Abstract
Cluster bean, [Cyamopsis tetragonoloba, (L.) Taub.] commonly
known as guar, is an important drought hardy leguminous crop of arid
and semi-arid areas. It is grown for various purposes, viz., vegetable,
green fodder, green manuring and seed. Now-a-days, it has acquired
the status of industrial crop because of high galacto-manan content
(gum) in the endosperm of its seed (28-33 %) which has multiple
industrial uses, viz., textiles, paper, petroleum, pharmaceuticals, food
processing,
cosmetics,
mining
explosives,
oil
drilling
etc.
thus making it a main foreign exchange earner. Being a leguminous
crop, its primary use is in soil health enrichment through atmospheric
nitrogen fixation, on average basis it has been estimated that it may fix
nearly 30 kg N ha -1 . Further, more the plant has a tendency to shed
most of the leaves at the time of maturity, it also increases the organic
carbon in the soil which also elevate organic carbon level that is the
major concern under the arid areas. Young pods of cluster bean are
used as vegetables for human being. It is a rich source of vitamin A,
calcium, iron, phosphorous and ascorbic acid for human being and
animals. Cluster bean provides very palatable and nutritious fodder as
a guar meal (feed) to the animals. It is a rich source of protein but low
in TDN values. Cluster bean fodder contains about 16-20 per cent
crude protein, 46 per cent TDN, 11-13 per cent DCP and more than 70
per cent digestibility on dry matter basis.
