U radu se iznosi kratak pregled podrijetla i širenja kulture agruma u svijetu. Iznosi se detaljan pregled povijesti uzgoja agruma u dolini rijeke Neretve i literaturnih izvora o hrvatskom agrumarstvu od prvih početaka do danas. Opisano je stanje proizvodnje, problematika i smjernice za daljnji razvoj. Rezultati istraživanja odnose se na dinamiku rodnosti mandarina u pokusnom agrumiku za razdoblju od 5. do 21. godine starosti stabala. Ustanovljen je broj dana od cvatnje do zrelosti za vrlo rane (Goki Wase): Ichimaru, Wakiyama, Ueno, Zorica, Chahara/Tahara, rane (Wase): Okitsu, Miho, Kawano, Miagawa, srednje zriobe (Nakate): Hharaguchi i Saygon), kasne (Futsu): Owari i Ootsu No 4 i vrlo kasna Aoshima.The paper presents a brief overview of the origin and spread of the citrus culture in the world. Detailed history of citrus in the Neretva valley and the literature sources of Croatian citrus production from the beginning to today is outlined. It describes the state of production problems and guidelines for further development. Survey results are related to the yield dynamics of mandarins in trial citrus orchard for a period of 5 to 21 years old trees. Determined is the number of days from flowering to maturity for very early varieties (Goki Wase): Ichimaru, Wakiyama, Ueno, Zorica, Chahar/Tahara, early varieties (Wase): Okitsu, Miho, Kawano, Miagawa, medium maturity varieties (Nakata): Hharaguchi and Saygon), late varieties (Futsu): Owari and Oots No 4 and very late variety Aoshima
