Cucumber
is the thermophilic and frost
susceptible crop. it is essentially a warm –season crop grown mainly in
tropical and sub tropical region, cucumber prefer slightly low temperature
compare to melon and hence it is grown extensively in sub tropical regions.
Light intensity and time of the day influences anthesis more than temperature
in cucumber but temperature has greater influence on another dehiscence and
pollen fertility.
The optimum temperature favoring anthesis and dehiscence is
13 degree centigrade to 18 degree
centigrade. never the less, for optimum vegetative growth and yield, the
temperature requirement is 18 degree centigrade to 24 degree centigrade .A well
drained loamy soil is preferred by cucumber. It is necessary that soil should
be fertile and well provided with organic manure, cucumber prefers a PH of
5.5—6.8(Hand book of Horticulture , Indian council of Agricultural r Reseach
new Dechi 5th july, 2001).
