Improving agriculture in Nigeria through public-private partnerships

The agriculture sector in Nigeria has remained largelylargely undeveloped. The reason for this is due to the limited public sector funding in the different agricultural value chains including research and development. On the other hand, there has also been very minimal private sector investment in the sector. The cause of this is a lack of incentive for the private sector in Nigeria to invest in sectors like agriculture...

An evaluation of the impact of the management practices and how they impact on employee-engagement: Employees’ perceptions

The employer-employee relationship has always been governed by the understanding that the employee is simply a hired hand to complement the business owner in the process of achieving a firm’s set objectives. The rest of the other activities and phenomena are taken for granted – ‘I employ you, you do your work I pay you’, so the circle continues. The employer drives the employee to perform to...

Mechanisms of aerenchyma formation in maize roots

Respiration is very sensitive to waterlogged conditions. Under these conditions, plant roots suffer from lack of available oxygen. In fact, waterlogging reduces the exchange of gases between the plant and the atmosphere. When plants cannot receive sufficient oxygen level for respiration, they form aerenchyma in their roots which function as reservoirs of oxygen in the submerged plant. Aerenchyma is formed in maize (Zea...
