IMPACT OF WEATHER CONDITIONS ON TRITICALE OVERWINTERING IN POLAND OVER 1988-1998

Ma│gorzata Czarnecka, Eliza Kalbarczyk

 

ABSTRACT



The 1988-1998 study comprised analysis of statistical relation of degree of overwintering (in the 9-degree scale) and of winter damage (in percentages of sown area) of triticale, grown in field trials and in agricultural production to the air and soil thermic conditions and precipitation from December to March in the three distinguished overwintering zones. Also air minimum temperature at 5 cm above the ground, snow cover absent or less than 5cm thick as well as snow cover of different thickness and duration were analysed. It was found that triticale overwintering was determined mainly by air and soil temperature, especially in December and January, whose largest impact manifested itself in the central part of Poland.

Key words: overwintering degree, winter damage, analysis of regression, soil and air temperature, minimum temperature, precipitation, excessive snow cover.
