In the years 2009 and 2010, among the activities of the project “Filiere Energetiche per il Sud Italia”, two field experiments comparing sorghum genotypes were carried out in the inner part of Campania Region: Montefalcone (BN) e a Sant’Angelo dei Lombardi (AV). In the year 2009, 12 sorghum hybrids were compared using a strip plot experimental design, with three replications and plot of 280 m2. In the year 2010, 15 cultivar were compared (only 8 of them belong to the group compared in the precedent year) using a randomized block design with three replications, nad plots of 50 m2. At harvesting time were measured: the biometric characteristics culm density, culm height, culm basal diameter; the resistance to lodging, the biomass yield and its moisture content, the fraction of leaves, stems and panicles over the total aboveground biomass, and the sugar concentration of the stem juice (° Brix). The year 2009 was a dry season, whilst the year 2010 was a rainy seasons. The type of season substantially influenced the growth and productivity of the crop: in 2009 the average plant height was 171 cm and the dry matter yield 12.8 t ha-1; in 2010 the average height was 300 cm and the dry matter yield 16.0 t ha-1. The most promising genotypes were ‘Bulldozer’ and ‘Goliath’, with dry matter yields overcoming 20 t ha-1. Good performances were observed for ‘Biomass 150’ and ‘Sucre 506’, even though the last genotype is susceptible to lodging. The higher values for sugar content (15.4-16.5 °Brix) were measured for ‘Biomass 150’, ‘Sucre 506’, ‘Goliath’, ‘Herkules’, ‘Mitril’ e ‘Trudan HL’.
