Sažetak
Maize is main field crop on arable land of Croatia, Serbia and neghbouring countries. In the period 2006-2010 maize was grown in Hungary on1149410 ha (25 % of arable lands), Croatia 298697 ha (34 %) and Bosnia Herzegovina (B&H) on 189613 ha (19 %). Republic of Srpska participating with 75% of maize harvested area of B&H and maize yields in this enthity are something higher (4.60 t ha-1) than in remaining enthity (4.46 t ha-1) of the country (Federation of B&H). In general, maize participating with about 30% og arable lands in area covering the mentioned countries. Average yields of maize in the tested period were 6, 17 t ha-1 (Hungary), 4, 86 t ha-1 (Serbia), 6, 76 t ha-1 (Croatia) and B&H (4, 56 t ha-1), respectively. Also, in the 2006-2010 period were found considerable variations of annual maize yields as follows: from 3.6 to 7.5 t ha-1 (Hungary), from 3.2 to 5.9 t ha-1 (Serbia), from 4.9 to 8.0 t ha-1 (Croatia) and from 3.2 to 5.1 t ha-1 (B&H). Weather characteristics, especially quantity and distribution of precipitation and air-temperatures are main factors of maize yield variations among years. In general, the lowe precipitation and the higher air-temperatures in summer, especially in July and August, than usual are in close connection with the lower yields of maize. The growing seaosn 2012 was unfavorable for maize growing because of drought and high air- temperatures, especially in August. Modeare supplies of soil water in the presowing period was additional unfavorable factor. According estimation, maize yields in 2012 are as follows: 4.2 t ha-1 (Croatia), 4.05 t ha-1 (Hungary) and 3.12 t ha-1 (Serbia) and they are lower than in especially favorable growing season 2010 for 40%, 37% and 44% respectively.
