Abstract
A field
experiment was conducted during
late
kharif
season of 2013-14 at the Agricultural Research Station. Navsari

of
pigeon pea genotypes for intercropping with sorghum under South
Gujarat condition"

clay soil.
Total seven treatments viz. T ,- sorghum + pigeonpea var .
Vaishali (2:1) , T2 -so rghum + pigeonpea var. GT- 102 (2:1), T,-
sorghum + pigeonpe a var. AGT- 2 (2:1), T 4 - sole sorghum var. GJ-38,
Ts- sole pigeonpea val'. Vaishali, T 6 - sole pigeonpea var . GT-I02 and
T,- so le pigeonpea va r. AGT-2 were evaluated in randomized block
design with four replications.

Different <:ropping systems did not significantly affect the
plant population of so rghum and pigeonpea. Sorghum sole cropping
(T.l recorded higher values of sorghum growth attributing characters
viz. plant height , dry matter accumulation and number of leaves perplant ovcr remaining treatments. [n case of pigeonpea, maximum
values or different growth attributes i.e. plant height was noted under
treatment T 6 (182.50 cm) and number of branches per plant was noted
under treatment
T7 ([ 1.80). Among different cropping systems,
sorghum sole cropping (T,) recorded higher values of length and girth
of earhead over the rest of treatments. Grain weight per earhead and
test weight of sorghum were recorded significantly higher under
treatment T4 (35.05 g and 26.85 g, respectively). Treatment Ts (182.50
and 4.57) remaining at par with T7 (175.71 and 4.25) was found
significantly superior in respect to number of pods per plant and
number of seeds per pod of pigeonpea, respectively. In case of 100
seed
\\ eight
of
pigeon pea,
treatment
T 6
(12.05
g)
recorded
significantly higher and which was at par with treatment T 2 (I 1.82 g).
Significantly higher grain and stover yield of sorghum were
noticed under treatment T, (3154 kg/ha and 13546 kg/ha, respectively)
which \\as at par with treatment T, (2865 kg/ha and 12569 kg/ha,
respectively). The harvest index of sorghum was found higher in
treatment
T,
(18.89
%).
Treatment
Ts
(1480
kg/hal
found
significantly higher seed yield of pigeonpea and which was at par with
treatment T6 (1334 kg/hal and T7 (1380 kg/hal and in case of haulm
yield, treatment T 6 (3848 kg/hal recorded significantly higher than
treatment T, (2820 kg/hal and T3 (2910 kg/hal. Maximum value of
harvest index of pigeonpea was noted with treatment T, (30.56%)
which "as at par with treatment Ts (30.36%) and T3 (28.98%).
Quality in terms of protein content and protein yield in
sorghum. maximum values were noted under treatment T 4 (7.98% and242.67 kg/ha, respectively) while in case of pigeonpea. maximum
values were noted under treatment T 5 (21.28 % and 316.07 kg/ha,
respectively).
Treatment T I
produced
significantly
superior sorghum
equivalent yield (6174 kg/hal which was at par with treatment T 3
(5825 kg/hal. In case of land equivalent ratio. treatment T I recorded
significantly higher (1.75 LER) and was par with treatments T2 and T3
(1.69
and
1.71
LER,
respectively).
Sorghum
intercropped
with
pigeonpea genotype Vaishali (T I) recorded maximum gross returns,
net returns and B:C ratio (89546 Rs/ha, 67011
Rs/ha and 2.97,
respectively) followed by treatments T 3 (84783 Rs/ha, 62248 Rs/ha
and 2.76, respectively) and T2 (82901 Rs/ha, 60366 Rs/ha and 2.68.
respectively). Minimum gross returns, net returns and B:C ratio
(46378 Rs/ha, 26394 Rs/ha and 1.32, respectively) were obtained
under treatment T 6.
On the basis of results obtained in present study it can be
concluded that intercropping of sorghum and pigeonpea var. Vaishali
in 2: I row proportion provide highest sorghum equivalent yield, net
returns and B:C ratio in sorghum and pigeonpea intercropping system
under South Gujarat condition.
