This work presents the impact of climate change on full flowering (BBCH 65) in Norway spruce [ Picea abies (L.) Karst.] at 54 phenological stations over two 30-year-long periods, from 1961 to 1990 and 1991 2020. The were located 10 protected areas (protected landscape area, national park) elevations 390 1,400 m a.s.l. We analyzed changes average onset flowering, trends phase, altitudinal gradie...

The effect of three fungicide treatment programmes and the level spring nitrogen fertilisation on seed yield two types ofcultivars Brassica napus L. sown at different seeding rates was studied in a field experiment. subject study anopen-pollinated cultivar ‘Casoar’ restored hybrid ‘Visby’. Three plant protection programmes, levels nitrogenfertilisation (160 220 kg N⋅ha1), for each (‘Visby’—50 7...

Se utilizó un diseño experimental bloque completo randomizado arreglo factorial. En germinador cada unidad conformada por dos surcos 25 semillas surco. almacigo consto 16 m...

The use of biostimulants in crop production can be an economically viable option for farmers and enable them to meet the increasing quality standards agricultural products consumer expectations sustainability environmental protection. aim this study was determine effect foliar application on course physiological processes pea (Pisum sativum L.) plants. Field studies with conventional fertilizer...

The study presents the results of a three year field trial aimed at assessing nutritional status maize in critical growth stages by means plant analysis cultivation cultivars differing their agronomic and genetic profile. main research problem was to demonstrate whether availability nitrogen from stabilized fertilizers for “stay-green” varieties is consistent with dynamics demand this component...

BACKGROUND Leaf wall area (LWA) has been proposed as an appropriate dose expression for field testing of plant protection products (PPPs) applied via foliar spray in trellised grapes. However, its efficiency could change depending on the characteristics crop or pesticide application equipment (PAE). Herein, three technologies were evaluated. A traditional air-assisted tractor-mounted sprayer wa...

To protect the environment and reduce impact of fertilizing on climate change, a tailored fertilization according to needs plants becomes more important. In organic farming, main sources nitrogen (N) are fertilizers, such as compost farmyard manure. conventional agricultural systems, various plant sensors have already proven that they can guide efficient fertilization. Since these record growth...

The development of new and implementation existing methods field assessment winter wheat genotypes is one the key tasks modern breeding. use screening in breeding allows breeder to get a more objective assessment, as well increase volume studied samples several times. time spring vegetation recovery (TSVR) stages period wheat. Biometric spectral with onset TSVR establishing how plants certain g...

Abstract Hemp ( Cannabis sativa L.) is one of the traditional crops currently being newly re-introduced in Slovakia and cultivated for multi-purpose uses, while still there a lack crop biomass yield data. The main objective paper to document aboveground selected cultivars hemp ('Bialobrzeskie', 'Felina', 'Santhica', 'Epsilon', 'Futura'), which were tested pilot open-field experiments conducted ...

Reliable phenological observations are needed to quantify the impact of climate change on tree phenology. Ground remain a prime source data, but their accuracy and precision have not been systematically quantified. The high subjectivity ground affects accuracy, within-population variability phenology precision. magnitude those effects is unknown date. We first explored inter-observer in timing ...
