The present investigation was aimed to study the effect of Kinetin and Abscisic acid (ABA) on leaf and nodule senescence in chickpea (Cicer arietinum L.) cv. CM88, in relation to the changes in the endogenous level of abscisic acid (ABA) and indole-3-acetic acid (IAA). Studies was carried out for study the involvement of hormonal and non-hormonal signal factors involved in nodule senescence, The critical period in the development stages for the initiation of nodule senescence. The correlation of leaf senescence with nodule senescence. The effects of the hormones were studied at four developmental stages; vegetative stage, flowering stage, early pod filling stage and late pod filling stage. The seeds of chickpea (Cicer arietinum L.) cv. CM88 were soaked for 6h prior to sowing in aqueous solution of Kinetin and Abscisic acid each at 10(5) M. Both the hormones at 10(6) M) were also applied as foliar spray during the vegetative phase of pant (4 weeks after sowing). The plants we
