Investigations were carried out in the crop rotation experimental field at the Institute of Horticulture Lithuanian Research Centre for Agriculture and Forestry (IH-LRCAF) in 2016-2017. The aim of investigation -- to estimate the parameters of goatsbeard and black salsify productivity in the flat soil and ridge glance soil surface during different growing year. The object of investigation was the cultivar 'Mammouth Sandwich Island' of goatsbeard (Tragopogon porrifolius L.) (Germany) and two cultivars 'Hoffmann's Schwarze Pfahl' (Germany) and 'Duplex' (Netherlands) of black salsify (Scorzonera hispanica L.). Results of investigation showed that the highest total (18,1 t ha-1) and marketable (14,4 t ha-1) yield of goatsbeard and the highest total (18,9 t ha-1) and marketable (15,2 t ha-1) yield of black salsify was determined in the ridge glanced soil surface. The marketable yield of goatsbeard 4,4 % and 9 % of black salsify was higher in the ridge glance soil surface compared with flat soil. Plants distinguished with the index of root shape compared in the flat soil and ridge glance soil surface. [ABSTRACT FROM AUTHOR]

The productivity of sweet pepper (Capsicum annuum L.subsp. macrocarpum var. grossum (L.) Sendt.) fruits was investigated at the Institute of Horticulture, Lithuanian Research Centre for Agriculture and Forestry in 2015-2016. Plants were grown in unheated polyethylene greenhouses. The object of investigation was eight sweet pepper cultivars and hybrids 'Reda' (Lithuania), 'Alanta' (Lithuania), 'Whitney' H (Netherlands), 'Paradise' H (Czech Republic), 'Stanley' H (Poland), 'Garnet' H (Czech Republic), 'Turbine' H (Netherlands), 'Oreny' H (Czech Republic).

Experiments were carried out in 2016-2017 at the Institute of Horticulture, Lithuanian Research Centre for Agriculture and Forestry. The aim of the research was evaluated the morphological parameters of carrot hybrids 'Jola' root crops, productivity and qualitative parameters. The quantitative and qualitative parameters of the new hybrid were compared to the results of investigation of 'Garduolės' and hybrids 'Svalia BS' and paternal forms. It was established, that the new hybrid variety 'Jola' roots are on average 20.16 cm long and 4.03 cm in diameter, yielding 65.10 tons per ha-1 and accumulates on average 19.42 mg of 100 g-1 carotene, 8.38% total sugar and 11.43% dry soluble solids.

The study was performed at the LRCAF institute of Horticulture in 2015-2017. The aim of this experiment was to evaluate the morphological features of plants and fruits of cucumber (Cucumis sativus L.) cultivars, to select samples with economical features for breeding of constant lines and heteroses hybrids. There were estimated 21varieties and hybrids bred in Lithuania, Netherland, Poland and Russia. Plants were grown in unheated plastic tunnels. According the results of estimation there were selected samples with early blooming by stamens and pistillate flowers, distinct by plants height and shape, intensity of lateral stems growing, different fruits shape and taste. Cucumber varieties 'Krepysh', 'Liubimchik', 'Maliutka', 'Malysh' maybe used as donors of selection material for early fruiting cucumbers. Hybrids and varieties 'Akord', 'Altaj', 'Anulka', 'Atomic', 'Krepysh', 'Orfeus' are valuable for breeding of outdoor cucumbers. [ABSTRACT FROM AUTHOR]

Investigations of productivity of the most popular edible onion (Allium cepa L.) cultivars grown in Lithuania were carried out in the experimental field of the Institute of Horticulture, Lithuanian Research Centre for Agriculture and Forestry (IH-LRCAF) in 2008-2010. Three onion cultivars - 'Babtu didieji', 'Red Baron' No. 080 and ten hybrids - 'Spirit' F1, 'Burgos' F1, 'Mission' F1, 'Napaleon' F1, 'Vision' F1, 'Solution' F1, 'Sunskin' F1, 'Musica' F1, 'Stamford' F1 and 'Red Beauty' F1 were estimated. The yield and its structure were evaluated. The height and diameter of onion bulbs were determined. The index of bulb shape was calculated. The obtained results showed that our climatic conditions are favourable for onion growing. All investigated edible onion cultivars and hybrids differed according to their productivity. Hybrid 'Musica' F1 was distinguished for the significantly highest total and marketable yield during the period of three year investigation. The highest output of the marketable yield was determined with 'Vision' F1. The largest bulb size was obtained from 'Stamford' F1. The obtained results confirm that a genotype is an important factor that affects crop productivity. Lietuvos agrarinių ir miškų mokslų centro filialo Sodininkystės ir daržininkystės instituto eksperimentiniame lauke 2008-2010 metais tirtas Lietuvoje populiariausių valgomojo svogūno (Allium cepa L.) veislių ir hibridų produktyvumas. Vertintos trys valgomojo svogūno veislės: 'Babtų didieji', 'Red Baron', Nr. 080, ir dešimt heterozinių hibridų: 'Spirit' F1, 'Burgos' F1, 'Mission' F1, 'Napaleon' F1, 'Vision' F1, 'Solution' F1, 'Sunskin' F1, 'Musica' F1, 'Stamford' F1, 'Red Beauty' F1. Nustatytas derlius ir jo struktūra. Įvertintas ropelių aukštis ir skersmuo. Apskaičiuotas ropelės formos indeksas. Gauti rezultatai parodė, kad mūsų klimato sąlygos yra palankios svogūnams augti. Visų tirtų veislių ir hibridų produktyvumas buvo skirtingas. Trejų metų tyrimo duomenys parodė, kad iš esmės didžiausią bendrą ir prekinį derlių išaugino hibridas 'Musica' F1. Didžiausia buvo 'Vision' F1 svogūnų prekinio ropelių derliaus išeiga. Didžiausio svorio ropeles išaugino 'Stamford' F1. Gauti rezultatai patvirtina prielaidą, kad genotipas yra svarbus augalų produktyvumo veiksnys. [ABSTRACT FROM AUTHOR]
