Grain yield and its components in triticale grown on a pseudogley soil

Abstract

A field trial was conducted on an acid pseudogley soil during the 2011/12, 2012/13 and 2013/14 growing seasons to evaluate grain yield and its components in four triticale cultivars ('Favorit', 'Tango', 'Odisej' and 'KG-20'). The highest values of grain yield, 1,000-grain weight, number of grains per spike, spike length and plant height in all cultivars were obtained in the year characterised by moderate temperatures during grain filling and high amounts of rainfall in the second part of the growing season. 'Favorit' gave the highest grain yield, the largest number of grains per spike, the lowest 1,000-grain weight and the smallest plant height. The highest 1,000-grain weight and the lowest number of grains per spike were found in 'Tango'. 'KG-20' had the greatest plant height and the lowest average grain yield during the three experimental years, with the lowest grain yield achieved in the driest year, and the highest in the wettest year. 'Odisej' exhibited a high grain yield, fewer grains per spike, and the lowest grain weight per spike compared to the other cultivars.
