A pot experiment was conducted using two
contrasting chickpea varieties, viz., Pusa 362 (Desi type)
and Pusa 1108 (Kabuli type) with the objective of optimizing
dose of bio-regulators namely thiourea (TU), benzyladenine
(BA) and thidiazuron (TDZ). Varying doses of
foliar application of TU (0, 500, 1000, 1500 ppm), BA (0,
20, 40, 60 ppm), TDZ (0, 10, 15, 20 ppm) and salicylic
acid (0, 50, 100, 150 ppm) were applied before flowering
stage. Rates of photosynthesis were recorded at flowering
and podding stages and seed yield was obtained at harvest.
The results revealed that photosynthetic rate in both varieties
increased with increasing doses of bio-regulators at
both flowering and podding stages and grain yield also
exhibited similar trend. Highest photosynthetic rates and
grain yield were recorded with the foliar application of TU,
BA, TDZ and SA @ 1000, 40, 10 and 100 ppm, respectively.
After curve fitting, optimum dose for TU, BA, TDZ
and SA foliar application were estimated to be 878.33,
52.75, 11.78 and 90.63 ppm, respectively.
