The effect of mineral N fertiliser and sewage sludge on yield and nitrogen efficiency of silage maize

Original language description

A field experiment was conducted on a chernozem soil to estimate fertiliser N efficiency of silage maize (Zea mays L.) by the difference method as influenced by the type of N fertiliser (mineral-MF vs. sewage sludge-SS), and N rate. Eight N treatments were included (0, 60, 120, 180 and 240 kg N/ha prior maize sowing, 60 kg N/ha at planting in MF; 120 and 240 kg N/ha in SS. The average dry mater (DM) yields were 11.2?14.8 t/ha. Average nitrogen uptakes were 88?185 kg N/ha, when the average N contents inDM were 0.8?1.25 %. Nitrogen utilization efficiency (NUE) was relatively stable value for variants with MF. The best use of nitrogen from MF had been reached by N dose 60 and 120 kg/ha. The average values of recovery efficiency of applied N (REN) were calculated 41?57 %. The using of SS increased the yield of silage maize 19?25 % compared to control, above all first and second year after their application. Mineral-fertilizer-N equivalents (MFE) for SS were calculated 55 and 64 %.
