Popis: The growth and biomass productivity of kenaf (Hibiscus cannabinus, L.) cultivars Tainung 2 and Everglades 41 were determined under three irrigation applications (low: 25%, moderate: 50% and fully: 100% of maximum evapotranspiration; ETm), four nitrogen dressings (0, 50, 100 and 150 kg hat), two sowing dates, and two plant densities (20 and 30 pl m(-2)) in two field experiments carried out on an representative aquic soil of western Thessaly plain (central Greece), in the period 2003-2005. The results demonstrated a paramount effect of sowing time (and thus the availability of the vegetative growing period) on crop growth and biomass productivity; delayed sowings (after mid-May) may reduce biomass production by 38%. Irrigation water had a significant effect (P 0.05) on biomass accumulation. Cultivars performed similar growth rates (no significant differences), which under full water and nitrogen inputs reached maximum growth rates of 180-220 kg ha(-1) day(-1) which may serve as reference for the assessment of crop performance under production situations at hierarchically lower input and management levels for central Greek conditions.
