Boron nutrition and yield of alfalfa cultivar crioula in relation to boron supply Scientia Agricola
Santos,Anacleto Ranulfo dos; Mattos,Waldssimiler Teixeira de; Almeida,Ana Aparecida da Silva; Monteiro,Francisco Antonio; Corrêa,Beatriz Dias; Gupta,Umesh C..
Alfalfa cultivar Crioula (Medicago sativa cv. Crioula) is grown in South Brazil and only a few studies on the plants' boron requirement are available. A greenhouse experiment was carried out with alfalfa to measure boron acquisition, production and distribution in the plant; data on critical level and production potentials were recorded. Plants were grown in ground quartz added with 1 L of solution, with the following boron rates: 0, 0.0625, 0.125, 0.25, 0.50, 1.00, and 2.00 mg L-1. Plants were harvested at 46 days of growth. Forage dry mass was increased by boron supply and dry matter accumulation was considerably low in control. Boron concentration in the leaves was higher than in the stems or roots. Boron utilization from the external solution reached...

Evaluation of the Effect of Some Biopesticides on Alfalfa Weevil Larva, Hypera postica (Gyllenhal.) in Laboratory and Field Conditions CIGR Journal
Alizadeh, Esmaeil.
Alfalfa weevil (Hypera postica Gyllenhal.) control is traditionally based on the use of chemical insecticides. Due to the side effects of these compounds, there are many motivations for the use of integrated control methods, which may include the use of biopesticides (microbial and botanical). The result of the effect of seven doses  of the tested biopesticides (500, 1000, 1500, 2000, 2500, 3000 and 3500 ppm) under laboratory conditions indicated that the insecticides Azadiractin® (1859.971 ppm) and Biobit® (2000.57 ppm) were of the highest, while Basiokara® (3178.697 ppm) and Naturalis® (2973.246 ppm) were of the lowest lethality. Field experiments were carried out based on randomized complete block design with 10 treatments and 4 replications. The...

Intake and digestibility of concentrate and legume hay diets fed to foals R. Bras. Zootec.
Silva,Vinicius Pimentel; Rezende,Adalgiza Souza Carneiro de; Saliba,Eloisa de Oliveira Simões; Costa,Maria Lindomárcia Leonardo da; Lima,Julia Timponi de Moura; Pereira,Renata Vitarele Gimenes.
This study was carried out to evaluate intake, nutrient digestibility and body weight gain of foals on diets of concentrate and legume hay. Treatments were: lucerne hay (Medicago sativa), Campo Grande stylo hay (20% Stylosanthes macrocephala and 80% Stylosanthes capitata) and Mineirão stylo hay (Stylosanthes guianensis cv. Mineirão). Fifteen weaned foals at 160 Kg body weight (BW) were used. The experiment was entirely randomized with three treatments and five replicates. Dry matter intake was estimated at 30 g of dry matter (DM)/kg BW and was comprised of 40% concentrate meal and 60% hay. Fecal production and nutrient digestibility were calculated by the LIPE® marker methodology. There was no difference between Lucerne hay and Campo Grande stylo hay...

Relative Aerial Biomass Yield of Intercroped Alfalfa with Winter Forage Cereals Chilean J. Agric. Res.
Pereyra,Telmo; Pagliaricci,Héctor; Ohanian,Alfredo.
In the tropical regions of the world, intercropping is mostly associated with food grain production, whereas it is receiving increased attention in temperate regions as a means of efficient forage production. The aim of this work was to determine the relative yield of aerial biomass in alfalfa or lucerne (Medicago sativa L.) and winter forage cereals intercrops. These were done in eight systems resulting from the combination of species sown at different dates. The biomass was measured in three situations: alfalfa and cereal sole-crop and alfalfa-cereal intercrops, the relative biomass yields were calculated by the relative yield index (RYI). The field experiment was conducted as a bifactorial array in a randomized complete block design of two replicates....

Selection of alfalfa genotypes for resistance to the foliar pathogen Curvularia geniculata Anais da ABC (AABC)
ÁVILA,MARIANA R.; DALL’AGNOL,MIGUEL; MARTINELLI,JOSÉ A.; SILVA,GERARDA B.P. DA; BREMM,CAROLINA; NUNES,TAMYRIS.
ABSTRACT Foliar diseases impose severe restrictions on the persistence and productivity of Medicago sativa, both of which may be increased by developing disease resistant and more competitive genotypes that can improve pasture quality. We found Curvularia geniculata as the principal alfalfa foliar pathogen in the Brazilian state of Rio Grande do Sul (RS). Growth chamber experiments evaluated the resistance of alfalfa genotypes ‘E1C4’, ‘CPPSul’, ‘ABT 805’ and ‘CUF-101’ to C. geniculata as compared the control ‘Crioula’ genotype. These genotypes were also evaluated in field trials at a sea level site in Eldorado do Sul in central RS and at two sites £200 m above sea level, one in Bagé municipality in south west RS and the other at a farm near the town of...
