Investigating the morpho-physiological characteristics of Sorghum (Sorghum bicolor (Moench) varieties for adaptability and productivity in the agroclimatic condition of Malaysia.
Sorghum (Sorghum bicolor Moench) belongs to the Poaceae family, which is commonly known as the grass family. It plays a significant role in agriculture due to its versatility, drought tolerance, and wide range of uses. Due to genetic diversity, and wide variations of environmental conditions, the...

| Summary: | Sorghum (Sorghum bicolor Moench) belongs to the Poaceae family, which is commonly known as the
grass family. It plays a significant role in agriculture due to its versatility, drought tolerance, and wide
range of uses. Due to genetic diversity, and wide variations of environmental conditions, the yield
obtained and nutritional quality from sorghum varieties are inconsistent. However, due to limited
knowledge gap of characterizing sorghum varieties (Bahausa, Sambalma, Kaura, Zabuwa, Janjari, and
Kabo) according to their response to environmental conditions, this study necessitates examining basic
morphology, growth habits, yield components, and nutritional quality of each variety to identify their
effective utilization as food and feed. Treatments were laid out in a randomized complete block design
replicated three times. Data collected on morphological, physiological, and biochemical compositions
were subjected to analysis of variance. The results showed significant (p<0.05) effect on the varieties
for example, Zabuwa having the highest (8668.88 kg/ha) seed yield and Janjari with the least (1796.3
kg/ha) seed yield was attributed to their plant height and leaf morphology. Similarly, the nutritional
quality and quantity of each variety was obtained from the total biomass yield, protein contents, fiber
contents and digestibility which were significantly (p<0.05) different among the varieties. Kaura variety
was evaluated to have the highest leaf number (22), stem girth (23.16 mm), DMY (39200 kg/ha), protein
(13.07%) and digestibility compared with Janjari and SAMSORG45. Based on these findings, varieties
were classified by use: Sambalma is ideal for forage, Janjari for breweries and starch production, while
Kaura, Zabuwa, Bahausa, Kabo, and SAMSORG45 are suitable for forage and seed production.
Therefore, this study concluded that the most suitable sorghum varieties for human and animal feed are
Zabuwa and Kaura respectively. |
