Core Ideas Miscanthus and switchgrass are often touted as biomass crop choices, but have rarely been compared side‐by‐side. was slower to establish than cultivars, out‐yielded in the latter 3 yr of trial. Phosphorus soil nutrient most likely be drawn down levels requiring fertilization, after N. Comparative performance tests perennial grasses for yield, quality, removal needed guide decisions toward meeting European Union targets renewable energy production. We hybrid miscanthus ( ×...

This study evaluates the effect on ‘Splendor’ and ‘Primoris’ strawberry cultivars of different dates inoculation with Glomus intraradices, an arbuscular mycorrhizal (AM) fungus. Additionally, plants were grown in a soilless growing system or without Bacillus velezensis at beginning experiment. A completely randomized block design (2 biofertilizer treatments × 2 3 dates) replications was used. Each replicate consisted one bag 10 plants. Fruit weight, fruit quality, growth parameters, SPAD...

The relationships between climatic variables, soil parameters, tree nutrition and site index (SI) were examined in 30 chestnut coppice stands Asturias, the region with largest area of north-west Spain. SI was estimated from a top height projection equation for this species. A sample obtained at 0- to 20-cm depth several leaves collected upper zone dominant trees each plot further analysis. Chi-square automatic interaction detection parametric regression techniques used determine key factors...

Colonial bentgrass (Agrostis capillaris L.) is a potential source for genetic improvement of resistance to environmental stress and disease other species spp.). To conserve study the existing resources colonial use in breeding, diversity was investigated using amplified fragment length polymorphism (AFLP) markers. Included this were 22 accessions from US Department Agriculture germplasm collected 11 countries, conjunction with 14 northern Spain 3 commercial cultivars. Ten EcoRI–MseI 6...

White clover (Trifolium repens L.) is an essential element of sustainable livestock systems in temperate climates because its adaptability to a range management and soil fertility conditions. The performance 15 accessions white collected northern Spain, two cultivars, the medium-leaved Huia large-leaved California, grown as spaced plants Galicia, sward plots Asturias was compared over period years. data obtained were reduced principal components that cumulatively explained 92.4% total...

Fifteen accessions of Festuca group rubra collected in northern Spain were characterized and grouped into four taxa on the basis leaf anatomy, morphology ploidy; seven identified as F. heteromalla; two trichophylla ssp. asperifolia; nigrescens microphylla pruinosa. All one commercial cultivar ‘Wilma’ (F. nigrescens), used control, established at Mabegondo Agronomical Research Centre, A Coruña (Galicia) a completely randomised block design with three replicates 10 plants per accession. The...

RESUMEN El selenio (Se) es un elemento traza esencial no solo para animales, plantas y microorganismos, sino también la salud de las personas. Por ello, parece que aumentar cantidades en puede tener implicaciones positivas. objetivo este trabajo fue determinar sistema cultivo sin suelo con fibra coco el efecto del selenito (Se IV) selenato VI) peso, calidad frutas fresa, así como variables crecimiento contenido clorofilas hojas jóvenes adultas planta fresa variedad ‘Splendor’.

Cider production requires detailed knowledge of the apple varieties used. Of hundreds cider and dessert apples in Spain, only a few are accepted for producing under “Sidra de Asturias” protected designation origin. The visual characteristics many these very similar, experts can distinguish them. In this study, an artificial intelligence system using Transfer Learning techniques was developed classifying some Asturian varieties. performance several convolutional neural network architectures...

Fifty-six half-sib families of perennial ryegrass ( Lolium perenne ), derived from wild populations in Galicia, were examined for the presence endophytes; 28 endophyte-infected (E+) and endophyte-free (E−). All established spaced-plant nurseries trial plots at two locations 1992. E+ had a significantly P <0·05) higher first cut, spring total yield than E− one location third year after planting. At this location, water deficit was about 75% other all three years study. Endophyte did not...

The edaphic factors have been evaluated in a sloping segment of 2,68 ha the «Tuña» woodland municipality Tineo, affected for descending controlled burns Erica and Ulex with yield 1,5 h-1. soil alterations, immediately after to 7, 30 90 day, took place 0-2, 2-5 5-10 cm depth, showing existence temporary increment fertility (increase C, N, K, Ca, Mg specially available P). Immediately fire, clay fraction diminished sand it increased vice versa days burns. increase fire could be taken advantage...

Aim of study: Germination assays are vital in the management material preserved germplasm banks. The rules published by International Seed Testing Association (ISTA) generally those followed such assays. In wild species, seed dormancy and inter-population variability increase difficulty estimating viability. aim present work was to determine germination requirements seeds from different populations pasture grasses species.Area Northwestern SpainMaterial methods: Seeds eight species Festuca,...

Dry matter yield, persistence and three parameters of nutritive value were determined in two perennial ryegrass (Lolium perenne L.) genotypes either infected with a lolitrem B-free fungal endophyte or not infected, over fouryear period at different locations north-west Spain. The did influence the productivity four years study. Insufficiently stressful conditions could explain these results. plants was influenced by infection, except for organic digestibility water-soluble carbohydrates on...

Planting grasses that require low maintenance is a good option for reducing the management input required. The objective of this study was to obtain information about turfgrass characteristics based on spaced-plant characterization and turf performance in plots two selections (Paula hard fescue Casero colonial bentgrass) recently released public distribution by Plant Production Area University Oviedo. plants were grown under conditions no irrigation, fertilizer, pesticide application minimal...

Aim of study: To evaluate agronomic performance and changes on soil chemical properties in two types managements: conventional or sustainable.Area Principality Asturias, Spain.Material methods: On a sandy-clay-loam texture soil, three winter forage legumes (faba bean, red clover white lupin), monoculture mixed with Italian ryegrass organic fertilization (sustainable management) versus inorganic (conventional were evaluated during consecutive years. After the harvest spring, rotations...
