One of the wood industry activities in forestry sector is Eucalyptus sp at PT.Riau Mainstay Pulp and Paper Riau Province. The production process used for pulpand has many factors its productivity. them planting with weedcontrol problems, which use herbicide active ingredient glyphosate. glyphosate not effective against all types weeds. Therefore, it necessary to know right combination weed cont...
A key enabling factor for treating individualized weeds in the crops is Automatic Weeding Control device (AWCd) as it being capable of finding and distinguishing field. The non-herbicide approaches used to manage are a component personalized treatment weed crops. In this study, mechanical control techniques investigated an alternative. three specifications—a cutting mechanism, head-surface till...
A field experiment was conducted during the seasons of 2010/2011 in a semiarid savannah zone, at the faculty of agriculture demonstration farm University of Zalingei two kilometers east of Zalingei town Western Darfur State. The aim of the experiment is to study the effect of weed control on growth and seed production of (Clitoria ternatea) under rainfed conditions. Four treatments viz.; No wee...
Mechanical weed control has become a more efficient and economical method over the past few years. This study presents concept of an e-power source weeding mechanism to carry out operations in crop rows with spacing 30 cm. An e-powered mechanical inter-row weeder was designed, developed, evaluated for sandy loam soil conditions. The result indicates that speed operation drum diameter significan...
In this paper, an electro-mechanical integrated weed management system was designed, constructed, and tested. This laboratory-scale solution elements of machine vision, controls, mechanical actuation to selectively remove weeds from within a crop row. The device validated in controlled environment using corn crops. Various conditions were considered ensure the robustness design. Though some des...
The main requisite for weeding-thinning machine is the location of the main stem of the crop. In this study, crops and their positions were detected using image processing techniques with the aid of artificial neural networks. Morphological operations were performed to singulate different objects in the images. Several shape features were fed to artificial neural network to discriminate between...
Aim of study: To test new approaches to perform mechanical weeding inside the row in horticulture and tree fruit fields. The idea is weed by skipping crop means a rotating system instead traditional crosswise one. Area North Italy. Material methods: Numerical models have been developed simulate over time generating numerical maps quantify different kind worked areas. Main results: Considering e...
Weed control is necessary to ensure a high crop yield with good quality. Herbicide application and mechanical weeding are the most common methods worldwide. The use of herbicides has led increasing occurrence herbicide-resistant weeds unwanted contamination environment. Mechanical weed harms beneficial organisms, increases degradation organic matter, may dry out soil, stimulate new cohorts seed...
to assess the effect of non chemical management of weed control on forage sorghum (sorghum bicolor) a field study was conducted in varamin, iran during 2010 crop year in a three- replicated- split factorial experiment laid out in randomized complete block design with four weeding levels (w1= one time cultivation at 3-leaf stage using a duck foot cultivator, w2= two times cultivation at 3 and 5-...
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...
