Pozycja Open Access Analiza obrazu występowania mątwika ziemniaczanego (heterodera rostochiensis woll.) w województwie szczecińskim(1964) Kisiel, M.; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Fitopatologii i Ochrony RoślinThe Heterodera Rostochiensis Woll, is considered the most dangerous potato vermin. In the existent conditions in the Szczecin region the mentioned vermin may become a check to potato exports and to home marketing of seedlings as well. Investigations have shown that the vermin occurs everywhere in the Szczecin region with varied intensity. Most contaminated appear the northern and western districts. It was found that up to the year 1962 4237 farms (with 167 state) farms in the number) were contaminated on an area of 1407 ha. The proportion of contaminated area to the whole potato area made an average of 1,8 %.Pozycja Open Access Badania nad owadami zapylającymi lucernę(1964) Honczarenkowa, J.; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Ochrony RoślinFor the purpose of increasing the yield of lucerne seed, researches on pollinating insects have been undertaken. After two years of study (being now continued) it was found that pollination of lucerne flowers is mainly due to single hymenoptera and bumblebees, especially of the following varieties: Bombus Hortorum L., Bombus Lapidarius L. and Bombus agrorum P. Ordinary bees, though often crowding around lucerne plants, play a minor part in their pollination.Pozycja Open Access Badanie zachwaszczenia pola doświadczalnego Katedry Ogólnej Uprawy Roli i Roślin w R.Z.D. Lipki w latach 1961-1963(1964) Hoffman-Kąkolowa, I.; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Ogólnej Uprawy Roli i RoślinDuring a period of 3 years, observations in flora tables conducted before and after planting registered 59 weed varieties. The number of specimens per 1 m² varied from 1700 to only a few, with the predominance of yearly spring and winter varieties. The spread of weeds was due to after-cultivations and an enormous number of seeds in the soil. In the soil samples taken for testing, seeds of 51 weed varieties were found, and in 1 m² of arable soil, there were 99,500 to 267,000 seeds.Pozycja Open Access Doświadczenia nad działaniem niektórych preparatów chemicznych w walce z drutowcami(1964) Honczarenkowa, J.; Kisiel, M.; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Ochrony Roślin; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Ochrony RoślinThis study aimed at testing and comparing two preparations of the sodium carbohydrate group, the powder "Gamatox" (Owadziak 1,2') and the imported Aldrin in fighting the wireworm. In order to protect potatoes and maize, two years of field and laboratory experiments have been undertaken. The mentioned preparations were either sown into the ground stripewise or used to treat the seedlings and grain. Either preparation produced strong toxic effects on the wireworm, but "Gamatox" acted with more speed and greater power. Aldrin, on the other hand, kept on being toxic till a later time. Stripe sowing into the ground proved more advantageous for the plants than treating the grain or seedlings, the latter way being sometimes detrimental to the germination of the plant seeds.Pozycja Open Access Prototyp gradomierza rejestrującego(1964) Koźmiński, C.; Bac, S.; Wyższa Szkoła Rolnicza w Szczecinie. Katedra MeteorologiiEmployment of hydrostatic weighing methods enabled the authors to produce a registering hail meter with a measuring surface of 800 cm². A 1000 g increase of hr11 granules weight causes a perpendicular move of the hand (feather) by 200 mm. The prototype enables to read hail intensity with an accuracy of 10 g per 30 seconds as well as to tell the number of rainfalls from the particular hail storm.Pozycja Open Access Wpływ niektórych czynników na kiełkowanie nasion Erobium cicutarium(1964) Hoffman-Kąkolowa, I.; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Ogólnej Uprawy Roli i RoślinThe Erodium cicutarium seeds show very low germination power, increasing as the time of resting goes by. Experiments bring evidence that weak germination power is due to the fact that the seed cover becomes gas- and water-tight by undefined chemical compounds soluble in ethyl alcohol but nonsoluble in water. There has also been noted that some other substances inhibit germination in the Erodium cicutarium seeds.Pozycja Open Access Wpływ różnych terminów podsiewu motylkowych na plony łąki torfowej(1964) Maślankowska, L.; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Uprawy Łąk i PastwiskThis study presents results obtained from sowing of papilionaceous plants on existent meadows considered to be one of the means for increasing papilionaceous contents in the plant cover. Sowing and NPK manuring done on harrowed turf of peaty mineral grassland in three terms: 25.IV., 25.V. and 25.VI. only slightly increased the yield (4-5% hay) in comparison with pure NPK but raised the papilionaceous contents in the plant cover; the more so the earlier sowing they were undersown.Pozycja Open Access Wpływ wałowania na plonowanie, roślinność i właściwości fizyczne gleby łąkowej(1964) Honczarenko, G.; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Uprawy Łąk i PastwiskProlonged exploitation use causes in peat soil a tendency to loosen and pulverize its top peat layer. Rolling of peat grassland moderately moistured, produces conducive effects on cropping, vegetation and levelling of the meadow surface, but rolling of wet or muddy grassland (insufficiently dried or after rainfall) does rather harm to the physical properties of the soil and produces a mass appearance of tussock grass and common rush.Pozycja Open Access Wpływ wysokości koszenia na plonowanie, roślinność oraz zadarnienie łąk(1964) Honczarenko, G.; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Uprawy Łąk i PastwiskThe height of mowing influences considerably cropping and vegetation of grassland. Most adequate proves a mowing height of 5-6 cm, but very often the mowing height on grassland is indeed much bigger and thus great losses are brought about. The biggest losses occur by low plant cover of the second cut and amount to 50% of the biologic yield. Higher mowing causes growth of high grass, while lower mowing increases the amount of low loose hassock grass which produces better meadow sodding.Pozycja Open Access Występowanie larw Elateridae (Col.) na łąkach i polach w okolicy Jeziora Dąbskiego(1964) Honczarenkowa, J.; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Ochrony RoślinThree years of investigations on soil entomofauna carried out on 5 types of grassland and fields, close to the Dąbskie Lake, have shown that the vermin Elateridae (wireworm) larvae constitute 40% of the entomofauna. There were 13 varieties, most of which covered many-years-old grassland and barren lands, settling mainly in the top layers. The Corymbites sjaelandicus Mull variety is grouped in great numbers, but mainly on grassland, while the Corymbites aeneus L. settled rather in fields. The Agriotes sp. groups are in great numbers represented both on grassland and fields, whence they probably spread to neighboring areas.Pozycja Open Access Zagadnienie rejonizacji niektórych upraw roślinnych na terenie Pomorza Zachodniego w świetle częstości występowania szkodliwych elementów meteorologicznych(1964) Prawdzic, K.; Koźmiński, C.; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Meteorologii; Wyższa Szkoła Rolnicza w Szczecinie. Katedra MeteorologiiAn Attempt is here made to fix areas in West Pomerania where a number of meteorologic phenomena occur (as observed in the years 1948-1959 by 18 meteorologic PIHM stations) that may really do harm to principal farm crops. The mentioned phenomena include slight frosts, droughts, excessive rainfalls, hail and stormy winds. Most interesting prove the results obtained on potatoes being subject to great harm done by meteorologic factors when planted on peat soil in valleys, particularly in North-East Pomerania. The risk, then, of planting them in such valleys is much greater than when planted on the neighboring highlands.Pozycja Open Access Zwalczanie situ rozpierzchłego za pomocą dikoniertu oraz nikeponu(1964) Maślankowska, L.; Łyduch, Ł.; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Uprawy Łąk i Pastwisk; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Uprawy Łąk i PastwiskThe study presents results of researches on fighting common rush with Dikoniert and Nikepon applied to produce better moisturing of the sprinkled plants. It has been shown that Dikoniert destroys common rush quite completely when applied to double spraying at a rate of 5 kg/ha with an addition of 0.45 kg/ha Nikepon to each spray. Susceptibility has been noted by the Lotus Uliginosus, by the common sedge, and, of the weeds, by the horsetails: field and toadpipe and by the cornthistle.
