The influence of nitrogen fertilization on protein yield and nutrient uptake in different triticale genotypes

Abstract

Triticale is a first man made crop was designed in order to obtain a cereal, which combines good quality grain yield from wheat parent with tolerance to abiotic and biotic stresses (Giunta et al., 1999; Milovanovic et al., 2001; Ortiz–Monasterio et al., 2002). Triticale has potential of both parental species, strains and cultivars were found tolerant to drought (Jessop, 1996), soil acidity and aluminium toxicity. (Aniol, 2002; Baier et al., 1998; Milovanovic et al., 2001). In Serbia triticale covers about 35000 ha year for the period 2000–2004 (Statistical Year Book). Milovanovic et al. (1994) found that grain yield and certain quality parameters in winter hexaploid triticale were more dependent on season conditions in comparasion with wheat. High protein contents are characteristics for triticale. (Koc and Szymczyk, 1997; Milovanovic et al., 2001; Gastal and Lemaire, 2002; Gulmezoglu et al., 2006). Lorenz (1974) and Giza (1991) cited that triticale grains contained higher amount of P, Mg, Mn, Fe and Cu that wheat. The objective of this study was to find out the effects of different nitrogen rates to the protein yield of different triticale genotypes and the contents and uptakes of N, P, K and Ca.
