Download or read book Factors Affecting Adoption of Improved Maize Seeds and Use of Inorganic Fertilizer for Maize Production in the Intermediate and Lowland Zones of Tanzania written by Aloyce R. Kaliba and published by . This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper examines factors influencing the adoption of improved maize seeds and the use of inorganic fertilizer for maize production by farmers in the intermediate and lowland zones of Tanzania. The results indicate that availability of extension services, on-farm field trials, variety characteristics and rainfall were the most important factors that influenced the extent of adopting improved maize seeds and the use of inorganic fertilizer for maize production. Farmers preferred those varieties which minimize field loss rather than maximizing yields. Future research and extension policies should emphasize farmer participation in the research process and on-farm field trials for varietal evaluation and demonstration purposes. Key Words: adoption, agroecological zones, improved maize seeds, new technology, Tanzania.

Download or read book Fertilizer Quality and its Impacts on Technical Efficiency and Use Intensity in the North China Plain written by Ling Yee Khor and published by Cuvillier Verlag. This book was released on 2014-11-19 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fertilizer has helped the growth of agriculture for decades. However, its overuse in some regions has caused environmental and health problems due to pollution and contamination of groundwater. Fertilizer quality is another cause for concern in many countries, as the actual nutrient content may not match the labeled content on the packaging. The North China Plain is a region affected by both fertilizer overuse and quality problems. This study delves into the issue using economic models and survey data of farm households. Is the effectiveness of fertilizer overstated? How do farmers respond to uncertainty in fertilizer quality? Can they differentiate between good and poor quality fertilizer?
Download or read book Decentralization agricultural services and determinants of input use in Nigeria written by Akramov, Kamiljon T. and published by Intl Food Policy Res Inst. This book was released on with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The substantial differences in agricultural productivity between Asia and Africa can be largely explained by differences in use of modern inputs. The evidence suggests that better access to infrastructure (such as roads and irrigation) and agricultural services has given Asian farmers significantly better access to modern inputs, while Sub-Saharan African farmers without such an access are not able to fully exploit the benefits of modern agricultural inputs. This brief discusses the relationship between agricultural service provision and modern input use by farmers in Nigeria, with a focus on the differences among states and local government areas (LGA).

This book was released on 2014-06-27 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: By 2050, climate change is likely to reduce maize production globally by 310 percent and wheat production in developing countries by 2934 percent. Even without climate change, the real costs of wheat and maize will increase by 60 percent between 2000 and 2050; climate change could make the figure substantially greater. Food security, despite the above, may be possible if agricultural systems are transformed through improved seed, fertilizer, land use, and governance.
Download or read book Sustainable Agricultural Development written by Mohamed Behnassi and published by Springer Science & Business Media. This book was released on 2011-02-09 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to many challenges (i.e. climate change, energy, water and land shortage, high demands on food, land grabbing, etc.), agriculture production potential is expected to be seriously affected; thus, increasing food insecurity and hunger in many already affected regions (especially in Africa). In this context, sustainable agriculture is highly recommended as an eco-system approach where soil, water, plants, environment and living organisms live in harmony. Innovative technologies and research should be developed to ensure sustainable agriculture and productivity using modern irrigation systems, improved varieties, improved soil quality, etc. In the meantime, the preservation of natural environment should be based on resource conservation technologies and best management practices. Sustainable Agricultural Development, not only raises the serious ethical and social issues underlying these huge environmental problems, but also aims at presenting successful experiences from all over the world in relation with sustainable farming, sustainable management of water and land resources, and innovative processes in livestock production. It also aims at providing inputs to decision making processes and encouraging the transfer of relevant know-how, technologies and expertise to different countries where similar agro-climatic conditions may exist; thus saving precious resources and promoting sustainable agricultural development as a relevant approach to tackle the food security challenge. Finally, this book focuses on the paradigmatic and policy dimensions and call for an innovative approach by analyzing the key themes in a complex and interrelated manner.
Download or read book The Perception of and Adaptation to Climate Change in Africa written by David Maddison and published by World Bank Publications. This book was released on 2007 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The objective of this paper is to determine the ability of farmers in Africa to detect climate change, and to ascertain how they have adapted to whatever climate change they believe has occurred. The paper also asks farmers whether they perceive any barriers to adaptation and attempts to determine the characteristics of those farmers who, despite claiming to have witnessed climate change, have not yet responded to it. The study is based on a large-scale survey of agriculturalists in 11 African countries. The survey reveals that significant numbers of farmers believe that temperatures have already increased and that precipitation has declined. Those with the greatest experience of farming are more likely to notice climate change. Further, neighboring farmers tell a consistent story. There are important differences in the propensity of farmers living in different locations to adapt and there may be institutional impediments to adaptation in some countries. Although large numbers of farmers perceive no barriers to adaptation, those that do perceive them tend to cite their poverty and inability to borrow. Few if any farmers mentioned lack of appropriate seed, security of tenure, or market accessibility as problems. Those farmers who perceive climate change but fail to respond may require particular incentives or assistance to do what is ultimately in their own best interests. Although experienced farmers are more likely to perceive climate change, it is educated farmers who are more likely to respond by making at least one adaptation.

This book was released on 2013-04-04 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: While there is growing evidence of the impact of targeted subsidies on private input demand, as far as we are aware no empirical studies have examined the spillover effects of targeted subsidies for just one input on the use of other complementary inputs with which there is low substitutability. Consequently, this study begins to fill this gap by exploring the effect of increasing access to subsidized fertilizer on farmers use of improved seed in Nigeria.

Download or read book Climate Change Impact and Adaptation in Agricultural Systems written by Jurg Fuhrer and published by CABI. This book was released on 2014-06-18 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: The focus of this book is future global climate change and its implications for agricultural systems which are the main sources of agricultural goods and services provided to society. These systems are either based on crop or livestock production, or on combinations of the two, with characteristics that differ between regions and between levels of management intensity. In turn, they also differ in their sensitivity to projected future changes in climate, and improvements to increase climate-resilience need to be tailored to the specific needs of each system. The book will bring together a series of chapters that provide scientific insights to possible implications of projected climate changes for different important types of crop and livestock systems, and a discussion of options for adaptive and mitigative management.
