    Badania nad określeniem energii i siły kiełkowania nasion wyki kosmatej (Vicia villosa Roth).

    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.

    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 Roślin
    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.
