abstract:
Abstract. The research was carried out in the years 2001-2003 in the fields of the Zawady Experimental Station owned by the University of Podlasie. The field experiment was a 4-replication trial established in the randomised blocks design. Two factors were analysed in the study: cultiva-tion technology differentiated in terms of fertilisation and protection, and spring wheat variety. Factor I included the following cultivation technologies: extensive, conventional and intensive. Varieties, O1 – Opatka, O2 – Hezja and O3 – Torka, constituted factor II. Determination of sprout-ing in ears by means of the Schleiper method was carried out after harvest. The ears were stored for 3, 6 and 9 days at the temperature of about 20ºC and air humidity of 96-98%. The evaluation of sprouting made it possible to prove significant differentiation of the varieties in respect to their predisposition to sprouting at successive assessment dates and in successive years. The highest differentiation of varieties was found on the 3rd day of the assessment. According to the class divi-sion and depending on the sprouting bonitation, all the evaluated varieties were classified as belong-ing to the second class which is characterised by medium resistance to sprouting (sprouting within the limits of 1.6-3.5). The sprouting level varied in the years. In all the varieties the highest level of sprouting was observed in the year 2002 when the precipitation sum in the period from April to August was the highest. Distinct tendency was observed towards changes in predisposition to sprouting as a result of the application of varying cultivation technologies. The grains of all the varieties under intensive cultivation were characterised by the highest level of sprouting.
