This paper investigates regional and international integration of maize markets in Zambia to test wether the liberalization policy has led to internally and externally integrated food markets. The results indicate that regional maize markets

Agricultural climatology;Agroclimatology ; China ; Drought ; Irrigation ; Maize;Corn ; Precipitation ; Soil moisture ; Water resources ; Wheat
Winter wheat and summer maize are two important crops in the Heilonggang area which is the driest part of the North China Plain. The thermal-light conditions are satisfactory for double cropping of winter wheat-summer maize, but rainfall
is deficient for two crops. Wheat production in this area should be restricted to a scale which is suitable to water resources conditions, while maize production can be further developed.
Changes in climatic variability and maize yield in Northeast China
Agroclimatology ; Atmospheric circulation ; China ; Climatic variability ; Crop ; Maize ; Model ; Stochastic model
A dynamic simulation model for maize growth and development, MZMOD, was used to assess the potential implication of the changes in both climatic means and variability, and the impacts of crop management in changing climate on maize production
in Northeast China. The impacts of the diverse distributions of climatic factors determined by multiple changes in climatic variability on maize production and its variation, however, are not identical and have distinct regional disparities.
This paper discusses a study of household land-use and livelihood strategies in the Toluca Metropolitan Area, west of Mexico City, a traditional maize-growing region that has experienced rapid urban growth. It shows that maize is being abandoned
to some extent as producers age and non-farm income sources surge. At the same time, some maize still persists for tradition and security as non-farm income is often volatile. The results reflect a persistence of maize in peri-urban areas of central Mexico
Die Ausweitung des Maisanbaus in Oberschwaben. Ursachen, Auswirkungen, Aussichten The spread of maize cultivation in Oberschwaben. Causes, effects, prospects
During the last 15 years the per-acre area on which maize has been grown in Oberschwaben has increased from 428 ha (hectares) in 1960 to 17680 ha in 1974. A comparaison of two neighbouring villages has shown that farmers who are younger and better
trained on larger farms and who are breeding a greater number of cattle in modernized cowsheds grow more maize. In this region as well as in the Allgäu around Wangen the spread of maize cultivation in terms of the principles of an innovation process were
clearly observable. While the figures for per-hectare cultivation of maize to be used as grain have slightly decreased since 1971, it is to be expected that the perhectare area of maize for storage in silos will increase during the next years. (HSC).
A természeti adottsagok és a fajta szerepe Békés megye kukoricatermesztésében. (The role of natural endowments and the species in maize-growing in Békés county)
The paper confronts the ecological requirements of maize with the natural endowments of Békés county. (CK).
A kukorica optimalis termszetési korzeteinek meghatarozasa természeti tényezok alapjan. (Determination of optimal maize-growing regions on the basis of natural factors)
The development of agriculture is inconceivable without the knowledge of the factors affecting the agricultural production and without analyzing their territorial dissimilarities. Farming in general and maize-growing in particular are most directly
Der Innovationsprozess des Maisanbaus in Baden-Württemberg Maize cultivation in Baden-Württemberg as a process of innovation
The spread of maize cultivation has shown all the characteristic features of an innovation process: it has been initiated by one group of farmers with a distinctive feature matrix of its own. Strating point has been the southern part of the Upper
Study on micro-water-collecting technique in dryland field of spring maize

Based on the cross-entropy theory, a spatial production allocation model (SPAM) has been developed for presenting spatio-temporal dynamics of maize cropping system in Northeast China during 1980–2010, at the pixel level. The AA. further explored
spatio-temporal variations of maize with latitude, longitude, and elevation. Discussion of the results. It is highlighted that maize planting density increased gradually to a moderately high level over the investigated period, which reflected the trend
of aggregation of maize cultivation driven by market demand.
Minimal cost transport of agricultural products between Malawi, Zambia and Zimbabwe. Results from a case study of intra-regional trade in maize
