Among Pulse crops cluster bean has a special contribution. It is
grown in Rajasthan, Gujarat, Haryana, Uttar Pradesh. In India
Rajasthan stands first in terms of area and production of Cluster bean.
The crop produces gum which is called guar gum and is exported in
foreign countries. Its seeds contain protein-18% and Fibre-32 % and
about 30-33 % gum in the endosperm.
Clusterbean is a tropical plant. It requires warm growing season. The crop requires 30 to 350C
temperatures at the sowing time for proper germination and 32 to 380C temperatures encourages
good vegetative growth, but high temperature at flowering stage photosensitive and
indeterminate crop. Atmospheric humidity encourages the infestation of many diseases like
bacterial leaf blight, root rot etc.
The Cluster bean is grown in medium to light textured soil having a pH of 7.0 to 8.5. Water
logged conditions affects the crop growth. Heavy loam soils are not suitable for cultivation of
cluster bean. Also the crop growth is affected in the high moisturized area.
After harvesting of rabi crop one deep ploughing from mould board plough or disk harrow
followed by 1-2 harrowing or ploughing and planking. Properly leveled field is required for good
Irrigation and Drainage
For good production of the crop one irrigation can be given at the time of flowering and pod
formation if crop suffers moisture stress. Cluster bean cannot tolerate water logging condition
therefore proper drainage is required in the field
The crop is sown in the first week of July to 25th July. Where irrigation facility is there the crop
can also be grown in the last week of June or after the onset of monsoon. During summer it can
be grown in the month of March.
