    Badania nad określeniem energii i siły kiełkowania nasion wyki kosmatej (Vicia villosa Roth).
    (1964) Mackiewicz, Z.; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Szczegółowej Uprawy Roślin
    Investigations 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.

    Researches 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.

    Rozwój wyki siewnej w siewach mieszanych na zieloną paszę w plonie głównym, wtórnym i poplonach ścierniskowych.

    The 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.

    Terminy siewu i skład mieszanek ozimych z rajgrasami na glebach zwięzłych i lżejszych.

    Experiments 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.

    Wpływ komponentów na rozwój kukurydzy w siewach mieszanych.
    (1964) Waligórska, A.; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Szczegółowej Uprawy Roślin
    Experiments 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.

    Wpływ nawożenia azotowego na plon mieszanek ozimych.

    In 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.

    Wpływ roślin podporowych na ważniejsze cechy rozwojowe wyki siewnej w uprawie na nasiona.

    In 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.
