen fermentation, digestion and N retention was evaluated. The experiment was conducted in a 4 x 4 Latin Square design with four steers (156 33 kg of body weight (BW)) housed in metabolism cages. Diet was 60% oat (Avena strigosa) a

6. DISPONIBILIDADE E TRANSFERÊNCIA DE NITROGÊNIO, FÓSFORO E POTÁSSIO EM UM ARGISSOLO SUBMETIDO À APLICAÇÃO DE FONTES DE NUTRIENTES / AVAILABILITY AND TRANSFER OF NITROGEN, PHOSPHORUS AND POTASSIUM IN SANDY TYPIC HAPLUDALF SOIL SUBMITTED TO THE APPLICATION OF SOURCES OF NUTRIENTS
The swine and cattle activities are of great economic and social importance in Brazil in the southern region, but generate of large volumes of waste, that when applied to the soil can be mineralized and part of the nutrients released can be absorbed by plants or transferred by runoff or percolation. The aimed of this study was to evaluate the rate of mineral

7. ATRIBUTOS DO SOLO E DESEMPENHO DA CULTURA DO MILHO SOB DIFERENTES ALTURAS DE MASSA DE FORRAGEM PÓSPASTEJO / SOIL ATTRIBUTES AND CORN DEVELOPMENT UNDER DIFFERENT HEIGHTS OF FORAGE POST-GRAZING
The Crop-Livestock System (ILP) refers to an association between two activities in the same area at different periods of the year, that involves annual crops and livestock. This study aimed to: (a) evaluate the dry matter yield and residual dry matter remaining of winter intercrop forage (oat, rye and vetch) under different heights of post-grazing residue, (

8. DECOMPOSIÇÃO DE RESÍDUOS CULTURAIS DE PLANTAS DE COBERTURA DE SOLO E EMISSÕES DE ÓXIDO NITROSO / COVER CROPS RESIDUES DECOMPOSITION AND NITROUS OXIDE EMISSIONS
The inclusion of summer cover crops (SCC) in the no-till system is an interesting alternative to promote the addition of elevated quantities of plant biomass and nitrogen (N) to the soil. The C and N dynamics during the SCC residue decomposition can control the nitrous oxide (N2O) fluxes to the atmosphere. This study was carried out to quantify the SCC resid

9. Behavior pattern of beef heifers supplemented with different energy sources on oat and ryegrass pasture
The objective of this study was to evaluate behavior patterns of heifers grazing on black oat (Avena strigosa Schreb.) and ryegrass (Lolium multiflorum Lam.), fed supplementation with brown rice meal and/or protected fat. A total of 28 Charolais × Nellore crossbred heifers at average initial age of 18 months and with initial live weight of 274.9±4.97 kg we

10. Use of conditioning in the production of black and white oat hay using two cutting heights
The study was conducted to estimate the dehydration curves, chemical composition, and occurrence of fungi in white oat hay (Avena sativa L. cv. Guapa BRS) and black oat hay (Avena strigosa Schreb cv. Common) at two cutting heights. Dehydration curves were studied under a randomized block design with a 2 × 2 factorial arrangement using split plots in time, c

11. DINÂMICA DO FÓSFORO NA INTEGRAÇÃO LAVOURA-PECUÁRIA SOB SISTEMA PLANTIO DIRETO / Phosphurus dynamic in crop livestock integration under notillage.
The necessity to preserve the soil, coupled with the constant search for lower production costs and increased productivity resulted in the use no-tillage (NT). Efficient technique in the preservation and use of highly weathered soils (tropical and subtropical soils). However, only the continuous cultivation of monocultures has been implicated in reduced prof

12. TEMPERATURE AND HUMIDITY OF A SANDY LOAM SOIL CULTIVATED WITH MAIZE / TEMPERATURA E UMIDADE DE UM SOLO FRANCO ARENOSO CULTIVADO COM MILHO
Water is a key factor for crop yields, and causes major fluctuations in productivity, especially for maize cultivated in southern Brazil. Mulching the soil surface, temperature and soil moisture are factors closely linked and, when handled properly, can provide the increases crop yields. The soil water conservation is an important aspect for more stable and
