Effect of sowing time on yield of ZP maize hybrids
These experiments were conducted in the period 2003-2008 in Zemun Polje. Five hybrids were investigated in six sowing dates - on April 5th (Sd1), 15th (Sd2) and 25th (Sd3), and on May 5th (Sd4), 15th (Sd5) and 25th (Sd6). Three unfavorable years for the maize production were distinguished in this pe...

| Summary: | These experiments were conducted in the period 2003-2008 in Zemun Polje. Five hybrids were investigated in six sowing dates - on April 5th (Sd1), 15th (Sd2) and 25th (Sd3), and on May 5th (Sd4), 15th (Sd5) and 25th (Sd6). Three unfavorable years for the maize production were distinguished in this period: 2003 with 210.0 mm, 2007 with 290.1 mm and 2008 with 224.6 mm of precipitation; 2005 was moderately favorable, with 387.4 mm of precipitation. Two years were favorable for the maize production, both in terms of precipitation amounts and distribution: 2004 with 427.6 mm and 2006 with 417.1 mm. The highest average yield was achieved in Sd2 (11.21 t/ha - 100%). On the other April sowing dates, average yield was lower: on Sd1 - 11.04 t/ha (98.48%), on Sd3 - 10.97 (97.86%). The effects of the May sowing dates were significantly lower comparing with the Sd2: Sd4 - 10.53 t/ha (93.93%), Sd5 - 10.46 t/ha (93.31%) and Sd6 - 9.71 t/ha (86.62%). The highest yielding hybrid was ZP 684 (11.16 t/ha). These results doubtlessly point to the mid April sowing date as an optimum for maize in Serbia. |
