Abstract
The experiment was carried out at the
research field and laboratory of Seed Technology Division, BARI, Gazipur during
rabi season of 2014-15 to find out the effect
of priming with phosphate solutions on seed yield and quality of maize. The experiment was laid out in
Randomized Complete Block Design with three replications. The tested eight
treatments were i) T1= Dry seed (control) ii) T2 =Water
primed for 16 hours iii) T3 = SSP (1% P) iv) T4 = SSP (1%
P) +20 g L-1KOH v) T5 = SSP (1% P) +25 g L-1
KOH vi) T6 = DAP (1% P) vii) T7 = DAP (1% P) +15 g L-1 KOH
viii) T8 = DAP (1% P) + 20 g L-1 KOH. Plant height,
Number of grains per cob, grain weight per cob, cob yield (kg plot-1),
grain yield (kg ha-1),
thousand grain weight, shoot height were found to be significantly affected due
to priming with phosphate solutions. Yield of maize was also increased in
response to P priming showing significant results in cob and grain yield.
Priming maize seeds showed increased grain yield over non-primed treatment,
however only the seed yields of T4 (4700 kg ha-1) was
significantly higher than that of (2602 kg ha-1). The lowest grain
yield was found in control treatments.
