The use of plantations to manage extensive tracks of deforested lands in the tropics is a conservation strategy that has recently received considerable attention. Plantation trees can promote seed dispersal by attracting dispersers and creating favorable site conditions, leading to increased germination and establishment of indigenous trees. Subsequently, plantation trees can be harvested for p...

A flexible high-level control language is an important element in the continued task of introducing mobile agents to new application domains. One such new application domain is the use of a small mobile agent in a agricultural row crop field performing intra-row weeding. This paper defines requirements and scope of a process and behaviour based scripting language needed to control the weeding a...

Current approaches to topdressing and weeding operations for rice cultivation present several disadvantages, such as poor precision, low efficiency, serious environmental pollution, so on. This paper presents a row-controlled fertilizing–weeding machine improve the precision of fertilizing reduce heavy pollution associated with cultivation. A proportional–integral–derivative algorithm was adopt...

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...

in order to study the sowing system, row distance and weeding effect on yield and yield components of intercropped maize with peanut, this experiment was conducted, as factorial based on a rcbd with three replications at the research farm of agriculture center of zabol university (iran) during growing season 2011- 2012. sowing system were four levels including sole maize, sole peanut, 50% maize...

During the course of science education one of the recognizable and desirable changes from a novice to an expert is in their language (knowledge representation). One noticeable change is that of weeding out ambiguous expressions bringing in clarity and rigor. However, this happens not by weeding out the concept names but by choosing more and more accurate linking words (relation names). By focus...

Agricultural robots have the potential to reduce herbicide use in agriculture and horticulture through autonomous precision weeding. One of the main challenges is how to efficiently plan paths for a robot arm such that many individual weeds can be processed quickly. This paper considers an abstract weeding task among obstacles and proposes an efficient online path planning algorithm for an indu...
