| Changing orchard sprayer technology and rising pesticide costs to fruit growers raise the need to analyze the profitability of alternative sprayer investments. This study analyzes investments in four orchard sprayers for use in Michigan apple production: an air blast sprayer, a tower boom sprayer, a tower boom sprayer equipped with electronic sensors that activate spray nozzles when foliage is detected, and an air curtain sprayer that targets spray with a layer of forced air. Assuming equal pest control efficacy, the study calculates the annualized net present cost per acre of owning and operating each sprayer for ten years using a baseline discount rate of 10 percent over 200 acres of semi-dwarf apple trees. The analysis found the annualized net... |

| Agricultural land use and the management of agricultural lands in Ghana as evidenced from farmer practices have been analysed using descriptive and regression analysis. The analysis shows that different land management practices affect crop yields differently in the different ecological zones. Also, the types of land management practices farmers use differ across the different ecological zones. The policy implication is that agricultural interventions should be developed on the basis of agro-ecological zones, and blanket crop improvement packages should be avoided. The recommended policy action is that food crop farmers should be helped to improve the management of their agricultural lands by ecological zones at two levels. First, the practices that are... |

| Economic policies have had important implications for the role of agriculture in the socio-economic development of Ghana because of agricultures dominance of the economy. The performance of the agricultural sector has generally directed the overall economic performance since independence. The policy of market deregulation in Ghana, including agricultural markets, has not achieved the expected results due to many constraints, the key of which are institutional failures and the slow response of the private sector to take up the agricultural input markets. These have been compounded by the rain-fed agriculture that is predominant in Ghana, such that bad rainfall years have been characterized by low harvests of staple food crops and high food prices, and vice... |

| The dual purpose of the exchange rate (the price of a unit of foreign currency) as a means of allocating scarce foreign currency among competing uses and an important determinant of income distribution through its influence on the returns to those who produce or consume treadables, makes it a prime target as a policy tool, as has been experienced in Ghana. This paper addresses issues of exchange rate management in Ghana in both the pre- and post-independence periods, and how these have affected both micro and macro economic variables. It provides an overview of exchange rate reforms in Ghana over the period since Ghana attained independence from Britain in 1957; and investigates the factors that are most important in determining the real exchange rate in... |

| The magnitude and direction of trade flows in cattle and beef, and how cattle production and beef consumption adjust in response to more open trade in the Central Corridor (an acronym for the sub-region that includes Ghana, Cote d'Ivoire, Mali, and Burkina Faso) have been estimated. A mathematical programming approach was used to model trade in cattle and beef in the West African Central Corridor. Quadratic programming which maximizes the net social surplus in the Samuelson sense under a competitive market framework when farmers are risk averse was applied. Estimates of consumer surplus, producer profits, and government revenue changes were used as welfare indicators. The different scenarios analyzed indicate that there would be an increase in trade in... |
