Abstract-An experiment was conducted for three successive
seasons (winter, summer and autumn), from Jan. to sept., at the
University of Khartoum Top Farm, Shambat, Sudan. The study
was aimed to evaluate the effect of spacing on growth parameters,
yield and oil content of mint during three successive seasons. In
row spacing were 20, 30 and 40 cm, and 70 cm between raw
spacing.The 20 cm in raw spacing resulted in the highest growth
parameters; plant height, number of leaves and herb production,
while in contrast, wider spacing (30 and 40 cm) promoted
branching without changes in oil content. Summer season proved
to be the best for growth, herb production and oil yield of mint
plants followed by autumn and winter.
