Sorghum (Sorghum bicolor L. Moench) in an important cereal crop of theworld . Performance of sorghum in acid infertile soils that are commonto the tropics is rather poor. Research was undertaken in greenhouseand field conditions to evaluate the differences in growth,grain yield, and nutrient efficiency ratio (NER) of sorghum genotypes grown attheree levels of Al saturation. The grawth of shoots and roots and the grain yields showed significant differences with respect to Al-saturation, genotypes and their interactions. The shoot weights,root weights, and visual scores of the greenhouse study were highly related to grain yields obtained in field. The greenhouse technique adapted in this study appears to be reliable method for separation of genotypes into Al-tolerant and intolerant types. The NER values helped differentiate genotypes into efficient and inefficient utilizers of the absorbed nutrients. The sorghum entries showed intraspecific genetic diversity in growth and NER values for the essential elements in the presence or absence of toxic levels of Al. We concluded that selection of acid soil tolerant genotypes and further breeding of acid soil (Al) tolerantcultivars is feasible in sorghum. |
