Abstract
A field experiment was carried out at Agronomy Farm, B. A.
College of Agriculture, Anand Agricultural University, Anand, Gujarat
during the summer season of the year 2015 to study the “Effect of
time of sowing, row spacing and variety on summer cluster bean
under middle Gujarat conditions”. The soils of the experimental
plot was loamy sand in texture. The soil was low in organic carbon,
medium in available phosphorous and high in available potash. The
experiment was laid out in Split Plot Design with three replications.
The treatments comprised of three time of sowing viz., D1: (21st
January); D2: (1st February) and D3: (11th February) as main plot
treatments and combination of three different row spacings viz., S1:
30 cm; S2: 45 cm; and S3: 60 cm along with two varieties V1 (GG 1)
and V2 (GG 2) as sub plot treatments. In all, there were eighteen
treatment combinations.

Results revealed that sowing on 1st February (D2) remained at
par with sowing on 11th February (D3) gave significantly higher
number of plants per net plot at 15 DAS (213.56), plant height at 30
DAS (32.31 cm), 60 DAS (56.47cm) and at harvest (82.97cm) and test
weight (38.90 g) of cluster bean over sowing on 21st January (D1).
Crop sown on 11th February (D3) produced significantly the highest
branches plant-1 (6.01), pods plant-1(43.92), seeds pod-1 (7.96) and
pod length (9.11 cm) over early sowing on 1st February (D2) and 21st
January (D1). Similarly sowing on 1st February (D2) produced
significantly higher seed (1027 kg ha-1) and stalk (5043 kg ha-1) yield
which remained at par with sowing on 11th February (D3). Different
time of sowing did not exhibit any considerable impact on harvest
index.
Results revealed that growth attributes, yield attributes and
yield were significantly affected by different row spacing.
Plant sown at 30 cm spacing (S1) gave significantly the highest
number of plants per net plot at 15 DAS (266.94) and at harvest
(289.22), plant height at 60 DAS (55.96 cm) and at harvest (82.04
cm) and stalk yield (4859 kg ha-1) over rest of the treatments.
However, crop sown at 60 cm spacing (S3) being at par with 45 cm
spacing (S2) produced significantly higher pod length (8.24 cm) and
seeds pod-1 (7.13) over 30 cm spacing (S1). Plant height at 30 DAS,
branches plant-1, pods plant-1, test weight (g), seed yield (kg ha-1) and
harvest index (%) were remained unchanged due to different
spacings.

In the present experiment different varieties showed imperial
impact on all the growth parameters, yield attributing characters and
yield. Variety GG 2 (V2) proved statistically superior over variety GG1
(V1) in all the aspects barring periodical plant height and stalk yield.
Significantly maximum plant population at 15 DAS (206.44) and at
harvest (216.81), branches plant-1 (6.13), pods plant-1 (40.89), pod
length (9.28 cm), number of seeds pod-1 (8.07), test weight (41.86 g),
seed yield (1245 kg ha-1) and harvest index (26.59 %) were recorded
under variety GG 2 (V2) over GG 1 (V1) . On the other hand, variety
GG 1 (V1) exhibited higher plant height at 30 DAS (34.38 cm), 60
DAS (60.12 cm) and at harvest (88.39 cm) and produced higher stalk
yield (5392 kg ha-1) over variety GG 2 (V1).
Crop sown on 11th February with 30 cm row spacing (D3S1) had
significantly higher plant population (286.83) which remained at par
with crop sowing on 1st January with 30 cm row spacing (D2S1).
Sowing on 11th February with 30 cm row spacing (D3S1) also
recorded significant higher seed yield (1085 kg ha-1) which was found
at par with treatment combinations D2S3 (sowing 1st January with 60
cm row spacing) and D2S2 (sowing on 1st January with 45 cm).
Similarly significantly higher harvest index (22.05 %) was
obtained under treatment combination D3S1 (sowing on 11th
February with 30 cm row spacing) which remained at par with
treatment combination D1S3 (sowing on 21st January with 60 cm row
spacing) and D1S1.

Plant population at harvest, periodical plant heights, branches
plant-1, pods plant-1, pod length, seeds pod-1, and test weight and
stalk yield were not affected due to interaction D X S.
Treatment combination D3V1 (sowing on 11th February with
GG 1) being at par with treatment combination D2V1 (sowing on 1st
January with GG 1) recorded significantly higher plant height at 30
DAS (37.17 cm) and stalk yield (5589 kg ha-1). Significantly the
highest pod length (10.95 cm) and seeds pod-1 (9.84) were noticed
under treatment combination D3V2 (sowing on 11th February with
variety V2). Treatment combination D1V2 (sowing on 21st February
with variety GG 2) remaining at par with treatment combination D3V2
(sowing on 11th February with variety V2) obtained notably higher
harvest index (28.96%).
However, D X V was found identical for rest of the characters
viz; plant population at 15 DAS and at harvest, plant heights at 60
DAS and at harvest, number of branches plant-1, number of pods
plant-1, test weight and seed yield.
Treatment combination S3V2 (60 cm row spacing with variety
GG 2) produced significantly higher number of pods plant-1 (42.51)
and harvest index (28.02%). However, it seemed to be at par with
S2V2 (45 cm row spacing with variety V2) and S1V1 (30 cm spacing
with variety V1) for number of pods plant-1 and harvest index,
respectively.
Significantly higher seed yield (1327 kg ha-1) was received
under treatment combination S1V2 (30 cm row spacing with variety

GG 2) which was found at par with treatment combination S3V2 (60
cm row spacing with variety GG 2).
However, significantly maximum stalk yield viz. (6063 kg ha-1)
was recorded under treatment combination S1V1 (30 cm row spacing
with variety GG 1).
Interaction S X V remained impervious for plant population at
15 DAS and at harvest, periodical plant heights, number of branches
plant-1, pod length, seeds pod-1 and test weight.
The interaction between D X S X V was found trivial for all the
characters except seed yield of cluster bean, wherein, treatment
combination D3S1V2 (sowing on 11th February with 30 cm row
spacing with variety GG 2) recorded significantly higher seed yield
(1476 kg ha-1) which was found at par with treatment combination
D2S3V2 (sowing on 1st February with 60 cm row spacing with variety
GG 2).
Treatment combination D2S3V2 i.e. sowing of GG 2 variety on
1st February at 60 cm spacing incurred highest gross income of
`.65024 ha-1, net realization of `. 50667 ha-1 and BCR of 4.53,
followed by D3S1V2 i.e. sowing of GG 2 variety on 11th February at 30
cm spacing with gross income of `. 63468 ha-1, net realization of
`. 48511 ha-1 and BCR of 4.24.
