Silvopasture practices are being advocated as a means of maintaining pine forest acreage in the southeast United States; however, scientific data on the design and management for optimum tree growth are lacking. Studies were conducted near Booneville AR to determine the effects of weed control, irrigation, soil fertilization and protection from cattle grazing on the establishment of loblolly pi...

A field experiment was conducted at the Pulse Research Centre of Bangladesh Agricultural Research Institute, Ishurdi, Pabna during Kharif-II season of 2010 to evaluate the efficacy of five herbicides for controlling weeds associated with mungbean (BARI Mung-6). The five herbicides such were: Paraxon (27.6% WV Paraquat dichloride salt), M-clor 5G (Butaclor), Topstar 40 WP (40% Oxadiargyl), Hamme...

Small size agricultural robots which are capable of sensing and manipulating the field environment are a promising approach towards more ecological, sustainable and human-friendly agriculture. This chapter proposes a machine vision approach for plant classification in the field and discusses its possible application in the context of robot based precision agriculture. The challenges of machine ...

Japanese honeysuckle is rapidly increasing as a weed throughout most of the North Island and northern South Island of New Zealand. A classical biological control programme was initiated in 2004–2005 with a survey of the natural invertebrate fauna and pathogens associated with the weed in New Zealand. The honeysuckle was being attacked by a diverse range of native and introduced invertebrates. B...

135 ABSTRACT: Heavy metals and dyes are major contributors in contamination of water streams. These contaminants enter into our ecosystem, thus posing a significant threat to public health, ecological equilibrium and environment. Thus a combined discharge of these contaminants results in water pollution with high chemical oxygen demand, biological oxygen demand, color, particulate matter, suspe...

This paper analyzes optimal weed control management strategies under static and dynamic decision rules. Seed bank is taken into account to introduce dynamics into the model. We present a numerical example of controlling Sheathed Monochoria (Monochoria Vaginalis) in Korean rice paddy fields. Our results show that producers benefit from dynamic decision rules; higher income and more control of we...

We report 2 cases of teenagers who were poisoned with Jimson weed (Datura stramonium) and presented to the emergency department with a severe acute anticholinergic toxidrome after ingestion of several hundred seeds. The patients presented with visual hallucinations, disorientation, incomprehensible and nonsensical speech, and dilated sluggish pupils. Both patients required restraints for combat...

Broadcasting antenna array null filling is a very challenging problem for antenna design optimization. This paper compares five antenna design optimization algorithms (Differential Evolution, Particle Swarm, Taguchi, Invasive Weed, Adaptive Invasive Weed) as solutions to the antenna array null filling problem. The algorithms compared are evolutionary algorithms which use mechanisms inspired by ...

Discrete sampling data is used in several environmental studies to create maps in order to support decision-making processes. The decision maps represent an increasing importance in modern Precision Farming. For the application of herbicides in a field, maps of weed distribution are necessary. The uncertainty of those, resulting from sparse sampling patterns is one major reason why farmers tend...
