Description A field experiment was conducted during rabi, 2010-11 at College of
Agriculture, University of Agricultural Sciences, Dharwad to study the effect of plant
growth regulators and chemicals on physiology, yield and quality in chickpea
genotypes. The experiment was laid out in spilt plot design with two genotypes viz.,
BGD-103 and JG-11 and ten treatments in three replications. The treatments included
three plant growth regulators and one chemical in two concentrations i.e. Progibb (20
and 40 ppm), CCC (500 and 1000 ppm), TIBA (100 and 200ppm) and salicylic acid
(50 and 100 ppm) as foliar spray. The PGR Progibb increased the plant height
significantly, whereas the growth retardants viz., CCC and TIBA resulted in reduced
plant height. The number of branches increased significantly with growth regulators
viz., TIBA (100 and 200 ppm) and CCC (500 ppm). The application of Progibb (40
ppm) hastened the days for flower initiation and 50% flowering. Significant increase
in the dry weight of leaf, stem, reproductive parts and total dry weight were observed
with the application of PGRs. The growth parameters viz., leaf area, LAI, LAD, SLW,
BMD, CGR, AGR, RGR and NAR increased significantly with CCC (500 ppm). The
foliar application of CCC (500 ppm) enhanced the biochemical parameters viz.,
chlorophyll ?a?, chlorophyll ?b?, total chlorophyll and NRA, while no significant
differences were recorded in seed protein content. The results on various yield and
yield attributes indicated that the entire yield contributing characters viz., seed yield
per plant, number of pods per plant, 100-seed weight and harvest index were
significantly higher with CCC (500 ppm) followed by TIBA (100 ppm) in both
genotypes. From the economic point of view, CCC (500 ppm) was more profitable in
terms of net returns.
