To examine the impact of plant growth regulators (PGR) on the phenology of Kabuli chickpeas. To perform cost/benefit analyses of the use of PGR on Kabuli chickpeas. To investigate relationships among yield components and phenological traits of chickpeas.


Results indicated that the use of plant growth regulators (PGRs) may not be a reliable cultural practice for controlling secondary crop growth in Kabuli chickpeas to improve seed yield and yield quality. The growth retarding effect on chickpeas gradually diminished after PGR treatment. The diminishing rate of PGRs is dependent upon PGR type, PGR concentration, growth condition and growth stage of the crop has been applied. Headline Duo® appears to have no significant impact on phenology of the chickpea, and also the fungicide appears to have no significant impact on the growth inhibitory effect of PGRs, when applied as a tank mix, as compared to tank mix with Proline®. The growth inhibitory effect of PGRs does change as a result of tank mixing with fungicides such as Headline®, Headline Duo®, and Proline®, as compared to the effect of PGRs applied alone.
