Limited availability of water in the seed bed may be a major factor
affecting yield. Other factors are seed maturation environment,
storage condition, depth of seeding, soil compaction and soil temperature.
|
|
During one season 12 inch (31cm) spacing between two lines
had yielded significantly higher numbers than either 15 or 18
inch spacing (38cm or 46cm), the increase in yield was rather
small. |
|
|
25cm spacing between two adjacent rows gave significantly
higher yield than 38cm spacing with medium grained varieties.
|
|
|
It is advantageous to adopt a wider spacing of 37 to 46 mm
between rows for this crop. |
|
|
From the economic stand-point it is better to keep a wider
spacing of either 15 cm of 20 cm between two plants within a
row. |
|
|
In Madras, 15 x 10 cm spacing has been found to be the optimum
for grain. |
|
|
In west Bengal, November sowing is found to give the best
yield. |
|
|
At Kharagpur, the line sowing has been observed to be better
than broadcast sowing. |
|
|
A higher yield of grain has been obtained with a spacing of
30 x 15 mm in case of the unmanured crop, and 30x30 mm in the
case of the manured one. |
Seedrate
Seed rate is 50-65 kg/ha. Treat the seed with rhizobium culture
to increase the yield by 20-25%.
Sowing
Seed drills of 6 tynes normally employed for drilling the seed in
lines covers 5-6 acres in a day of eight hours.
The spacing adopted is 30 cm between rows and 10 cm within the row
between plants.
