Methods of Raising Rice Seedlings
This method of raising nurseries has been introduced in India from Philipines. It has been adopted by some farmers in Andhra Pradesh for raising seedlings. It saves almost half of the time in seedling raising. The main merit of this method is that less area is needed to raise seedlings. Twenty-five to 30 square meters of area is enough to raise seedlings sufficient for planting one hectare. The seedlings are raised faster in this method. The seedlings raised by this method are, however, very delicate and survive only for about two weeks. Besides, the seedlings are thin, slender and short in height. The seedlings when allowed to remain in the bed, may dry after two weeks.
In this method, beds could be prepared on an even but slightly raised (4 to 5 centimeres) surface in an open field or on even cement floor. About one square meter of seed bed should be required for every three kilograms of seed. A width of 1.5 meter has been found easily manageable. Cover the soil surface of the seed bed evenly and completely with banana leaves with the protruding midribs removed or preferably with plastic sheets. Carefully lay strips of banana bracts along the edge of the seed bed. Push thin bamboo pegs through the bracts into the soil to keep bracts upright and firm.
About 36 to 48 hours pre germinated seeds should be broadcast uniformly over plastic or banana leaves at the rate of three kilograms per square meter. Pack the seeds to make a uniform layer of three seeds thick. Do not press too hard on seeds. Follow this by sprinkling water gently. Sprinkle water three to four times a day up to four days to keep the seed bed wet. Thereafter cover it with one to two centimeters of water till end. Also press the seeds lightly once a day till fourth day and protect them from birds. Dapog seedlings would be ready for transplanting within 11 to 14 days of sowing. The seedlings thus raised can be rolled like a carpet with roots facing outside and carried to the transplanting site. Loosen the interlocked roots carefully before transplanting. Three to four seedlings should be transplanted per hill instead of two.
