PREMISE OF THE STUDY Archaeological and genetic analyses of seed-propagated annual crops have greatly advanced our understanding of plant domestication and evolution. Comparatively little is known about perennial plant domestication, a relevant topic for understanding how genes and genomes evolve in long-lived species, and how perennials respond to selection pressures operating on a relatively ...

Cover crops (CC) provide important ecosystem services that are demanded to achieve more sustainable agrosystems. However, the legacy effects of CC on microbial community structure and its interactions with subsequent cash (CaC) still poorly understood, especially when mixtures involved. In this work, five (3 monocultures 2 mixtures) were selected in an experiment under semi-controlled condition...

Coexistence between genetically modified (GM) and non-GM plants is a field of rapid development and considerable controversy. In crops, it is increasingly important to understand and predict the GM volunteer emergence in subsequent non-GM crops. Theoretical models suggest recruitment from the seedbank over extended periods, but empirical evidence matching these predictions has been scarce. Here...

[1] Accurate estimation of spatially distributed chlorophyll content (Chl) in crops is of great importance for regional and global studies of carbon balance and responses to fertilizer (e.g., nitrogen) application. In this paper a recently developed conceptual model was applied for remotely estimating Chl in maize and soybean canopies. We tuned the spectral regions to be included in the model, ...

World population has already exceeded 6.5 billion, out of which about 850 million (13 percent) are undernourished. With the current growth rate, the world community faces even a greater challenge of hunger and food security as the estimated the population will catch 9 billion by the year 2050 with doubled needs for food. At the same time, preservation of biodiversity, stopping deforestation and...

European Union (EU) policies regarding genetically modified (GM) crops and food have increasingly isolated its member states from much of the rest of the world in this regard over the past decade. The discussion in European countries over whether to grow and eat GM crops and food has stalled plant research, while the rest of the world has been growing and using an increasing number of GM pestor...

The digital model of the laboratory bench parts of digging deep rootstalk crops were established through adopting the parametric model technology based on feature. The virtual assembly of the laboratory bench of digging deep rootstalk crops was done and the digital model of the laboratory bench parts of digging deep rootstalk crops was gained. The vibrospade, which is the key part of the labora...

On the basis of adequate understanding the significance of virtual crops research, according to the research state and characteristics of virtual crops’ typical modeling methods at home and abroad, a new modeling thoughtway of virtual crops system was put forward based on Agent technology. This method established crops self-learning system based on neural network. It is helpful to understand cr...

The environmental, social and economic consequences of the use of fossil fuels has led to the search for new energy resources, such as energy crops which are expected to contribute in alleviating energy problem while they can lead to the diversification of the agricultural production. This research work investigates the acceptance of energy crops in the Larissa regional unit using questionnaire...

The share of single species was expressed for the weed flora in the Podravina region, North Croatia. The analysis was based on standard phytosociological records according to Braun-Blanquet. Different types of crops were included, both row crops (maize, sugar beet, potato, vine, sunflower) and dense cereals such as wheat and barley. An analysis of 552 records was made, to find quantitative rela...
