Growing Temperature Influence Lignocellulose in Sorghum and Could Lead to a Significant Variation in Feed Value of Fodder Sorghum Genotypes

Sorghum (Sorghum bicolor (L.) Moench) presents a suitable source of green fodder in the livestock sector. However, its use as feed is limited by high concentration lignocellulose. A study was conducted to evaluate influence environment and developmental stage harvesting on lignin, cellulose, hemicellulose selected sorghum cultivars. field experiment laid randomized complete block design replicated three times at Egerton University (0°22′S; 35°55′E Nakuru county), Rongai (0°23′N; 35°51′E county) Marigat (0°46′N; 35°98′E Baringo Kenya years 2019 2020. Twenty different genotypes were grown sampled booting dough stages development. The samples analyzed for content. Plant growth, number days 50% heading, daily average temperatures recorded. Cellulose, hemicellulose, lignin content varied among across environments. lowest cellulose recorded line E6518 when (17.02%) while highest IS11442 (43.87%) from stage. Lignin than harvested had higher Location which distinctively temperature significant (p > 0.05) effect parameters with showing lignocellulose followed Marigat, respectively. positively correlated plant height heading. regression analysis showed negative relationship between heading total sum temperature. Crop stage, genotype, determine sorghum. recommendation region should consider local growing harvesting.
