Sažetak
The goal of this research was to determine the influence of alternative systems of crop management (organic and integrated) and endomycorrhiza on vegetative growth and yield of lettuce. During 2002 two-factor trial with three repetitions and split-plot design was set up in Pula. Main factor &#8220 ; crop management&#8221 ; had three levels (organic, integrated and conventional) while the sub factor &#8220 ; mycorrhiza&#8221 ; had two levels (lettuce seedlings inoculated with encomicorrhizal fungus and non-inoculated seedlings). On plots assigned for organic crop management, pea plants grown on the plots before the lettuce were mowed and used as mulch. Other plots were mulched with black polyethylene film. Lettuce seedlings were planted with root ball ; fertilization and cultivation measures were performed according to basic principles of organic, integrated and conventional crop management system. The biggest diameter of heads had lettuce from integrated crop management system (17% bigger than lettuce from organic system). Inoculated plants also had 6% bigger diameter than non-inoculated. Marketable heads from integrated system achieved 13% bigger mass than lettuce from conventional system and 30% bigger than plants from organic system. The biggest yield of lettuce was achieved with integrated crop management (35.51 t/ha) and it did not statistically differ from the yield from conventional crop management (31.05 t/ha). Both systems had significantly bigger marketable yield compared with organic crop management (21.65 t/ha).
