Effect of tillage system and nitrogen fertilization on the yield of selected spring triticale varieties

Abstrakt

The aim of this study was to determine the effect of varying levels of nitrogen fertilization (0, 70, 100 kg ha-1) on yield of spring triticale varieties Milewo, Mazur, Puzon and So- pot under conditions of simplified and traditional tillage. The re- search was conducted in 2017, 2018 and 2020 in Experimental Station of IUNG-PIB in Osiny on soil of good wheat complex. The yield level of spring triticale was affected by the course of weather conditions during the study period, tillage system, nitro- gen doses and variety. Under conditions of more favorable pre- cipitation distribution during the growing season (2017, 2018), grain yields were 32% higher than in 2020. The traditional till- age system ensured higher yields of spring triticale. The applied rate of nitrogen fertilization of 70 kg ha-1 proved to be sufficient for spring triticale yielding under experimental conditions. Under both tillage systems the highest yields were obtained from So- pot. Under conventional tillage Milewo and under reduced tillage Mazur yielded similarly to Sopot. The lowest yield was obtained from Puzon
