| Ghana is self-sufficient in the production of maize, the major staple food for many low-income Ghanaians, yet staple maize-availability projections in Ghana do not include insecurity problems in the post-harvest season caused by poor storage, distribution difficulties, and high prices. This study uses the concept of food "security-storage" relationships or an "availability-gap" to refer to the ability of poor Ghanaians to access stored maize in the post-harvest season. This estimated "availability-gap" measures available maize needed to raise food consumption of the poorest Ghanaians to the minimum nutritional requirement... |

| Intercropped crops represent an important production system in organic farming, especially maize/climbing bean mixture due to its high content of protein in bean seeds for human diet, and producing silage for ruminants. To test this hypothesis, the effects of maize (Zea mays L.) sown as a sole crop and maize/climbing bean (Phaseolus vulgaris L. cv. Cipro) mixtures on maize plant height, maize leaf area index, bean leaf area index and grain yield were investigated in field experiments on an organic farm following accepted rules of certification.

| Maize cultivation provides a valuable addition to the feed ration in farms with dairy cows. However, the cultivation of organic maize is challenging and posing risks regarding erosion, leaching of nutrients and soil compaction. Not all sites are suitable for maize cultivation. Therefore, it is important to first study the site before the cultivation. This leaflet provides some general information on how to cultivate organic maize optimally. Different topics about the needs of maize, the sowing, the right crop rotation and pest management are covered. Finally, there is also some... |

| The successful development and diffusion of improved maize seed in Zambia during the 1970s–80s was a major achievement of African agriculture but was predicated on a government commitment to parastatal grain and seed marketing, the provision of services to maize growers, and a pan-territorial pricing scheme that was fiscally unsustainable. Declining maize output when this system was dismantled contributed to the reinstatement in 2002 of subsidies for maize seed and fertilizer through the Fertilizer and Farmer Input Support Programs (FISP). In the meantime, seed liberalization has led to an array of new, improved |

| This study is an evaluation of Thailand's maize export agreement policy through economic analyses of prices and markets for Thai maize. Maize export agreements between Thailand and Japan since 1966 and recently Taiwan has played an important role to the overall development of Thai maize. These agreements feature two important policy elements, (a) an export quota and (b) a fixed export price. Some disagreements now exist, however, as to whether these export agreements are more or less desirable for Thailand than free trade. Statistical analyses of the wholesale-export price linkages of |

| This is one of a series of seven in-depth country studies on maize production systems in Asia, funded by the International Maize and Wheat Improvement Center (CIMMYT) and the International Fund for Agricultural Development (IFAD). It is part of a project designed to promote sustainable intensification of maize production systems while ensuring equitable income growth and improved food security, especially for poor households that depend on maize. Maize is one of five major crops grown in the uplands of Thailand, along with rice, cassava, sugar cane, and rubber trees. Government-promoted... |

| This book examines future technological and policy prospects for the sustainable intensification of rainfed upland maize production in Asia, and derives R&D priorities for specific maize production environments and markets. Village-level and farmer-group surveys were conducted to characterize upland maize production environments and systems in China, India, Indonesia, Nepal, the Philippines, Thailand, and Vietnam. Survey findings, particularly farmer-identified constraints to maize production, complemented with other relevant data, were used in country-level, R&D priority-setting workshops. High on the list of... |

| The objective of the study was to provide empirical evidence on whether food aid leads to depressed domestic maize prices and reduced maize production in subsequent years in Swaziland. The lack of empirical evidence has often resulted in premature negative conclusions about the impact of food aid on Swaziland’s maize industry. The study used secondary national data from 1985 to 2006. Variables used in the statistical analysis included quantity of cereal food aid; quantity of commercial maize imports; quantity of locally produced maize; official maize... |

| Maize, the second most globally important staple crop after wheat, originated in Mexico, where it is typically grown as part of a set of associated crops and practices called the milpa system. This ancient mode of production is practiced today in ways that vary by cultural context and agro-environment. Milpas generate private economic value, in terms of food security, diet quality and livelihoods, for the two-million farm households who manage them. Furthermore, milpas generate public economic value by conserving agrobiodiversity, especially that of maize landraces, which have the potential to contribute unique traits needed by plant breeders for future crop improvement. In this way,... |

| Responding to demand from expanding poultry feed markets, maize area in Bangladesh rose from only a few thousand hectares in the 1980s to more than 200,000 hectares in 2007-08. This publication describes the rise of maize in Bangladesh, emerging problems or risks, technology options for rice-maize systems, and future research and development needs. It also outlines the role of CIMMYT, through its Bangladesh office, in the establishment and promotion of maize, as well as the provision of germplasm and capacity building for researchers and farmers, in collaboration with the Bangladesh Agricultural Research Institute (BARI),... |

| The debate about co-existence usually focuses on the situation of neighbouring farms. Organic producers take the position that co-existence affects the whole supply chain. Therefore, this paper compares the maize grain supply chains in Switzerland and Spain in order to identify which factors influence the segregation of genetically modified (GM) maize from non-GM maize, and discusses how organic production copes with the challenge of GM maize. Considerable differences exist between Spain and Switzerland with regard to grain maize as a component of animal feed. In Spain, where GM |

| The researches was oriented towards studying the productivity and land equivalent ratio of maize and bean in intercropping, in two spatial arrangements, in the ecological agriculture conditions. The experiment was carried out in Moara Domnească Experimental Field, on redish preluvosoil, in randomised blocks in 4 replications. It was sown an simple, early maize hybrid (Zea mays - DK 391) and bean (Phaseolus vulgaris – Diva variety). Maize was sown at 70 cm between rows and 28,6 cm between plants per row, at a density of 5 plants/m2. Bean was sown between maize plants at a density of 4 plants/m2 and between |

| ABSTRACT This study aimed at evaluating the physiology of maize and weeds when living under different densities. The randomized block design with 4 replications was used. The factorial scheme 5 x 2 + 1 and 5 x 3 was adopted, for maize and weeds respectively, corresponding to weed species (Bidens pilosa, Commelina benghalensis, Urochloa brizantha, Sorghum arundinaceum and Ipomoea triloba) and infestation density (control, 15 and 30 plants m-2). Weeds were kept in coexistence with the maize hybrid DKB 390 PRO 2, with an additional treatment for maize plants absent of competition. It was kept in coexistence with |
