A summary of experimental research in Sorghum.
=================≈=========================
Sorghum is the most importance and the first stable food crop in Somalia. Bioticand Abiotic affects the yield, quantity, quality of the crop.
The study was aimed on the evaluation of new varieties of sorghum by comparing them with the local variety ( Baidoa local variety) in terms of their morphological traits, yield and yield components, and adaptation to agro-climatic conditions. The experiment was conducted at Zamzam University in Baidoa. The experiment was laid out in a Randomized Complete Block Design (RCBD), with three replications; each replication consists of three plots.
This generally makes nine plots in all replications. The investigated treatments were (Sorghum Seso3, Sorghum Kobla, and Sorghum white variety-in local name. The study indicated that varieties resulted in highly significant difference on date of flowering, maturity, plant height and grain yield. Also, results showed that the earliest date of flowering (53.33 days) was observed from the variety Local Sorghum while the latest (77.00 days) was showed by Sorghum Seso3. Also the earliest date of maturity (94.67 days) was observed from Local Sorghum, while the latest date of maturity (121.00 days) was observed from Sorghum Seso3.
The highest of plant height (2.75m) was recorded from (Sorghum Seso3), while the lowest (1.55m) was recorded from Sorghum Kobla. Also, the highest of panicle length (22.00cm) was obtained Sorghum Kobla and the lowest was recorded (6.98cm) from Local Sorghum. Similarly the highest of panicle weight (60.00g) was obtained Sorghum Kobla and the lowest was recorded (32.77g) from Local Sorghum. On the other hand, the highest grain yield (3.83t/h) was recorded from Sorghum Seso3, and (3.00t/h), was recorded from Sorghum Kobla. While, the lowest grain yield (2.50t/h) was documented from the treatment Local Sorghum.
In general the sorghum varieties do not show a significant difference in harvest index. Even though there was significant difference among the varieties, as the result of the test showed in terms of high grain yield production, plant height, and straw yield was better in variety Sorghum Seso3 seem better for plant growth, field management, pest and disease resistance and well adapted environment and agro-ecological condition and could be done for further production.
Finally, it can be recommended that variety Sorghum Seso3 seem better for plant growth, yield, field management, and pest and disease resistance in the study area. For reliable recommendations, further research might be important to verify across a different locations.
