Didžiausia žygių genčių įvairovė buvo dirbamoje žemėje po pievos (14 genčių), mažiausia - natūralioje pievoje (11 genčių). Nustatytos eudominantinės gentys Pterostkhus ir Harpalus aktyviausios buvo dirbamose agrocenozėse: intensyviai dirbamoje žemėje ir dirbamoje žemėje po pievos. Recedentinių genčių gausa didžiausia buvo dirbamoje žemėje po pievos (3 gentys), o intensyviai dirbamoje žemėje jų visai nebuvoDuring the study 13,283 ground beetles were collected. Ground beetles belonged to 15 genera and 42 species. The largest genera variety was denned in the arable land established after meadow (14 genera), the lowest - in the natural grassland (11 genera). Eudominant genera Pterostichus and Harpalus were active in such agrocenoses: intensively cultivated arable land and arable land established after meadow. Recedent genera were determined as most abundant in the arable land established after meadow (3 genera) and ...

Austria was started at the Institute of Horticulture in 2007. These studies were conducted in the project ‘Establishment of warning models of horticultural plant diseases and pests and its implementation in Lithuania using warning equipment‘. One of the goals of this project was to investigate the Alternaria forecasting model for carrot in Lithuanian conditions. Research on the efficiency the Alternaria forecasting model for carrot under Lithuanian conditions was carried out in 2007–2008. According of meteostation‘s iMETOS®sm the Alternaria forecasting model data favorable conditions for Alternaria leaf blight infections formed in June, July and August, and it generated due to certain weather conditions. Compared with untreated (not sprayed) carrots, spraying according to the Alternaria forecasting model intensity of disease inhibited averaged 91.73%, spraying according to conventional system – 76.26% in carrot ‘Samson‘. The Alternaria forecasting model for carrot was investigated for the first time; therefore for final validation of this model under Lithuanian conditions the experiments should be continuedVytauto Didžiojo universitetasŽemės ūkio akademij

However, to obtain production with high quality has become a challenge as the application of chemicals has been severely restricted. Therefore, various alternatives of biological origin products are constantly being sought. The objective of the study was to test the effect of five different microbiological preparations on the growth and development of beans grown under organic farming conditions. The experiment was performed in 2018 in the fields of agricultural association Auga, Raseiniai district municipality, Kalnujai village surroundings. The effect of five different microbiological products on bean growth and plant biometric parameters was investigated. Bean seed was coated with microbiological products. The growth of plants was observed once a week. Compared to the control, all five microbiological preparations had a positive effect on bean growth and development. However, the best results were defined in beans treated with a product contained complex of zinc-releasing bacteria (Bacillus coagulans, Bacillus subtilis, Bacillus polymyxa)Agronomijos fakultetasVytauto Didžiojo universiteta

The product is exclusive due to its active ingredient azadirachtin A which is derived on botanical background, Also it is listed for use even in certified organic production. The product registered mainly for protection of greenhouse crops against thrips, aphids, whitefly, spider mites. Neemazal T/S 1%e.c. in the trial was applied for protection seedlings of widely grown ornamental plant common China-aster (Callistephus chinensis (L.)) against onion thrips (Thrips tabaci (Lind.)). Three different concentrations of the spraying solution were applied (0,5%, 0,3% and 1%). The calculation of the pests accomplished before application and repeated 7 days after treatment. The efficiency of Neemazal T/S 1%e.c. for protection of common China-aster seedlings against onion thrips was compared with efficiency of systemic insecticide Actara 25%w.g.

It was established that comparing with the control, the abundance of the pest had been substantially reduced by applying both insecticide Vertimec 018 EC alone and its mixtures with bio-product Konflic. However, the best results had been obtained by treatment of mixtures Vertimec 018 EC 0.12% + Konflic 0.2% and Vertimec 018 EC 0.12% + Konflic 0.3%. The average biological efficiency of 79.9 to 96.5% was reached. The application of bio-product Konflic increased the effect of the insecticide Vertimec 018 EC.

The quality of cereal grains also is affected by the soil. The quality of winter wheat grains is determined by moisture, protein content, sedimentation rate, wet gluten content and its quality, falling number, hectolitre weight, total impurity content, grain and garbage impurities, etc. The experiment was carried out in 2015-2016 at the Experimental Station of Aleksandras Stulginskis University. The soil was identified as (Calc(ar)i-Epihypogleyic Luvisols). The aim of the study was to compare the quality parameters (protein content, wet gluten content, sedimentation values, starch content, falling number) of different varieties winter wheat grains (‘Artist‘, ‘Edvin‘, ‘Skagen‘, ‘Viola‘ and ‘Bertold’). The grain quality was determined by accepted standard methods. Results of the research. Winter wheat varieties ‘Viola‘ and ‘Bertold’ were distinguished by the highest protein content, wet gluten content and the highest sedimentation values. A high correlation (r = 0.960*) was found between protein content and wet gluten content, while a mean negative correlation (r = -0.800*) was determined between wet gluten and starch content. Significantly highest falling number (391.3 s.) was recorded in grains of the late winter wheat variety ‘Skagen’. The enzyme α-amylase was the most active in grains of the early-growing varieties ‘Edvin’ and ‘Viola’, where the falling number was found essentially the lowest (155 s and 187.7 s respectively)Vytauto Didžiojo universitetasŽemės ūkio akademij

Five pitfall traps were set out in each of agrocenosis and the traps were active from May 28th till August 15th. The traps were checked every two weeks. In the course of the study, a total of 98 adult specimens of click beetles were caught, belonging to eight species: Actinecerus sjaelandicus Mull., Agriotes lineatus L., Agriotes obscurus L., Agriotes sputator L., Agrypnus murinus L., Athous haemorrhoidalis Fabr., Hemicrepidius niger Hbst. and Oedostethus quadripustulatus F. Most of the specimens were caught by the traps in the reclaimed pasture and the smallest number of beetles was found in agrocenosis of I-II year perennial grass. Agriotes obscurus was found in all the studied agrocenoses. Actenicerus sjaelandicus and Athous haemorrhoidalis were detected only in natural meadow and were not found in any other studied agrocenosis. The activity of adult click beetles was determined to reach its peak in June – July period. The largest number of the beetles caught in the studied agrocenoses belonged to the species Agriotes obscurus and the rarest were Athous haemorrhoidalis representatives. The eudominants of all of the caught adult click beetles consisted of the following two species: Agriotes obscurus and Oedestethus quadripustulatus. The number of the adult click beetles caught in the pitfall traps decreased as the intensity of land tillage varied. Therefore, a conclusion can be drawn that the abundance of click beetles in agrocenoses is influenced by an intensity of land tillageLietuvos agrarinių ir miškų mokslų centro filialas Sodininkystės ir daržininkystės institutasVytauto Didžiojo universitetasŽemės ūkio akademij
