Data from a survey of County Agricultural Extension Agents and the Census of Agriculture were use to develop logit regression models to estimate the probabilities of farmers adopting four precision farming technologies in Tennessee counties. County characteristics associated with adoption were owned versus rented land, land in large farms relative to total land in farms, the value of crop sales...
Mixed farming systems involving varying degrees of crop–livestock integration are found in many parts of Sub-Saharan Africa. Increasing population combined with climatic, economic, social, and institutional changes are transforming systems for producing crops and livestock—from systems based on extensive, shifting cultivation and grazing to ones that are more intensively managed and are based o...
The conventional 'Neolithic package' comprised animals and plants originally domesticated in the Near East. As farming spread on a generally northwest trajectory across Europe, early pastoralists would have been faced with the challenge of making farming viable in regions in which the organisms were poorly adapted to providing optimal yields or even surviving. Hence, it has long been debated wh...
the present study was conducted to investigate qualitative and quantitative aspects of irrigated wheat production in three major farming systems i.e. peasant, commercial and cooperative systems in kordestan province. accordingly, seven basic hypotheses were tested. the data were drawn from individual interviews with 360 farmers who planted wheat in 2004-2005. the sample was selected using multi...
Johne’s disease (JD) is a chronic, production-limiting disease of ruminants. Control programs aiming to minimize the effects of the disease on the dairy industry have been launched in many countries, including Canada. Those programs commonly focus on strict hygiene and management improvement, often combined with various testing methods. Concurrently, organic dairy farming has been increasing in...
Ahmad K. (2014): Molecular farming: strategies, expression systems and bio-safety considerations. Czech J. Genet. Plant Breed., 50: 1–10. Molecular farming is an experimental application of biotechnology that involves the genetic modification of crops for the production of proteins and chemicals for medicinal and commercial purposes. The vast majority in the developing world cannot afford the h...
The present practice of traditional slash-and-burn agriculture (locally called jhum kheti) by the ethnic Noctes in Tirap district of Arunachal Pradesh, India is a part of history of rural landscapes. Even today, the local jhumias totally depends on this traditional farming system for their livelihood. Nonetheless, it is time and again considered as ‘traditional’ and firm in contrast to modern m...
The concept of organic farming is summarised and compared as an example to farming with biotechnology-derived crops. If done within an ecological concept, both methods can be seen as environmentally acceptable. Organic farming does not offer consistent arguments for the rejection of transgenic crops. Some arguments (from genomics to biodiversity) are discussed in order to demonstrate that the c...
Farming systems for pest control, based on the stimulo-deterrent diversionary strategy or push-pull system, have become an important target for sustainable intensification of food production. A prominent example is push-pull developed in sub-Saharan Africa using a combination of companion plants delivering semiochemicals, as plant secondary metabolites, for smallholder farming cereal production...
Studies on sustainable agricultural have not paid adequate attention to farmers' behaviour regarding sustainability. The objectives of this research were: 1) to determine the relationship between socio-economic and farming factors with “sustainable agricultural knowledge”, 2) to predict “sustainable agricultural knowledge” based on socio-economic and farming factors, and 3) to determine the rel...
