The Effect of Weeds on Agriculture
Title of study : Weeds.
Name: Danielle Valere
Teacher’s Name : Mr. Williams.
Date: 11th March 2013.
Introduction.
Weeds are seen as a form of pests to farmers as the interfere with the growth and production of crops. Farmers as a result have to take care of their crops by ensuring that the area that they desire to plant their crop in is fully sanitized and that the area is ready for planting. If this is not done the farmer would be in some serious problems resulting in unfortunate consequences.
In this project we will take a look at what are weeds the major local types , the effects they have on crop production as well as the different methods of weed control.
Thesis Statement :
In this paper we will look at the topic weed, the definition of a weed the local types of weeds , the effects of weeds on crop production and the different methods of weed control .
Definition of a weed : Weed- A weed is a plant that is growing where it is not wanted, it can have strong and healthy growth, and is able to overgrow valued plants by overcrowding, thus depleting soil nutrients and moisture that would otherwise be available to preferred plants.
Major local Types of Weeds .
There are Three types of weeds. The Grassy Weeds , Broadleaf weeds and Sedges. However in Trinidad and Tobago we mainly have Grassy weeds and broadleaf weeds.
Grassy weeds , these weeds are commonly seen in the Caribbean and more so in Trinidad and Tobago.
Some examples of these Grassy Weeds that are seen are :
Crab Grass: Crab grass is eighteen inches tall and twenty inches wide. It usually grows on a lawn, on a landscape or in a garden. Crab grass is a grassy plant that grows as roots anywhere its stems make contact. Alone or in groups, they form a dense mat that smothers any competing weeds or grass.
Creeping Bent Grass : This type of Grass weed is usually seen on a lawn especially in moist ,fertile areas where turf is closely mowed. The blue-green leaves
