Methods of Raising Rice Seedlings
Wet Bed Method
Wet nurseries are preferred under irrigated condition. The soil is puddle by two or three runs of puddle or three or four ploughings with local plough. After one or two days of puddling, divide the nursery area into narrow beds of 1.25 metre width and of any convenient length depending upon the slope. This facilitates sowing, weeding, spraying of chemicals and irrigation operations. Construct the drainage channels 30 centimeters wide in between the seed beds. Apply 225 g urea or 500 g ammonium sulphate and 500 g single super phosphate per 10 square meter. Uniformly broadcast about two or three handfuls of seed on a square meter of seed bed. Keep the seed beds saturated with water for first five days and then increase gradually the level of water up to 5 centimeters as the seedlings grow. Drain the excess water in periods of heavy rains during the first week of sowing. Adopt suitable disease and pest control measures. An application of 50 g of urea per square meter may be made by top dressing in case of nitrogen deficiency symptoms. In zinc deficient soils, give two sprays of zinc sulphate (5 kg zinc sulphate + 2.5 kg calcium hydroxide mixed in 1000 litres of water for one hectare), one 10 days after sowing and another 20 days after sowing. In case of iron deficiency 0.5%. ferrous sulphate solution should be sprayed. Seedlings would be ready for transplanting at an age of 20-25 days.
