Maize is the most widely grown starch in Ghana, and yet domestic supply does not meet demand, because maize productivity is low. Trials were performed in northern Ghana in 2015 to determine whether hybrid varieties would outperform the varieties planted by farmers and, therefore, increase maize productivity. Two foreign hybrids performed consistently better then Obaatanpa, the most widely used variety in the north. In 2016, Adikanfo, the best performing hybrid, and certified Obaatanpa were made available for purchase at subsidized rates in the communities where the 2015 trials had been conducted. A survey was then carried out to study whether the trials had any effect on technology uptake or behavioral change among farmers in the region and if the varieties performed as well on the farmers’ fields as in the trials. This paper presents the descriptive results of the survey.

Maize is an important staple crop in Ghana, but maize productivity is low. Other countries with similar agroecological conditions have increased maize productivity by increasing the use of maize hybrids. This paper presents the results of maize trials in northern Ghana, in which hybrids were tested to see if they performed significantly better than the varieties planted by farmers. This paper details the procedures of the maize trials and presents descriptive statistics of the trial results. The trials demonstrated that two foreign hybrids performed consistently better than Obaatanpa, the most widely used variety in the north. The foreign hybrids performed consistently well in all districts and appear to be well-suited for planting in northern Ghana.

This report examines the evolution of farm input subsidy programs in Ghana, with a focus on the Planting for Food and Jobs (PFJ) initiative, which was introduced in 2017 and replaced the Fertilizer Subsidy Program (FSP) that was launched in 2008. A review of PFJ implementation reports and other official data sources reveal that information on general program features, such as beneficiary numbers, subsidized input quantities, and program budget is readily available and useful for understanding program design and implementation. National crop production estimates are also reported annually, and these provide evidence of rapid output growth in the agricultural sector, especially within the cereals subsector. However, the implementing agency, the Ministry of Food and Agriculture (MoFA), lacks a system for closely monitoring and reporting PFJ program impacts at farm-level. Consequently, most of the published information on the marginal contribution of PFJ to national crop output is based on simulations, which make strong assumptions about seeding rates, fertilizer use by crop, and input use efficiency on beneficiary farms. With this drawback in mind, these simulations show that PFJ contributed substantially to crop output growth, a result which is not implausible considering the quantities of inputs provided, but one that requires further on-farm validation. Recommendations are offered around beneficiary targeting, interpretation of employment impacts, and the need for regular monitoring of farm-level impacts, all of which will help improve transparency of the program.

Maize is an important food crop in Ghana, accounting for more than 50 percent of the countrys total cereal production. The Ghana Grains Development Project (19791997) and the Food Crops Development Project (20002008) made major investments to improve maize yield. Despite these efforts, the average maize yield in Ghana remains one of the lowest in the world, much lower than the average for Africa south of the Sahara.

African agriculture is currently at a crossroads, at which persistent food shortages are compounded by threats from climate change. But, as this book argues, Africa can feed itself in a generation and can help contribute to global food security. To achieve this Africa has to define agriculture as a force in economic growth by advancing scientific and technological research, investing in infrastructure, fostering higher technical training, and creating regional markets.

Genetically engineered (GE) crops were first introduced commercially in the 1990s. After two decades of production, some groups and individuals remain critical of the technology based on their concerns about possible adverse effects on human health, the environment, and ethical considerations. At the same time, others are concerned that the technology is not reaching its potential to improve human health and the environment because of stringent regulations and reduced public funding to develop products offering more benefits to society. While the debate about these and other questions related to the genetic engineering techniques of the first 20 years goes on, emerging genetic-engineering technologies are adding new complexities to the conversation. Genetically Engineered Crops builds on previous related Academies reports published between 1987 and 2010 by undertaking a retrospective examination of the purported positive and adverse effects of GE crops and to anticipate what emerging genetic-engineering technologies hold for the future. This report indicates where there are uncertainties about the economic, agronomic, health, safety, or other impacts of GE crops and food, and makes recommendations to fill gaps in safety assessments, increase regulatory clarity, and improve innovations in and access to GE technology.
