Study of the Yield and Nutrient Content of Various Triticale Varieties (× Triticosecale)

Abstract

Between 2017 and 2020, the yields and green yields of different triticale varieties and the most important nutritional parameters of triticale silage were investigated in Szarvas. The plots were sown in 4 replicates in autumn each year in a block system experiment and each plot received the same agro-technique. The earliest date of the 1st sampling in each treatment was timed to the optimal growth stage for triticale (the ear in boot was 6 cm) followed by three additional sampling. Cut 2 to 4 took place nearly every 7 days. Among the triticale varieties (genotypes) tested in the experiment, Hungaro, Dimenzio, GK Szemes and GK Maros. Between 2017 and 2020, the grain yield averages of the varieties ranged from 4.39 to 5.22 t/ha. From the first sampling date, the varieties were able to produce an average green yield of 16.6 to 26.3 t/ha with a dry matter content of 30%. At the second sampling date, the most dynamic increase was green yield 31.2 t/ha and 30.1 t/ha. By the third harvest date, the best yields were around 28.1-34.4 t/ha. At the fourth sampling time, the average yield increase of the varieties was dynamic and ranged from 26.4 to 41.5 t/ha. At the first sampling, the best fibre digestibility (NDFd48) was measured to be 67.4-73.2 %, which steadily decreased at subsequent samplings. At the fourth sampling, the worst fibre digestibility was measured to be 52.4-60.1 %, which represented a significant decrease at all sampling times.
