There were six treatments which were replicated three times. The experimental was layed out in RCBD (randomized complete design). The treatments consisted of 2cm, 4cm, 6cm, 8cm, 10cm and 12cm sowing depth. Analysis of variance revealed a significant effect of depth of sowing on the growth performance of Maize plant (Percentage of plant emergence at 10 days after sowing, number of plant leaves at 15 days after emergence, plant height at one month after emergence and number of emerged plants after sowing by counting stand plants). Sowing at depth of 6cm produced the tallest plant, highest number of leaves per plant, the plant emerged early with 100% emergence. The deepest sowing depth showed poor performance in the parameters considered. Thus for similar agro ecologies of Kelem meda, it is better to apply...

To this end, we used the most recent World Bank Enterprise Survey (WBES) of firms from 19 African countries. Our empirical investigation using multilevel logistic regression has drawn three important conclusions. First, there is no significant relationship between firm-specific factors, such as age, ownership, and exporting, and firm innovation. Nonetheless, firms’ propensity to innovate is significantly determined by the size of the firm, R&D expenditures, on-the-job training (OJT), and capability of managers/owners to adopt new technologies. Second, the innovation performance of firms is significantly affected by regional institutional quality. Third, among different regional institutional arran...
