If you have too many weeds, they kill the corn. but dont worry about alalfa or hay. they have strong enough roots to handle lots of weeds.
Weeds, Pests, and Diseases.
The yield of ANY crop is affected by weeds. While you can't always see the effects, the weeds are stealing crop nutrients and water from the crop.
the major group of activities for improving crop yields can be classified as : .crop variety improvement .crop production improvement .crop protection management
How do weeds compete for resources?if weeds steal resources from a farmer's crop, do they steal ?the roots of weeds absorb nutrients from the soil,meaning fewer nutrients are available to the crop plants.the roots of weeds absorb water from the soil, so less is available to the crop plants.the leaves of weeds absorb carbon dioxide from the air,so less is available to the crop plants.the leaves of tall weeds can also absorb light before it reaches the crop.
Higher yields = increased income.
The main advantage is the ability to spray for weeds with roundup and not damage the crop. Roundup is a non-selective herbicide that controls both grassy weeds and broad leaf weeds. Roundup ready crops are unaffected by roundup so all weeds can be killed while the crop is undamaged. Basically, a farmer can control all weeds with one herbicide and not have to worry about a loss of the crop.
the weeds could eat you up!
The plow increased crop yields and made soil more porous.
Crop rotation system developed in Britain during agricultural revolution increase crop yields by increasing nutrients in the soil.

A yielder is someone or something which yields a crop, or which yields some other substance.
