Management during Planting/ Sowing
- For modan cultivation (upland crop)
and direct seeded crop in wet lands, apply nitrogen in three equal split
doses, first as basal dressing, second at tillering stage (three weeks
after seeding) and the third at panicle initiation stage (about thirty
days before flowering).
- Apply the full dose of P2O5 at the
time of land preparation as basal dressing.
- Apply K2O either in a single dose as
basal or in two split doses half as basal and half at the panicle
- In general, addition of lime is
absolutely necessary when the pH is lower than 5.5 and it is advisable
when pH varies between 5.5 and 6.5
- For direct seeded crops during the
first season, apply lime @ 600 kg/ha in two split doses, the first dose
of 350 kg/ha as basal dressing at the time of first ploughing and the
second dose of 250 kg/ha as top dressing about one month after sowing.
- For transplanted crop, apply lime @
600 kg/ha in two split doses, 350 kg/ha as basal dressing and 250 kg/ha
as top dressing about one month after transplanting.
- A time lag of one week should be given
between application of lime and fertilizers. For top dressing, lime may
be applied one week prior to the application of fertilizers.
- Apply organic manure in the form of
farmyard manure or compost or green leaf @ of 5 t/ha and incorporate
into the soil while ploughing. The entire quantity of phosphatic
fertilizers may be applied along with the organic manures.For
pre-planting application, apply the fertilizers at the final ploughing. It would be better to transplant 10-15 days
after incorporating organic manure.
- Cowpea may be raised as an intercrop
in dry seeded low land (semi-dry) rice by sowing 12.5 kg seed/ha along
with rice to serve as a source of green manure. When the rice field gets
submerged with the onset of southwest monsoon, cowpea at the age of
about six weeks and at active vegetative stage decays and gets
self-incorporated in the soil adding substantial quantity of green
manure. Such a system of concurrent growing of cowpea also reduces weed
pressure in semi-dry rice.
