Abstract
Agriculture weeds are unwanted plants that grow along with crops and
compete for essential resources such as nutrients, water, sunlight, and space.
Agriculture weed can be any plant which incorporated with a particular crop it
may another crops, or native and non-native plants. Areca nut (Areca catechu)
or Adike is an important crop widely grown in Bhakatankatte Chikamagluru and
other regions of Karnataka. In areca nut fields, agriculture weeds are common
problem due to favourable conditions like shade and moisture. Aim of the
present work is to explore agriculture weeds in areca nut fields of
Bhakatankatte Chikamagluru through field survey. Total 17 agriculture weed
species Parthenium hysterophorus, Cynodon dactylon, Ipomoea obscura, Mikania
micrantha, Eleusine indica, Panicum repens, Amaranthus dubius, Portulaca
oleracea, Amaranthus viridies, Ricinus communis, Euphorbia heterophylla,
Spilanthus acmella, Lucas aspera, coccinea grandis, Mimosa pudica solanum
tovrum and Lantana camera belong to 16 genera and 10 families were
recorded. Among 17 species 08 found to be native and 08 were invasive weeds,
one is medicinal and one is found to be vegetable respectively. Some weeds like
Amaranthus viridies,
Amaranthus dubius, Portulaca oleracea and Coccinia grandis were used as vegetables and consumed throughout Karnataka. The
weeds were identified based on morphological features. The families Poaceae and
Asteraceae were represented by 3 species, Amaranthaceae and Euphorbiaceae
represented by 2 species, whereas Fabaceae, Lamiaceae, Portulacaceae,
Solanaceae, Lamiaceae and Verbinaceae represented by one species each. Habit
wise distribution of weed plants accounts for shrub (03), herb (07), climber
(02) and vine (01) respectively. The weather of Bhakatankatte Chikamagluru
favours growth of weeds because of low temperature, moisture and fertility of
soil. Management of agriculture weeds were necessary to control their rapid
spread throughout areca nut for yield loss.
