Mechanical weed control in onion seed production

Crop Protection, 2020
Abstract Two field experiments with onion (Allium cepa L.) cultivated by the “seed-to-seed” and “bulb-to-seed” methods for the organic seed production were carried out in central Italy in order to evaluate the effects of some mechanical methods (harrowing, hoeing, hoeing-ridging, split-hoeing, finger-weeding, manual weeding) on: i) weed control; ii ...

Mechanical Weed Control

2009
The aim of this chapter is to highlight and focus on novel and promising developments in soil-engaging intra-row hoeing. Conventional weeding tools for intra-row treatments based on selectivity are limited in control efficacy. Four intra-row weeders based on computer-controlled soil-engaging tools are described. They all rely on input information about

Mechanical Weed Control in Agriculture

2001
Weeds are plants that are considered undesirable in a crop at a given time.Weeds are harmful for a number of reasons. They reduce crop yields, interfere with the harvest, support pathogens and insect pests and contaminate seeds.

Barley seed vigour and mechanical weed control

Weed Research, 2000
Two field experiments investigated the influences of crop seed vigour on the effect of weed harrowing and crop:weed interactions in spring barley. Artificially reduced seed vigour, which was similar to the variation within commercial seed lots, caused a reduction in germination rate, delayed time of emergence and, consequently, caused reduced ...

Intra-row mechanical weed control—possibilities and problems

Soil and Tillage Research, 1997
Abstract For five years, graduate students of the Tillage Laboratory of Wageningen Agricultural University studied the effectiveness of intra-row weed control by brushes, tactile hoes and weeder harrows in combination with a drill planting system and paper pots.

Possibilities of mechanical post-emergence weed control in sugar beet

Soil and Tillage Research, 1991
Abstract During a period of four years, 1986–1989, a number of field experiments on post-emergence weed control in sugar beet was carried out. The experiments are components of five weed control systems: chemical; integrated; integrated including ridging; mechanical; mechanical with plants in squares.

Evaluation of mechanical weed control in legume crops

Crop Protection, 2018
Abstract Two three-year field experiments with soya bean (Glycine max (L.) Merr.) and faba bean (Vicia faba L., var. minor Beck.) were carried out in central Italy in order to evaluate the effects of different mechanical methods (spring-tine harrowing, hoeing, hoeing-ridging, split-hoeing, finger-weeding) on weed control and crop yield. Split-hoeing +
