3 Maize cultivati<strong>on</strong> <strong>in</strong> Europe<br />

3.1 Crop descripti<strong>on</strong><br />

Maize is basically a tropical grass, and it requires high <strong>in</strong>sulati<strong>on</strong> and warmth. An average<br />

temperature of 20 – 24°C is optimal, and <strong>the</strong> temperature should not s<strong>in</strong>k below 14°C at night. The<br />

m<strong>in</strong>imum for germ<strong>in</strong>ati<strong>on</strong> is 8°C. Never<strong>the</strong>less, maize is cultivated <strong>on</strong> every c<strong>on</strong>t<strong>in</strong>ent except<br />

Antarctica. Depend<strong>in</strong>g <strong>on</strong> variety and local climate, maize may need between 70 and 210 days for full<br />

development.<br />

Silage maize is cultivated for feed and is ma<strong>in</strong>ly used <strong>on</strong>-farm. Gra<strong>in</strong> maize may be used for feed<br />

(poultry, corn-cob-mix for pigs), food (maize-meal-products, snacks, cornflakes) or for <strong>in</strong>dustrial<br />

purposes (starch, paper <strong>in</strong>dustry). Temperature and precipitati<strong>on</strong> are major factors <strong>in</strong>fluenc<strong>in</strong>g <strong>the</strong><br />

type of maize producti<strong>on</strong> (see Figure 1). From north to south and from oceanic to more c<strong>on</strong>t<strong>in</strong>ental<br />

regi<strong>on</strong>s, precipitati<strong>on</strong> from April to October decreases and temperature <strong>in</strong>creases. In general, <strong>the</strong><br />

shorter and wetter climatic c<strong>on</strong>diti<strong>on</strong>s <strong>in</strong> north-western European regi<strong>on</strong>s are more suitable for silage<br />

maize, because it can be harvested for this purpose while still unripe, while gra<strong>in</strong> maize producti<strong>on</strong><br />

dom<strong>in</strong>ates <strong>in</strong> dryer and warmer regi<strong>on</strong>s of central and sou<strong>the</strong>rn Europe.<br />

In additi<strong>on</strong> to climatic c<strong>on</strong>diti<strong>on</strong>s, regi<strong>on</strong>al needs for specific maize commodities, like <strong>on</strong>-farm use of<br />

silage for livestock-feed<strong>in</strong>g, or <strong>the</strong> presence of agro-fuel or gas facilities, can <strong>in</strong>fluence <strong>the</strong> farmers’<br />

decisi<strong>on</strong> for producti<strong>on</strong> type.<br />
