The effect of crop rotation and production technology on the yields of selected winter triticale cultivars

Abstract

In recent years, triticale has been increasingly cultivated in crop rotations with a high percentage of cereals in the sowing structure. One way to counteract the decrease in cereal yields under these conditions is to use a technology that provides plants with optimal growth and development conditions. The study aimed to determine the effect of the integrated and intensive production technology on the yields of three winter triticale cultivars under the different percentages of cereals in the sowing structure. The research was conducted in 2012/2013, 2014/2015, and 2015/2016 in the Experimental Station of IUNG-PIB in Osiny, Poland. The research factors were ‘Cerber’, ‘Alekto’, ‘Fredro’ cultivars, and intensive and integrated production technology. The yields of winter triticale depended mainly on weather conditions during the research period, crop rotation, production technology, and cultivar. Lower cereal percentage in crop rotation resulted in higher yields of triticale. The use of intensive technology produce has contributed to an increase in winter triticale yields compared to the yields obtained after the implementation of integrated technology. Winter triticale cultivar ‘Alekto’ yielded at a higher level under both production technologies than other cultivars. Decreased number of cereals in crop rotation and the application of intensive production technology promoted an increased number of ears per area unit.
