The need for herbicide usage reduction and the increased interest in mechanical weed control has prompted greater attention to development of agricultural robots autonomous weeding past years. This also requires suitable tools. Therefore, we devised a new tool perform intrarow sugar beets. A conventional finger weeder was modified equipped with an electric motor. allowed rotational movement wee...

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<...

the actual mechanics of performing this activity vary widely and is the cause of much concern in libraries. Furthermore, the actual decision process for selecting an item to be culled from the primary collection is not fixed, and varies according to the type of library under study and/or to the mandate of the library. Thus, the approach to weeding taken by a small public library has an outcome ...

Wheat crop is inhabited by several monocot and dicot weeds which have posed a major problem in wheat production. These not only reduce the quality quantity of produce but also increase cost There management therefore becomes crucial with help proper combination herbicides considering bottlenecks mechanical methods. Thus, field experiment was conducted Rabi season 2016-2017 at research farm Depa...

farmers are now more interested in application of weed control methods and tools with less environmental side effects. flame weeding using propane gas is an approach with almost no any chemical residue on the soil and plant surfaces or underground water. in this research, a flame weeding machine with the ability of uniform and also discrete flaming was developed and evaluated in laboratory and ...

in order to examine of the weed damage on corn and determination of the most suitable index for corn (zea mays l.) yield reduction in field condition and multi-species weed competition, an experiment as an interval mapping was carried out in the researching field of mashhad university during 2008-2009. treatments were complete control (pre-planting treflan and hand weeding), no control (no herb...
