Sorghum (Sorghum bicolor (L.) Moench) is widely cultivated in West Africa (WA) on soils with low phosphorus (P) availability. Large genetic variation for grain yield (GY) under low-P conditions was observed among WA sorghum genotypes, but information is lacking on the usefulness of P-tolerance ratios (relative performance in –P [no P fertilizer] vs. +P [with P fertilizer] conditions) and measur...

STUDY OBJECTIVE To conduct a preliminary study of occupational respiratory complaints in farmers who have experienced organic dust toxic syndrome (ODTS) symptoms. DESIGN Cross-sectional. SETTING An agricultural trade show. INTERVENTION None. MEASUREMENT AND RESULTS Two hundred ninety-seven people (204 men, 93 women) completed a questionnaire about agricultural practices, respiratory hea...

Sweet sorghum (Sorghum bicolor (L.) Moench) is a multiple-purpose crop which has been consumed as either food or feed and recently, industrially cultivated for liquid sugar and ethanol production. Biomass and carbohydrate composition of sweet sorghum are considered as important factors for industrial productions. Thus, in this study fresh stalk yield, total sugars, sucrose content and invert su...

Soaking of cereal grains has been suggested as a method to reduce their phytate content and hence increase their mineral availability. Whole and milled wholegrain, normal and low phytate sorghum and normal maize were studied. Soaking of unmilled sorghum and maize did not result in substantial reductions in phytate or mineral contents. With milled grains, phytate solubilisation was somewhat grea...

Aluminium (Al) toxicity is a major abiotic constraint on grain sorghum (Sorghum bicolor L. Moench) production on acid soils in East Africa. Aluminium in acidic soil inhibits water and mineral uptake from and consequently, reduces plant vigour and yield. A study was done to determine genetic diversity of Tanzania’s sorghum for response to Al toxicity. Five day old seedlings of 98 sorghum genotyp...

Crossbred steers (n = 7; 400 kg BW), fitted with T-type cannulas in the duodenum and ileum, were used to examine the effects of processing method, dry-rolled (DR) vs. steam-flaked (SF) sorghum grain, and degree of processing (flake density; FD) of SF corn (SFC) and SF sorghum (SFS) grain on site and extent of DM, starch, and N digestibilities and to measure extent of microbial N flow to the duo...

to evaluate the effects of biological phosphorous, chemical fertilizers and limited irrigation regime on quantitative and qualitative characteristics of two different grain sorghum cultivars (kimiya and speedeh), this experiment was conducted in research farm of college of agriculture, university of tehran during 2009 growing season. the experimental treatments were arranged as split split plot...

Increasing global atmospheric CO2 concentration has led to concerns regarding its potential effects on the terrestrial environment. Attempts to balance the atmospheric carbon (C) budget have met with a large shortfall in C accounting (μ1.4 3 1015 g C y–1) and this has led to the hypothesis that C is being stored in the soil of terrestrial ecosystems. This study examined the effects of CO2 enric...

Cereal Chem. 85(6):837–842 The objectives of this research were to develop a rapid method for extracting proteins from mashed and nonmashed sorghum meal using sonication (ultrasound), and to determine the relationships between the levels of extractable proteins and ethanol fermentation properties. Nine grain sorghum hybrids with a broad range of ethanol fermentation efficiencies were used. Prot...
