RAINFED RICE A SOURCEBOOK OF BEST PRACTICES AND STRATEGIES IN EASTERN INDIA<br />

During February-March, crop mixtures of ahu/aus and bao/aman are<br />

broadcast in the dry field so that ahu/aus can be harvested before<br />

flooding in DWS.<br />

88<br />

Preparation of neem extract-coated<br />

urea<br />

Add 10 ml of neem extract (available<br />

locally) to 1 kg of urea. Mix the extract and<br />

urea by hand until urea becomes pink.<br />

TIP<br />

Sow the seed when the soil<br />

has adequate moisture. The<br />

soil is ready for sowing when a<br />

piece of clod can be broken by<br />

pressing between fingers.<br />

Remove weeds by hand or bindha or ladder ( patta ) when the seedlings are<br />

30-35 days old.<br />

TRANSPLANTED RICE<br />

MIXED CROPPING OF AHU/AUS AND<br />

BAO/AMAN CROP<br />

Mixed seeds specific to these seasons<br />

are sown during February-March so<br />

that the short duration ahu/aus <strong>rice</strong><br />

can be harvested before flood occurs<br />

and the bao/aman continues<br />

thereafter.<br />

Methods of crop establishment<br />

and management (DWS)<br />

DIRECT-SEEDED RICE<br />

Prepare the fields well before the<br />

onset of monsoon by repeated,<br />

cross ploughing.<br />

Prepare neem extract-coated urea<br />

(NECU) using a locally available<br />

neem extract.<br />

Apply 50% of nitrogen as NECU<br />

and mix in the soil at final<br />

ploughing or apply a full dose of<br />

nitrogen as NECU at sowing.<br />

Drill the seeds in rows 25 cm<br />

apart. Alternatively, broadcast<br />

seeds at 90-100 kg/ha depending<br />

upon the situation.<br />

Apply 50% of nitrogen as NECU<br />

at tillering stage if water regime is<br />

favourable.<br />

Prepare the seedbed and raise seedlings about 45 days before the<br />

scheduled transplanting.<br />

Apply all the recommended NPK as basal dose at the time of final<br />

puddling and mix with the soil.
