  • Abstract:

 The effect of nutrient sources on vegetative and pod attributes of Sesamum datum was investigated in Anyigba, Kogi State, Nigeria. Seeds of sesame were broadcast in five buckets of 5L size filled with sandy loam soil. The buckets were kept at the Nursery wing of the Research Garden of the Department of Biological Sciences, Kogi State University, Anyigba, Nigeria. When seedlings were fully established, four raised beds, each of size 270 cm by 180 cm, were prepared. Cow dung, poultry droppings and NPK were applied to the first three beds while the fourth bed was unfertilized control. Each of the beds was replicated three times and the experimental design used was the completely randomized design CRD. Twenty-five seedlings were transplanted to each bed three seedlings per hole and two weeks after transplanting, each stand was thinned to two plants. At 50 percent flowering, plant height, leaf area, number of leaves per plant, number of branches per plant, number of nodes per plant and stern diameter were determined. After harvest, the final plant height, pod length, pod width, number of pods per plant, number of seeds per pod and weight of an hundred seeds were also determined. Data collected were subjected to analysis of variance ANOVA while means were separated using the least significant difference LSD. The only characters that show significant variation in response to nutrient sources are plant height and pod width. All the other characters do not vary significantly, implying that the majority of sesame phenotypic characters are strongly under genetic control.
