Abstract In southern China, the eucalyptus plantation industry has been severely restricted by government policy over concerns on negative environmental impacts. its place, large-scale plantations of high-value tropical tree species such as nitrogen-fixing Dalbergia odorifera and hemiparasite Santalum album have widely cultivated including in mixed-species plantations. However, despite their po...

in order to evaluate the effect of nitrogen rate and weeding time on weed communities dynamic, a field study conducted in a research farm of chamran university, ahwaz. the experimental design was split plot based on rcb with three replications. nitrogen rates (77, 110, 143 kg/ha) were considered in the main plot and time of weeding (at 5, 8, 11, leaf stage with control and weedy plot) as sub pl...

to determine the optimum weed management method and plant population density on chickpea yield, a split plot experiment based on rcbd with four replications was carried out at the university of tehran research farm (located in karaj) during 2010-2011. the main factor consisted of nine treatments including: 1. trifluralin pre-plant, 2. pendimethalin pre-plant, 3. complete weeding, 4. imazethapyr...

Information fusion has a potential applicability to a multitude of different applications. Still, the JDL model is mostly used to describe defense applications. This paper describes the information fusion process for a robot removing weed in a field. We analyze the robotic system by relating it to the JDL model functions. The civilian application we consider here has some properties which diffe...

An important challenge in the analysis of mechanochemical coupling in molecular motors is to identify residues that dictate the tight coupling between the chemical site and distant structural rearrangements. In this work, a systematic attempt is made to tackle this issue for the conventional myosin. By judiciously combining a range of computational techniques with different approximations and s...

Peanut (Arachis hypogaea L.) yield and financial return can be negatively affected by weeds the combination of early leaf spot disease [ Passalora arachidicola (Hori) U. Braun] late Nothopassalora personata (Berk. & M.A. Curtis) Braun, C. Nakash., Videira Crous] in Ghana. Research was conducted southern Ghana to evaluate hand-weeding, herbicide applied preemergence (PRE) or postemergence (P...

Weeding is the most difficult process in field of agriculture, which may consume more manpower, time and money. This paper designed for detecting out weeds in-between crops drilling them using blade attached at end robotic. Though this robot works autonomously, does not require manpower. It offers reduced working requires less installation cost. Insufficient labour, improper weeding, pandemic s...
