Abstract
Studies were carried out to assess the impact of composted pressmud alone and in
combination with Rhizobium and Indole-acetic acid on cluster bean. A pot culture experiment
was conducted in red soil with cluster bean seeds. The investigation included 5 treatments
(T1, T2, T3, T4 and T5) using various combinations of composted pressmud, rhizobium and
Indole-acetic acid. A control (To) is maintained. The vegetative parameters like root length,
shoot length, number of nodules, number of leaves, plant fresh weight and plant dry weight
were significantly increased by all the treatments. T5 (pressmud 5 mg + 1% IAA) was
found to be most effective in increasing the biometric parameters. The yield parameters
were significantly increased by all the treatments.
