The aim of the study was to determine the biomass, abundance and species composition ofweeds, as well as macroelement uptake in potato weeded using mechanical, mechanical–chemical and mechanical control combined with the sowing of living mulches of white mustard,common vetch, Persian clover and tansy phacelia. Abundance and biomass of the weeds was themost effectively limited by the mechanical ...

Weeding or deselection of materials has become an integral part of library management. Based on a nineteen-question survey about weeding practices in public libraries, this article discusses the personal perspectives of public librarians on weeding as well as the weeding practices of their institutions. The three most common criteria for weeding are circulation, physical condition, and accuracy...

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 an agricultural field performing mechanical intra-row weeding. This paper defines requirements and scope of a process and behaviour based scripting language needed to control the weedin...

Mechanical-chemical synergy has been proven efficient in weed control. However, characterizing the state of weed–soil complex after mechanical weeding and revealing its effects on subsequent herbicide application is still challenging, which restricts implementation this technology. This paper first presents a method to characterize from perspectives fragmentation composite characteristics. The ...

Scope The autonomous navigation in agricultural environments allows also to carry out autonomous operations of special interest in agriculture environments. The goal of an autonomous navigation is to cover all the required areas where the operation has to be made. We take into account different navigation strategies using proper sensors being also able to detect references which makes possible ...

This paper presents a mechanical control method for precise weeding based on deep learning. Deep convolutional neural network was used to identify and locate weeds. A special modular weeder designed, which can be installed the rear of mobile platform. An inverted pyramid-shaped tool equipped in shovel out weeds without being contaminated by soil. The weed detection implemented an embedded syste...

Weeding is an important time consuming and drudgery prone task mainly performed by hill farm women for almost all crops grown. This directs for interventions in terms of improved technologies (weeder, kutla and hoes) to relieve women from high energy demands, time spent and associated drudgery particularly for weeding activity. The study was conducted in two hill states of India viz. Himachal P...

Field experiments were conducted during the 2010 and 2011 cropping seasons to investigate the effect of farmyard manure and weeding regimes on the growth and yield of okra. The study was a factorial experiment laid out in split plot design, replicated three times. Farm yard manure was assigned as main plot treatments, while weeding regimes was assigned as sub plot treatments. Parameters measure...

in order to evaluate the competitive ability of legume cover crops on interference of weeds in corn, an experiment was carried out in sari agricultural sciences and natural resources university during 2011 growing season. this research was carried out based on complete block design with three replications. treatments consisted of three cover crops including: soybean (glycine max l.), fenugreek ...

One of the most important agriculture operations is to properly manage weeds. Weed management a tedious task. If weeds aren't effectively controlled, it will negatively affect crop output, quality, and harvest costs. To grow successful crop, weed frequently requires significant resource inputs. Review discussion inter-row intra-row mechanical weeding, two different control techniques. In partic...
