Abstract
The present investigation entitled “Standardization of PGR for enhancing the yield,
yield contributing traits and seed quality parameters in wheat (Triticum aestivum L.)
under sodic soil.” It consisted of 09 treatments, laid out in Factorial randomized block design
two variety (PBW-373 and NW-5054) with three replications. The results obtained from the
present investigation are summarized in this chapter. The treatments consisted of foliar spray of
plant growth regulators at two growth stages (vegetative and pre booting stage) along with
untreated control. Solutions were prepared on weight by volume (w/v) basis. The plant growth
regulators were positive effects on all the quantitative and qualitative characters like. Days to
50% flowering and days to maturity most effective treatment was found to be GA3 @ 100 ppm,
KNO3 @ 100 ppm, Salicylic acid @ 400 ppm. The maximum average plant height (cm) was
recorded in wheat varieties PBW-373, NW-5054 with GA3 @ 100 ppm fallowed by NAA @
100 ppm and IAA @ 100 ppm. The maximum average number of tillers per plant, number of
spikes per plant, number of spikelets per spike, 1000 seed weight and seed yield per plant was
recorded in wheat varieties PBW-373, NW-5054 with the Salicylic acid @ 400 ppm, KNO3 @
100 ppm, Salicylic acid @ 800 ppm. The maximum average length of spike (cm) was observed
in wheat varieties PBW-373, NW-5054 with the GA3 @ 100 ppm fallowed by NAA @ 100
ppm and Salicylic acid @ 400 ppm. The maximum average seed germination was recorded in
wheat all two varieties viz., PBW-373, NW-5054 with the GA3 @ 100 ppm , Salicylic acid @
400 ppm, KNO3 @ 100 ppm.
