The contribution of soil tillage and nitrogen rate to the quality of maize grain
MetadataShow full item record
A soil tillage system adjusted to the soil type and agro-ecological conditions, togetherwith the optimal nutrient supply, is a prerequisite for high maize (Zea mays L.) yield. However,there is little knowledge about the inﬂuence of soil tillage and nitrogen (N) rates on maize grainquality. A study was initiated in 1978 in Zemun Polje, Belgrade, Serbia, on the chernozem soil type.The eﬀects of three N rates—0, 180 and 240 kg N ha−1—within three tillage practices—no-tillage,reduced and conventional tillage—and their inﬂuence on grain yield (GY) and the content of proteins,starch, oil, total tocopherols and carotenoids, phytic phosphorus (Phy), glutathione (GSH), phenolsand inorganic P (Pi) in maize grain were analysed in the period 2016–2018. Diﬀerences in maizeGY were 2.57 and 3.01 t ha−1for reduced- or no-tillage, respectively, in comparison to conventionaltillage. Conventional tillage and higher N rates contributed to the increase in maize yield and thegrain nutritional quality with r...egard to the increased level of proteins, GSH and Phy. On the otherhand reduced inputs were beneﬁcial only for grain quality, in relation to the increase in tocopherolsand phenols.
