Pozycja Open Access Badania nad określeniem energii i siły kiełkowania nasion wyki kosmatej (Vicia villosa Roth).(1964) Mackiewicz, Z.; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Szczegółowej Uprawy RoślinInvestigations carried out in the years 1959-1960 on germination of villous vetch seeds (Vicia villosa Roth) indicate that fresh seeds of the vetch require germination at variable temperature or the temperature of 10-15°C. The 20°C temperature recommended by the qualification rules results in weaker germinative power and energy. The obtained results indicate the necessary change in the qualification rules for villous vetch.Pozycja Open Access Defoliacja nasiennego łubinu żółtego.(1964) Mackiewicz, Z.; Balcerek, W.; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Szczegółowej Uprawy Roślin; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Szczegółowej Uprawy RoślinResearches carried out in the years 1962 and 1963 proved that the defoliation of seed yellow lupine is very important in wet years. Spraying the seed plantations of lupine with chemical burning preparations, applied during pod browning on the main stalk, shortens considerably the ripening period of plants without detrimental effect on yields and germination of seeds. Good results were obtained applying 5 kg of Krezamon, the Polish preparation, in 500 liters of water per hectare or 500 liters/ha of 2% caustic soda.Pozycja Open Access Porównanie działania mieszanek wieloletnich i jednorocznych na wzrost niektórych wskaźników żyzności gleby(1964) Laskowski, S.; Żurański, S.; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Ogólnej Uprawy Roli i Roślin; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Ogólnej Uprawy Roli i RoślinField experiments carried out on light podsol soil in R.Z.D. Lipki WSR Szczecin and R.R.Z.D. in Barzkowice in the years 1960-1962 proved that: Best crops are produced in showery years by a mixture of red clover with English rye-grass and in dry years by a mixture of common birds foot trefoil with English rye-grass. These mixtures differ significantly from the others by producing a rise in the fertility indices (humus, nitrogen, CaC). Winter after-cultures cause half as much rise in the amount of organic compounds in the soil as the soil-structure-creative mixtures.Pozycja Open Access Porównywanie zmianowań stosowanych na glebach lekkich.(1964) Laskowski, S.; Dzienia, S.; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Ogólnej Uprawy Roli i Roślin; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Ogólnej Uprawy Roli i RoślinThe field experiments that for a period of 3 years (1960-1963) had been carried out on weak limed complete sands in R.Z.D. Lipki allow the following preliminary conclusion: 1. A direct plantation of ear (spiky) plants after ear plants successively for three or even for two years causes a fall in the yield in of the crop rotation. 2. The best rotation link appears to be: a) maize-spring wheat + kct-kct; medium b) maize-spring wheat-green field pea Worse: c) maize-spring wheat-seed field pea Worst: d) maize-green field pea-summer swede-like rape. 3. On weak soil, cultivation of field pea for fodder is economically more effective than maize for green forage.Pozycja Open Access Rozwój wyki siewnej w siewach mieszanych na zieloną paszę w plonie głównym, wtórnym i poplonach ścierniskowych.(1964) Pawlus, M.; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Szczegółowej Uprawy RoślinThe results of the experiments carried out in the years 1958-1961 proved that: 1. Vetch shows high suitability as a component of fodder plant mixtures in given sowing seasons. 2. The dynamic of the growth rate of vegetative spring vetch mass in various sowing seasons was different. 3. The highest growth rate of the green mass took place in the period of full bloom and pod formation. 4. Sown together with horse beans, the vetch shows the best development, while bigger additions of oats (50 kg/ha) and sunflower (15 kg/ha) appeared disadvantageous. 5. Mixtures with sunflower rendered higher yield of green mass but had lower dry mass contents and protein, the latter being cropped at a rate similar to that of other mixtures.Pozycja Open Access Terminy siewu i skład mieszanek ozimych z rajgrasami na glebach zwięzłych i lżejszych.(1964) Kopczyński, J.; Ceglarek, F.; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Szczegółowej Uprawy Roślin; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Szczegółowej Uprawy RoślinExperiments have proved that the most suitable term for sowing winter plant mixtures with rye-grass, crimson clover, and villous vetch is, for the West Coast region, the second half of August. If sown later, the green crops were lower and spring harvesting was delayed. When sown later on heavier soil, the mixtures responded weaker and didn’t decrease the crops. In the West Coast conditions, the addition of crimson clover to mixtures with rye-grass and villous vetch exercised a positive influence upon the green mass yield. It was also noted that their influence was greater on heavy soils than on light ones.Pozycja Open Access Wpływ komponentów na rozwój kukurydzy w siewach mieszanych.(1964) Waligórska, A.; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Szczegółowej Uprawy RoślinExperiments were carried out in main and secondary crops on light and heavy soils in the years 1961-1963. Maize was sown as monoculture and in mixtures with sunflower and with podded plants. The results have shown that: 1. Differences in the height of maize stalks manifested themselves 60 days after rise. 2. Within those 60 days, the field pea and the sunflower exercised a negative influence upon the growth of maize while soya and yellow lupine acted positively. 3. A mixture of maize with sunflower and some other podded plants sped up the utilization term to 15-55 days. 4. Mixtures with podded plants showed higher protein contents and better yield.Pozycja Open Access Wpływ nawożenia azotowego na plon mieszanek ozimych.(1964) Balcerek, W.; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Szczegółowej Uprawy RoślinIn the years 1960-1962, researches were carried out at the Agricultural Experimental Stations: Lipki and Ostoja for nitrogenous fertilization of winter catch-crops (winter vetch + rye). The applied fertilization consisted of 20, 40, and 20 + 20 kg N/ha. The fertilizers were applied in two terms and so the mixtures were cut. The obtained results proved that nitrogenous fertilization of winter catch-crops increased the green mass, protein, and carotene yields and sped up their soilage. The dressing of 20 + 20 kg N/ha applied in two terms heightened the protein content in the winter mixtures.Pozycja Open Access Wpływ roślin podporowych na ważniejsze cechy rozwojowe wyki siewnej w uprawie na nasiona.(1964) Pawlus, M.; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Szczegółowej Uprawy RoślinIn the years 1958-1962, investigations were carried out on the influence that the amounts of sowing of four spring grain plant varieties and horse beans produce upon the growth of spring vetch for seed. The results prove: 1. The tested varieties as well as the sown quantity greatly differentiated the vegetative and generative qualities of spring vetch. 2. Of the tested varieties, rye and wheat showed the greatest suitability as components; lesser laying, higher grain yield, and higher coefficients of spring vetch propagation. 3. The bigger the amount of grain plant admixtures and the lesser the amount of spring vetch, the weaker was the vegetative growth of the latter. 4. Spring vetch cropping was above all dependent on the degree of laying. 5. In the existing conditions, the mixtures of spring vetch and "Gorzowska Sztywna" (60 kg/ha and 100 kg/ha) or spring rye (60 kg/ha) appeared best. They proved suitable for mechanical harvesting.Pozycja Open Access Wpływ różnych głębokości orki siewnej i wysokości dawek nawozów azotowych na plon żyta(1964) Kurnatowska, A.; Dzienia, S.; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Ogólnej Uprawy Roli i Roślin; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Ogólnej Uprawy Roli i RoślinThe investigations endeavor to find out what optimal portion and term of applying nitrogen manures as well as what depth of ploughing are most efficient in the increase of rye yield. To that purpose not only the basic portion of nitrogen manure (10 kg in autumn and 20 kg in early spring) was applied but also a supplementary dose of nitrogen manure (30 kg and 60 kg in various phenophases of rye) was given. Ploughing was performed on a depth of 14-16 cm and 20-22 cm respectively. It was found that deep ploughing exercised only a slight effect on the rise of rye yield and that on either depth of ploughing supplementary nitrogen manuring produced a bigger increase in the rye yield than the basic nitrogen and also that a supplementary portion of 30 kg introduced 14 days after the rye had shot, appears most advisable and proves economically justified.Pozycja Open Access Wpływ sposobu pogłębiania orki przedzimowej na dynamikę niektórych właściwości fizyko-chemicznych gleby lekkiej i plony ziemniaków(1964) Laskowski, S.; Zbieć, I.; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Ogólnej Uprawy Roli i Roślin; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Ogólnej Uprawy Roli i RoślinA two-year experiment has shown that Subsoil Winter Ploughing, and a very deep ploughing caused a temporary improvement of the quality of the soil humus thanks to an increase of humic acids to fulvous acids ratio. Deep, deepened and very deep ploughing gives a significant rise in yield as compared with shallow ploughing. Mole ploughing on light soil did not show any positive production effects. The harrowing of the Winter Ploughing causes a deterioration of the field structure and a decrease of the potato yield. However, it has a positive effect on the actual humidity and full water capacity of the soil.Pozycja Open Access Wpływ stanowisk w zmianowaniu na plony buraków pastewnych(1964) Laskowski, S.; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Ogólnej Uprawy Roli i RoślinConsidering the results of the 3 year’s (1960-1963) field experiments carried out on noncomplete weak limed sand in R.Z.D. Lipki it may be stated that: 1. Underployghing of the remainders of the podded plant crop and stubble crop together with farm yard manure cause the preservation of effective nitrogen contents in the soil during the whole vegetative period, while after nonpapilonaceous crops the observed increase in effective contents subsides afterwards, due either to the fact that the beet make use of the availing nitrogen forms or to downwashing. 2. The best yield of fodder beet is to be expected when planted after rye with underploughed stubble crop, or after secondary maize crop that follows a winter sown mixture.Pozycja Open Access Wpływ suszenia ziarna na plony pszenicy.(1964) Duczmal, K.; Duczmalowa, T.; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Fizjologii Roślin; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Fizjologii RoślinInvestigations were carried out upon the influence of thermic wheat seed drying on the rise, growth, and cropping of the plant. Under the influence of drying, the plant always lowers its rise, but a decrease in grain crops (10 to 30%) was shown only by those plants that grew up from seeds harvested in their early-wax and wax phases.Pozycja Open Access Wpływ suszenia ziarna na pobieranie wody i wielkość potencjału redox(1964) Duczmal, K.; Duczmalowa, T.; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Fizjologii Roślin; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Fizjologii RoślinInvestigations were carried out on water intake (sorption) and redox potential during the germination period of wheat grain gathered at its wax-ripe stage and subjected to drying. It was proved that seed drying in higher temperatures (40 and 50°C) caused disturbances in the osmotic water intake as well as changes in the height of redox potential.Pozycja Open Access Wpływ suszenia ziarna na zdolność kiełkowania oraz aktywność katalazy i beta-amylazy(1964) Duczmal, K.; Duczmalowa, T.; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Fizjologii Roślin; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Fizjologii RoślinInvestigations were carried out on the influence of drying grain harvested in various ripening phases on its germinating power and the activity of "catalase and beta-amylase". The obtained results show a close dependence of the quality of the dried grain on the degree of its ripeness, temperature, and the duration of its activity. Drying at higher temperatures caused a decrease in all the examined indices, particularly when the grain was gathered in its early ripening stage.
