in order to investigate chemical control of weeds in nursery of orange coneflower and moss rose two experiments were conducted in randomized complete block design (rcbd) with four replications in 2011. treatments were per-plant trifluralin (ec48 percent) with and without incorporation with soil at 0.2 and 0.3 ml/m2, per-emergence and post-emergence oxyfluorfen (ec24 percent) at 0.2 and 0.3 ml/m...

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...

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...
