Description :
Field experiment was conducted during the
rabi
seasons of 2015
-
16 at shankarnagar farm of
Agril. Botany Section, College of Agriculture, Nagpur to study the effect of foliar application of different
concentrations of putrescine (25, 50, 75, 100, 125 and 150 ppm) and naphthalene acetic acid (25 and 50
ppm) either individually or in combination
at one physiological stages (vegetative, 30
-
35 DAS) on
chemical, biochemical, yield and yield contributing parameters of chickpea (
Cicer arietinum
L.).
The field
experiment was laid out in Randomized Block Design
with three replication. The observations were
recorded at 25, 45, 65 and 85 DAS. The obtained results showed that 50 ppm NAA plus 100 ppm
putrescine significantly improved nitrogen, phosphorus, potassium, chlorophyll content in leaves and
protein content i
n seeds of chickpea. Yield contributing parameters viz., number of pods plant

were also significantly enhanced. Application of putrescine and/or NAA at
100 and 50 ppm respectively produced the highest number of pods which resulted in substantially the
highest seed yield. Putrescine and NAA increase the seed yield by 25.3% and 26.0%

respectively,
while the combination of 50 ppm
NAA plus 100 ppm
putrescine increased it by 33.2%. But, considering
the B : C ratio foliar application of 50 ppm NAA was found most effective treatment having B : C ratio of
5.9 as compared to 5.1 in cont
rol.
