Abstract:
A field experiment was carried out in the years 2009 and 2010, in the Low Po Valley, with the objective to assess whether the growing season on fiber sorghum can be anticipated in order to be able to harvest the biomass when the weather conditions are still favorable for drying the harvest biomass in the field. Two commercial sorghum hybrids (Biomass 133 and Sucre 506) were compared in combination with three sowing and three harvesting dates. At harvest time, productivity and biometrical characteristics were measured. Our findings indicate that in Northern Italy an early sowing does not allow to anticipate the time of harvest. The highest yields, about 26.0 Mg ha-1 , were obtained by crops sowed within the end of April and the beginning of May, and harvested at the end of September. Indeed, owing to the low temperature the crops sowed within the end of March and the beginning of April showed initially a weak growth compared with the ones sowed at the end of April-beginning of May. Hence, an early early sowing did not lead to an anticipated harvest. Both genotypes reached the maximum accumulated aboveground dry matter at the end of September.
