Sažetak
Field trials (2010 – 2012) were conducted to study the influence of the year (a1 = 2010; a2 = 2011; a3 = 2012); irrigation treatment (b1 = control; b2 = 60 to 80% field water capacity (FWC), b3 = 80 to 100% FWC) and N fertilizers (c1 = control; c2 = 100 kg N ha-1; c3 = 200 kg N ha-1) on grain yield (GY) and following yield components: cob length (CL), cob height (CH), grain number/cob (GN/C) and correlation connections between the tested variables. GY (P < 0,05; a1: 8.6 to a3: 8.3 t ha-1, CH (P < 0.01; a1: 97.4 to a2: 133.5 cm), CL (P < 0.01; a1: 18.6 to a3: 21.4 cm) and GN/C (a1: 566 to a3: 628) were year depenedent. Irrigation water increased (P < 0.01) GY (b1: 7.5 to b3: 9 t ha-1), CH (a1: 115.1 to a3: 125.8 cm) and GN/C (b1: 536 to b3: 612). The larger amount of N fertilizers increased GY (P < 0.01; c1: 6.5 to c3: 10.3 t ha-1), CL (c1: 18.4 to c3: 20.9 cm), GN/C (c1: 536 to c3: 651) and CH (c1: 113.5 to c3: 124.8 cm). Strong postivie correlation is between GY and CL (r = 0.55) and GY and GN/C (r = 0.62).
