    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.

    Wpływ roślin podporowych na ważniejsze cechy rozwojowe wyki siewnej w uprawie na nasiona.
    (1964) Pawlus, M.; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Szczegółowej Uprawy Roślin
    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.
