This book was released on 2018-02-13 with total page 18 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2018-02-07 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 book was released on 2021-04-13 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Yield Performance of Corn Under Heat Stress written by Keith Meyers and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Starting in the 1930s, commercial hybrid corn seeds rapidly replaced the once predominant open-pollinated varieties planted by farmers. By the mid-1950s almost all corn grown in the United States was of hybrid varieties. Observers have argued that the drought tolerant qualities of these hybrids were a major factor driving farmers' decisions regarding hybrid adoption, but there is little statistical evidence to substantiate this assertion. Hybrid seeds exhibited other attractive qualities, such as improved performance during prime weather conditions, resistance to wind damage, and increased suitability toward mechanized harvesting. Using historical evidence from Zvi Griliches's archival records, we reconstruct data on hybrid corn adoption and yields at a more disaggregated geographic level than previously available. We match these data with historical weather records to measure the extent to which hybrid seeds mediated the adverse effects of extreme heat. Our findings suggest that hybrid corns grown in Iowa from 1928 to 1942 did exhibit heat tolerance relative to open-pollinated varieties. This result is unique to Iowa as this reduced temperature sensitivity does not appear when comparing hybrid and open-pollinated grown in other states.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Working with Smallholders written by International Finance Corporation and published by World Bank Publications. This book was released on 2023-11-01 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: Smallholder farmers are the stewards of more than 80 percent of the world’s farms. These small family businesses produce about one-third of the world’s food. In Africa and Asia, smallholders dominate the production of food crops, as well as export commodities such as cocoa, coffee, and cotton. However, smallholders and farm workers remain among the poorest segments of the population, and they are on the frontline of climate change. Smallholder farmers face constraints in accessing inputs, finance, knowledge, technology, labor, and markets. Raising farm-level productivity in a sustainable way is a key development priority. Agribusinesses are increasingly working with smallholder farmers in low- and middle-income countries to secure agricultural commodities. More productive smallholders boost rural incomes and economic growth, as well as reduce poverty. Smallholders also represent a growing underserved market for farm inputs, information, and financial services. Working with Smallholders: A Handbook for Firms Building Sustainable Supply Chains (third edition) shows agribusinesses how to engage more effectively with smallholders and to develop sustainable, resilient, and productive supply chains. The book compiles practical solutions and cutting-edge ideas to overcome the challenges facing smallholders. This third edition is substantially revised from the second edition and incorporates new material on the potential for digital technologies and sustainable farming. This handbook is written principally to outline opportunities for the private sector. The content may also be useful to the staffs of governmental or nongovernmental development programs working with smallholders, as well as to academic and research institutions.

Download or read book Genetically Engineered Crops written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2017-01-28 with total page 607 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
