Conservation agriculture (CA) is based on minimum soil disturbance, permanent soil cover,
and crop rotation; it is promoted as a sustainable alternative to systems involving …

Tillage has been known to cause soil erosion and cost time and resources and this affects
productivity and inflates the cost of production. Therefore, over the past few years in many …

Weeds are major constraints on crop production, yet as part of the primary producers within
farming systems, they may be important components of the agroecosystem. Using published …

ABSTRACT Glyphosate [N‐(phosphonomethyl) glycine]‐resistant crops (GRCs), canola
(Brassica napus L.), cotton (Gossypium hirsutum L.), maize (Zea mays L.), and soybean …

Macronutrient inputs to annual crop** systems can benefit weeds as well as crops,
sometimes decreasing or eliminating the benefits of fertilization. This interaction between …

Agricultural weeds evolve in response to crop cultivation. Nevertheless, the central
importance of evolutionary ecology for understanding weed invasion, persistence and …

The term 'cover crops' will be used in this chapter as a general term to encompass a wide
range of plants that are grown for various ecological benefits other than as a cash crop. They …

The development of integrated weed management programs requires a clear understanding
of the factors and mechanisms conditioning weed community dynamics in agroecosystems …

Physical, cultural and biological methods for weed control have developed largely
independently and are often concerned with weed control in different systems: physical and …

In a 6-yr study on four farms (36 fields) in Ontario, Canada, we tested the effects of tillage
(moldboard, chisel plow, no tillage) and crop rotations (continuous corn, corn-soybean, corn …
