ABSTRACT

An experiment was conducted to study the effect of eucalyptus trees on growth and yield of
American cotton. Plant height, root length and dry weight per plant increased with increase in
distance from Eucalyptus trees. However, due to adverse effect of eucalyptus trees cotton
plants did not produce any bolls upto a distance of 6-7m. Allelopathic effect of eucalyptus trees
reduced the kapas yields to 92% in plants at 7-8m away compared to 22-23m. Available
nitrogen and phosphorous in soils increased as the distance from eucalyptus trees increased both
in 0-30 and 30-60 cm soil depth. Similarly, moisture content of surface soil (0-15 cm) also
increased as the distance increased from the eucalyptus trees upto 12-14 m. Grasses, broad
leaved weeds and sedges were not present in the vicinity of eucalyptus upto a distance of 8-10
m. However, at a distance of 10-12 m away from eucalyptus trees, density of grasses, broad
leaved weeds and sedges and their dry weight increased as the distance increased upto a
distance of 22-24 m.
