In the seasons of 1997/1998 and 1998/1999 the influence of sowing material (kemels, spikelets) and sowing depth (2 cm and 6 cm) of winter spelt (Triticum aestivum ssp. spelta) variety Bauländer on yields, and the yield components of chemical composition of grain was tested. The trial was established with two treatments in a split-block design on the experimental plots of Crop and Soil Management Institute in Poznań. It was shown that the use of threshed kernels instead of spikelets as sowing material, caused lower plant losses observed over the winter period. It was caused by an even distribution of plants in the row and a lower competition between the plants. Grain yields significantly differed depending on sowing depth. Deep sowing was more favourable (6% yield gain), mainly when spikelets were sown (12.8% yield difference). When threshed kernels were sown, lower plant losses, a higher ratio of productive tillering, a higher kernel yield, and a higher number of kernels in spike and 1000 kernels weight were observed. Other characters were better for spikelets as sowing material. Deep sowing is better for spelt, as significantly higher kernel yields were observed especially when spikelets were sown. At that type of sowing material a higher number of spikes per 1 m2 is obtained. Sowing at a lower depth in spelt is followed by a higher number of kernels in spike, its higher density, significant higher content of protein and ash components in the dry matter of kernels.
