“…Almost all studies in Italy that have investigated the agronomic or quality traits of sorghum refer to forage (Dolciotti et al 1998;Colombo et al 2007), biomass (Belletti et al 1991;Habyarimana et al 2004) or sweet sorghum (Monti & Venturi 2003;Barbanti et al 2006). White grain sorghum is an interesting crop for the southern regions of the EU.…”

Grain sorghum [Sorghum bicolor (L.) Moench] is a gluten-free grain that is gaining attention as a food crop that can be used in the management of celiac disease. At present, sorghum is widely grown in many semiarid regions of the world. New food-grade sorghum cultivars are of particular interest in Mediterranean countries due to improved quality characteristics and gluten-free status of the grains. Until now very few studies have examined the grain yield (GYLD) and agronomic performance characteristics of food-grade sorghum hybrids in Italy. A 2 year study was conducted to evaluate the agronomic performance of eight food-grade sorghum hybrids representing different maturity classes in trials conducted in Southern Italy. The results showed wide variation in adaptation of these hybrids as measured by differences in GYLD (2.35Á8.50 t ha(1 ) and other phenomorphological characteristics. Of particular interest was the fact that many of the early-flowering hybrids (e.g. SP-X303) performed better than the later-flowering hybrids (e.g. ArchX-02). These results demonstrated that flowering time of hybrid and crop cycle length are important factors to consider in selecting cultivars for production in the Mediterranean region.

“…Starch content (XT) was quantified according to the method of saccharification using hydrochloric acid (Balestrieri and Marini, 1996). Sugar (XZ) was extracted from 10 g of raw material in 100 mL of distilled water (Dolciotti et al, 1998). After filtration the amount of water soluble carbohydrates was quantified according to Fehling method (De Clerk, 1963).…”

Batch testing of biomethanization was conducted on organic matrices from a mixture of grasses (triticale and barley) and legumes (field bean -Vicia faba L. var. minor). These tests were performed in mesophylic conditions (35°C) on previously chopped and ensiled biomass.The three crops have been cultivated in Southern Italy (Puglia region), both as single-crops and intercropping between triticale or barley and field bean, in different mixture combinations, during the season 2009-2010. Emphasis was placed on the determination of the chemical composition of feedstock from the three single species and their different intercropping ratios, mowed at two subsequent stages (milk and dough development of grasses), also assessing their consequent biogas and methane potential yields after silage. Seven overall treatments have been compared: the three species in monoculture (triticale, barley and field bean, respectively); two mixtures between triticale and field bean (with triticale at 70 and 50%, respectively); two mixtures between barley and field bean (again with barley at 70 and 50%, respectively). Immediately after cutting and for the next 90 days, biomass samples were closed into plastic mini-silos, each having a 5-L capacity, in order to simulate the silage process. Thereafter, the batch testing was performed and biogas and methane production have been determined, with respect to the main chemical characteristics of the chopped and ensiled biomass samples, able to affect biogas and methane yield. Considering the single-crop treatments the highest biogas per hectare production has been found with respect to triticale (8737.1 nm 3 ha -1 ) and barley (8837.6 nm 3 ha -1 ), at the first and second harvesting stage, respectively. Concerning grass-legume intercropping, the highest biogas yield (8635.0 nm 3 ha -1 ) was observed with reference to the 70:30 mixing ratio, specifically on barley mowed at the milk development stage. The methane content in the biogas ranged from 61.1% (on a 50:50 mixing ratio of barley at the milk stage) to 53.7% (on a barley monoculture at the dough stage).

“…leaf was thicker) at the booting stage than at one week before panicle initiation stage in both the years. Dolciotti et al (1998) also reported lower SLA at the later growth stages of sorghum crop. In addition, the SLA at one week before panicle initiation stage was lower in the 2009 season than in the 2010 season, probably due to the drought stress at the early growth stage in the 2009 season (Table 1).…”

The chlorophyll meter (SPAD-502) is used to estimate nitrogen status of various crops. However, the relationship between SPAD readings and leaf nitrogen concentration (LNC) in sweet sorghum (Sorghum bicolor) has not been fully established. We examined the relationship between SPAD readings and LNC in sweet sorghum in a two-year study; and the effects of leaf thickness on the relationship was also examined. There was a significant relationship between the SPAD reading and LNC at each of two growth stages, but the correlation was weaker when the data for the two growth stages were pooled. This correlation improved when the specific leaf area was introduced as a second independent variable in the multiple regression analysis. This regression equation was applicable to not only different growth stages but also different seasons. The results suggest that the regression equation developed in this study can help in optimizing nitrogen fertilization for sweet sorghum production.
