Objective:

To study the distribution and growth of weed species in the natural habitat of field crop areas

Introduction:

Field crops include maize, peanut, sweet potato, vegetables and rice. Field crops are among

major food crops in Malaysia, providing people of food source for daily consumption. They are

grown under several cropping system, thus creating many different situations or habitats for

weed growth. This therefore, allows many types of weed species to grow under field crop

situations. Weeds in the field and farm are mainly grasses, sedges and herbaceous

broadleaves. These weeds interfere with crops growth and yield through competition on light,

water, nutrient, space and canopy. As a result, crop growth will be affected such as being

stunted, further adversely effect yield quantity and quality.

Discussion:

1. What are the types of weeds species found for each crop/cropping system?Orchardgrasses, sedges, broadleaves

Rubber plantationgrasses, sedges

Oil palm plantationgrasses, sedges, broadleave

2. Is the weed composition the same when comparing with the previous crops you have

visited?

The weeds composition is different for each cropping system.

3. What are the common / dominating weed species and weed types for each field crop?

Orchard : Pennisetum Polystachion-grasses, Asystasia intrusa-shrub

Ruber plantation:Axonopus compresus-grasses, Praxelis clematidea-herb
