Innovative technical equipment for weed control in leguminous crops

Weed Control with Cover Crops in Irrigated Potatoes

Field experiments at Oakes, ND, USA in 2010 and Carrington, ND, USA in 2011 were conducted to evaluate the potential for cover crops grown in the Northern Great Plains, USA in order to reduce weed emergence and density in irrigated potatoes. Treatments included five cover crop treatments and three cover crop termination treatments. Termination of cover crops was done with glyphosate, disk-till,...

Hierarchical Hybrid Control for Innovative Air-conditioning Equipment

This paper describes the control system for innovative air-conditioning equipment, in particular an air treatment unit. The most important characteristic of the equipment is to be “friend of the environment”, in the sense that it does not use environmentally aggressive refrigerating fluids. Other main characteristic is associated with the complexity of its control, due to the large number of in...

Winter Cover Crops and Vinegar for Early-Season Weed Control in Sustainable Cotton

Weeds may be suppressed by winter cover crops and the use of organic herbicides such as vinegar. Black oat (Avena strigosa) and hairy vetch (Vicia villosa) winter cover crops were planted for 2 years as part of a sustainable production system for cotton in the Lower Rio Grande Valley of Texas, and were till-killed each spring prior to cotton planting. Palmer amaranth (Amaranthus palmeri), commo...

An Ultrasonic System for Weed Detection in Cereal Crops

Site-specific weed management requires sensing of the actual weed infestation levels in agricultural fields to adapt the management accordingly. However, sophisticated sensor systems are not yet in wider practical use, since they are not easily available for the farmers and their handling as well as the management practice requires additional efforts. A new sensor-based weed detection method is...
