    In the present study, a field experiment was carried out to evaluate and compare the effects of seed planting and stem cutting method of propagation on two cowpea lines (IT07K-243-1-2 and IT07K-298-15). Data assessed were subjected to student t-test to test for the significant effect of the two methods at p < 0.05. Results showed that growth characters such as plant height, number of leaves, leaf area, above-ground dry mass, leaf area index, leaf area ratio, relative growth rate, net assimilation rate and crop growth rate were significantly enhanced in seed propagation method compared to stem cutting. The yield components such as number of matured pods per plant, pod mass per plant, pod length, pod circumference, pod filling, hundred (100) seed mass, seed mass per plant, average number of seed per pod, harvest index and pod yield per metre square followed similar pattern as recorded for growth characters. Germination potential of the harvested seeds as well as vigour were better in seed planting than stem cutting. Varietal difference showed that line IT07K-298-15 had higher growth, yield and germination potential than IT07K-243-1-2. However, the protein, fat and carbohydrate contents of the latter were higher than the formal. The study concluded that the use of true seed promoted higher productivity. However, planting of stems could still be encouraged on account of a non-significant difference in some of the aforementioned attributes, thereby limiting overreliance on seed as the main source of planting material for propagating the cowpea lines.

    Comparative studies on the growth, yield and bulb quality of two onions (Allium cepa L.) varieties
    (FUTA Journal of Research in Science, 2019) Olayinka, B. U.; Ademolu, O. O.; Akinwunmi, M. A.; Ayinla, A.; Etejere, E. O.
    Onions are vegetables that contain plant potent compounds that have been shown to promote human health in several ways. The biological productivity in terms of growth, yield and bulb qualities have been shown to vary among varietal type. Hence a field experiment was carried out to compare the growth, yield and bulb quality of two onions varieties (Allium cepa L. cv Red and White creoles). The field layout followed complete randomized block design with three replications. The data on biological yield and biochemical parameters were subjected to student t-test at 0.05 level of significance. The results showed that White creole had higher growth than Red creole. However significantly (p≤ 0.05) higher bulb yield was recorded in Red creole (1126kg/ha) compared to White creole (600kg/ha). Parameters such as number of bulb per plant, length and diameter did not show statistical differences. Composition of the bulb in terms of percentage moisture, ash, crude protein, crude fat, crude fibre, carbohydrate and energy value showed values that ranged from 86.1 ± 0.40 - 86.4 ± 0.64%, 0.6 ± 0.00 - 0.7 ± 0.02%, 3.3 ± 0.01- 3.6 ± 0.18%, 0.8 ± 0.01- 0.9 ± 0.01%, 1.7 ± 0.18 - 2.6 ± 0.07%, 7.0 ± 0.47 - 6.1 ± 0.29%, 48.9 ± 1.97 - 47.1 ± 1.93 kcal respectively. The moisture, protein, ash, carbohydrate and energy value of the two varieties did not show statistical differences. The vitamin C and sulphur contents values which ranged from 5.1 ± 0.08 - 3.5 ± 0.28 mg/100g and 248.1 ± 8.10 - 194.7 ± 3.40 mg/kg respectively were found to be significantly higher in Red creole than White creole. The results of this study suggests that Red creole consumption is better in the maintenance of healthy living while, White creole on account of high fibre content could be recommended for non-obese patients with indigestion problem.
