Abstract
The study was aimed to investigate the growth, instability and decomposition of onion in
Maharashtra. The data of area, production and productivity of onion pertaining to 30 years (1989-90
to 2018-19) were made available through the secondary source of NHRDF which was further
analysed using exponential function, Cuddy Della Valle’s Index and decomposition analysis model.
The results of the study disclosed that, there was positive and significant growth of area, production
and yield of onion during overall study period with annual growth rates of 8.43 per cent, 9.36 per
cent and 0.85 per cent, respectively. There was high instability during overall period for area and
production while, productivity showed a stability with low instability value of 12.89 per cent. The
decomposition analysis indicated that the area under onion cultivation played an important role for
the rise in production of onion with 62.80 per cent of area effect, 4.97 of yield effect and 32.21 per
cent of the interaction effect during overall study period. The results of decomposition analysis have
