Cassava genetic transformation capacity is still mostly restricted to advanced laboratories in the USA, Europe and China; and its implementation and maintenance in African laboratories has remained scarce. The impact of transgenic technologies for genetic improvement of cassava will depend largely on the transfer of such capabilities to researchers in Africa, where cassava has an important soci...

The US regulations for production of organic milk include a strict prohibition against the use of antimicrobials and other synthetic substances. The effect of these regulations on dairy animal health has not been previously reported. The objective of this study was to characterize disease detection and identify risk factors for selected diseases on organic (ORG) and similarly sized conventional...

the purpose of this study was to survey impacts of drought on socio-economic conditions of guilan paddy farmers. besides recognizing these impacts, it ranked them according to the viewpoint of the paddy farmers. it was of the descriptive- correlation type. questionnaire was the main tool of this study. to determine the validity of questionnaire used of comments of panel experts and reliability ...

This research sought to link Andean soil knowledge and farmer categorization of soil fertility to soil science characterization of soils, and use these to understand the impacts of phosphorus (P) fertilization of legumes using rock phosphate and soluble P fertilizer in 17 smallholder-managed sites with varying soil properties. We found that farmer high/low categorization of soils corresponded t...

(eds M.C.S. Wopereis et al.) 355 and innovation, and ways to build upon these processes or to integrate them with scientific technology development. Farmer technologies, such as farmer varieties, are the result of long innovation trajectories. These trajectories are shaped by interactions among agroecological, socio-economic and cultural factors and it is therefore essential to understand such ...

This article discusses ethical issues raised by automation systems in animal farming. These systems automatically collect various kinds of information about an animal and allow the farmer to monitor it remotely. It is argued that the relationship between the farmer and the individual animal is becoming increasingly distant and impoverished. Although this may protect the animal from some negativ...

South African agriculture is comprised of mainly two categories of farmers -the subsistence farmers in the former homeland areas and the large-scale commercial (mainly white) farmers. This is in contrast with the situation in many other countries in the world where one would find a whole range of farm sizes, ranging from the very small or subsistence farmer to the very large farmer/agribusiness...

The aim of this research is to develop a farmer prediction system to identify crop suitable for particular soil. To achieve this Neural Network should be trained to perform correct prediction for farmers. After the network has been properly trained, it can be used to identify the crop suitable for particular type of soil. The Artificial neural networks are relatively crude electronic networks o...

For several decades the effective and efficient dissemination of new agricultural knowledge among farmers in developing countries has been problematic. Two major programs were implemented in Indonesia, namely The Training and Visit (T&V) Extension Program or The Massive Guidance (BIMAS) Program, from the mid 1960s until the end of the1980s, and the Farmer Field School (FFS) Program, during the ...
