Weed Management in Maize Plantation

A weed is any plant growing in a wrong place, usually considered undesirable. Uncontrolled weeds compete with the crop of interest for nutrients, moisture and space, and may completely suppress the crop if uncontrolled. They also harbour pests and diseases. Young maize seedlings can easily be overwhelmed by weeds. Weeds take full advantage of the wide rows and upright growth of maize, colonizing the bare soil beneath.

Weed Management in Cabbage

Any plant growing in a wrong or undesired place is considered a weed. Uncontrolled weeds compete with the crop of interest for growth factors like nutrients, moisture, and space, and may completely suppress the crop leading to low or no yields. They also harbor destructive crop pests and diseases. Cabbage crop does not compete well with weeds and is easily overwhelmed by their attack.

Weed Management in Beans

The common bean (Phaseolus vulgaris) is the most widely grown of the cultivated species of Phaseolus which is extremely important as food. However, the crop does not compete well with weeds because it grows slower compared to most weeds and can thus suffer from successive flushes of weeds, causing significant yield losses.

Weed Control in Orchards

Weeds are plants growing in the wrong place, which compete with the trees of interest for growth factors like moisture and nutrients. Some weeds are also alternate hosts of diseases, nematodes or insects pests. With this, it is therefore very important to keep the area under the canopy free of weeds.
