Abstract
Two-factorial field experiments were conducted at the Prusy Experiment Station near Kraków from 1999 to 2001. They involved three spring triticale cultivars (Migo, Kargo and Wanad) and two seeding rates (400 and 500 kernels per m2). The soil type was degraded chernozem classified as the very good wheat complex. The grain yields of spring triticale varied between years and were affected by cultivars and seeding rates. Of the studied cultivars, Kargo gave higher yields than Migo (+8.2 dt/ha) and Wanad (+5.4 dt/ha). The grain yields of Kargo i Migo were increased by higher seeding rates. Cultivar had a significant effect on 1000-grain weight. Less apparent effects of cultivar were observed for the degree of tillering, length of ears and height of plants. No effect of cultivar was noted for the number of spikelets and kernels in an ear. Seeding rate significantly modified the components of yield structure and characteristics of spring triticale morphotype. Increasing seeding rate resulted in higher number of ears per area unit, higher 1000-grain weight and enhanced height of plants. In contrast, number of spikelets and kernels in an ear and its length were decreased.
