1. May the crossing between diploid and tetraploid Italian ryegrass transfer glyphosate resistance to the next generation?
ABSTRACT Italian ryegrass (Lolium multiflorum Lam.) is a grass weed found in winter cereals, with several glyphosate-resistant diploid populations. Furthermore, the use of Italian ryegrass tetraploid genotypes creates an opportunity to increase the forage demand in replacement of diploid populations. The aim of this research was to evaluate the crossing capa

2. Apparent selectivity of sheep in deferred marandu palisadegrass pastures with variable initial heights
RESUMO Objetivou-se avaliar a seletividade aparente de ovinos em pastos de capim-marandu (Urochloa brizantha cv. Marandu) com quatro alturas no início do diferimento (15, 25, 35 e 45cm). O período de diferimento foi de 92 dias e iniciou em 21/03/2014. As avaliações ocorreram no início (primeira semana), meio (45° dia) e fim (92° dia) do período de pa

3. Soil physical properties and soybean productivity in succession to cover crops
ABSTRACT The objective of this research was to assess soybean productivity in succession to cover crops grown during the winter, in addition to assessing physical properties macroporosity (Ma), microporosity (Mi), total porosity (Pt), soil density (Sd) and aggregate stability by means of the following variables: aggregate stability index, geometric mean diam

4. 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�

5. VEGETATIVE DEVELOPMENT AND GROWING DEGREE-DAYS OF TROPICAL AND WINTER FORAGES
ABSTRACT One of the limitations to producing irrigated forages is setting suitable biometric parameters to establish the entrance of animals to grazing areas. Such parameters can be measured or even estimated. Estimates are advantageous for being practical and able to be used for grazing optimization. This study aimed to evaluate the correlation among growin

6. Response of elephant grass to grazing under an organic production system
RESUMO O objetivo desta pesquisa foi avaliar o capim elefante nos sistemas orgânico e convencional. No sistema orgânico, combinaram-se espécies com períodos de crescimento complementares; o capim elefante foi plantado em linhas com 3,0 m de distância entrelinhas; entre as fileiras de capim elefante, durante o período hibernal, foi semeando o azevém e

7. Protein and carbohydrate fractionation of Jiggs Bermudagrass in different seasons and under intermittent grazing by Holstein cows
ABSTRACT. Jiggs bermudagrass has presented competitive production potential over other forages. However, there is a lack of information about the nutritional value of this forage with important relevance in ruminant nutrition. This study aimed to evaluate the protein and carbohydrate fractionation of Jiggs bermudagrass in different seasons of the year under

8. TRACTIVE DEMAND, SOIL MOBILIZATION PARAMETERS, AND CORN YIELD IN COMPACTED OXISOL
ABSTRACT Direct seeding systems are characterized by soil disturbance only occurring in the sowing line and the maintenance of the remaining area is achieved by covering with crop residues. Without total area soil mobilization as recommended by the no-tillage system, associated with the increase in the degree of soil compaction caused by the traffic of agric

9. Protein and carbohydrates fractionation in Paiaguas palisadegrass intercropped with grain sorghum in pasture recovery
ABSTRACT. Paiaguas palisadegrass was released in order to meet the requirements of the different production systems. However, little is known about the quality of the forage. The goal of this study was to evaluate the protein and carbohydrate fractionation of the Paiaguas palisadegrass after intercropping with grain sorghum in the pasture recovery, through t

10. NDVI and meteorological data as indicators of the Pampa biome natural grasslands growth
ABSTRACT The present study aimed to characterize the dynamics of NDVI and meteorological conditions, relating both to the annual dynamics of biomass accumulation in natural pastures of the Pampa biome as a way of subsidizing growth modeling. Forage accumulation rate data from a long-term experiment, NDVI data from the MODIS images, and meteorological data me

11. Cover crop rotations in no-till system: short-term CO2 emissions and soybean yield
ABSTRACT: In addition to improving sustainability in cropping systems, the use of a spring and winter crop rotation system may be a viable option for mitigating soil CO2 emissions (ECO2). This study aimed to determine short-term ECO2 as affected by crop rotations and soil management over one soybean cycle in two no-till experiments, and to assess the soybean

12. Intraspecific tetraploid hybrids of Paspalum notatum: agronomic evaluation of segregating progeny
ABSTRACT: For many decades, animal production in southern Brazil has been based on native forage grasses. Paspalum notatum Flügge (bahiagrass) is one of the most frequently used native grass in southern Brazil. The native germplasm of P. notatum is tetraploid and displays apomictic reproduction; hence, chromosome doubling of sexual diploid accessions is req
