Apply 26 kg urea, 60 kg single superphosphate and 40 kg zinc sulphate heptahydrate (21% Zn) or 25.5 kg zinc sulphate monohydrate (33% Zn) per acre at sowing. Sow 8 kg seed by broadcasting on an area of 160 square meter (6.5 marlas) to raise nursery for one acre. To check the damage from birds, broadcast a thin layer of well-decomposed farmyard manure immediately after broadcasting rice seed. Keep the soil moist by irrigating the field frequently. Apply another dose of 26 kg urea per acre about a fortnight after sowing so as to get the seedlings ready for transplanting in 25-30 days. However, under forced circumstances, if nursery of about 45 days or above is to be transplanted, apply another dose of 26 kg urea after 4 weeks of sowing. In case, any insect attack or disease appears in the nursery, adopt the recommended plant protection measures. Irrigate the nursery regularly. The seedlings are ready when they are 20-25 cm tall or with 6 to 7 leaves.
If the seedlings in the nursery show the yellowing of new leaves, spray them three times with 0.5-1% ferrous sulphate solution (0.5-1.0 kg ferrous sulphate dissolved in 100 litres of water per acre) at weekly intervals. If the leaves turn rusty brown after becoming yellow, give a spray of 0.5% zinc sulphate heptahydrate solution (500 g zinc sulphate heptahydrate dissolved in 100 litres of water) or 0.3% zinc sulphate monohydrate solution (300 g zinc sulphate monohydrate dissolved in 100 litres of water per acre).
