The effect of the soil tillage methods for forecrop and N-mineral fertilization on the yield of winter triticale (× Triticosecale sp. Wittmack ex A. Camus 1927)

Abstract

The aim of the research was to evaluate the effect of three different methods of soil cultivation for the forecrop on the yield and protein content in winter triticale grain depending on the amount of mineral nitrogen used. The yield of winter triticale grain depended the most on the distribution and sum of rainfall and on the doses of mineral N. A significant impact of the increasing total amount of rain and the distribution of precipitation in the years and months of the research on most of the studied features of triticale was found. The average triticale grain yield and protein content were significantly higher when soybean forecrop was grown using the reduced and strip-till method than after traditional plow cultivation. N doses from 60 to 180 kg ha–1 had the highest, but, on average, insignificantly differentiated impact on the yielding of triticale in the years of the study. N fertilization did not differentiate the number of spike-bearing stalks or the weight of 1000 grains. The triticale yield and protein content increased significantly up to the dose of 120 kg N ha–1.
