    Okresy krytyczne w gospodarce wodnej rzepaku jarego

    In the years 1957-1960 pot experiments were carried out to examine the periods of the critical water point of two summer swede-like rape varieties: Mazowiecki and Bronowski. 3 combinations with stabilized soil moisture (25, 40, 70 % of full moisture capacity) have been employed during the whole vegetative period and 5 combinations with alternating moisture stages in 5 different subperiods of vegetation. The Mazowiecki rape proved vulnerable to drought in the phase between germination and shooting, and in the time of blooming. The Bronowski variety, on the other hand, showed the same symptoms but in the phase of rapid growth and ripening. The experiment has shown that Mazowiecki rape proves more resistant to drought than the Bronowski variety and thus more suitable for planting in the natural conditions of West Pomerania.

    Porównanie zawartości wody w poszczególnych poziomach i profilach niektórych gleb w drzewostanach sosnowo-bukowych
    (1964) Borowiec, S.; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Gleboznawstwa
    Comparisons of water contents made in soil profile under pine-beech cover down to a depth of 150 cm.have shown that brown acid soils originating from loose soils formed on day possess the biggest quantity of water. The brown acid soils originating from loose a sand soils possess less water, while least of it possess soils being in their first phase of development on buried podsol soils of loose sand origin.

    Wodne okresy krytyczne w rozwoju lnu włóknistego
    (1964) Dmochowski, J.; Gwizdek, S.; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Fizjologii Roślin; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Fizjologii Roślin
    In the years 1957-1961 pot experiments were carried out to examine the influence that various stages of soil moisture exercisy upon the development and yield of flax of the LCSD 210 variety. The experiments involved 4 moisture combinations (20, 30, 50 and 70 % of full water capacity) and 16 other combinations in which drought was employed (20 % of soil moisture) and were carried out in one the vegetation subperiods. It has been found that flax cropped best when a moisture stage of 70 % was existent during the whole vegetative period, and that the critical water points of the mentioned plant occured in the subperiod of rapid growth.

    Wpływ dynamiki uwilgotnienia żuławskiej mady ciężkiej na przyrost masy organicznej i plony pszenicy ozimej oraz buraków cukrowych
    (1964) Laskowski, S.; Zawistowski, F.; Krużycka, M.; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Ogólnej Uprawy Roli i Roślin; Wyższa Szkoła Rolnicza w Szczecinie. Z R.R.Z.D. w Starym Polu; Wyższa Szkoła Rolnicza w Szczecinie. Z R.R.Z.D. w Starym Polu
    Investigations carried out in 4 years (1957-1960) on a set field in R.R.Z.D. Stare Pole have brought evidence that even layers of heavy alluvials are in spring time lacking oxygen. In the lower parts of the soil profile the period of optimal moisturing begins late, not till the middle of June, and lasts till the third decade of September. The high water levels occuring in the layers under arable soil in the Żuław alluvials exercise detrimental influence on the incre ase of organic mass as well as on the yields.

    Wpływ rzeźby terenu i gleby na bonitację drzewostanów bukowych w Puszczy Bukowej pod Szczecinem
    (1964) Borowiec, S.; Wyższa Szkoła Rolnicza w Szczecinie. Katedra Gleboznawstwa
    Investigations have shown that, quite independently from the sort and quality of the soil, the best valuation was given to the beech cover on low situated land (1-1.2) and on slopes (1-1.8). On sandy elevated ground (clay sands) and on flatland (no matter what kind of soil), it received somewhat worse valuation (1.2-11.1 and 1.3-11.3 accordingly), while the worst valuation was observed on clayey ridges (11.6-111.0).
